This study aimed to 1) develop an LC-MS/MS method to quantify ionophores (MON, SAL, NAR) in poultry litter using a modified QuEChERS sample preparation, 2) quantify the levels of ionophores in poultry litter before and after three pilot-scale composting processes (aeration, turning, combination), and 3) identify transformation products of ionophores formed during composting using high-resolution LC-QToF/MS. The validation results showed good accuracy (71-119% recovery) and precision (19% RSD). Composting reduced ionophore levels by 13-68% depending on the conditions.

Flyashto composting
A pilot study was conducted at Washington State University to determine if composting coal ash would reduce storage and application problems. Test piles containing varying percentages of coal ash and cow manure were created. The study found that coal ash did not inhibit biological activity in composting and helped reduce the pH of the ash. Crop yields increased with higher percentages of coal ash in the compost. Metal analyses of the compost showed levels below regulatory limits, indicating the compost was safe for land application. The program will now fully compost campus waste with coal ash.

1) The study analyzed the effects of bovine urine and two varieties of Brachiaria grass on soil nitrogen dynamics, microbial activity, and greenhouse gas emissions over a 10-year field experiment in Colombia.
2) Results showed that Brachiaria humidicola produced more biomass and maintained higher populations of beneficial soil microbes like arbuscular mycorrhizal fungi and actinomycetes, compared to Brachiaria mulato and bare soil.
3) The presence of Brachiaria grasses, especially B. humidicola, led to lower nitrification rates and reduced nitrogen losses from urine patches through decreased nitrous oxide and ammonium levels over time.SBDposter-3
Samples of soil were collected from plots on a farm in Urbana, Illinois that had corn grown on them. Some plots had all corn residue removed after harvest, while other plots had no residue removal. The samples were tested for nitrate concentration. The results showed that plots with all residue removed had significantly lower levels of nitrate compared to plots with no residue removal. This supports the hypothesis that removing corn residue affects the amount of nitrate in the soil. Further research over multiple seasons and locations is needed to confirm these findings.

This document discusses an experiment on the effect of organic amendments on biochemical transformations under different soil conditions. The experiment analyzed soil properties like pH, EC, organic carbon, nitrogen, phosphorus, and potassium over 30 days after applying various organic amendments like farmyard manure, poultry manure, composted coir pith, and press mud to normal, alkali, and saline-alkali soils. The results showed that the organic amendments generally reduced EC and increased organic carbon and available nutrients compared to the control soils, with some variations between soil types and amendments. Using organic amendments improves soil health and properties while avoiding hazards of chemical fertilizers.

This study isolated and characterized a novel mycobacteriophage (bacterial virus) named Incognito from soil in Puerto Rico. Incognito was isolated from soil collected under a plantain tree and purified through plaque purification. Electron microscopy and SDS-PAGE gel electrophoresis were used to characterize the phage's morphology and protein profile. Incognito produced turbid plaques and had a concentration of 3 x 107 plaque forming units per mL. Its protein profile showed similarities to other mycobacteriophages. This study demonstrates that Puerto Rico's tropical environment supports diverse phage populations with potential applications in phage therapy.

This study analyzed the degrading effect of Glomus hoi and Pseudomonas aeruginosa on the organic content and heavy metals of oil refinery effluent polluted soil using Amaranthus cruentus as the test plant. This study was carried out to determine if agricultural activities can be improved using any or both of the micoorganisms. Eight different treatment layouts were used with three replicates for each level of pollution in the treatment layout. Ninety six (96) pots, each containing three kilograms of soil from both sterilized and unsterilized soil were used for the study. Fifty (50) grams of soil inoculum from propagated Arbuscular mycorrhiza was inoculated to a set of twenty four (24) experimental pots containing both sterilized and unsterilized soil before A. cruentus seedlings were transplanted to them. Another set of twenty four (24) pots containing both sterilized and unsterilized soil were injected with thirty (30) mL of P. aeruginosa inoculum solution before transplanting A. cruentus seedlings to them. The third set of twenty four (24) pots received dual inoculation of both fifty (50) grams of soil inoculum containing G. hoi and thirty (30) mL of P. aeruginosa inoculum solution before A. cruentus were transplanted to them. The residual twenty four (24) pots served as the control. Thereafter, pot preparation was arranged in the screenhouse in a randomized block design. The A. cruentus seedlings were raised in nursery for a period of two weeks before they were transplanted to the pots, seedlings were left for 3 days to overcome transplanting shock before contaminating the soil with refinery effluent at various concentrations of 0%, 2%, 4% and 6% v/w. The seedlings were allowed to grow for eight weeks before the termination of the experiment. The pre planting analysis of soil showed that heavy metals analyses (zinc and iron) of sterilized soil had a lower concentration to the unsterilized. The soil pH ranged from 6.3 to 6.8. It also revealed that organic matter and organic carbon content ranged from 0.8% to 1.3% and 0.4% to 1.7%. However, after the experiment, it was discovered in this study that treatments without any microorganism inoculation in sterilized and unsterilized soil had a higher level of % organic carbon and % organic matter content compared to the other treatments that were inoculated with one or two micro-organisms across all the levels of effluent concentration. Heavy metals of soil in all the soil samples were found to increase as the petrochemical effluent increased in concentration. The results obtained were analyzed using Duncan Multiple Range Test (DMRT) and other descriptive statistics. This study opined that the combined use of G. hoi and P. aeruginosa was more effective in improving the organic contentand the reduce heavy metals of oil refinery effluent polluted soil than when either is used singly.

Abstract— The current scenario encounters the steady demand of food supply and the application of fertilizer is become an indispensable in modern agriculture. Hence, the present study is focused on distribution of microbial and diazotrophic Azotobacter population in rhizosphere soil sample. Total microbial population viz, bacteria, fungi, actiomycetes and diazotrophic Azotobacter were enumerated from five different rhizosphere soil samples and compared the distribution of diazotrophic Azotobacter with other three microbial groups. The results of enumeration of total microbial population reveals that comparatively the bacterial population found to be higher followed by Azotobacter population in various rhizosphere soil. Based on the predominant growth, five Azotobacter strains (one isolate from each sample) were isolated and authenticated through morphological and biochemical characteristics. bio sp13
This document summarizes a pilot study that tested the biofermentation of water hyacinths and gizzard shad using Agron Corporation's technology. Four biofermentation trials were conducted using different mixtures of water hyacinths, gizzard shad, manures, and scallop offal. The results showed that water hyacinths alone do not ferment well but fermentation is improved when combined with other materials. A mixture of water hyacinths and gizzard shad resulted in odor and fly problems. The document recommends further studies to evaluate using the biofermentation products as fertilizers.

This study examined the effect of deficit irrigation on soil properties, physiology, and nutrient assimilation of sweet peppers. Three irrigation treatments were used: T1 (100% crop water requirement), T2 (90% CWR), and T3 (80% CWR). The results showed that higher irrigation amounts (T1) produced lower bulk density and higher porosity compared to the deficit treatments. Dry matter accumulation and harvest index decreased with greater water deficits. Nitrogen, phosphorus, and potassium uptake by the peppers also decreased as the irrigation amounts decreased. While deficit irrigation affected soil physical properties, the effects were not significant. However, available soil moisture had a strong influence on nutrient uptake by the crops.

This study examined the fodder yield, quality, and nutrient composition of silages from maize cultivated alone or intercropped with climbing bean in different spatial arrangements. Maize was grown alone or intercropped in arrangements of 1 row maize to 1 row bean, 1 row maize to 2 rows bean, or 2 rows maize to 1 row bean. The maize-bean intercrops had higher crude protein yields than maize alone due to contributions from the legume. After ensiling for 45 days, all intercropped silages had higher crude protein than maize silage alone. The 1 row maize to 2 rows bean intercrop silage had the highest levels of organic acids and ammonia-N among

This study evaluates the transformation dynamics of trenbolone acetate (TBA), an anabolic steroid used in beef cattle production that is a potent endocrine disruptor in aquatic life. Previous research discovered that TBA metabolites can reversibly transform between forms, depending on environmental conditions like temperature and pH. This reversible transformation has implications for the unexpected persistence and transport of TBA and suggests current occurrence data may underestimate bioactive steroid levels. The objectives of this study are to develop analytical methods to detect novel TBA photo-products, evaluate how reversible transformations impact transport risk, detect uncharacterized products in the field, and use modeling to predict impacts on agroecosystems. Key outcomes include optimized analytical methods and findings that reversible transformationsTabitha Mensah presentation ppt

The results of the study will help optimize irrigation for sweet pepper crops during times of drought or water abundance.
BIO LAB PRESENTATION (1)
The addition of phosphate fertilizer to a lotic water source had varying effects on water quality indicators. It significantly increased pH and turbidity as predicted. However, it did not significantly affect biochemical oxygen demand (BOD) or dissolved oxygen (DO) as predicted, though DO decreased slightly. The fertilizer appeared to slow the rate of BOD decrease. The results provide insight into how phosphate fertilizer runoff impacts natural waterways, though future, larger-scale studies are needed to better understand its full effects on water quality.

Bacterial and phytoplanktonic alkaline phosphatase activity (APA) was measured from
March to December 1998 in the mesotrophic Allal El Fassi reservoir located in a semiarid
zone (Morocco). The total APA varied between 0,107-1,780 mmol PNP·L-1·h-1. In
epilimnion, the bacteria contributed significantly (> 60%) to the total APA. In the meta
and hypolimnion, the APA was predominantly algal (> 58%). The absence of correlation
between APA and orthophosphates indicates that the hydrolysis caused by this enzyme
was not a significant process in the recycling of phosphorus in Allal El Fassi reservoir.
So, the APA was not a valid test of phosphorus deficiency.

This study aimed to investigate the effect of Oryctes rhinoceros larvae compost and vermicompost on the selected soil chemical properties. The soil was incubated with 0, 0.05, 0.10 and 0.15 % of these composts arranged in a Completely Randomized Design (CRD) with three replications. The experiment was carried out at the Faculty of Sustainable Agriculture, Universiti Malaysia Sabah. 100 mL of distilled water were added regularly to the soil-compost mixture throughout the incubation period. The soil-compost were sampled after one and four weeks of incubation. The samples were analysed for soil pH, soil electrical conductivity (EC), available P, total N and total C. Application of composts induced a positive effect on soil pH, and available P; soil pH increased from 6.29 (initial) to range 6.31-6.55, while available P of the soil increased from 1.39 mg kg-1 to range 1.73-2.02 mg kg-1. It was found that the capability of rhinoceros beetle larvae composts on the soil chemical properties have a similar effect with vermicompost. It made the insect compost are potentially beneficial for farm and can be profitable if commercially produced. It would also help in reducing rhinoceros beetle pests’ problem in oil palm plantation if this insects’ larvae were hunted for composting process.

The present study was carried on Abelmoschus esculentus (A. esculentus) by using the vermicompost. The decoction tea powder is wasted wet garbage and discarded on the dumping ground. It generally creates environmental pollution. This wet garbage can used as a good source of nutrients to the vegetable crop plants. The research is carried out by preparing vermicompost using 75% decoction tea powder and 25% mixture of black soil, cow dung, leaf litter and little vermicompost. The compost prepared by using decoction tea powder has increased concentration of necessary nutrients such as pH, minerals, organic carbon (O.C.), total phosphorus, potassium, calcium, magnesium and sodium required for vegetable crop plants for its development. In present investigation by applying this compost, Electrical conductivity was decreased by 9.51%, O.C. 89.30%, total phosphorus 26.09%, potassium 1.0%, Mg and Na by 43.17% shows a significant increase in absorption. It is also observed that germination period decreases whereas height of stem, leaf area, flowering and fruits were developed earlier than control soil.

Based on the predominant growth, five Azotobacter strains (one isolate from each sample) were isolated and authenticated through morphological and biochemical characteristics. bio sp13
This document summarizes a pilot study that tested the biofermentation of water hyacinths and gizzard shad using Agron Corporation's technology. Four biofermentation trials were conducted using different mixtures of water hyacinths, gizzard shad, manures, and scallop offal. The results showed that water hyacinths alone do not ferment well but fermentation is improved when combined with other materials. A mixture of water hyacinths and gizzard shad resulted in odor and fly problems. The document recommends further studies to evaluate using the biofermentation products as fertilizers.

This study examined the effect of deficit irrigation on soil properties, physiology, and nutrient assimilation of sweet peppers. Three irrigation treatments were used: T1 (100% crop water requirement), T2 (90% CWR), and T3 (80% CWR). The results showed that higher irrigation amounts (T1) produced lower bulk density and higher porosity compared to the deficit treatments. Dry matter accumulation and harvest index decreased with greater water deficits. Nitrogen, phosphorus, and potassium uptake by the peppers also decreased as the irrigation amounts decreased. While deficit irrigation affected soil physical properties, the effects were not significant. However, available soil moisture had a strong influence on nutrient uptake by the crops.

This study examined the fodder yield, quality, and nutrient composition of silages from maize cultivated alone or intercropped with climbing bean in different spatial arrangements. Maize was grown alone or intercropped in arrangements of 1 row maize to 1 row bean, 1 row maize to 2 rows bean, or 2 rows maize to 1 row bean. The maize-bean intercrops had higher crude protein yields than maize alone due to contributions from the legume. After ensiling for 45 days, all intercropped silages had higher crude protein than maize silage alone. The 1 row maize to 2 rows bean intercrop silage had the highest levels of organic acids and ammonia-N among

This study evaluates the transformation dynamics of trenbolone acetate (TBA), an anabolic steroid used in beef cattle production that is a potent endocrine disruptor in aquatic life. Previous research discovered that TBA metabolites can reversibly transform between forms, depending on environmental conditions like temperature and pH. This reversible transformation has implications for the unexpected persistence and transport of TBA and suggests current occurrence data may underestimate bioactive steroid levels. The objectives of this study are to develop analytical methods to detect novel TBA photo-products, evaluate how reversible transformations impact transport risk, detect uncharacterized products in the field, and use modeling to predict impacts on agroecosystems. Key outcomes include optimized analytical methods and findings that reversible transformationsTabitha Mensah presentation ppt
This document summarizes a study on the effect of deficit irrigation on soil properties, physiology, and nutrient assimilation of sweet pepper. The study used three irrigation treatments (100%, 90%, and 80% of crop water requirement) in a randomized block design. Data was collected on soil physical and chemical properties, dry matter accumulation, harvest index, and nutrient uptake. The results of the study will help optimize irrigation for sweet pepper crops during times of drought or water abundance.

The addition of phosphate fertilizer to a lotic water source had varying effects on water quality indicators. It significantly increased pH and turbidity as predicted. However, it did not significantly affect biochemical oxygen demand (BOD) or dissolved oxygen (DO) as predicted, though DO decreased slightly. The fertilizer appeared to slow the rate of BOD decrease. The results provide insight into how phosphate fertilizer runoff impacts natural waterways, though future, larger-scale studies are needed to better understand its full effects on water quality.

Bacterial and phytoplanktonic alkaline phosphatase activity (APA) was measured from
March to December 1998 in the mesotrophic Allal El Fassi reservoir located in a semiarid
zone (Morocco). The total APA varied between 0,107-1,780 mmol PNP·L-1·h-1. In
epilimnion, the bacteria contributed significantly (> 60%) to the total APA. In the meta
and hypolimnion, the APA was predominantly algal (> 58%). The absence of correlation
between APA and orthophosphates indicates that the hydrolysis caused by this enzyme
was not a significant process in the recycling of phosphorus in Allal El Fassi reservoir.
So, the APA was not a valid test of phosphorus deficiency.

This study aimed to investigate the effect of Oryctes rhinoceros larvae compost and vermicompost on the selected soil chemical properties. The soil was incubated with 0, 0.05, 0.10 and 0.15 % of these composts arranged in a Completely Randomized Design (CRD) with three replications. The experiment was carried out at the Faculty of Sustainable Agriculture, Universiti Malaysia Sabah. 100 mL of distilled water were added regularly to the soil-compost mixture throughout the incubation period. The soil-compost were sampled after one and four weeks of incubation. The samples were analysed for soil pH, soil electrical conductivity (EC), available P, total N and total C. Application of composts induced a positive effect on soil pH, and available P; soil pH increased from 6.29 (initial) to range 6.31-6.55, while available P of the soil increased from 1.39 mg kg-1 to range 1.73-2.02 mg kg-1. It was found that the capability of rhinoceros beetle larvae composts on the soil chemical properties have a similar effect with vermicompost. It made the insect compost are potentially beneficial for farm and can be profitable if commercially produced. It would also help in reducing rhinoceros beetle pests’ problem in oil palm plantation if this insects’ larvae were hunted for composting process.

The present study was carried on Abelmoschus esculentus (A. esculentus) by using the vermicompost. The decoction tea powder is wasted wet garbage and discarded on the dumping ground. It generally creates environmental pollution. This wet garbage can used as a good source of nutrients to the vegetable crop plants. The research is carried out by preparing vermicompost using 75% decoction tea powder and 25% mixture of black soil, cow dung, leaf litter and little vermicompost. The compost prepared by using decoction tea powder has increased concentration of necessary nutrients such as pH, minerals, organic carbon (O.C.), total phosphorus, potassium, calcium, magnesium and sodium required for vegetable crop plants for its development. In present investigation by applying this compost, Electrical conductivity was decreased by 9.51%, O.C. 89.30%, total phosphorus 26.09%, potassium 1.0%, Mg and Na by 43.17% shows a significant increase in absorption. It is also observed that germination period decreases whereas height of stem, leaf area, flowering and fruits were developed earlier than control soil.

The aim of this study was to determine the protein composition of pigeon pea Cajnus cajan (L)
millspaugh treated with sodium azide and gamma radiation. This was performed by exposing the seeds of
landraces pigeon pea to gamma rays at Centre for Radiotherapy and Oncology Department, ABUTH, Shika,
Zaria at doses of 0(control), 50, 100, 150 and 200Gy. These seeds were further treated with sodium azide
(NaN3) concentrations at 0.00, 0.01, 0.02, 0.03 and 0.04% SA. The analysis of protein content was the
determination of the amount of reduced Nitrogen present in food substance, i.e., its –NH2 and =NH2. The
proximate analyses were carried out as recommended by the Association of Official Analytical Chemists
(AOAC, 1990) using the kjeldahl method. The highest crude protein (CP) percentage value was obtained from
150Gy + 0.03%SA (25.1 %), followed by that due to 100Gy + 0.01%SA (24.7 %), 100Gy + 0.04%SA (24.4 %),
100Gy + 0.03%SA (23.7 %) and 150Gy + 0.00%SA (23.6 %). It is, therefore, concluded that the two mutagens
significantly affected the pigeon pea plant composition.

The effect of three types of bio fertilizers ( N, P and K), plant and animal compost on soil arthropod diversity and species abundance were studied in organic tomato field. Nitrogen fixation bacteria increased the insects population with 16.26%, and the total population of soil arthropods with 7.3% and caused reduction % in mites and other arthropods population with 66.53 and 100 % reduction. Fertilization with potassium soluble bacteria (K) increased the population of insects, mites, and the total population of soil arthropods systemic groups with 175, 1353.8 and 741.23 % respectively. Similar results were achieved in the treatments with phosphorous soluble bacteria (P)
The treatments with animal compost increased all soil arthropods systemic groups, insects, mites and the total population of soil arthropods systemic groups gave 486.48, 356.36 and 347% increasing percentages compared with pretreatment. While this treatment caused reduction in the other soil arthropods with 66.6%.
The two types of compost increased both the terrestrial soil arthropods systemic groups, which collected by pitfall traps , and the superficial soil arthropods systemic groups that found in the upper surface layer, until (30cm depth), which collected by Berlese funnel methods, with percentage arranged from 47% to 61% in animal compost.
Generally steep decline occurred in other arthropods in tomato organic cultivated after application of different bio-fertilizers and increased in insect population, mites and total population of soil arthropods collected with pitfall traps and Berlese funnel.

Effect of Particle Size Distribution of Perlite and its Mixture with Organic Substrates on Cucumber in Hydroponics System. A zeolite mineral is a crystalline substance with a structure characterized by a framework of linked tetrahedra, each consisting of four O atoms surrounding a cation. This framework contains open cavities in the form of channels and cages. These are usually occupied by H2O molecules and extra-framework cations that are commonly exchangeable. The channels are large enough to allow the passage of guest species. In the hydrated phases, dehydration occurs at temperatures mostly below about 400 °C and is largely reversible. The framework may be interrupted by (OH, F) groups; these occupy a tetrahedron apex that is not shared with adjacent tetrahedra.

The Content of Agar Seaweed Gracilaria verrucosa Fertilized with Vermicompost
The economic value of seaweed G. verrucosa depends on the content of the agar it has. Cultivation Gracilaria verrucosa generally use inorganic fertilizers that are not environmentally friendly, inorganic fertilizer is not a wise step considering the recent increase in consumers who want a product that is free of pesticide residues. The purpose of this study was to analyze the optimal dose of vermicompost fertilizer to produce high quality of agar rendement, viscosity and gel strength seaweed Gracilaria verrucosa. From the result of the research, it was found that the quality of agar rendement, viscosity and gel strength were normal and homogeneous distribution (p>0,05). Then the ANOVA test showed that the fertilizer treatment gave a significant effect on the quality of agar rendement and viscosity (p <0,05), while the quality of agar gel strength did not give significant effect (p> 0,05). The highest level of viscosity and rendement of Gracilaria verrucosa seaweed was found in treatment A and the lowest in treatment F (control). The highest level quality of agar gel strength Gracilaria verrucosa was found in treatment F compared with other treatment.

Types of plant cultivars and seasons often affect production and productivity of fodder biomass and nutritional quality to animals. Selection of suitable cultivars and better understanding of year round biomass production are indispensable for improving quality feed supply to animals. Black Seed Moringa (BSM-L) and White Seed Moringa (WSM), the two local cultivars and Black Seed Moringa (BSM-T) cultivar of Thailand origin of Moringa oleifera were cultivated in the fodder research field of the Bangladesh Livestock Research Institute (BLRI) during the period of 19 August 2014 to 23 December 2015. An agronomical trial was conducted to determine the biomass yield of the three cultivars in different seasons of a year under common agronomical practices. The effect of the cultivars on the daily relative growth rate (RGR), chemical composition and in-sacco dry matter (DM) degradability were also evaluated. The cultivar response to biomass production performances, chemical composition and nutritional values were analyzed in an ANOVA of a Randomized Block Design (RBD), while the differences in the rate and extent of the DM degradability in-sacco determined using three rumen cannulated bulls were analyzed in an ANOVA of 3x3 Latin Square Design. The annual biomass yield of BSM-L tops (114.5 t/ha fresh; 22.7 t/ha DM) was significantly higher than that of WSM (29.0 t/ha fresh; 5.80 t/ha DM) or BSM-T (83.5 t/ha fresh; 16.0 t/ha DM). No significant difference in chemical composition (224.9, 222.4 & 223.8 g.kg-1 DM of crude protein (CP), respectively, and 450.9, 455.3 & 435.4 g.kg-1 DM of neutral detergent fiber, respectively) or nutritional value (47.4, 46.7 & 45.3% of potential, and 62.8, 64.2 and 63.6% of effective degradability of dry matter) was found for the cultivars. BSM-L had a significantly higher survivability (97.2%), prune number per plant (3.50) and RGR (15.6 mg DM/day) than WSM (25.0%, 2.30 & 4.20 mg DM/day) or BSM-T (55.6%, 3.10 & 10.8 mg DM/day) respectively. The hot and dry, and hot and humid climate having a Heat Index (HI) range of 25o to 35o F and monthly total rainfall of 130 mm to 332 mm were suitable for cultivation of all the Moringa cultivars. It was concluded that considering biomass production and its quality in terms of chemical composition and nutritional values, Black Seed Moringa (Moringa oleifera) may be cultivated as a plant fodder crop for the production of feed for ruminant animals.

The aim of the present study was to explore the potential for using aloe vera wastes as amendment for soil to improve its fertility. Soil was exposed to four concentrations of aloin (rich in HAP) for 0, 7, 14 and 28 days. Physico-chemical parameters were analyzed: soil Ph, organic matter (OM), nitrogen, phosphorus, and cation exchange capacity (CEC). The activity of seven enzymes implicated in the C, N and S cycles were measured. Microbial Biomass was determined by the method of substrate induced respiration. BiologEcoplates (Biolog Inc., Hayward, CA) were used to estimate soil microbial functional diversity. Our findings suggested a decrease on phosphorus and nitrogen content and an increase on CEC after aloin addition. Also, a decrease on microbial biomass and enzymes activities was observed, except for FDA. Ecoplates results demonstrate a decrease on microbial activities depending on the incubation time. Moreover, our results indicated that bacterial communities of the tested soils have more affinity to consume substrates as Amino acids and polymers. Our results should be carefully considered in view of the agriculture waists reuse for a sustainable agriculture

Diversity of halophilic mycoflora habitat in saltpans of Tuticorin and Marakk...Open Access Research Paper
Highly diverse biological system of solar salterns with different salinities, often provide high densities of mycofloral populations, makes the salterns excellent model systems for both its diverse and activity. In this study, diversity of halophilic fungi in six stations which includes reservoir, evaporator and crystallizer pond of both Marakkanam and Tuticorin saltpans in relation to environmental parameters were carried out for a period of two years. 95 species of halophilic fungi from water and sediment samples belongs to 41 genera were recorded in both saltpans. Aspergillus and Penicillium species were recorded as dominant, vast differences in growth of each isolate at different salt concentrations in the ponds were observed. This paper also elucidated the slight fluctuations in physico-chemical parameter among the ponds with respect to seasonal variations were also recorded.
Effects of renewal pattern of recycled nutrient solution on the ion balance i...
Ion imbalance in recycled nutrient solutions is caused by selective ion uptake of plants, which occurs at different
rates in different growth stages. The objectives of this study were to investigate the ion balances in both recycled nutrient
solutions and rockwool media using different renewal patterns for the nutrient solutions, and to analyze the subsequent effects
on uptake of water and nutrients. Over 12 weeks of paprika cultivation, two different renewal patterns (week units) of 6-4-2
and 8-2-2 weeks were compared with a constant renewal pattern of 4-4-4 weeks (control). The nutrient solution in the reservoir
tank was constantly maintained at EC 2.5 dS･m
-1
and pH 5.5-6.5. The changes in the ion balance with the 4-4-4 week pattern
were smaller than those with the other treatments. In the early growth stage, however, the ion balances similarly changed
among all treatments. Greater changes were subsequently observed for the 6-4-2 week pattern. Although fruit yield and shoot
fresh weight of paprika were the lowest with 6-4-2 renewal pattern, no significant differences were observed. Our results indicate
that renewal intervals can be extended in consideration of growth stage for more efficient and practical operations in closed
soilless cultures.

Ondo State has the largest production of cocoa in Nigeria, cocoa pod on most cocoa plantation in the state are usually left as an environmental nuisance on the cocoa plantation. Effect of compost made from decomposing cocoa pod and animal dung on the yield of maize crop were investigated for nine weeks. Cocoa pods were decomposed using animal dung (poultry droppings, pig and cow dung) in ratio 3:1 of cocoa pod to each of the animal dung. Cocoa pod and poultry droppings mixture has the highest bacterial, fungal and yeast population of 2.6 x106 – 2.9 x 106 (cfu/ml), 8.4 x105 – 9.2 x 105 (sfu/ml) and 4.0 x104 – 12.0 x 104 (cfu/ml). It also had the highest moisture content (88.81%) and temperature (350C) among the composting materials. Fifteen bacteria and thirteen fungi were isolated during the decomposition; common microorganisms that occur throughout decomposition were Bacillus sp, Pseudomonas sp, Escherichia coli, Staphylococus aureus, Serratia Sp, Fusarium sp, Mucor sp, Tricoderma sp, Aspergillus sp, Cladosporum sp and Neurospora sp. The pH of decomposing samples ranged from 6.10 to 7.81 at the initial stage of decomposition and pH of 7.79-9.07 at maturity of the compost. Poultry cocoa compost has the highest NPK (nitrogen, phosphorus and potassium) content of 1.345, 7.955 and 23.016 (mg/kg) respectively. Experimental setup was carried out in the field and in the screen house which the cocoa pod compost and NPK fertilizer was use to plant yellow and white maize. The compost fertilizer had a better better output than the NPK fertilizer. Height-350cm, grithy-8cm, cob-15 (big and strong) colour of maize plant (deep green leaves) while height-320cm, grith -4cm, cob-10 (small and colour of maize plant (greenish yellow leaves) for the cocoa compost and NPK fertilizer respectively were at the field Cocoa pod and poultry droppings mixture has the highest of the yellow and white maize (136cm and 126cm) respectively while the NPK sample has the lowest height of 55cm and 50 cm respectively of yellow and white maize.

Agronomic viability of arugula, A functional vegetable, under the residual ef...Open Access Research Paper
Arugula is a nutritionally rich vegetable. Considered a functional food, it can be used to treat diseases and improve clinical conditions. This work was conducted at the Rafael Fernandes Experimental Farm, in the Alagoinha district, rural area of Mossoró-RN, from December 2016 to February 2017, with the objective of evaluating the agronomic viability of arugula, functional vegetable under the residual effect of species of the semi-arid region. The experimental design was the complete randomized blocks with treatments arranged in a 5 x 3 factorial scheme, with three replications. The first factor was constituted by four green fertilizer (0.0, 0.8, 1.6, 2.4, 3.2kg m-2 dry basis) and second factor by the types of green fertilizers (Merremia aegyptia, Calotropis procera and Senna uniflora). Initially radish was planted in plots of 1.4 x 1.4m. After the crop was withdrawn, the arugula cultivated Cultivada was planted. The evaluated characteristics were: height and number of leaves per plant, yield; number of sauces and dry matter mass of the aerial part. The best agronomic performance of the arugula was observed in the amount of 2.4kg m-2, with yield of 902.3g m-2 and 30 arugula sauces. Among the types of fertilizers, Merremia aegyptia presented statistical superiority in relation to Calotropis procera and Senna uniflora for yield and number of sauces. The incentive for the cultivation of arugula is important because its benefits are directly related to the farmers who produce and also commercialize, and the consumers who acquire this vegetable.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
