Brays nutrient mobility concept-DEVA ANIL.ppt
Bray proposed the nutrient mobility concept to explain how plant response to soil nutrients is influenced by how mobile the nutrient is in soil. Mobile nutrients like nitrates are extracted from a large root system zone according to Liebig's law, resulting in a linear response to increasing availability. Immobile nutrients like phosphorus are extracted from a smaller root surface zone, following Mitscherlich's law of decreasing returns. Bray combined these concepts to demonstrate how plant growth depends on both mobile and immobile nutrient availability within their respective extraction zones.

Nutrient recycling through agricultural and industrial wastes:potential and l...Pravash Chandra Moharana
Due to intensive agriculture, the soil resource is under increasing stress as there is a big gap between annual output of nutrients from soil due to crop removals and the nutrient inputs from external resources. So, filling this gap we go for nutrient recycling of non conventional resources i.e. agricultural and industrial wastes. On basis crop production, India generate about 312.5 Mt of crop residues, such as straw of cereals, oilseeds etc can supply about 1.13, 1.41 and 3.54 Mt of NPK. It has been estimated that all animal excreta can potentially supply 17.77 Mt of plant nutrients and 150 Mt of municipal wastes generated annually in India that have nutrient potential of about 1.72 Mt of NPK. At present India produces about 8.0 Mt of poultry manure which is sufficient to fertilizer about 3.56 Mha of land annually. These wastes are composted along with addition low grade rock phosphate and waste mica improve the quality of compost. A huge amount of effluents generated from tanning, textile, distillery and paper mill industries which contain several major primary and secondary plant nutrients (N, P, K, S, Mg, Ca, etc.) as well as micronutrients and heavy metals. Application of pressmud cake, FYM and poultry litter increase soil available nutrients and long term irrigation with paper mill effluent causes soil salinity and heavy metal accumulation. Industrial byproducts like phosphogypsum, basic slag etc used as soil ameliorant.Acidic soil

SOIL CARBON DYNAMICS UNDER INTENSIVE CROPPING SYSTEMVasantrao Nail Marathwada Krishi Vidyapeeth, Parbhani
Soil is the largest carbon reservoir pool of terrestrial ecosystem and plays a key role in the global carbon budget and greenhouse effect. It contains 3.5% of the earth’s carbon reserve as compared with 1.7% in the atmosphere , 8.9% in the fossil fuels, 1.0% in the biota and 84.95% in the oceans. Soil reserves about 1550 GT of carbon as Soil Organic Carbon (SOC) and 1700 GT as carbonate carbon (Soil Inorganic Carbon , i,e SIC).Soil carbon(C) plays an important role in exchange of CO2 between atmosphere and biosphere. SOC and SIC are important as it determine ecosystem and agro-ecosystem functions influencing soil structure ,soil fertility ,water holding capacity , cation exchange capacity and other soil characteristics.
CARBON SEQUESTRATION
Soil carbon sequestration involves transferring carbon dioxide from the atmosphere into the soil through crop residues and other organic materials. This process helps offset carbon emissions while improving soil quality and productivity. Management practices that maximize biomass addition and minimize soil disturbance, like no-till farming, are most effective for carbon sequestration. Increasing soil organic carbon provides benefits like increased agricultural productivity, improved soil structure and fertility, and enhanced water retention and infiltration. Adopting practices like adding organic amendments, reducing tillage, and using cover crops can help sequester carbon in cropland soils.

This document discusses the interactions between agriculture and the environment in India. It notes that agricultural productivity has greatly increased since the Green Revolution through high-yielding varieties, irrigation, and increased chemical use. However, this has also led to various environmental issues. Climate change is causing rising temperatures, uncertain rainfall patterns, and more extreme weather. Agricultural activities like rice cultivation, livestock, and fertilizer use contribute significantly to greenhouse gas emissions. Water resources are being polluted by industrial and agricultural runoff containing chemicals, sediments, and fertilizers. Soil quality is declining due to loss of organic matter, erosion, nutrient imbalances, compaction, salinization, and contamination from pesticides. These environmental changes and degradation are negatively impacting agricultural

Impact of climate change on weed and herbicide efficiency
This document summarizes a doctoral seminar presentation on the impact of climate change on weed and herbicide efficiency. Some key points:
1) Climate change will impact various elements of climate like temperature, rainfall, and humidity which can influence weed physiology and growth as well as crop-weed competition.
2) Rising CO2 and temperatures may benefit C3 weeds over C3 crops and C4 weeds over C4 crops by increasing their growth and biomass.
3) Climate change can reduce herbicide efficacy by impacting herbicide absorption, translocation and metabolism in plants through changes in photosynthesis, amino acid and lipid synthesis.
The effects of global climate change on agriculture(4)
This document summarizes the effects of global climate change on agriculture. It finds that agriculture contributes approximately 20% of annual greenhouse gas emissions through practices like deforestation, livestock production, and biomass burning. Rising temperatures and shifts in precipitation patterns from climate change will impact agricultural production globally and regionally. Effects may include changes in crop yields, suitable land areas, and increased pest/disease pressure. Adaptations can help mitigate these impacts to some degree but climate change poses risks for global and local food security.

Global food production now faces greater challenges than ever before due to changing climate, increasing land degradation and decreasing nutrient use efficiency. Nutrient mining is a major cause of low crop yields in parts of the developing world. Especially nitrogen and phosphorus move beyond the bounds of the agricultural field due to inappropriate management practices as well as failure to achieve good congruence between nutrient supply and crop nutrient demand (Pandian et al. 2014). Climate changes raised a serious issue of soil health maintenance for future generations. Rise in temperature and unprecedented changes in precipitation pattern lead to soil degradation by the erosion of top fertile soil, loss of carbon, nitrogen and increasing area under saline, sodic and acid soils. The climate is one of the key elements impacting several cycles connected to soil and plant systems, as well as plant production, soil quality and environmental quality. Due to heightened human activity, the rate of CO2 is rising in the atmosphere. Changing climatic conditions (such as temperature, CO2 and precipitation) influence plant nutrition in a range of ways, comprising mineralization, decomposition, leaching and losing nutrients in the soil. In order to meet the food demand of the growing population, global food production must be increased substantially over the next several decades. Sustainable intensification of agriculture, based on proven technologies, can increase food production on existing land resources. Therefore, conservation and organic agriculture, precision farming, recycling of crop residues, crop diversification in soils and ecosystems, integrated nutrient management and balanced use of agricultural inputs are the proven technologies of sustainable intensification in agriculture. More importantly, among the climate smart agricultural practices, the selection of appropriate measures must be soil or site specific for sustaining resource base for future generations. Further, presentation must be initiated to fine-tune the existing climate-smart agriculture to suit different nutrient management practices.Impacts of agriculture on the environment.
This presentation is based on the "negative impacts of agriculture on our environment.".

IRJET- Biogas Production from Municipal Solid Waste:- A Review
This document reviews biogas production from municipal solid waste via anaerobic digestion. It discusses key factors that affect biogas production such as temperature, pH, carbon-nitrogen ratio, total solids and volatile solids. The document reviews several past studies on biogas production from waste materials like cattle manure, fruit and vegetable waste, and municipal waste. It finds that biogas yield varies significantly depending on factors like feedstock used and digestion conditions. The maximum reported methane yield was 404 ml/g VS from wheat plant waste, while the minimum was 0.40 Nm3/kgVS from waste in Varanasi, India. Further optimization of digestion systems is needed to improve biogas production efficiency from municipal solid waste
Socio Environmental Impacts Of Agrofuel
This document summarizes the socio-environmental impacts of sugarcane ethanol production based on lessons learned. Sugarcane ethanol production can lead to soil degradation through erosion and compaction, as well as pollution of aquatic systems through sedimentation, pesticides, and waste. It can also increase nitrogen pollution through excess fertilizer runoff. Sugarcane burning causes additional soil and air pollution issues as well as health problems. Socially, it has impacted local farming and land use, increased tensions over land ownership, affected indigenous peoples, and often creates poor working conditions for laborers. Expanding agrofuel targets without proper sustainability criteria and oversight could exacerbate these problems. More sustainable, decentralized energy alternatives need to be pursued instead of

An economic analysis of precision application of lime at reduced rates
This document summarizes a study that analyzed the economic benefits of applying lime at reduced rates to soils in Zambia. The study used yield and financial data from on-station trials comparing plots with different lime and fertilizer application rates. The results showed that applying lime at reduced rates of 100-500kg/ha led to higher yields than plots without lime. Financial analysis found marginal returns over 150% when lime was combined with compost. Therefore, applying lime even at reduced rates can significantly increase profits for smallholder farmers in Zambia through yield gains.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.
The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.

Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
