To achieve sustainable agricultural production it is imperative to explore alternative integrated soil and nutrient management systems with minimum environmental degradation. Integrated Nutrient Management (INM) aims at maintenance or adjustment of soil fertility and plant nutrient supply to an optimum level for sustaining the desired crop productivity through optimization of benefit from all possible sources of plant nutrients in an integrated manner (Roy and Ange, 1991). Continuous and imbalanced use of fertilizers under intensive agricultural cultivation had adverse impact on the soil. Use of bio and organic fertilizers and adherence to ecofriendly land management practice enhances crop production and sustains soil fertility (Sailaja and Usha, 2002). Keeping these in view, INM practice is seen as a viable option in restoring the soil physical structure and chemical fertility, improving soil organic C and therefore, sustaining the system productivity. Sources such as nitrogen fixers, phosphate solubilizers, mycorrhize and other beneficial organisms contribute to enhance efficient uptake of plant nutrients (Gupta et al., 2003).
INM tries to reduce the need for chemical fertilizers by taking advantages of non-chemical sources of nutrients such as the manures, composts and bio-fertilizers (Gopalasundaram et al., 2012). Bio-fertilizers application not only increases plants growth and yield, but increase soil microbial population and activity; resulting in improved soil fertility (Ramesh et al., 2014). They include free-living bacteria which promote plant growth even in polluted soils. Azospirillum, Azotobacter, Pseudomonas, Bacillus and Thiobacillus are examples of these bacteria (Zahir et al., 2004). Niess (2002) reported that plant growth promoting bacteria reduced the toxicity of heavy metals and increased plant growth and yield.
Apart from this, agroforestry interventions through integration of suitable trees, soil improvement through cover cropping, soil and water conservation measures etc can be potential INM strategies that can be practiced to sustain yield, minimize risk, utilize the lag phase, and improve productivity (Rao, 2000). The success of INM depends on the judicious use of the right combination of INM component suitable for a particular land use system.

Vermicomposting and vermiculture are two terms that are used interchangeably, but they actually mean two different things. Vermicomposting is the practice of composting using redworms or another type of earthworm to accelerate the natural process of decomposition. Vermiculture, on the other hand, refers to raising redworms or other earthworms as food for pets or livestock; the worms themselves can be used to create fertilizer. The information in this guide will help you understand what vermiculture and vermicomposting are.

Vermicompost is nothing but the excreta of earthworms, which is rich in humus and nutrients. We can rear earthworms artificially in a brick tank or near the stem/trunk of trees (especially horticultural trees). By feeding these earthworms with biomass and watching properly the food (bio-mass) of earthworms, we can produce the required quantities of vermicompost.

Toxicity is a function of solubility. Insoluble compounds as well as the metallic forms often exhibit negligible toxicity. The toxicity of any metal depends on its ligands. Heavy metal toxicity can result in damaged or reduced mental and central nervous function, lower energy levels, and damage to blood composition, lungs, kidneys, liver, and other vital organs.

International Journal of Engineering Research and Applications (IJERA) is an open access online peer reviewed international journal that publishes research and review articles in the fields of Computer Science, Neural Networks, Electrical Engineering, Software Engineering, Information Technology, Mechanical Engineering, Chemical Engineering, Plastic Engineering, Food Technology, Textile Engineering, Nano Technology & science, Power Electronics, Electronics & Communication Engineering, Computational mathematics, Image processing, Civil Engineering, Structural Engineering, Environmental Engineering, VLSI Testing & Low Power VLSI Design etc.
In recent years, it is no doubt that in India, where on one side pollution is increasing day by day due to accumulation of organic waste and on the other side there is a great shortage of organic manure.
It has been estimated that India, as a whole, generates as much as 25 million tonnes of urban solid waste of diverse composition per year. Solid waste comprises of both organic and inorganic matter.
Under the present condition of environmental degradation, vermicomposting technology is the best way to meet all the requirements of the society. This is a process of recycling trash/agricultural wastes in an efficient and eco-friendly manner in order to produce quality compost.
Organic wastes can be broken down and fragmented rapidly by earthworms, resulting in a stable non-toxic material with good structure, which has a potentially high economic value and also acts as a soil conditioner for plant growth.
It is a type of composting in which worms eat and metabolize organic matter that comprises to a better end product known as Vermicast (commonly called as BLACK GOLD) which has a stuff of nutrients that can be directly incorporated into the soil to help with plant fertilization, soil enrichment and soil stability.From a social point of view, organic fertilizers will:
Improve the social status of the individuals and the community.
Create motivation for people to live in the countryside by providing job
opportunities and business plans.
From a hygienic point of view, organic fertilizers will:
Produce chemical-free crops which will improve people's health.
Reduce the danger of lung diseases and other diseases resulting from burning the organic wastes in the field.EPIGEIC EARTHWORMS:
Earthworms of this group cannot make burrows in the soil. They can only move through crevices of the surface. They feed exclusively on decomposing organic wastes.
ENDOGEIC EARTHWORMS:
They are subsoil dwellers. Secretions of body wall of earthworms cement and smoothen the walls of the burrows and protect the wall from collapsing easily. They move below 30cm or more in the soil
ANECIC EARTHWORMS:
They are found in the soil, which is not frequently disturbed. They make very complicated burrows in the sol and they firmly pack their burrow walls with their castings. The Anecic earthworms like Epigeic earthworms are commonly found in temperate countries.Vermicompost is an excellent soil additive made up of digested compost. Worm castings are much higher in nutrients and microbial life and therefore, are considered as a higher value product. Worm castings contain up to 5 times the plant available nutrients. It not only adds microbial organisms and nutrients that have long lasting residual effects, it also modulates structure to the existing soil, increases water retention capacity. Vermicompost contains an average of 1.5% - 2.2% N, 1.8% - 2.2% P and 1.0% - 1.5% K. The organic carbon is ranging from 9.15 to 17.98 and contains micronutrients Nitrogen, phosphorus, Potassium..
Vermicompost - An Organic Gold (Vermiculture and Vermicompost, Earthworm Farm...Ajjay Kumar Gupta
Vermiculture is the culture of earthworms. The goal is to continually increase the number of worms in order to obtain a sustainable harvest. The worms are either used to expand a vermicomposting operation or sold to customers who use them for the same or other purposes. Vermicomposting is the process by which worms are used to convert organic materials (usually wastes) into a humus-like material known as vermicompost. The municipal wastes; non-toxic solid and liquid waste of the industries and household garbage’s can also be converted into vermicompost in the same manner.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Introduction
Under present day condition, it becomes very essential to protect environment from further
degradation, develop appropriate technologies for use in recycling various organic waste and
to harness energy thus minimizing environmental stress. Vermitechnology is a promising
technique that has shown its potential in certain challenging areas like augmentation of food
production, waste recycling, management of solid wastes etc (Tripathi et al., 2005). The word
Vermiculture biotechnology implies a modern technique of harnessing the ecosystem for
effective utilization of the organic waste with the help of earthworms, which results into
generation of useful organic manure. It helps to avoid the environmental pollution and
expenditure of resources to treat the organic waste (Singh, 2004). A large volume of organic
matter generated from agriculture activities, dairy farm, industrial establishments, animal
shelters and household activities are dumped to putrefy without proper utilization. Wastes are
the misplaced valuable resources, which can be utilized by proper composting. The
composted waste, the vermicast which has higher qualities of manure can be used to feed our
“Nutrient-organic matter-hungry” soils (Ismail et al., 2003). Vermicompost is considered
superior to other types of compost because of its quality. Soils with vermicasts have roughly
100 times more bacteria than soil without worms. Moreover plant growth promoting
substances have been reported to be present in vermicasts.
Vermicompost for Organic Farming - an Eco-Friendly Approach
The increase in human population and urbanization has led to food scarcity. To increase food
production agriculturalists are tempted to use more amounts of chemical fertilizers and
pesticides frequently, which cause several hazards to soil microflora, which in turn affects
fertility. For instance chemical fertilizers like Ammonium sulphate, Ammonium chloride and
Urea reduce the soil pH. Chlorides are highly toxic to most of the crop plants. The
accumulation of chemicals by biomagnification in plants and their products causes several
diseases in human beings. Infant disease such as methanoglobinaemia is caused due to
nitrogen containing fertilizers. The residues of chemical fertilizer cause concern over the
safety of food and sustainable production. Hence, it becomes imperative for the researchers
and planners to develop an alternative viable strategy to counteract the problem.
Organic farming, usage of eco-friendly manures such as green manures, urban waste, rural
wastes, etc. can bring sustainability to agriculture. Vermicomposting is an eco-friendly,
economical, efficient novel technology that can be applied to utilize agricultural and other
organic wastes. This technology also provides opportunities for self-employment for rural
people, by utilizing the available agricultural resources. The technology had begun in Ontario,
Canada in 1970 and now is practised in countries such as USA, Japan and Phillipines. In
India, vermicomposting technology is getting familiarized in this decade. A number of
agro-industrial organic wastes discarded as unusable, which contain essential nutrients can
be exploited to improve the physical, chemical and biological properties of soil. The digested
2. product of earthworm known as castings, which is rich in nutrients such as phosphorous,
potassium, calcium and magnesium increases the soil fertility.
Advantages of Vermicompost
Potential environmental benefits of Vermitechnology include: reduction of noxious qualities of
organic wastes, elimination/reduction of harmful micro organisms; conversion of agro-wastes
into high value fertilizer and production of food and feed from food discards (Tripathi et al.,
2005). Vermicompost envisages the soil fertility for years together with out affecting the food
quality. The NPK content of vermicompost is higher than the farmyard wastes (FYW).
Nutrients Vermicompost
Farm yard wastes
(FYW)
Nitrogen (N) 0.5 % 0.18 %
Phosphorous
(P)
0.57 % 0.2 %
Potassium (K) 3.14 % 0.5 %
Sujatha et al. (2003) reported earthworm castings in the home garden often contains 5 to 11
times more Nitrogen, Phosphorous and Potassium than the surrounding soil. Castings of
earthworm also contain abundant sources vitamins, antibiotics and enzymes such as
proteases, amylases, lipases, cellulases and chitinases. Vermicompost technology can
provide employment to millions of youth, can eliminate dependence on chemicals; can convert
wastes into fertilizer; can bring waste land under cultivation, can feed hungry citizen and can
make a country green and prosperous in a span of just a few years (Shewta et al., 2004). This
technique also helps to conserve the biodiversity, which is the need of the hour. Apart from
providing self-employment opportunities for the weaker section and profitable agricultural
waste utilization it will also help in maintaining the environmental/ecological balance.
Vermicomposting for Indian Conditions
Most towns and cities in India do not have proper waste management systems and untreated
solid waste is generally dumped in landfills or on the roadsides and the liquid wastes are
discharged into water bodies. Domestic wastes are mostly organic and on average are about
50% of the total wastes. It is estimated that each household produces not less than 200 kg of
organic solid wastes per year. This can be put to productive use rather than being thrown into
the bin from where it makes its way to over loaded landfills. These wastes can be considered
as a resource to produce manure for the soil using vermicomposting technology.
Vermicomposting for Rural Development
Large quantity of potential agro-industrial wastes and byproducts are thrown out as
wastes/under utilized by the local population since they are not aware of its importance. The
materials can be utilized profitably by vermicomposting, which is a low cost technology.
Unemployed rural population can do this, as part time/ full time profession if they are aware of
the technical know how to utilize the materials. Awareness about Vermiculture and
vermicomposting will motivate the rural people to start Vermicomposting units, which can fetch
regular income.
Revenue Generation through Vermiculture and Vermicomposting
Vermitechnology is popular because it is a simple methodology with low investment and does
not need sophisticated infrastructure. To process one ton of organic matter daily, it would
require about 1500 sq meters of space with 6 workers. It would produce about 70 tons of
earthworm casting annually (Gupta, 2003). Innovative, interested and talented rural people
can be successful entrepreneurs in vermicompost production and accruing profits will enhance
3. their life style and income. They will be able to spend time usefully by getting job opportunities
with the help of self-employment schemes.
Vermiculture technology
i) Earthworm for composting
Earthworms constitute more than 80 percent of soil invertebrate biomass. They feed on a
variety of organic waste materials and produce “Vermicastings”. It contains more
microorganisms, organic matter and inorganic minerals in the form that can be used by plants.
Nearly 10-15 percent primary production is channelized through earthworms. In absolutely
ideal conditions of comfort and ground up, moist food, the herd will recycle their own weight in
wastes every 24 hours (Gupta, 2003). Vermicomposting is an ideal and appropriate method
for disposal of nontoxic solid and liquid organic wastes.
ii) Selection of worms
There are about 3000 species of earthworms in the world. At present, earthworm fauna in the
Indian subcontinent comprises 509 species placed in 67 genera and 10 families. Earthworms
in ecological terms are classified into three groups depending on their ability to make burrows
and the intricacy of burrows:
Epigeic earthworms that cannot make burrows in the soil strata. They can only move
through the crevices of the surface
Endogeic are the subsoil dwellers found in deeper region of the soil and
Anecic earthworms found in the soil, which are not frequently disturbed.
Epigeic earthworm species efficiently enhances the rate of organic manure production through
biodegradation/mineralization compared to other species. The ideal epigeic category of
earthworm used for Vermicomposting are: Eudrillus eugeniae, Eisenia foetidae, Perionyx
excavatus, Lampito mauritii and Dravida willsil
iii) Culture maintenance
Epigeic earthworms remain active throughout the year under favourable conditions. Moisture
levels, temperature, food and space are essential for their survival and biomass production.
Temperature below 35°C and moisture level between 40 and 60 percent is ideal condition for
earthworm activity.
iv) Space for earthworm culture and size of pit
The convenient dimension such as 2m x 1m x 1 m has to be prepared.
v) Raw materials for Vermicomposting
Though earthworms can digest a diverse range of organic residues and yield rich
vermicompost, it is better to use pre-digested organic wastes for worms to act faster and
produce high quality compost. The pre-digested waste is an ideal medium for the worms to act
on. The pre-digested material will be converted into quality vermi-compost with in 30 days.
The composite organic wastes should be degraded using diluted fresh cow dung slurry, which
is to be sprinkled over the several layers of the heap. The heap has to be kept moist by
regular irrigation, and it will have to be turned two to three times at an interval of ten days.
vi) Preparation of vermibed

* Spraying of water is done on each layer
vii) Collection of earthworms
Earthworms can be collected from the fields by applying a simple technology. In a well-shaded
patch of the land where the earthworm castings are found, a small area of 1 m x 1 m should
be embarked. About 500 g jaggery and an equal quantity of fresh cow dung should be mixed
in 15 to 20 l of water and this diluted slurry should be sprinkled over the area. Wet pats of cow
dung is scattered over the area and a layer of moistened rice straw should be laid over it. The
whole area is covered with a jute sack. Regular watering should continue for a period of 20-25
days and care should be taken to avoid water stagnation. When the cover is removed one
can see 600-700 small worms that can be used for composting.
viii) Introduction of worms in to beds
The optimum number of worms to be introduced is 100/m length of the bed. Raw materials will
be spread again over the earthworms gently up to the level of 25 cm. In continuation, wet cow
dung with moisture will be covered over the level of 5 cm. Leaf dust of neem, Acorus calamus
rhizome dust and neem cake can be used in the management of enemies. After a period of 10
days the organic layering is mixed well gently without injuring the earthworm.
ix) Vermicomposting mechanism
Earthworm’s gut is an effective tubular bioreactor with raw materials (feed) entering from one
end and the product (castings) coming out through the other end. The temperature is
maintained by a novel temperature regulatory mechanism, accelerating the rates of
bioprocess and preventing enzyme inactivation caused by high temperature. Gizzard is
colloidal mill in which the feed is ground into particles smaller than 2m, giving thereby, an
increased surface area for microbial processing. Earthworm gut has nearly 73 percent of
gram-ve, facultative anerobic, Vibrio sp (an autochthonous micro flora) that are responsible for
the degradation of ingested food. Mucous produced by the glands in the anterior region of the
earthworm gut provides a favorable substrate for symbiotic microorganisms that decompose
complex organic compounds.
x) Harvesting of Vermicompost and storage
Watering has to be stopped 7 days prior to harvest so that worms settle at the bottom layer.
The layer will be obtained as black color. It is the indication that the conversion of the raw
materials and castings into compost. Matured compost, a fine loose granular mass will be
removed from pit, sieved, dried for 12 hours in shade and packed in fertilizer bags for storage.
This matured compost has rich nutrient value.
xi) Harvest of worm biomass
The worms and its cocoon are to be collected by sieving and used for subsequent
Vermicomposting.
Conclusion
