Seasonal Variations' Impact on Earthworms' Ability to Turn Biowaste into Vermicompost

One of the major reasons for decline in agriculture is the large-scale nutrient depletion through crop harvest and low level of

replenishments through inadequate nutrient use causing negative nutrient balance in the system.

Deterioration in the physical and biological properties of soil is further with holding crop yield.

At present, Indian agriculture is facing with a major problem of declining factor productivity. It

needed immediate remedial measures to ensure food security at present and in the coming years for

the long time. To achieve the goal of improving agricultural growth rate, we have to stream line

the practices of nutrient management, which require intensive forms of soil and crop

which will increase the efficiency of production inputs and protect the environment as

well as soil health. Moreover, during the past several decades' agriculture development

mainly focused on short term gains in productivity and profitability which has caused several

damage to soil fertility, health and environment. These changes motivated to

change in farming practices.

Organic farming seems to be a viable alternative because it enable the soil,

strengthen the natural resource base and sustains the biological production at different

levels. However, it requires large-scale organic manures and bio fertilizers. Acute

shortage of conventional bulky organic manures like compost, FYM, dung, oil cakes etc. also

necessitates the exploitation of other organic sources.

Weeds are plant which are unwanted to crop and other livings, they are found in abundant quantity

in crop fields, non-cropped areas, as well as in water bodies. These weeds are rich

in organic matter and contain handsome quantity of plant nutrients. Though, the much

attention has not been paid in order to harness the potential of these weeds and wastes

generation from agriculture farm as a source of organic manure. Obnoxious weed viz. Ipomea,

Waterhyacinth, Parthenium etc. are growing and spreading at alarming rate under non cropped and

aquatic ecology. They are nuisance at their growing place and have not any economic

importance in our livelihood.
