BIOFERTILIZER PRODUCTION RATE – 300
KL/YEAR
[EIRI/EDPR/4751] J.C.: 2971US$, 2971INR
Fertilizers were welcomed with open arms, for they immediately increased the
yield of crops. But their recurrent use has done an irreparable damage to the
environment. Excess use of chemical fertilizers has led to the pollution and
contamination of the soil, has polluted water basins, destroyed micro-organisms
and friendly insects, making the crop more prone to diseases and reduced soil
fertility. More and more farmers are now looking for more eco-friendly options.
Bio-fertilizers have, to some extent provided an answer to the soil contamination.
Bio-fertilizers are eco-friendly fertilizers, which are being used to improve the
quality and fertility of the soil. Bio-fertilizers are made from biological wastes and
they do not contain any chemicals. They are beneficial to the soil, as they enrich
the soil with micro- organisms that help in producing organic nutrients, which in
turn help the soil to fight diseases. They therefore enrich the nutrient quality of
the soil. They also restore the depleted nutrients of the soil.
The main sources of bio-fertilizers are bacteria, fungi and cyanobacteria (blue-
green algae). Plants have a special relationship with bacteria and fungi. They
provide the plant with nutrition, resistance against diseases and the ability to
combat worst climatic conditions.
Bio-fertilizers are being viewed as the future of fertilizers, as they have the ability
to solve the problems of salinity of the soil, chemical-run offs from the fields. They,
therefore, ensure the well being of the nutrients present in the soil, therefore
making the soil more fertile with time.
