Are resources, particularly dung and urine, available and are they sufficient to meet the sustainable agriculture requirements?
Animal dung is traditionally viewed in terms of N, P, K, and agriculture scientists argue that it is insufficient to replenish nutrients in lieu of chemical fertilizers. As a matter of fact, animal dung should be viewed as inoculants that kick-start microbial activity, to release nutrients in soil. Recycling of crop residues which have 85% of nutrients, coupled with inoculation with dung and urine as microbial inoculants (1gr of dung contains3 X1023 microbes) release the nutrients locked up in the soil, in addition to facilitating decomposition of crop residues applied to soil.
