Compost pit is prepared by allowing farm waste to rot in a mud tank. The waste is digested by earthworms. The mixture of cow dung, turmeric and neem is used to coat the floor and sides of the pit. Alternatively in place of neem leaves, the leaves of any other bitter plant can also be used to prepare this mixture.
Formulation: Cow dung, turmeric and neem is mixed together.
Ingredients: Cow dung, turmeric and neem (Azadirachta indica) leaves.

"The use of botanical pesticides offers eco-friendly pest control strategy to aid the agricultural practices. Among the various herbs, neem plant based insecticides has been the most accepted bio-pesticides, due to the presence of multiple limonoids in neem plant extracts and oil that not only provides a sustainable pest control mechanism but also prevents plant disease resistance, from various synthetic insecticides. Additionally, the efficacy of these pesticidal ingredients of neem can be augmented by encapsulating them in nanocarriers that facilitates in providing sustained and control release of phytochemicals along with site targeted delivery thus, increasing the productivity and yield of crops."
