Answer:
1.To prepare compost, either a plastic or a concrete tank can be used. The size of the tank depends upon the availability of raw materials.
Collect the biomass and place it under the sun for about 8-12 days. Now chop it to the required size using the cutter.Prepare a cow dung slurry and sprinkle it on the heap for quick decomposition.Add a layer (2 – 3 inch) of soil or sand at the bottom of the tank.Now prepare fine bedding by adding partially decomposed cow dung, dried leaves and other biodegradable wastes collected from fields and kitchen. Distribute them evenly on the sand layer.Continue adding both the chopped bio-waste and partially decomposed cow dung layer-wise into the tank up to a depth of 0.5-1.0 ft.After adding all the bio-wastes, release the earthworm species over the mixture and cover the compost mixture with dry straw or gunny bags.Sprinkle water on a regular basis to maintain the moisture content of the compost.Cover the tank with a thatch roof to prevent the entry of ants, lizards, mouse, snakes, etc. and protect the compost from rainwater and direct sunshine.Have a frequent check to avoid the compost from overheating. Maintain proper moisture and temperature.

<span>Pesticide use is harmful to human agriculture because it

body and remains there. The chemical may still be present there when we are
going to the plant.</span>
