THURSDAY ? 10/06/2021

Process in Preparing Compost:

Collect the kitchen and garden waste etc... Take a composite bin or dig a pit that is around ? metre deep pits are dug and fill it

with the collected waste. Water is sprinkled to maintain moisture content followed by covering the mixture

with a layer of soil This is left as such for around 250-350 days and the waste gets converted into

microbial rich manure. This cycle is repeated after every 30 to 35 days". Once the compost is ready to be used, it will appear as a dark, crumbly material. It
