Worm Compost DIY:

What we require for worm compost.

• We need red earthworms. They are readily available in the university, any agricultural college.

• We need a bin, bedding is essential, vegetable peels, fruits peel, and any kitchen waste.

• Dry leaves, cardboard, newspaper, mature cow-dung.


We need a bin, and bedding is essential for composting. For bedding, you require cardboard, any shredded papers, dry leaves and some mature cow-dung because red earthworms love to eat cow dung and it should be moist always. Build this pile-up. And in coming 40 days, your compost is ready.

Vani Murthy shares, “Earthworms are the best friend of farmers, because the farmers land is rich because of earthworms, and it provides nutrition for the plants. And you get the black gold finally now you can harvest, grow your vegetables. Its Black Gold from waste.”

Aerobic Compost DIY

What we require for Aerobic Compost.

• Container

• Old newspaper

• Dry leaves

• Kitchen waste

• Accelerator, i.e. buttermilk, coding, panchagavya.

Add the accelerator buttermilk, sprinkle on it and mix it up. This is an aerobic process and you need oxygen. So you need to turn the pile once in a few days. Micro-organisms play a vital role in the process of Aerobic compost. Micro-organisms that could be anything from a kitchen or store. You can continue the same process the next day as well.

After 40 days, the compost is ready.
