The people in the rural areas of India, collect the trash from the cattle sheds, kitchens, houses, etc. Kitchen waste consisting of charcoal and ash from the stoves, wasted food / vegetables etc. and majority of the compost consisting of wasted biomass used as feed, dung and partly urine soaked with biomass and dung. Broken Pottery shards / roof tiles also found in this trash. All the trash collected day to day and dumped in a in a pit over a period of one year, gets composted very well, is also called Farm Yard Manure (FYM). The inoculation of charcoal with soil microbes is very much possible in this situation, which enhances the property of the charcoal. Similarly the pottery shards property in the compost is enhanced. This is one of the ways charcoal as biochar is contributed to the soils in India traditionally. This is a cultural and traditional practice existing in majority of the parts of India. In most cases the livestock is kept close to the residential areas in many parts of India, for many reasons.

Holi / Sankranti 1 2 / are the major festivals, intentionally in some parts of India, large quantities of biomass is burnt and large amounts of charcoal and ash is created, which also finally reaches the soils.

For almost all types of events / occasions pottery items are ordered as part of the rituals. In many parts of India, from birth to death pottery is used. So, many pottery shards are regularly contributed to the rural trash, which finds its way into the soils.

Note: Compost pits located away from residential areas may not have charcoal in them.
