COARSE ORGANIC FRACTION FROM COMPOST PLANTS : A DISCUSSION NOTE
When compost plants receive city waste (either mixed or segregated wet waste) and stabilize it in windrows (long heaps, turned weekly for aeration), about 40% by weight is lost as moisture reduction (from say 60% to 20% by weight). After screening, the yield of saleable compost is at best 15% which meets FCO particle size standards of 4mm and finer. That leaves 45% as a coarse organic fraction, which is currently considered as “rejects”.

CITY COMPOST FOR MOUNTAIN AGRICULTURE
Organic farming needs organic inputs. India’s soils, nurtured on home-waste-recycling practices that go back to Vedic times, averaged 2% organic carbon in the soil. That made the Green Revolution possible, as healthy soils responded well to added urea. Food wastes were first given to domestic animals and birds.

POLICIES TO ENCOURAGE USE OF CITY COMPOST IN INDIA
Composting of city wastes is now a legal requirement for all urban local bodies in India, but Central and State governments have yet to perceive it as a social good requiring official nurturing. The paper describes India’s current agricultural scenario, the proven benefits of Integrated Plant Nutrient Management (IPNM) and the use of city compost in drought-proofing crops and restoring degraded soils.

Water Saving Thru Vermicompost

South Africa is the country I work in. I started off as a solid waste consultant and used earthworms for that. I marketed household and industrial composters with earthworms as the composting agent. This led to farming and research on organic farming for 8 years and as a private consultant I found that water savings can be as high as 80% if the right methods are used. Here in South Africa the first sunny day is the start of the next drought, or it seems like that, and therefore we have to find ways of conserving water. Trials have shown that any chemical fertilizer used, increased the water requirement by up to 80%.

City Compost Chem Fert Works Wonders

1. India’s Green Revolution rescued our nation from famines and built up huge surplus stocks of food-grains, but at the cost of over 11.6 million hectares of low-productivity nutrient-depleted soils, ruined by unbalanced and excessive use of synthetic fertilizers and no organic manures or micronutrients. TERI has estimated the economic loss of these man-made barren lands at Rs 1 – 3 Billion, Annually, and attributes this to “increasing intensity of cultivation and inadequate and inappropriate application of fertilizers.”
