Composted vs uncomposted organics

Article Abstract:

Atest was conducted to examine the major chemical characteristics of composted and uncomposted organic urban wastes and the effect of applying these wastes to a calcareous soil. Results showed that uncomposted materials have a high total organic carbon content which decreases with composting. Composted products have a higher concentration of heavy metalsdue to weight loss incurred in the process. When composts containing sewage sludge were added to the soil, yields were notably greater than the control, affirming its high fertilizing value in a short term period. Plants grown with uncomposted sludge showed higher levels of nitrogen and potassium.

Composting food waste on the farm

Article Abstract:

'On Farm Composting of Manure and Municipal Organic Wastes,' a study evaluating the feasibility of composting food wastes, focused on Parsell Farm in Rochester and Gray Mist Farm in Groveton. The farms represented diverse methods of farming and different composting goals. A reasonably priced open air window technology using existing farm equipment revealed that composting methods of farms can be used to process a number of wastes, including food, to produce a saleable product.
