Production of compost for organic agriculture enriched with natural rocks
Abstract: Organic wastes such as animal manure, poultry manure and pith were used in 10 mixtures. Mixtures namber (1, 2, 3, 4, 5) composted of animal manure, poultry manure and pith at C/N ratio of about 30:1 for compost production using turn-over pile system. The mixtures (6, 7, 8, 9, and 10) were enriched by natural sources (rock phosphate, feldspar, sulfur, dolomite and bentonite). Composting process was extended for 12 weeks under aerobic conditions with proper moisture content. Temperature variations were monitored throghout the composting period. Mineralization rates of organic matter and transformation of nitrogen, C/N ratio during composting stages were also evaluated. Acid producing bacteria, total and fecal coliform bacteria, salmonella and shigella bacteria and nematoda were monitored.
results showed that the differed with the different mixtures and enrichment by natural sources. generally data showed that the best characteristics of compost were found to be in mixtures recived natural sources specially phosphate and potassium content
