A study was taken up to investigate the possibility of conversion of farm, city and industrial waste into enriched compost and to evaluate their nutritional quality. All the enriched compost treatments receiving rock phosphate and microbial inoculants showed superiority in respect of manorial value compared to other treatments with a low C/N ratio and increased total phosphorus. In the field experiment conducted under protective irrigation with ragi as test crop, all the enriched compost treatments were found to be superior to unenriched composts with respect to yield parameters. Among the compost treatments, enriched compost of pressmud and yeast sludge recorded higher nutrient value as compared to other compost treatments. The organic carbon and major nutrients and secondary nutrient contents of the soil after harvest of first crop increased due to addition of composts.
