Among the crop residues used for preparation of compost, wheat straw (WS) + urea (1.5 - 4.5 per cent) + rock phosphate (RP) (6 - 12 per cent) + Sulphur (S) (1 to 3% through gypsum) and shredded cotton stalk (SCS) + urea (1.5 - 4.5%) + RP (6 – 12%) + S (1 to 3% through gypsum) were found equally beneficial in improving the quality of compost. The pH of compost rises initially and further drop at the maturity of compost. Composting with different sources of nutrient increased the concentration of total nitrogen, phosphorous, Citrate soluble and water soluble phosphorous, potassium, Sulphur and micronutrients concentration with the increased in the levels of gypsum and RP. | Integrated use of different sources of nutrients and microbes for improving quality of enrich compost
