Pressmud is an unavoidable waste generated from sugar industries. Pressmud is rich in many plant nutrients and it also has properties to ameliorate degraded soils. For this reason pressmud is believed to be of much use in agriculture. Many research works indicate that application of pressmud improves soil fertility, nutrient uptake and yeild of crops. Sulphitation pressmud can be used to amend the alkali soil whereas carbonation pressmud is useful to reclaim acidic soils. This review discusses about the prospects of pressmud utilisation in agriculture, especially with reference to soil conditioning and crop growth.
