Abstract

Specific soil conditions such as salinity/ alkalinity are considered to be the major global concern causing a serious threat to sustainability of a particular production system. Salt affected soils are mainly characterized by low organic matter content, poor soil fertility with respect to available macro and micronutrients. Therefore, judicious management of nutrients in addition to reclamation of these soils is considered to be the need of an hour for enhancing agricultural productivity while sustaining our resources. The crop response to added nutrients also varies considerably due to their diverse chemical composition and behavior in such soils which in turn affect the precipitation-dissolution reactions and adsorption-desorption kinetics and thereby affecting their availability to crops during growing season. This review paper attempts to review the efficient fertility management techniques in problematic soils particularly the salt affected soils under rice -wheat cropping system.
