Crop production in saline and sodic soils is neither feasible nor economically profitable. This is due
to the specific soil and water related constraints of these soils. Saline soils have excessive amounts of
soluble salts which adversely affect the growth of most crop plants. Similarly, the high
exchangeable sodium present in sodic soils is injurious to most crop plants. Traditionally, leaching
with good quality water is recommended to make the saline soils suitable for crop production.
Sodic soil reclamation requires the removal of toxic exchangeable sodium by calcium ions in the
root zone. This is mainly achieved by gypsum application. However, the efficacy of both the
management practices is limited by the scarcity of good quality water and gradually diminishing
gypsum supply. This scenario has necessitated the development of alternative technologies for the
sustainable management of these resource poor and challenging environments. The article
highlights the agroforestry techniques developed by the CSSRI, Karnal which can enable the
economic exploitation of such marginal lands.
