Problem soils possess undesirable physical properties like infiltration, water holding capacity, structure, texture, hydraulic conductivity and bulk density. These soils have soluble salts like chlorides and sulphates of Ca and Mg and Na in higher concentration. This leads to improper growth and development of crops resulting in low yield of crops. The soils possessing various constraints and management strategies are [...]
In this article we will discuss about the management of saline and sodic soils. Management of Saline Soils: Flooding and draining the flooded water after 3 to 4 days of flooding can leach down the soluble salts below root zone depth. Two to three such treatments can make the soil suitable for most crops. Leaching requirement (LR) is that fraction [...]
In this article we will discuss about:- 1. Stages of Reclamation of Saline and Alkali Soils 2. Process in Reclamation of Saline and Alkali Soils 3. Uses. Stages of Reclamation of Saline and Alkali Soils: 1. Leaching and Amending Stage: Saline soils are leached by ponding an appreciable depth of water with adequate drainage. The objectives and measures to be [...]
