Effect of Gypsum on the Reclamation and Soil Chemical Properties in Sodic Soils of Raebareli District, Uttar Pradesh

Abstract

Soil sodicity is a significant environmental problem and has its negative impact on human health and agricultural sustainability. So, the current research was set out to investigate the effectiveness of gypsum as an amendment which improves the physical and chemical properties of soil and crop productivity. Experiment was conducted in a sodic soil at a farmer's field in Raebareli district of Uttar Pradesh, India. The field was irrigated with moderately saline but highly brackish water. The treatment of gypsum granule sizes (1-10 mm) were Control (No gypsum), Gypsum @ 100% GR in one splits and Gypsum @ 100% GR in two splits. In the present study an attempt was made to find out the improvement of micronutrients and chemical properties of soil in Gypsum amended soils. The effect of Gypsum application significantly improved the soil chemical properties by reducing the EC and pH.
