Liming practice impact on post-harvest soil properties for maize-greengram cropping system in acid soil of Odisha

Abstract

A field experiment was conducted for two years by taking four crops to study the “Liming practice impact on post-harvest soil properties for Maize-Greengram cropping system in Acid soil of Odisha” in the village MV-13 in Malkangiri district of Odisha during both Kharif and Rabi in the year 2017 and 2018 .The soil was ameliorated with three different sources of liming materials (paper mill sludge, Stromatolyte and Calcium Silicate @ 0.2 LR) added with soil test based dose/nutrient expert with FYM. Results indicated the post-harvest soil properties indicated that The two years of cropping harvest of four crops made soil more acidic which was not received any lime application in different POPs. Integrated use of liming materials with FYM and fertilizers (STD/NE) maintaining the available macro and micro nutrients where was decline occurs in without liming practices. The continuous application of only fertilizers decline the nutrient status and creats acidity in post harvest soil. The application of liming practice with NE gives better results compare to the STD alone.
