Abstract
The present study was undertaken to investigate “Dynamics of Organic Residue Decomposition and Mineralization of Nutrients in Soil” during the year 2018-19 at Soil Science and Agricultural Chemistry Section, College of Agriculture, Nagpur. The experiment was laid out in completely randomized design (CRD) with nine treatments replicated thrice. The treatments were absolute control in T1, cowdung mixture in T2, paddy straw in T3, wheat straw in T4, sugarcane trash in T5, gliricidia lopping in T6, subabul leaves in T7, soybean stalks in T8, greengram stalks in T9. Subabul leaves mixture (T7) recorded maximum ammoniacal nitrogen and nitrate nitrogen throughout experimentation. Gliricidia lopping mixture ranked 1st by recording maximum P mineralization for 30, 60 (7.33 mg kg-1), 90 (7.55 mg kg-1) and 120 (7.45 mg kg-1) days of experimentation. Sulphur mineralization was also found highest in T6 by application of gliricidia lopping mixture during experimentation. Hence, for fast decomposition and nutrient mineralization legume residue is more efficient than cereal or other organic residue.
