Abstract :

In a study, soil physicochemical properties were studied in a paddy agroecosystem,NE India. Soil properties viz. texture, moisture, pH, bulk density, Organic Carbon,Available Nitrogen, Available Phosphorus and Available Potassium were studied at 0–10,10–20 and 20–30 cm depths at the study site ,investigation was carried out in kharifseason of 2015 in case of rainfedOryzasativaL. crop prior to transplantation after twenty annual cycles of rice–vegetables cropping sequence with annual application of inorganic fertilizers .Soil was found to be acidic with textural classification as sandy clay type. Organic Carbon was positively correlated with nutrients and clay and negatively with Bulk Density, sand and silt. Average storage value of nutrients upto 30 cm soil depth in the agroecosystem of Imphal reveal low status of Nitrogen and medium status of Phosphorus and Potassium indicating that continuous cycles of cultivation reduces the soil quality
