Assessment of molybdenum status in soil of Ratnagiri district

Abstract

The present investigation was undertaken to the assessment of molybdenum status in soil of Ratnagiri district, The Ninety surface soil samples (0-20 cm) were collected from the field of major crop in Ratnagiri district of Maharashtra. Ten soil samples from each tehsil from Mandangad, Dapoli, Khed, Chiplun, Guhagar, Ratnagiri, Sanghmeshwar, Lanja and Rajapur from Ratnagiri district were collected and analysed during the 2018-2019. The results indicated that, the physico-chemical properties of soils of Ratnagiri district found to be acidic to neutral in reaction. The electrical conductivity was recorded non saline nature of soil. The calcium carbonate was found in the range of 1.25 to 5.01 per cent. The organic carbon was found medium to high varied from 2.95 to 16.01 g kg-1. The available nitrogen was observed low to medium varied from 112.08 to 459.08 kg ha-1 indicates. The available phosphorus varied from 3.67 to 15.53 kg ha-1 indicates low available phosphorus status. The available potassium was recorded medium to high status. The nutrient index of available N was recorded in range from 1.20 to 1.70, available P 1.0 to 1.20 and available K, 2.60 to 3.00. Available molybdenum was recorded ranges from 0.01 to 0.64 mg kg-1 the soils of Ratnagiri district. The nutrient index of available molybdenum was recorded 1.88. However the 32.22 per cent soil samples were found deficient in available molybdenum.
