Assessment of molybdenum status in soil of Sindhudurg district of Maharashtra

Abstract

The present investigation was undertaken to the assessment of molybdenum status in soil of Sindhudurg district, The Eighty surface soil samples (0-20 cm) were collected from the field of major crop in Sindhudurg district of Maharashtra. Ten soil samples from each tehsil from Kudal, Sawantwadi, Kankavli, Devgad, Malwan, Vengurla, Dodamarg and Vaibhavwadi from Sindhudurg district were collected and analysed during the 2018-2019.The results indicated that, the physico-chemical properties of soils of Sindhudurg district found to be acidic to neutral in reaction. The electrical conductivity ranged between 0.04 to 0.55 dS m-1showing non saline nature of soil. The calcium carbonate was found in the range of 1.12 to 5.36 per cent. The organic carbon was found medium to high varied from 2.24 to 16.49g kg-1. The available nitrogen was observed low to medium varied from 134.70 to 417.26 kg ha-1 indicates. The available phosphorus varied from 3.08 to 14.25 kg ha-1 indicates low available phosphorus status. The available potassium was recorded medium to high status. The nutrient index of available nitrogen was recorded in range from 1.30 to 1.60, available P 1.0 to 1.10 and available K, 2.70 to 3.00 . Available molybdenum was recorded ranges from 0.01 to 0.62 mg kg-1the soils of Sindhudurg district. The nutrient index of available molybdenum was recorded 1.82. However the 38.35 per cent soil samples were found deficient in available molybdenum.
