Evaluation of Soil Fertility and Physico-chemical Properties of the Semi-arid Region of Eastern Jaipur Rajasthan, India

Abstract

An investigation on GPS-based soil chemical properties and fertility status of three different blocks and each block 3 villages (Chomu, Sanganer, Shahpura) of Jaipur district was undertaken during the year 2021-22. 27 soil samples were collected at three different depths (0-15, 15-30, 30-40 cm) and analysed. Different results were reported. The colour of soil samples changed with the depth. The pH of soils ranged between (pH 7.40 - 7.58). The electrical conductivity of the soil of the entire studied area was less than 1 dSm-1. The soil organic carbon status was low to medium, ranging from 0.10 to 0.25 % and organic matter ranged from 0.17 – 0.43%. The available nitrogen content of the entire studied area was low (166.37 to 192.75 kg ha-1). The available phosphorus and potassium content varied between 13.24 to 37.77 kg ha-1 and 146.88 to 232.32 kg ha-1. The available zinc, iron, copper and manganese of the soil ranged between 0.56 to 0.32 mg kg-1, 2.23 to 2.97 mg kg-1, 0.40 to 0.67 mg kg-1 and 2.17 to 2.95 mg kg-1. The fertility database would be very useful for extension functionaries, agricultural officers, scientists and above all the farmers for sustainable crop production.
