The Physicochemical Properties of Mandawar Block, Soil Dausa, Rajasthan, India

Analysed at the division of Soil Science and Agricultural Chemistry, Naini Agricultural Institute, Sam Higginbottom University of Agriculture Technology and Sciences. The soil texture of the experimental area varied from sandy loam to . In general, the top soil had higher sand fraction then the lower layers. The study revealed that the range of bulk density was varied from 1.32-1.47 Mg m-3, the bulk density was increased with increasing the depth as the compaction increases. The range of particle density was from 2.36 to 2.49 Mg m-3 and the pore space 37.77 to 44.17 %, respectively. The water retention capacity (WRC) of soil was ranged between 43.56 to 57.28. The pH of soils was in the range between pH 6.67 - 7.75. The electrical conductivity of soil of entire studied area were less than 1.00 dSm-1. The soil organic matter, ranges from 0.13 to 0.38 %. The available nitrogen content of entire studied area was low (162 to 310 kg ha-1). The available phosphorus and potassium content varied in between 15 to 52 kg ha-1 and 125 to 255 kg ha-1. The available zinc, copper, manganese and iron of experimental soil ranged between 0.30 to 0.82 mg kg-1, 0.36 to 1.32 mg kg-1, 1.50 to 6.04 mg kg-1 and 2.36 to 9.62 mg kg-1. The fertility data base would be very useful for extension functionaries, agricultural officers, scientist and above all the farmers for a sustainable crop production.
