Abstract
The soils of various fields of Agricultural Research Station, Ummedganj-Kota were collected and analyzed for the physical properties (soil colour, texture, bulk density, particle density, porosity and water holding capacity), physico-chemical properties (pH, EC and organic carbon) and available macro and micronutrients (N, P, K, Fe, Cu, Zn, and Mn). Soil maps prepared with the help of GIS software using geo-statistical analysis. Majority of the soils were found clay loam to clayey in texture with highest variability in sand and clay content, whereas, minimum in case of silt. The BD ranged from 1.25 to 1.57 Mg m-3 with a mean value of 1.43 Mg m-3, PD of the soils ranged from 2.57 to 2.71 Mg m-3 with mean value of 2.68 Mg m-3 and the porosity of the soils ranged from 41.42 to 51.92% with mean value of 46.42%.WHC of the soils ranged from 35.11-52.46% with mean value of 44.31% and soil colour varied from brown, dark brown, dark gray, very dark gray and black.
The soils were neutral to alkaline in soil reaction (pH) and most of the soil EC <1 dS m-1, means soluble salt content in safe limit. The organic carbon content ranged from 0.30 to 0.79% with a mean value of 0.50%, in general, the organic carbon status of soils was under low (18.33%) to moderate (76.00%) categories. The available nitrogen of the soils ranged from 142.90 to 380.53 kg ha-1 with a mean value of 246.76 kg ha-1, thus, overall the available nitrogen status was low in these soils (77.33%). The available P of the soils ranged from 4.60 to 42.02 kg ha-1 with a mean value 20.09 kg ha-1, available P status of soils falls under moderate (47.00%) and moderately high (23.66%) categories.
