The study area consists of the alluvial plains of Kothari River, which is the tributary of Banas andsituated in Eastern Rajasthan Upland. The area surrounded byAravalli hills andsituated between 25001’ and 25058’N latitude and 74001’ and 75028’ E longitudes. Twelve pedons were selected for the study of availablemacro and micronutrientswith the aim to sustain the better productivity and sustainability.Soils wereclassified ascoarseloamy, mixed hyperthermic Typic Haplusteptson higher elevations andfineloamy, mixed hyperthermic Typic Haplusteptson lower part of landform.Soils were analyzed for the status of available nitrogen, phosphorus, potassium, iron, manganese, zinc and copper content in vertical as well as in horizontal direction. Nitrogen, phosphorus andzinc content decreased in horizontal direction from higher elevation to lower elevation while ironand coppershowed a reverse trend.Almost all nutrient elements showed a decreasing pattern in vertical direction of the pedonsexcept copper.Soil properties viz. silt plus clay, organic carbon, pH, electrical conductivity and calcium carbonate together contributed 56, 63, 34, 50, 62 and 44 per cent to the availability of phosphorus, potassium, iron, manganese, zinc and copper, respectively.Soils on upper rolling plain with annual precipitation of less than 600 mmcan be utilizedwithout further deteriorationby planting erosion resistant crops like pulses or grasseswith economically important trees, like; mango, guava and Aonla.The soils of lower plains are relatively more fertile with high AWC, 700 to 800 mm annual precipitation and appropriate proportions of soil separates imparts the opportunityto the farmers to grow high value vegetable crops like okra, bottle gourd, ridge gourd or cowpea in Kharif whereas cabbage, cauliflower, brinjal, tomato, potato, French bean or pea in Rabi season.
