Study of Soil Fertility Status in KVK Farm, Shahjahanpur, Uttar Pradesh, India

Abstract

A study entitled Study of soil fertility status in KVK farm Shahjahanpur, Uttar Pradesh, India was carried out during 2020-21. Soil Samples collected from different depths viz. 0-15 (Surface), 15-30 cm (Subsurface) were processed and analyzed for chemical properties. Soil pH, EC and OC ranged from 8.13-8.73, 0.20-0.28 and 0.41-0.76 at surface and all the samplers belongs to moderately alkaline to strongly alkaline range. Soils of KVK, Shahjahanpur classified based on pH, EC ( 1:2.5 soil: water ratio), and OC were low to medium, majority of soils falls under low EC and low to medium organic carbon, the available nitrogen of samples was in the range of 201.19 to 287.84 kg ha-1and were in low nutrient index range (1.38 NI), the available phosphorus of samples range between 16.34 to 21.67 kg ha-1for and falls in medium nutrient index range (2NI) while the available potassium of samples range between 357.54 to 484.98 kg ha-1 and falls in high nutrient index range (2.67 NI) where correlation acted positive in many of the cases. The soils of KVK, Shahjahanpur were categorized into low-medium-high (LMH) category based on available N, P and K concentrations. Ca/Mg ratio of the study area varied from 1.99-2.01 while Mg/K ratio varied from 1.20 to 2.26. Soils of study area were found in sufficient range for available Cu, Zn and Mn except of (Fe) Iron range found in marginal to sufficient. In these range of available nutrients wheat, rice, maize, fodder crops, pulses and some vegetables can be grown very well.
