Study of Macro and Micro Nutrient Availability in Soils of Shamli Kvk

Abstract

Study of Macro and Micro nutrient availability in soils of Shamli KVK was conducted during 2020-21. Soil samples were collected and brought to the laboratory of Department of soil Science and Agricultural Chemistry, SVPUAT, Meerut. Results of study indicate that the texture of farm soil was sandy loam. Soils are slightly alkaline to moderately alkalin in nature with low EC and poor OC (%). Perusal of data also indicates that infiltration rate and hydraulic conductivity of farm soil is moderate to moderately rapid with low water stable aggregate. Soils are low in available nitrogen and medium to high in phosphorus and potassium. The Ca/Mg ratio of 100 % of farm soil was favorable. Ratio of Mg/K was within favorable limits. Iron, manganese, copper and zinc were found in sufficient to more than sufficient range. Soil pH was significantly and positively correlated with manganese (r = 0.226), non-significantly and negatively with electrical conductivity (r= -0.037), positively with nitrogen (r =0.220), phosphorus (r =0.310), negatively with potassium (r = -0.251), and with organic Carbon (r =0.190), Cu (r =0.362), Fe (r =-0.110), Zn (r = -0.096), and significantly and positively with SAR (r =0.042) and non-significantly positive relations with ESP (r=0.045). A positively correlated pH with sand (r = 0.247), silt (r = 0.290), and negatively correlated with clay (r = -0.217), bulk density (r = -0.218), particle density (r = -0.064), porosity (r = -0.064), infiltration rate (r = -0.008), hydraulic conductivity (r = -0.009), and water stable aggregate (r = -0.163). Physical properties of the soils of study area were not ideal for growing crop satisfactorily. Based on the study of characterization of soil and fertility status, the soils of study area were found poor in soil health with several limitations and needs special managements to improve soil health and crop production
