Soil Health Assessment of Kvk Amroha

Abstract

Study on the soil health assessment of KVK Amroha was conducted during 2019-20.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 neutral in nature with very 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 in phosphorus and potassium. The Ca/Mg ratio of 80 % of farm soil was favorable while ratio of remaining 20 % soil was below favorable .Ratio of Mg/K was within favorable limits. Iron, manganese, copper and zinc were found in sufficient to more than sufficient range. A significant and negative correlation of pH with clay (r = - 0.208), porosity (r = -0.093), IR (r = -0.315), HC (r = -0.315) was found .Similarly OC was significantly and negatively correlated with sand (r = -0.56), porosity (r = - 0.28) but non significantly and negatively with BD(r=-0.355). Physical properties of the soils of study area were not ideal for growing crop satisfactorily. Most of the soils were susceptible to erosion as they have silt / clay ratio, clay ratio, modified clay ratio more than the threshold value (>0.4, 3.44 and 6.9, respectively) and critical level of soil organic matter and clay Moisture equivalent ratio below the threshold value (<3.34 and <1.5, respectively). 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.
