Collection and Characterization in Soils of Kvk Moradabad

Abstract

Study on the Collection and Characterization in Soils of KVK Moradabad 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 neutral in nature with very low EC and poor OC (%). Perusal of data also indicates that infiltration rate and hydraulic conductivity of KVK 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 52 % of KVK soil was favorable while ratio of remaining 48 % 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. Soil pH was strongly positively and negatively correlated with sand (r = 0.943), Infiltration rate (r = 0.899), hydraulic conductivity (0.889) and silt (r = -0.735) clay (r = -0.717). Soil pH negatively significant with water aggregate stability (r = -0.414). While soil pH was non-significant positive bulk density (r = 0.169) and negatively particle density (r = -0.236), porosity (r = -0.302). 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 below the threshold value (<3.34, 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.
