Physico-chemical characteristics with enzyme activity of topsoil for farmlands management of Ajmer, Rajasthan

Soil health is related to characteristics of soil such as fertility. The purpose of this study was to estimate the fertilization status of Ajmer farmland on different soil parameters. The soil fertilization status were influenced by soil parameters, the following parameters: sand, silt, clay content, texture, calcium carbonate, cation exchange capacity, pH, EC, OC, OM, N, P, K, Zn, Fe, Cu, Mn, B, enzyme activity of dehydrogenase, acid phosphatase and alkaline phosphatase were identified. The results were showed that soil organic carbon, nitrogen and potassium were analyzed in low range 23%, 25% and 22% respectively, in the farmland soil of Ajmer district. For 49% FLS, low concentration of iron were examined. In farmland soil, sufficient range of zinc, copper and manganese were observed but iron concentration found low for 74.21% farmland. Mean dehydrogenase activity 9.351 p Kat g-1 was assessed for FLS of Ajmer. With the helping of SFM model, imbalanced nutrient level was assessed and suggested micro-organisms to balanced soil nutrients. Soil nutrients were vital factors affecting crop production and soil fertility. These new soil information is needed to provide useful additional knowledge to policy makers, farmers and other scientist about soil like enzyme activity, nutrient concentration and soil ecology of Ajmer.
