Before the green revolution, the problem of macro and micro nutrient deficiency was not an impediment in crop production in India due to subsistence farming with local crop varieties with low production potential. After the late sixties, green revolution changed the scenario of Indian agriculture. While aiming to achieve targeted yields, the fertility aspect of soil was ignored which led to many problems related to soil health, along with deficiencies of nutrient elements? Available data suggest annual nutrient gap of N, P and K of about 8 to10 millions tonnes in the Indian agriculture and 3.39 million tonnes in Maharashtra agriculture. Hence, assessment of macro and micronutrients status of Jalgaon district, Maharashtra state was carried out to delineated deficiency-sufficiency level of macronutrients and micronutrients for futuristic land use planning. A survey comprising of 450 farmers from 15 Tahsils of Jalgaon district of Maharashtra was carried out during the year 2019-2020. Representative surface soil samples were collected as per the method suggested by Yadav and Khanna (1965). They were analyzed for soil pH, electrical conductivity, organic carbon content, calcium carbonate content, available macro nutrients viz. N, P, K, S, and micronutrients like Fe, Zn, Cu and Mn . It was evidenced that soil pH of the Jalgaon district varied between 6.79 to 8.85 with an average of 7.74, while electrical conductivity was 0.14 to 2.38 dSm-1. Showing slightly acidic to alkaline and most of the soils are safe in total soluble salt content. Organic carbon content was very low to very high and soils are non calcareous to highly calcareous in nature. All soils found to be deficient in available nitrogen. The phosphorus was low to medium, however wide spread deficiency of P is noticed. The soils are rich in potassium and sulfur. Available Iron and zinc content was low to medium while copper and manganese content was sufficient. The data further suggest that soils are becoming saline and sodic in some part of Jalgaon district. The area of phosphorus and zinc deficiency is increasing. The lime induced iron chlorosis is becoming serious problem in irrigated and highly calcareous soil.
