MICRONUTRIENTS STATUS IN SOIL UNDER COMMAND AREA OF UPPER KUNDALIKA PROJECT BEED DISTRICT (MAHARASHTRA)

Abstract :

An increase in cropping intensity coupled with shift from traditional varieties to that of nutrient demanding fertilizer responsive high yielding varieties of field crops comprising cereals, pulses, oilseed, cotton and long duration crops like Sugarcane and fruit crops has led to the large scale mining of nutrient from soil. This is particularly true in case of the situations where these crops are grown without adequate and balanced fertilization thereby causing depletion and wide spread deficiencies of most of the major and micronutrients. The physico-chemical characteristics like pH, EC, content of organic carbon and calcium carbonate are important as these affect on availability of nutrients in soil and thereby on crop growth and production. The soil must supply the nutrients that are essential for plant growth and necessary component of human and animal food for sustainable agriculture. The availability of nutrients is highly influenced by pH of soil. Organic matter is the indicator of organic carbon status in soil. Organic matter acts as buffering agent and after decomposing produce organic acids and CO2 which helps to dissolve the minerals in soil. To know the present status of soil in the study area, 25 sampling stations were selected from irrigated farmland in winter season. The important physico-chemical properties and micronutrients status of soil were evaluated during present investigation such as pH, EC, CaCO3, OC, and micronutrient like Fe, Cu, Mn and Zn etc. The study revealed that there was depletion in organic carbon, Iron & Zinc. The deficiencies of these nutrients affect on yield of crop
