Atomic Absorption Spectrophotometric Method for the Estimation of Micronutrients in Soil and their Effect on Plant Growth
Abstract
Micronutrients and macronutrients both are very essential for better growth, yield and quality in plants. Plants need them in traces only. Zinc, copper, iron, manganese, boron, Chlorine, molybdenum and nickel etc constitute main micronutrients that are needed for the better production of crops. Some plants grow very rapidly while some don’t show such rapid growths, which actually depends on the environment, soil quality, region, climate and the use of manure in the soil in which the plant is growing. The quantity and availability of mineral nutrients are altered by the use of high analysis inorganic fertilizers, manure, compost, mulch, and lime or sulphur and no use of organic manures and heavy uptake by high yielding. So a study was performed on measuring micronutrients and soil quality parameters viz., pH, Organic Carbon (OC), Conductivity (C), Potassium and Phosphorus in the vicinity of Jaipur and also the effect of them was studied on plant growth.
