Assessment of Macro and Micronutrients in Soils from Panvel Area, Maharashtra, India
Journal Title: Universal Journal of Environmental Research and Technology - Year 2013, Vol 3, Issue 1
Abstract
Soil is a medium through which crops grow to perform the need of human for food and cloths. Agriculture refers to an art of hoist plants from the soils and is one of the most economical factors for human beings. In achieving better crop yield the farmers should be made aware about the status of soil constituents, chemistry of water available, nutrient supply to the crop, climatic conditions etc. Panvel is rice bowl of Kokan region of Maharashtra which is a staple food of majority of the people. Most of the rice producers are small farmers who lack resources and because of this the productivity of rice in this area is declining. This study has focused on the investigation of macro- and micronutrients in soils from Panvel area of Maharashtra. The soil samples collected from Poyange village near Panvel (Raigad district) in November 2006 - 2007. Ten representative locations were selected for the study and the analytical results were expected to be representative of the entire field. The different physical parameters and macro elements were analyzed in laboratory are pH, EC, Corg, P and K. The micro elements such as Cu, Zn, Fe, Mn were estimated by Atomic Absorption Spectroscopy while calcium and magnesium, carbonate, bicarbonate, chloride were estimated volumetrically. The observed values of microelements found to be the order of the Zn < Cu <Mn< Fe. Soil samples of the study area are found in rich in copper, manganese and iron while zinc is within range of normal soil. In this study soils show low pH values (< 7) indicating their acidic nature which can be counteracted by adding basic fertilizers. The low value of EC could be due to leaching of soluble salts due to high rain fall in this area. The study indicates that in all the soil samples natural manure and organic fertilizers are the best alternatives to augment Corg and micro-organism which will help increasing the rice productivity.
