Analysis of Macro and Micronutrients In some soils of Kutthalam Taluk of Nagapattlnam District in Tamil Nadu, India

摘要

Soil fertility Is one of the important factors controlling yields of the crops. Soil characterization in relation to evaluation of fertility status of the soils of an area or region is an important aspect in the context of sustainable agricultural production. Macronutrients (N,P,K) and micronutrients (Zn, Fe, Cu, Mn) are more important soil elements that control its fertility. Variation in nutrient supply is a natural phenomenon and some of them may be sufficient whereas others deficient. The stagnation in crop productivity cannot be boosted without judicious use of macro and micronutrient fertilizers to overcome existing deficiencies / imbalances. The study area covers 20 villages in Kutthalam Taluk of Nagapattlnam District in Tamilnadu. The soils of the area are characterized by light in texture, moderate to high pH and low to medium in organic matter content. Soil samples numbering of 100 samples were collected from all the 20 villages keeping in view of the physiographic characteristics in different cross sections of the area. The processed soil samples were analysed for physico-chemical properties using standard procedures.
