COMPARATIVE SOIL PROFILE STUDY IN IRRIGATED AND NON-IRRIGATED AREA

Soil analysis is useful for cropping pattern so as to increase crop yield and to maintain long term productivity. The farmer's main objective is to maintain the productivity of his soil. An excessive use of fertilizer which is not utilized for crop production can pollute the environment. For this purpose, it is very important to consider as to what the crop requirement for various nutrients is and what their actual use is. In this study, components of soil such as pH, Salinity (EC), Nitrogen, Phosphorous and Potassium Fe, Cu, Mn, Zn were analyzed by different instruments like pH-meter, spectrophotometer, flame photometer and conductivity meter. The soil analysis was done for both Irrigated and Non-Irrigated area. The values of pH, Salinity (EC), Nitrogen, Phosphorous and Potassium, Fe, Cu, Mn, Zn were observed in moderate to slight increased or decreased range. The values for Irrigated areas were observed different than Non-Irrigated areas.
