Correlation of Physico-chemical Parameters of Soil and Soil Nutrient Index Status of Kollam District, Kerala, India

The present investigation was carried out at Sam Higginbottom University of Agriculture Technology and Sciences in the department Soil Science Agricultural Chemistry lab, India In this study, a total 27 soil samples were collected from nine different villages on November 2021 Kollam district Kerala, each village 3 analyzed for their Physico-chemical parameters by using standard laboratory techniques. According to Nutrient Index values, found be high Organic Carbon (2.59), Phosphorus (2.88), Calcium (3), Magnesium (2.55). low category Nitrogen (1). medium Potassium (1.88). critical limits nutrients results observed, 100% range (N) (64.5 – 181.32 kg ha-1), 92.5% Phosphorous (P) (9.40 56 89% (K) (100 403 (Ca) (3.2 18 Meq/100g), 78% (Mg) ( 0 7.60), Sulphur (S) (0.96 7.2). showed that improvement has one improving fertility quality practicing improved cropping patterns, decomposition organic wastes, mulching, tillage practices.
