Abstract:

Nutrients are essential for crop growth. Plants absorb nutrients from soil. The quantity and availability of these nutrients varies in various scales, between region, field or within field also. To manage this variation in soil nutrient status precision farming is a technology currently available for sustainable agriculture. This technology enables farm management on the basis of small-scale spatial variability of soil and crop parameters in the field. This study was carried out in Kuppam mandal of Andhra Pradesh. The objective of this study is to determine and map soil nutrient content, both major and micro nutrients variability in Kuppam mandal using geostatistical technique. The major and micronutrients were analyzed and mapped by Geostatistical techniques to quantify the level of spatial nutrient available and predict availability of nutrients at unsampled location also. Results indicated that 99.8% samples are low and 0.2 sample are medium in available Nitrogen, 13.4% are low, 19.7 % in medium and 66.7% are high in available Phosphorus, 47.1% samples low, 39.8% medium and 13.1 % samples are high in available Potassium, 78.9% sample sufficient and 21.1 % samples are deficient in Zinc, 63.6 % samples sufficient and 36.4% are deficient in Iron, 96.7 % sample sufficient and 3.3% samples deficient in Copper, 92.8% samples are sufficient and 7.2 % samples deficient in Manganese. The study revealed the potential and ability of geostatistical techniques in determining and mapping soil nutrient content of study area. Furthermore nutrient maps can be used for balance d fertilization and efficient fertilizer management.
