Abstract:
Soil available Macro and micronutrient deficiency due to exhaustive cultivation is an emerging threat to modern agriculture. Delineating the distribution of micronutrients is an effective strategy for sustainable agriculture. A current study was performed to investigate the nutrient distribution of soils from the Hunsur block of Mysuru district, Karnataka. A total 110 soil samples were collected from the farmer’s field of Rangaiahnakoppalu, Cholenahalli, Kempanahalli, Gerasanahalli, Mydanahalli, Ayarahalli and Harohalli villages. The soil samples were analyzed for the physico-chemical properties (pH, Electrical conductivity and organic carbon), Available primary nutrients (Nitrogen, Phosphorous and Potassium) and available micronutrients (Iron, Manganese, Copper and Zinc) content in the soil. The data revealed that the 110 analyzed soil samples were moderately acidic to neutral in soil pH with normal electrical conductivity and low in organic carbon. Analysis of available primary nutrients revealed the low in available nitrogen, low to very high in available phosphorous and potassium. Further, analysis of available micronutrients showed that the all samples had deficient to excess in available iron, excess in manganese with few exceptions, sufficient to excess in copper and sufficient in zinc. The trend of various available macro and micro nutrient suggest imbalance of nutrient availability in soil which need immediate attenuation for managing soils on sustainable basis.
