Soil fertility status of coconut growing soils of Dakshina Kannada and Udupi district, Karnataka

Author(s): Avinash Kabber, KS Anil Kumar and K Govinda
Abstract: Soil fertility status of two pedons of coconut growing soils of coastal Karnataka ie. Beltangadi and Brahmavara of Dakshina Kannada and Udupi district, respectively were determined. The soils were acidic in reaction, non-saline in nature and low (subsurface soil) to high (surface soil) in organic carbon status. The clay distribution, cation exchange capacity and base saturation of the soils varied from 28.89 to 42.20 percent, 3.86 to 7.85 cmol (p+) kg-1 and 47.19 to 83.22 percent, respectively. The macronutrient status of the soil samples indicated that available nitrogen and potassium contents varied from low to medium and available phosphorus was found to be very low in both soil pedons. Available sulphur was deficient in Beltangadi soil pedon and it was varying from deficient to sufficient levels in different soil horizons of Brahmavara soil pedon. The exchangeable calcium and magnesium contents were low in both pedon locations. Among the DTPA extractable micronutrients, iron, manganese and zinc were adequate in most soil horizons. Copper was found to be sufficient in entire study area where as boron was found to be highly deficient.
