A recent study by the Kerala State Planning Board1 involving a comprehensive analysis of soils from all the Panchayats across all districts of the state shows acidity at a whopping 91% of the samples tested, with 54% of the samples testing for strong to extremely acid reaction (pH < 5.5). Thus P availability should have been seriously hampered in these soils, making it unavailable to crops. We now have a situation with 61% of the samples registering high (25–35 kg/ha) to extremely high (100 kg/ha) available P levels. The repeated application of manures based on N requirement could have caused P to accumulate in the soil. A practical approach would be to skip application of high analysis or complex fertilizers containing P in such soils. Also, periodical soil testing from recognized laboratories and soil test-based nutrient management are imperative to deal with the possible fallouts from excessive P accumulation in the soils of Kerala.
