Summary:

As for micro nutrients, the phosphorus content (30.9 kg/ha) and available potash (352 kg/ha) is higher in the accumulated soil. Samples also had high metal content - Iron (357 ppm), manganese (119 ppm) and copper (5.09 ppm). It need to be mixed with preexisting soil which are lateritic and of sandy loam texture,” said Shinoj Subramanian, scientist-in-charge, KVK-Ernakulam.The pH of the soil samples is in the range of 5.9 - 6.0, which indicates slightly acidic nature. But the soil, once it dries out, cannot be used directly since it gets hard and non-porous. Alternatively, addition of cocopeat or river sand reduces the hardening of the silt.Organic carbon, which determines the nitrogen level in the accumulated soils ranges from 1.85 to 1.9% which is high..
