Abstract:

An incubation experiment was conducted to study the release of micronutrients over a period of time upon addition of different substrates of organic matter to the soil. Three substrates of organic matter viz. farm yard manure (FYM), composts made from rice straw (RSC) and rubber leaves (RLC) were used for the study. In each pot 6 kg soils from the surface layer (0-30 cm) under a matured rubber plantation was taken. Substrates of the organic matter at the rate of 10 t ha -1 was added to each pot. The moisture content was maintained at sixty per cent (60%) water holding capacity of the soil at ambient temperature. A control was maintained throughout the experimental period. The experiment was conducted for three months and samples were collected after 7, 15, 30, 45, 60 and 90 days for analysis of various micronutrients. Results revealed variations in the rate of mineralization of the DTPA extractable micronutrients and HWS-B from different substrates of organic matter. Initial immobilizations of the DTPA-extractable micronutrient cations were observed irrespective of the substrate which was followed by gradual increase in their contents. With the incorporation of FYM, mineralization of micronutrients showed increasing trends from seven days onward and continued till the end of the experiment (90 days). Evidently addition of various substrates of organic matter resulted in building up of DTPA-extractable micronutrients and HWS-B.
