Organic Fertiliser Decomposition Rate against Soil Nutrients

Abstract

The land is a non-renewable resource if seen from the potential improvements caused by environmental damage. Damage to the land is caused by the degradation of soil organic matter. Formulation of organic fertiliser in planting media is an alternative in agricultural cultivation on marginal land. The study aims to obtain organic fertiliser formulations used in agricultural cultivation. The study was arranged using a completely randomized design with treatment: M1 (25% Biochar, 25% vermicompost, 30% chicken manure, 20% compost), M2 (25% Biochar, 25% vermicompost, 20% chicken manure, 30% compost) , M3 (25% Biochar, 25% Vermicelli, 30% Cow manure, 20% Compost), M4 (25% Biochar, 25% Vermicelli, 20% Cow manure, 30% Compost), M5 (25% Biochar, 25 % vermicompost, 30% Goat manure, 20% Compost), and M6 (25% Biochar, 25% vermicompost, 20% Goat manure, 30% Compost). Statistical test results obtained on the M3 treatment provide the availability of nutrients (Organic-C, Total N, Total P and Total K) which are significantly different and the highest yield compared to other treatments. Whereas the results of FT-IR analysis found that the treated media had experienced decomposition of organic matter so that organic elements were produced which could support the availability of plant nutrients.
