Characterization and Evaluation of Vermicomposting Materials

Abstract The agricultural sector and growing food production needs rely on chemical fertilizers. This initially had positive effects production, but over the last decade, negative impacts of overuse have resulted in low crop productivity, increased pest disease infestation, soil degradation, consequent adverse environmental parameters. As one possibilities organic farming, we found vermicomposting as most sustainable practice. For assembly vermicomposting, mature cattle manure was utilized three different combinations with material earthworm inoculations (the household waste, grass clippings, mixture). experiment set up by random block design replications. Analyses qualitative parameters final product showed a pH reaction from neutral to slightly alkaline. nitrogen compound varied between 2.7% 2.9% carbon 45.59% 47.41%, showing C/N ratio 16.7‒16.67. potassium content 1.1% 1.2% K 2 O, phosphorus 0.3% 0.5%. gave quite good results waste manure, reaction, optimal ash almost similar NPK contents 16.7, satisfying levels trace elements heavy metal under limits. combination also best characterization humic fulvic acids vermicompost, ranging 1505 1778 cm −1 729 998 , respectively. These indicate that can increase quality product.
