- Abstract
This study aimed to compare the macronutrients of earthworm manure derived from degradation of paper and organic waste. The two different species of earthworms used were Pheretima peguana (PP) and Eudrilus eugeniae (Common name: African Night Crawler) (AF). The vermicompost experiment was prepared by filling loose soil in two containers to 6 inch height (the weight of 13 kg), then sprinkling water to adjust the moisture content to about 70-80%. Each species of earthworm was then mixed with the soil for 0.2 kg each tank. Food for earthworms were prepared by mixing crushed fresh garbage and dry leaves (mixing ratio of 1:1 by weight) and paper waste and sprinkling with effective microorganisms (EM) for 50 ml/L. This combination was then applied to the fermenting containers for about 2 cm thick (the weight of 1 kg) and kept for 2 months. This experimental research and analysis was carried out at a laboratory scale. From the experiment of vermicomposting from degradation of paper and organic waste using two different species, the results showed that AF produced higher macronutrient content with total nitrogen, available phosphorus, available potassium, organic matter, cation exchange capacity (CEC) and electrical conductivity (EC) at the highest levels of 0.440%, 0.030%, 0.352%, 11.770%, 16.277 Cmol/kg and 1.200 dS/m, respectively. The earthworm AF species are large in size, having high capacity to degrade organic waste. The organic waste used in this study was garbage with a variety of vegetables, food and dry leaves, which was rich in nutrient elements. The pH of all four earthworm’s manure varied from 7.347 to 7.667. Results from this study show that the earthworm species AF which has large body, could degrade organic waste well. In addition, the organic waste containing a variety of vegetable waste, food waste and dry leaves, which are sources of nutrients so that containing the nutrient elements in large quantities.
