Purpose Rice straw degradation in the soil is slow because of the high percentage of complex carbohydrates. Hence, farmers prefer to burn it in the agricultural field as a quicker alternative to the open burning of rice straw. Therefore, this study aims to characterize the bacteria from cow dung that can degrade rice straw. Method […]
Purpose Improper management of poultry feather (PF) leads to various environmental problems. Biodegradation of PF using Streptomyces sp. was initiated to recover N because PF is rich in keratin protein which is difficult to break down. Methods PF was collected, washed, chopped, and was transferred to plastic pots (200 ml each containing 30g PF). Streptomyces […]
Purpose This paper focuses on monitoring the behavior of five different types of waste and humus during composting to see the impact of the nature of the substrate on the process and the quality of mature compost. Method Green waste, coffee waste, household waste (Fraction of the household waste which having dimensions smaller than 8 […]
Purpose Recycling of nutrients from human excreta may offer an opportunity for smallholder farms to improve crop nutrition and soil fertility. However, when applying human urine as fertilizer, it may load natural and synthetic estrogens into the environment. To avoid pollution by endocrine disruptors, treatment methods before field application must be implemented. The present study […]
Purpose The objectives of this study were to assess the black soldier fly larvae (BSFL) composting potential and to analyze the quality of organic fertilizer produced for agricultural purposes. Method The waste biodegradation was determined by varying waste feed treatment (2, 2.5, 3.0, 3.5, to 4 kg) and control treatment of (2 kg) of heterogeneous […]
