Having livestock means having manure. Lots of it. One way to manage manure is to compost it. Composting can reduce the bulk of manure by about 50% and kill weed seeds and pathogens. The four ingredients for compost are materials containing carbon and nitrogen and air and water. There should be more carbon in the compost pile than nitrogen.
Jul 21, 2023 · As livestock and poultry farming expands in China, the generation of fecal waste has significantly increased. Inadequate waste management can contribute to environmental pollution. This study seeks to optimize small-scale composting systems to address the inefficiencies and the limited automation of traditional composting equipment. We redesigned the mixing blades and refined the ventilation
Jan 1, 2022 · In this chapter, we reviewed recent studies on the composting of organic manure as sustainable technology for integrated solid waste management. Although much progress has been made in understanding organic manure composting, there are still many unknown factors and mechanisms on the complex interactions between a substrate, physicochemical
The chemical composition of cow dung waste contains 14.5% organic matter,0.3%-0.45% nitrogen, 0.15%-0.25% phosphorus and 0.1%-0.15% potassium. It is a very valuable resource that can be used as fertilizer by planting industry. so cow dung fertilizer composition is enough for the plants.

Jan 23, 2019 · Aerobic composting is one of the most common for the treatment of solid organic wastes (Gavilanesterán et al. 2016; Rynk et al. 1992).Through composting, it could realize the harmlessness and resourcefulness for livestock manure, which was one of the technologies to realize the interface between livestock breeding and planting industry (Rasapoor et al. 2016; Yamada and Kawase 2006
Oct 1, 2023 · There is general recognition that the content of antibiotic residues in hen manure (HM) is higher than that in other livestock manure (Qian et al., 2018), and then damage level is particularly with HM application more severe. Subsequently, antibiotics prompt gene mutations in composting bacteria, and resulting in antibiotic resistance gene
When making compost, size of operation determines how the system will be managed. Very small scale composting can be done in a small plastic bucket. Large scale composting requires long rows of waste, turned by tractors using “windrowing” equipment. In between are piles can be managed with a manure fork or a bucket loader attached to a tractor.
