Results show a significant reduction in net global warming potential (GWP) when a functional unit of one metric ton of fresh solid dairy manure is managed through composting or biochar-composting compared to a reference system in which separated solid manure is stockpiled (Supporting Figure 10).
Jun 22, 2024 · and emphasize the treatment of livestock and poultry manure from large-scale farms [24– 26]. Consequently, there is a growing trend towards utilizing efficient composting equip-ment for fermenting cattle and sheep manure [27,28]. During the composting process, differences in conditions can lead to significant changes in compost materials

Composting provides a way to process manure in a way that reduces volume, creates a stable organic fertilizer, and potentially destroys pathogens and weed seeds in manure. Livestock and poultry manure composts are an excellent source of slow-release plant nutrients. They also provide organic matter
Dec 1, 2022 · In this study, we used both chicken and pig manure as the main composting substrates and applied biochar to construct multiple industrial-scale composting systems for processing. By the means of high-throughput sequencing and quantitative PCR technologies, we characterized the dynamic changes of the bacterial community, ARGs and MGEs
With aerated composting, turning the pile is unnecessary; in fact, turning the pile impedes the composting process. All of our composting systems convert raw organic residuals into stable compost in roughly 60 days, yielding a nutrient-rich product that is effectively free of pathogens, parasites and weed seeds.
Mar 1, 2024 · Platanus leaves and livestock manure from Huazhong Agricultural University were carefully chosen as the primary constituents for the composting process. The common physicochemical properties of those raw materials were provided in Table S1. Prior to composting, the platanus leaves were meticulously ground to a size of 10–20 mm using a grinder.
Manure management: Implications for greenhouse gas emissions. Jun 23, 2011 · 1. Scope and introduction. There is much interest in understanding effects of manure management on direct and indirect source of greenhouse gas (GHG) emissions, as manures contain substantial quantities of N, much of which is in inorganic forms (Anon., 2010), C (e.g., Paul et al., 1993, Møller et al., 2004a) and
Oct 25, 2020 · Soil health is the capacity of the soil to provide an environment for optimum growth and development of plants, while also ensuring the health of animals and humans. Animal manure has been used for centuries as a source of nutrients in agriculture. However, many other soil properties that contribute to soil health are affected when manure is applied. Bulk density, aggregate stability

The decrease in volume reduces hauling costs. Wiederholt et al., (2009) conducted a case study that compared the energy required of a 180-head feedlot operation that applied raw manure and composted manure to agricultural fields. They concluded that composting and applying livestock compost is more energy efficient than hauling raw manure.
