2025/2/18/ · Composting: A Key Component of Manure Management. Composting is a vital aspect of sustainable manure management practices. It contains the natural decomposition of organic materials to create nutrient-rich soil amendments. By composting manure, farmers can reduce waste and produce valuable fertilizer for their crops.
2018/7/1/ · The intensification of the crop and livestock production has generated large amount of bio-waste, such as crop residue and animal manure. More importantly, the decoupling of the nutrient recycle between crop and livestock systems has led to environmental pollution in the air, soil and water (Bouwman et al., 2013; Gerber et al., 2013; Hou et al., 2016; Steinfeld et
2022/2/1/ · Static heap as a traditional composting method is the easiest way to convert manure to organic fertilizer with little equipment input.

2023/2/1/ · Water pollution has become a major concern in China (Tong et al., 2017).It is reported that over 60% of groundwater and 28% of surface waters are contaminated, falling into classes IV or V, unfit for human contact in China (Jia et al., 2019).Meanwhile, two-thirds of major coastal bays in China, representing a total area of 57,000 km 2, are classified as class IV or V
2024/11/1/ · The Life Cycle Assessment method was used to analyse and compare the environmental impacts of three systems of pig farming management: pig farming with pig manure fertilisation; pig farming using
2021/9/20/ · The co-existence of antibiotics and heavy metal (HM) is common in manure. However, existing strategies for improving antibiotic dissipation or HM immobilization during composting rarely consider their combined pollution. In this study, we used agricultural lime and a newly designed attapulgite-activ
2015/10/1/ · We formulated strategies for integrated manure management of pig and dairy cattle manure to reduce environmental impact throughout the manure management system by using a structured design
2019/1/1/ · A moisture content of around 55%–65% is commonly used for most composting material. Lei et al. [7] reported that when the water content was 65%, it was most beneficial for cow manure composting, whereas the recommended moisture content for pig manure composting is 66%. Too high moisture content will create anaerobic condition resulting in
2023/7/28/ · Furthermore, we found that heavy metal levels in WDG were lower than those in COM and PM. Therefore, adding WDG to livestock manures can improve the composting conditions and reduce environmental pollution. The incorporation of WDG into livestock manures resulted in an approximately 20% improvement in waste reduction rates after BSFL treatment.

The developed methodology can serve as an effective tool to reduce manure nutrient loss and mitigate the adverse effect on the rural environment. Abstract. The current trend towards larger pig farms increases their profitability but might harm animal welfare and the environment. More efficient pig manure management is a way to address this
