Pastures serve as the primary source of grass and forage plants for grazing livestock, requiring adequate nutrient input to sustain growth and soil fertility. Slurry from the livestock industry is widely utilized as a sustainable and cost-effective alternative to chemical fertilizers. Microorganisms within the slurry-pasture system are essential for breaking down organic matter, facilitating nutrient cycling, and improving soil health. However, mismanagement or inefficient microbial decomposition can lead to significant issues, such as nutrient leaching into water bodies, causing eutrophication, antimicrobial resistance, and reduced nutrient availability in pastures, which, in turn, may negatively impact livestock productivity. Thus, this paper investigates the composition and benefits of livestock slurry in pasture management, highlights microbial roles in nutrient cycling, and evaluates regulatory frameworks in Ireland and Europe. Additionally, it examines the environmental risks associated with improper slurry application, providing insights to support sustainable management practices.
牧场是放牧牲畜的主要青草和饲料植物来源，需要充足的养分投入来维持生长和土壤肥力。畜牧业产生的粪便被广泛用作化肥的可持续且经济高效的替代品。粪便-牧场系统中的微生物对于分解有机物、促进养分循环和改善土壤健康至关重要。然而，管理不善或微生物分解效率低下会导致重大问题，例如养分渗入水体导致富营养化、产生抗微生物耐药性以及牧场养分有效性降低，进而可能对牲畜生产力产生负面影响。因此，本文研究了牲畜粪便在牧场管理中的组成和益处，强调了微生物在养分循环中的作用，并评估了爱尔兰和欧洲的监管框架。此外，还研究了不当施用粪便带来的环境风险，为支持可持续管理实践提供见解。
