The current review reports the importance and significance of cattle solid waste in vermicomposting technology concerning biowaste pollution in the environment. Needy increasing population evokes livestock production resulting in the massive generation of livestock wastes, especially cattle dung. Improper disposal and handling of biowastes originating from agriculture, industries, forests, rural and urban areas lead to nutrient loss, environmental pollution and health risks. Among the organic waste disposal methods available, vermicomposting is regarded as an environmentally friendly technology for bioconversion of agricultural, industrial, rural and urban generated organic solid wastes which are serving as reservoirs of environmental pollution. In vermicomposting of organic wastes, cattle dung plays a central role in mineralization, nutrient recovery, earthworm and microbial activity leading to vermifertilizer production. Even though the vermicomposting studies use cattle dung invariably as an amendment material, its importance has not been reviewed to highlight its central role. Hence, the present review mainly emphasizes the key role played by cattle dung in vermicomposting. Vermiconversion of cattle dung alone and in combination with other biowaste materials of environmental concern, mechanisms involved and benefits of vermicompost in sustainable agriculture are the major objectives addressed in the present review. The analysis reveals that cattle dung is indispensable amendment material for vermicomposting technology to ensure agricultural and environmental sustainability by reducing pollution risks associated with biowastes on one hand, and nutrient-rich benign vermifertilizer production on the other hand.
本综述报告重点介绍了牛粪在蚯蚓堆肥技术中的重要性和意义，以解决环境中生物废弃物污染问题。不断增长的人口需求促使畜牧业生产大量产生牲畜粪便等牲畜废弃物。如果对农业、工业、林业、农村和城市地区产生的生物废物处理不当或处置不当，会导致养分流失、环境污染和健康风险。在现有的有机废物处理方法中，蚯蚓堆肥被认为是一种环保技术，可将农业、工业、农村和城市产生的有机固体废物进行生物转化，这些固体废物是环境污染的储存库。在有机废物的蚯蚓堆肥中，牛粪在矿化、养分回收、蚯蚓和微生物活性方面起着核心作用，从而生产出蚯蚓肥料。尽管蚯蚓堆肥研究通常将牛粪用作改良材料，但尚未对其重要性进行综述，以突出其核心作用。因此，本综述主要强调了牛粪在蚯蚓堆肥中的关键作用。本综述主要探讨了牛粪在蚯蚓堆肥中的作用，包括单独和与其他环境关注的生物废物材料结合的蚓转化、涉及的机制以及蚯蚓堆肥在可持续农业中的好处。分析表明，牛粪是蚯蚓堆肥技术不可或缺的改良材料，一方面可以降低与生物废物相关的污染风险，另一方面可以生产养分丰富的良性蚯蚓肥料，从而确保农业和环境的可持续性。
