Present study aimed to evaluate the vermicomposting of lignocellulosic wastes employing Eisenia fetida earthworms. The study examined the effectiveness of vermicomposting for 105 days by mixing lignocellulosic waste (LW) with cattle manure (CM) in five different proportions. Results revealed that TOC and C/N ratio decreased gradually till end and in vermicomposts varied between 268-320 g/kg and 12.26-16.85, respectively. Nutrient content (NPK) in the vermicomposts increased with time in all the mixtures. Heavy metals' content also increased in vermicomposts and benefit ratio for heavy metals ranged between 0.06 and 5.1. Increase in earthworm biomass (22.38-39.64 g) and reproduction (21.27-31.60 hatchlings/worm) was also satisfactory in all the waste mixtures. Based on results, it can be inferred that lignocellulosic waste can successfully be converted into good quality manure employing earthworms.
本研究旨在利用赤子爱胜蚓对木质纤维素废物进行堆肥。该研究通过将木质纤维素废物 (LW) 与牛粪 (CM) 以五种不同比例混合，对 105 天的堆肥效果进行了检查。结果表明，TOC 和 C/N 比在堆肥过程中逐渐降低，最终分别在 268-320g/kg 和 12.26-16.85 之间变化。所有混合物中的养分含量（NPK）随时间的推移而增加。重金属含量也在堆肥中增加，重金属的效益比在 0.06 到 5.1 之间。在所有废物混合物中，蚯蚓生物量（22.38-39.64g）和繁殖（21.27-31.60 只/条）的增加也令人满意。根据结果可以推断，木质纤维素废物可以成功地利用蚯蚓转化为优质肥料。
