Comparison of the quality of animal manure compost conventional methods with vermicompost animal manure from Lumbricus rubellus

Abstract

The research revealed that vermicomposting alters animal manure's physical and chemical properties more rapidly than conventional composting and produces more optimal macronutrient values, C-Organic, pH, and C/N. According to panellist observations, this is indicated by changes in the physical properties of livestock manure, including odour, texture, and colour. Chemically, the decomposition process is aided by earthworms yields higher-quality organic fertiliser than conventional composting techniques. According to research findings, the varieties of livestock manure produced the highest levels of various nutrients. The manure vermicompost with the highest total nitrogen content was cow manure, followed by goat and chicken manure. On the other hand, chicken manure vermicompost contained the highest concentration of available P, followed by goat and cow manure vermicompost. The vermicompost made from goat manure contained the most available K, followed by chicken and cow manure. Goat manure vermicompost had the highest Organic C content, followed by cow and chicken manure vermicompost. Regarding pH, goat manure vermicompost was the most acidic, followed by cow and chicken manure vermicompost. In addition, the chicken, goat, and cow manure C/N ratio values were the closest to the soil C/N ratio.
