Study of Humification Dynamics of Organic Residues on Vermicomposting Process

摘要

The work aims the study of humification of three organic residues (cattle manure,orange pomace and filter cake) submitted to vermicomposting during six months.Some parameters were studied such as pH,temperature,total carbon,total nitrogen and C/N ratio.The data showed typical behavior of the composting process including mesophilic,thermophilic,cooling and maturation phases,the important preliminary results on the dynamics of the process of vermicomposting.
