Title: Composting Impact on Banana Pseudostem and Chicken Manure
Abstract: Compost comparison tests were conducted using banana pseudostem and chicken manure as substrate materials,with different C/N ratios of 15.2,21.5,25.5,31.8,41.5.The variance of the compost pile temperature,moisture,pH,EC,total carbon,total nitrogen,C/N ratio and nutrients availability was studied quantitatively during the process of composting.Results showed that when the original C/N ratio was in the range of 20~40,aerobic composting was successful.When the C/N ratio was below 15.2,though the pile temperature increased rapidly,the high temperature lasted short time.In addition,high pH,high soluble salt concentration,poor organic matter and total nutrient,and increasing cost of composting were unfavorable to the composting process.When C/N ratio was over 41.5,the pile temperature increased slowly and high temperature lasted long,but pile moisture percentage was too high.In summary,the appropriate C/N ratio range for composting was 20~30,and the optimum value was 25.5.Composting time was 27 days,and the corresponding C/N was 18.
