  • 摘要:The aim of this study is to evaluate effect of cane molasses on total nitrogen and C/N ratio of municipal wastes compost and cattle manure. Treatments included different amounts of molasses with municipal decomposable wastes and cattle manure that were added to organic wastes in 2 and 4 weeks after composting start (first and second stages). Each of treatments with 20 kg fresh organic wastes (decomposable municipal wastes and manure) in three replicates as a completely randomized design was done. After 50 days, a 100 g sample of every treatment was taken to measure total nitrogen, organic carbon, C/N ratio, EC and pH in 1:6 dry organic matter /water. Results indicated that the molasses held nitrogen in compost caused to reduce C/N ratio. The effect of molasses on total nitrogen of manure treatments is more than municipal wastes. Total nitrogen of 4% molasses-manure treatment at the second stage increased 4.6 times than its control; while this was only 1.43 times for 4% molasses-municipal wastes treatment at the same stage than municipal wastes-control treatment.
