Falling leaves and branches in the schools, the communities and the organizations usually cause problems. Most used as garbage or few as compost for the waste treatment of falling leaves and branches. Traditional compositing commonly causes secondary pollution problems. This project developed a fast processing of composting-free technology to treat the falling leaves and branches with in 12 hours to produce a organic fertilizer. The theory of composting-free technology combines multi-functional treatment with physical, chemical and microbiological concepts. This development can instead of the traditional compositing for 2-3 months. This research also developed a serious of facilities to the treating formula to produce a legal organic fertilizer with meets the national standard. From pot experiments with two vegetables, the results indicated that the product can increase the crop production, and soil organic content, total N and available K, as well as to increase total N, K and Ca in the crop. The results suggest that the amount of composting-free products can be used up to 5-20 tons/ha in the field application, but can be used up to double amount for the surface mulching application in seedling, flower, tree fields.
The development of fast treatment is not only with economical and industrial potentials, but also with benefits of environmental protection. The technology can treat falling leaves and branches within one day for producing organic fertilizer and no waste water, as well as the reuse of the resource. The other in directed benefits is to save the life and space of garbage station and incinerator. This technology has many benefits and highly potential for the extension and application.
