Research progress in the use of turf cutting litter

There is a large amount of turf cutting litter produced in China every year. The processing and utilization of lawn grass can play a role in mitigating the shortage of energy, feed, fertilizer, and protein resources. Therefore, the way to use turf cutting litter has become a significant research subject. Four methods of turf cutting litter usage including energy regeneration, feed processing, fertilizer transformed, and deep processing were analysed. The research progress of turf grass production in energy production, feeding livestock, composting, and processing leaf protein was introduced in detail. It was pointed out that different treatment methods should be adopted for grasses and legumes, and the input and output of each processing mode should also be further quantified. Further, conclusions and suggestions were made for future research in the methods for turf cutting litter usage.
