Abstract

Abstract: The effect of crushing degree （no crushing, coarse crushing, fine crushing） on the nutrients and maturity of radish compost was studied with waste radish as the main material. The results showed that the higher the degree of crushing was, the faster the composting started and the higher the temperature accumulated. At the end of composting, the content of the organic matter and total nutrients of the three treatments could meet the requirements of “Organic Fertilizer” （NY/T 525—2021）, and the organic matter content of the coarse crushing treatment was significantly higher than that of the other two treatments（P<0.05）. At the end of composting, the germination index of seeds treated with coarse crushing and fine crushing was 88.14% and 88.07%, respectively, meeting the requirements for maturity. Therefore, waste radishes could be successfully composted in both coarse and fine crushing conditions. Considering the treatment cost, it was recommended to use coarse crushing during radish composting.

Key words: vegetable waste, waste radish compost, crushing degree, nutrients, maturation
