Mechanism of Straw Composting

The mechanism of straw composting is the process of mineralizing and humifying organic matter such as crop straw by a series of microorganisms. The process of composting was dominated by mineralization in the early stage and the humification process in the later stage. Composting can narrow the C / N ratio of organic matter, release nutrients from organic matter, and reduce the propagation of germs, eggs and weed seeds in compost materials. Therefore, the process of composting is not only the decomposition and resynthesis of organic matter, but also the process of innocuous treatment. The speed and direction of these processes are affected by compost composition, microorganisms and their environmental conditions. High Warm composting generally passes through the stages of fever, cooling and fertilizer retention.
