“…Microbial decomposers and remnants decomposition: Many studies have found that the addition of rotten microorganisms to the plant residues returning to the soil will improve the enzyme activity in the plant residues to varying degrees [ 19 ], and affect their decomposition rate. Due to the complexity of remnants composition and structure, however, the composite microbial decomposers are more stable and efficient in degradation of plant remnants.…”
