“…Wang et al [30], in a study, observed that overall, diverse crop residue quality generated distinct expressions of the structure and function of the soil microbial community. Similarly, Domínguez et al [31] reported that diversifying crop residues as an energy source for microbes will enhance enzymatic activities in the soil carried out by earthworms and finally augment the decomposition of organic matter. In addition to the quality and composition of crop residues, the organic matter decomposition is influenced by intrinsic soil conditions [32,33].…”

To monitor soil biological quality, it is of paramount importance to assess how chemically diverse organic residue amendments reciprocate to organic matter. The present incubation study aimed to evaluate the effect of organic residue amendments varying widely in their biochemical composition on the dynamics of soil enzymatic activity. The changes in the pattern of soil enzymatic activity have been monitored over a period of 63 days using a total of eleven different crop residues. The enzyme activity (dehydrogenase, fluorescein diacetate hydrolysis, acid phosphatase, alkaline phosphatase and phytase) in soils amended with chemically diverse organic residues were significantly higher as compared to the control. It was further observed that the enzymatic activities in Azadirachta indica, Avena sativa and Lens culinaris continued to be higher up to 28 days after their incorporation (DAI). Our study showed that plant residues varying in different cellulose and hemicellulose contents influenced the enzymatic activities as well as functional diversity of soil microbial communities.
