Effects of coffee pericarp and litter mulsching on soil microbiomes diversity and functions in a tropical coffee plantation, South China.

In recent decades, ecological cyclic cultivation models have attracted increasing attention, primarily because the decomposition of crop residues and litter enhances soil organic matter content, thereby altering the soil microenvironment and regulating the diversity and functions of soil microbial communities. However, the effects of different coffee waste mulching on the diversity of soil microbial communities and their functions are still unclear. Therefore, this study set up four kinds of covering treatments: uncovered coffee waste (C), covered coffee litter (L), covered coffee pericarp (P), and both covered coffee litter and pericarp (PL).

The impact of main root exudates on soil microbial community structure and function in coffee plantation soils.

Coffee is an important cash crop worldwide, but it has been plagued by serious continuous planting obstacles. Intercropping with could alleviate the continuous planting obstacle of coffee due to the diverse root secretions of . However, the mechanism of root secretion in alleviating coffee continuous planting obstacle is still unclear.
