The Biochemistry of Organic Residues Controls Soil Nutrient Cycle and Energy Production

Fernanda Stremel

One of the most crucial elements affecting the breakdown of plant leftovers in soils is substrate composition. In a laboratory experiment, the relationship between organic residue biochemistry and rates of decomposition, soil aggregation, and soil humus composition was discovered. When seven distinct organic residues were added to a Webster soil and cultured for nine days with residues that had low phenolic acid contents, the aggregate mean weight diameters increased quickly and briefly. This rise was inversely connected with the soil’s carbohydrate content.
