Microbial Necromass Amendments Rapid Soil Fertility Enhancement Experimental Database

In response to the short fallow cycle in intensive agriculture and the need for rapid soil fertility enhancement, this study explored a soil-maturation method by adjusting the physical and chemical properties of microbial residues to strengthen soil carbon sequestration capacity. Microbial-residue properties were regulated by controlling particle size (<0.05 mm vs 0.05–2 mm), material type (Embodiment 1 enriched in fungal residues vs Embodiment 2), and moisture status (air-dried vs moist), together with preliminary water management (30%, 50%, or no water addition). Two cinnamon soils with different textures were tested in incubation experiments, during which soil pH, electrical conductivity (EC), water-stable aggregate distribution, aggregate organic carbon content, and microbial community diversity were measured.
