Long-Term Organic Fertilization Drives Soil Organic Carbon Accumulation in Black Soil Through Microbial Necromass Carbon and CAZyme-Mediated Carbon Turnover
Long-term organic inputs increase soil organic carbon (SOC) in black soil; however, it remains uncertain if straw and manure enhance SOC via separate microbial necromass carbon (MNC) routes. Therefore, a 12-year field experiment was conducted to explore this mechanism. Treatments included inorganic fertilizer, partial...
