Nitrate-induced hydroxyl radical releases deep soil organic carbon by opening the 'enzyme latch'under micro-aerobic conditions
Deep soils (defined here as soil layers> 1 m beneath the ground) contain a significant
amount of soil organic carbon (SOC) with a relatively slow turnover rate. In oxygen (O 2) limit …
