Nitrification in no-tillage soil

No-tillage, as a conservation tillage method, significantly alters the soil nitrogen cycle process by reducing soil disturbance, improving soil aggregate structure, and increasing soil organic matter content .Nitrification, a crucial step in the soil nitrogen cycle, is the microbial-driven process of converting ammonium into nitrate , playing a vital role in plant nitrogen uptake and utilization . Ammonia-oxidizing archaea and ammonia-oxidizing bacteria are the primary microorganisms responsible for the ammonia oxidation process in nitrification.
