%X The effects of N inputs,including N fertilizer applications and atmospheric N depositions, on CH 4 oxidation by soils were determined by CH 4 oxidizing bacteria, N inputs and soil factors. These effects were inhibitory or stimulative, but inhibition was more popular than stimulation, and the inhibition of NH 4 + was more popular than that of NO 3 -. Wealthy experiments in different soils and climate regions are required to monitor and evaluate how N inputs influence CH 4 oxidation in soils. Generally, CH 4 oxidation in soils following N inputs showed multiple inhibition patterns, i.e., immediate or direct inhibition, delayed inhibition, and absence of inhibition. Some researchers explained the inhibition mechanism through using competition between CH 4 and NH 4 + for the same enzyme sites, elevated threshold, salt effect and ion exchange, and N turnover rate and N concentration. However, the inhibitory mechanism is still unclear. Therefore, inhibitory mechanism is one of the main research concerns in future.
