Due to its inherent microbial nature, nitrification in soils is greatly susceptible to soil conditions. In general, soil nitrification will proceed at optimal rates if the conditions for the microbial communities foster healthy microbial growth and activity. Soil conditions that have an effect on nitrification rates include:
*Substrate availability (presence of NH)
*Aeration (availability of O)
*Soil moisture content (availability of HO)
*pH (near neutral)
*Temperature
