Soil nitrification is a biological process that converts ammonia to nitrate. Excess nitrate is prone to leaching, which results in financial loss for farmers and water pollution. It is known that ammonia oxidizing archaea (AOA) and ammonia oxidizing bacteria (AOB) are able to nitrify, but it is unclear how much they contribute to this process individually. To answer this question, we conducted an experiment at the Kellogg Biological Station (KBS) Long Term Ecological Research (LTER) site to determine how AOA and AOB contribute to soil nitrification. Soil samples were taken from seven different ecosystems including Conventional Wheat (T1), Biologically Based Wheat with Cover Crop (T4), Poplar (T5), Early Successional Community (T7), T7 fertilized subplots, Deciduous Forest (DF), and DF fertilized subplots.Get poster
