In agriculture, nitrogen (N) is one of the most important nutrients to improve plant growth and is applied in the form of fertilizer. Plants can take up nitrogen in the form of ammonium (NH4+) and nitrate (NO3-). However, a derivative of ammonium, ammonia (NH3), is also being used by specialized soil microbes. This causes plants to be in a continuous food war with these microbes, decreasing their growth and yield. Once fed, these microbes release nitrate back into the soil....
