Abstract
THE ordinary denitrification taking place in the absence of oxygen and in presence of an easily oxidisable organic substance and a nitrate effected by many micro-organisms, is well known. There is another variety of nitrogen loss, which takes place in presence of oxygen, but has not yet been satisfactorily explained. It will be evident that this loss of nitrogen from the soil, which may amount to double the quantity of nitrogen taken up by plants, is due to an oxidation process followed by a photochemical and catalytic decomposition.
