Soil nitrogen is important from an agronomic viewpoint, because nitrogen is essential in the synthesis of complex organic substances such as proteins, which are an important source of food for man and feed for animals. The total nitrogen present in most soils is relatively small, and is constantly undergoing many transformations, both chemical and microbiological. However, only a significantly small fraction of the total soil nitrogen is in a form that is available to plants. The ease with which available inorganic nitrogen compounds may be lost from the soil through leaching, erosion and crop removal is an indication of the importance of the study of nitrogen in soils.
