The organic forms of nitrogen in the soil are derived largely from plant residues, such as stubble, weeds, leaves, and pine needles etc. The amount of protein in these organic materials is often very large. For example, the protein content of cereal straw and wood shaving may be as much as 2 or even 15 per cent, and the protein content of certain defatted meals, may be 40 or even 60 per cent. The phenomenon of growth and death of bacteria in ordinary culture media has been studied in considerable detail.
