- W4243396744 abstract "This chapter discusses the factors affecting the nitrogen content of soils. Under virgin conditions the organic matter and nitrogen content of a soil approaches an equilibrium value, the magnitude of which depends primarily upon climate, vegetation, and the physical characteristics of the soil. Soil organic matter contains nitrogenous complexes that are important from the standpoint of fertility. The biological resistance of organic soil nitrogen is indicated by the fact that less than 4 percent becomes available in any one season. Soil nitrogen is usually considered to be proteinaceous in character but it is much less available than the nitrogen in ordinary proteins. As organic residues decompose, there is a narrowing of the C:N ratio until an equilibrium ratio of about 12:l is reached. During the process of decomposition, the nitrogen in the residues becomes less and less available. When soil organic matter decomposes, ammonia is liberated and under favorable soil conditions it is converted to nitrate." @default.
