Soil Nitrogen

Soil nitrogen is prominent among the many nutrients essential for crop growth and has probably received more study and attention than any other. Nitrogen occupies a unique position among the major nutrients because it occurs only in trace amounts in soil parent materials but is required by plants in relatively large quantities. At a time when food production is an increasing concern in the world, a monograph on the general subject of soil nitrogen is pertinent and timely. Cropping systems have been much influenced by the availability of synthetic nitrogenous fertilizers and it appears that this trend will continue with the steadily increasing efficiency of chemical technology. A major objective of modern soil science and agronomy is to put together farm management systems that will maximize the efficiency of food production and reduce costs. This monograph summarizes known facts and principles for an important component of the system and therefore will find extensive application and use.
