Abstract/Contents:Discusses factors that may affect the accumulation of nitrate nitrogen in the soil. Explains that "nitrates are produced from ammonia by a process of oxidation by two groups of bacteria. Such bacteria are specialized workers. If conditions are unfavorable to them the production of nitrates must stop because there are no other organisms to do this particular job." States that "since the process is one of oxidation, plenty of oxygen must be present. Soil that is packed or wet has little and sometimes no air (oxygen) space. Plants growing on wet soil often show yellow leaves and look sickly, largely because they cannot get the nitrogen needed." Notes that "heavy soils (silts, clays, loams) are the ones that pack worst." Emphasizes that "by far the most important single factor in the production of nitrates is soil acidity."
