Few Azotobacter in soils below pH 6.0, according to early studies; need several thousand colonies per gram of dry soil to get appreciable N fixation: liming increased Azotobacter in acid soils; phosphorus addition had no effect; large seasonal fluctuation in Azotobacter; highest numbers in spring and fall. T: Seasonal Azotobacter changes; effect of pH, lime, P.

Two lime studies with winter wheat reported in earlier progress reports were continued in the fall of 1987. One study was initiated at the Sandyland Experiment Field on August 27, 1982 to determine the lime response of winter wheat on a Carwile sandy soil and the optimum liming rate, and to compare the SMP buffer lime requirement with the field-determined lime requirement. On September 18, 1985 another lime study was initiated near Norwich, KS (Kingman County) on an acidic Farnum loam of soil. The objectives were to compare the effectiveness of agricultural liming materials to pure calcium carbonate and to determine the yield response with a heavier textured soil.
