Abstract

Synopsis Yield of dry matter was affected very little by applications of phosphate fertilizers when soil temperatures were maintained at 50° F. regardless of available phosphorus in the soil. At 65° and 80° F. soil temperatures, applications of phosphate doubled the yield of dry matter on a low phosphorus soil and had a variable effect on the high phosphorus soil. Phosphorus percentage of the top growth was not affected by soil temperature but was increased considerably by the application of phosphate to the soil.
