Abstract/Contents: | "The objectives of this study were: 1) observe the seasonal effects of phosphorus on yield, overall desirability and chemical composition of Merion Kentucky bluegrass, 2) compare sampling methods to determine which provided the most reliable estimate of the relationship between phosphorus soil test values and phosphorus In clippings, 4) compare the reliability of soil testing and foliar analysis to accurately determine soil fertility. The experiment was conducted in controlled temperature greenhouses on Caldwell silt loam with a Bray phosphorus (Pl) of 2,2 Kg/ha. Levels of phosphorus incorporation ranged from 0 to 640 parts phosphorus per two million parts soil. Eight clipping dates were utilized for chemical analysis of tissue. Soil tests for phosphorus were taken on four of the eight dates. On these same four dates two methods of sampling, 'first blade' and general clipping, were compared for their ability to provide accurate estimates of nutrient availability, Foliar concentrations of nitrogen, potassium, phosphorus, calcium, magnesium: manganese, iron, boron, copper, zinc, aluminum, strontium, molybdenum, sodium, silicon, and barium, were determined. It was concluded that: I) phosphorus: availability Influenced foliar element concentrations, 2) seasonal fluctuation of foliar element concentrations is significant, 3) physiologically young tissue should be avoided in sampling, 4) the percent of incorporated phosphorus recovered in Kentucky bluegrass clippings during the first 170 days of growth decreases rapidly with increases in incorporated phosphorus, 5) correlations between tissue phosphorus and yield were stronger than correlations between phosphorus soil test values and yield, 6) further studies of the feasibility of utilizing foliar analysis for determining nutrient requirements are needed." |
