| Abstract/Contents: | "The phosphorus level in a soil is considered to be one of several factors which influence the phytotoxicity of arsenic. An established Kentucky bluegrass sward was fertilized in the fall with three rates of phosphorus: 0,75 and 150 lb. P205/a. The soil was a Nixon sandy loam which was low in available phosphorus. Two pH levels, 5.O and 6.0, were established by additions of sulfuric acid. "Low lime" tricalcium arsenate at 0, 3, 6 and 9 lb. of As per thousand square feet was applied the following March. Grass was harvested in June and August of the same year. The arsenic and phosphorus concentrations in the grass were not affected by the additions of phosphorus to the sward. The higher pH slightly decreased the arsenic content of the grass. The application of higher rates of arsenate slightly increased the arsenic concentration. There was no visible sign of injury to the bluegrass. In the greenhouse Merion bluegrass and crabgrass plants grown in a nutrient solution with 10 ppn of phosphorus were preconditioned for one week in nutrient solutions having 1, 10 and 100 ppm of phosphorus. "Low" lime" tricalcium arsenate and sodium arsenite treatments were applied and the plant tops harvested 24, 48 and 72 hours later. High levels of phosphorus in the nutrient solution reduced the phytotoxicity of the arsenate treatments to practically nil, but they did not influence the phytotoxicity of the arsenite treatment. The phosphorus concentration in the bluegrass tops grown in the 100 ppn P nutrient solution was five fold greater than that in the bluegrass grown in the 1 ppm P nutrient solution. Bluegrass from the 1 and 100 ppn P nutrient solutions contained two to three times as much arsenic as bluegrass grown in the 10 ppm P nutrient solution. On the other hand, crabgrass had the most arsenic when grown in the 1 ppm P nutrient solution and by far the least when grown in the 100 ppn P nutrient solution. "Low lime" tricalcium arsenate was synthesized in the laboratory and tagged with As76. This was applied to nutrient solutions as above. The bluegrass and crabgrass tops were harvested 9, 18 and 36 hours later, digested and counted for As76 The results were similar to those obtained previously. There was more arsenic in the bluegrass grown in the 1 and 100 ppm P nutrient solutions than in that grown in the 10 ppm P nutrient solution. Likewise, crabgrass grown in the 1 ppn P nutrient solution had a much higher concentration of arsenic than crabgrass grown in the higher phosphorus nutrient solutions or than bluegrass grown in the 1 ppm P nutrient solution." |
