Abstract/Contents:"This project is designed to examine the leaching potential of nitrogen, phosphorus, and pesticides under realistic field conditions. Four lysimeters, devices for the collection of soil water, have been installed at the Hancock Turfgrass Research Center (HTRC) on the Michigan State University Campus. These lysimeters are 1 m2 in surface area and 1.2 m deep. The soil within the lysimeters are intact cores that were not disturbed during the construction of the lysimeter. We believe that the data from these lysimeters will reflect conditions that occur naturally in the field and that the data will give a clear picture of leaching potential for the soil (Owosso sandy loam) used in this study. The project consists of three separate areas. First, the leaching of nitrate from late-fall versus early spring applications will be studied using 15N labeled urea. This study will also examine the fate of nitrogen over a three year period and will focus on the cycling and forms of nitrogen in the soil. As a second approach to the study, pesticides will be applied to the lysimeters and the leachate tested for the presence of these pesticides over the next three years. A total of five fungicides, two herbicides, and one insecticide will be applied. In August the insecticide Triumph and the fungicide Daconil were applied to the lysimeters and in September the herbicides 2,4-D and MCPP were applied. The other four fungicides will be applied in 1992. The other area of the study is to examine the mobility of phosphorus in greens soil mixes. Phosphorus has little mobility in soils with appreciable clay content, however, movement can occur in soils that are mostly sand. This study will collect samples from recently constructed greens around the US and test these mixes for phosphorus adsorption capacity. Also, phosphorus mobility on pure sand greens will be examined at the HTRC. Results from our first summer of monitoring are not available at this time due to the intensive nature of the laboratory anaylsis required to determine 15N quantities. Data on the quantity of leachate is interesting since it demonstrates that under periods of high ET demand, little leaching occurs. From May 1 through August 28, the lysimeters received a total of 60 cm of rainfall plus irrigation. However, only 4 cm of leachate were collected from the lysimeters. From August 29 through September 16, an additional 8 cm of rainfall plus irrigation were received while the lysimeters leached 4.8 cm of water. Thus as ET demand slacks the soil moisture level throughout the whole core rises and rain or irrigation will cause leaching. These data point out the importance of irrigation management to reduce the potential for leaching. Data will be available in 1992 on teh 15N and pesticide content of the leachate as well as data on the cycling and movement of 15N through soil."
