Abstract/Contents:"There is much concern in the general public, government regulators and environmentalists as to the impact of fertilizers and pesticides applied to golf courses on water quality. The early studies in this area suggests that fertilizers and pesticides applied to turf had little or no impact on groundwater quality. However, these studies were of limited scope (few or one soil, limited number of pesticides and climatic factors). The objective of this project was to develop a better understanding of the factors and conditions that lead to pesticide and fertilizer leaching from golf type turf (fairways and greens). The leaching of five pesticides (MCPP, triadimefon, trichlorfon, isazofos and metalaxyl) and fertilizer elements (NO3-N, NH4-N and PO4-P) were evaluated under well maintained fairway conditions and tree soil types (sand, Arkport sandy loam and Hudson silt loam). Normal and extremely wet precipitation conditions were also evaluated. Under normal precipitation-irrigation conditions, in general, pesticide leaching was very limited to near zero (with except of MCPP applied to young-thin turf) even with highly leachable pesticides. When conditions were considered "worst case" (thin-immature turf, sand soil, heavy rainfall shortly after application or excessively wet, over-irrigated turf), pesticide leaching was substantial. The leaching of phosphorus from fertilization was zero, even from the sand. Nitrate leaching was limited and only influence by soil type (sand 9%, silt loam 3% and sandy loam 1.5% of the amount applied) not precipitation-irrigation amount. From half (sandy loam) to over 90% of the applied N in the fertilizer was recovered in the clippings, while only 9% was recovered in the clipping from the sand lysimeters. Most of the remaining fertilizer N was found in the soil (as either roots, organic matter or fertilizer). The total estimated N recovery was slightly larger than the amount applied. Generally, there was good agreement in the data between the traditional N source and analytical method and the enriched N15 fertilizer and mass spec analysis to recommend the use of the traditional methods because of a lower cost unless detailed soil and atmosphere N fate is needed."
