Pesticide Soil Organic Matter Microbial Degradation Adsorption Leaching
Turfgrass & Pesticide Applications • In established turfgrass environments: • Pesticides are not applied directly to soil • Larger, more diverse microbial populations are supported
Pesticide Binding Capability • Organic matter layer near soil surface of turfgrass system effective in binding pesticides • 4 yr • 21 yr • 99 yr
Materials and Methods • Five herbicides included:
Analyte RecoveredPooled over atrazine, mesotrione and sulfentrazone µg kg -1 (ppb) Vegetation, aboveground vegetation. Surface soil, 0 – 4 cm. Subsurface soil, 4 – 91 cm.

Turfgrasses Add Value Turfgrasses add value to the landscape and offer many benefits to society and to the environment.
