  12. Carbon Sequestration Potential • Forest plantations: 4 ton / ha (2.5 acres) / yr • Turfgrasses: 1 ton / ha (2.5 acres) / yr • 16.4 million ha (40.5 million acres) of turfgrass area in US Jackson and Schlesinger 2004, PNAS 101(45):15827-15829 Qian and Follett 2002, Agron J 94:930-935 Milesi et al. 2005, Environmental Management 36(3):426-438

  22. Pesticide Soil Organic Matter Microbial Degradation Adsorption Leaching

  23. Turfgrass & Pesticide Applications • In established turfgrass environments: • Pesticides are not applied directly to soil • Larger, more diverse microbial populations are supported

  24. Pesticide Binding Capability • Organic matter layer near soil surface of turfgrass system effective in binding pesticides • 4 yr • 21 yr • 99 yr

  25. Materials and Methods • Five herbicides included:

  27. Analyte Recovered Pooled over atrazine, mesotrione and sulfentrazone µg kg -1 (ppb) Vegetation, aboveground vegetation. Surface soil, 0 – 4 cm. Subsurface soil, 4 – 91 cm.

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