Josh Lenz is a new graduate student who is working on a masters of horticulture at Iowa State University. He is doing the non-thesis option and will complete a creative component. He works full time with the athletic department.
Josh will be looking at chemical and physical changes in the soil of sand-based sports fields subjected to repeated painting.
His treatments include:
1. Untreated control
2. Aerosol paint
3. Acrylic paint 1:1 with water
4. Acrylic paint 2:1 with water (two part water:1 part paint)
5. Acrylic paint 4:1 with water
He will be painting the plots weekly through the season. His measurements will include cation exchange capacity, nutrient holding capacity, water infiltration rates, bulk density and a variety of other physical soil parameters. The study will go on for two years.
