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.
The following is from Kevin Hansen, a graduate student at Iowa State, who is working on his masters degree in professional agriculture. It concerns his work with fraise mowing and establishment of sports turf areas.
My name is Kevin Hansen. I am a full time employee of the Iowa State University (ISU) Athletic department working with sports turf management. I am also working on a masters of professional agriculture, with a specialization in sports turf management.
My project centers around establishment of turf areas following fraise mowing (see earlier blogs). I have been involved in the renovation of the football practice field at ISU and am conducting additional work on the process for my creative component.
The objectives of the research are:
1. To determine the best establishment method for fraise mowing.
2. To determine if covers are needed for spring establishment.
3. To evaluate different seeding rates for establishment.
We established the study in a randomized complete block design with three replications. The treatments are as follows:
1 . Control
2. Fraze mowed and grow tarp
3. Fraze mowed, grow tarp, and 5lb per 1000 sq ft
4. Fraze mowed and 5lb per 1000 rate
5. Fraze mowed, grow tarp, and 10lb per 1000 rate
6. Fraze mowed and 10lb per 1000 rate
The study was initiated on April 7, 2014. We pulled the tarps off on May 6. I will be collecting data throughout the spring.
Here is the area right after fraise mowing on April 7, 2014.

Tarps made a big difference initially.
