The following is content from the Ohio Lawn Care Seminar presentation “Soils & Fertility for Healthy Lawns & Sports Fields” given June 15th, 2017 in Wooster Ohio.
Attendees are invited to spend time looking at disease trials and hear about current and new fungicides. There will be an update on the diagnostic clinic and time for a Q&A session.
This is an ideal opportunity for turfgrass managers to spend time with Joe Rimelspach & Todd Hicks and get the most up-to-date information on turfgrass disease issues.
The event is free.

Today is my last day working with Pam Sherratt as a Turfgrass Student Assistant. It is a huge honor to work with Pam and many of the students, people from the turfgrass industry plus faculty and staff that I get the pleasure to work with during my two years at Ohio State. I am graduating on May 7 and receiving my Bachelors of Science degree in Turfgrass and minor in Plant Pathology. I have accepted Continue reading
If surface water is not removed from the field:
- Surface becomes slippy and unsafe, as well as providing a poor spectacle
- Soil compaction will occur more readily on cohesive native soils, increasing surface hardness
- Oxygen is excluded from the soil and roots will not grow = grass pulls out during games & grasses will not be as stress tolerant (e.g. drought stress)
- Anaerobic conditions develop, leading to black layer problems & lack of important nutrients
- Cancellation of events/games
- Delayed maintenance practices e.g. mowing
- Increase in pest & disease problems (annual bluegrass etc.) because of wet favorable conditions or reduced grass health
- Soils take longer to warm up, so seed germination is delayed in spring

On April 21, the Turf Club was represented at the Ag Olympics competition. It was an event that had 12 other college fraternities, sororities, and organizations from CFAES competing for the top prize. Events included best uniforms, tug of war, backyard jenga, water balloon toss, etc. For their first appearance at the Ag Olympics in 28 years, the Turf Club came in 3rd place!
The Turf Club also sponsored the golf outing held at Homestead Springs Golf Course on April 23rd. During the event, over 28 sponsors and 24 teams participated at the outing. The total money raised at the outing was $4,500! The money raised will go toward the OSU Turf Club for expenses such as taking students to represent Ohio State in Turf Bowl competitions at GIS and STMA conferences in 2018. Thank you for those that came out for the golf outing. Continue reading
Some soccer field managers are asked to apply water just prior to a game. Why is that, and how much should be applied? During my own experience as a soccer player, and also as an agronomist, I have seen a variety of watering requirements from coaches, managers, players and grounds managers prior to a soccer game. Continue reading

In addition to leaf area, a direct relationship exists between the height of the turfgrass and the depth and total mass of the root system. Continue reading
Calcined clay is a popular soil amendment used on baseball infields for water management and soil conditioning. Clay is heated at a high temperature, about 1500 degrees Fahrenheit to expand the clay forming calcined clay. On baseball fields calcined clay is used to fill in infield depressions caused by cleats and smooth the surface to provide a true baseball bounce, which contributes to the safety of the field. Calcined clay absorbs water that can help dry a field after a rainstorm, and firm the surface. Continue reading

Creeping bentgrass is considered a weed on athletic fields and lawns. It produces a superb playing surface for golf and it has great recuperative potential, but it’s shallow roots and lack of wear tolerance make it unsuitable for most athletic sports.
Tenacity (mesotrione) is the first herbicide that results in rapid, easy to visualize reductions in weedy perennial grasses, including creeping bentgrass. Best control, according to most research of creeping bentgrass, is achieved if three applications are made on 14-21 day intervals. Continue reading

Extended periods of cool, wet spring weather this year has triggered extensive leaf spot on lawns. This is a troublesome spring diseases on Kentucky bluegrass (especially common bluegrasses), fescues and other lawn grasses. Some leaf spot can be found on most home lawns in the spring, but it normally does not cause significant damage to the lawn. This year due to the weather conditions leaf spot has occurred and now in progressing into the melting-out phase. Leaf spot is caused by several different fungi. The fungus overwinters in the thatch layer or in small lesions on leaf blades. Continue reading
