Bacterial etiolation or "Mad-Tiller" disease is a very frustrating growth disorder that has perplexed many turfgrass managers and researchers. While the Kerns and Vargas labs have independently shown the rapid leaf growth rate is most likely the result of bacterial...

Not all precipitation events are created equal. That was definitely the case in Southeast Nebraska during the last week of July 2024. The high temperatures had been around 100F with dew points were in the 70s. Any storm that develops during those conditions can...

The Water Resource Planner in GreenKeeper App is the most powerful irrigation scheduling tool in the professional turfgrass management market. It uses advance agronomic and meteorological models to predict changes in soil moisture with hourly resolution. While the...

It's always a tough call. Should we irrigate tonight or stretch it another day? Make the wrong decision and you'll be hand-watering wilt tomorrow afternoon. So you decide to water, but how many minutes are required? Over-watering not only wastes water and money, but...

I can assure you that this simple task, taking less than one minute each day, will provide valuable insight that directly impacts agronomic decisions. It is the most valuable piece of data that I collect, and it’s my biggest pet peeve when it’s skipped. This measurement predicts putting green performance, helps schedule mowing and topdressing frequency, and guides PGR and nitrogen application rates. It also helps me manage high and low performing greens differently. Still, there are a lot of questions about how to collect, log and use the data. This short article will help answer those questions.

There are literally hundreds of soil wetting agents in the turfgrass management industry. Some are marketed to retain water while others to move it. Some claim to increase surface firmness while others supposedly reduce firmness. Labeled re-application intervals range...

Geospatial data is becoming increasingly important to turf managers. These data link observations and measurements to specific locations (latitude/longitude).  Examples include locating the position of pests and problem areas, mapping irrigation head and value...
