Hi-Res Surface Organic Matter Analysis in GreenKeeper

Surface organic matter has always been one of the most important—and frustrating—variables to manage on putting greens. We know it influences firmness, infiltration, water holding capacity, and pest pressure. We also know that topdressing and cultivation are our...

Why Your Rainfall Data May Be Wrong: The Challenges of Estimated Precipitation

GreenKeeper, like the weather apps on your phone, uses extremely high-resolution weather models to estimate current conditions and forecast future weather. These systems combine observations from airports, weather balloons, satellites, and weather radar with...

A Completely New WhiteBoard Experience for Turf Managers

GreenKeeper WhiteBoard has been rebuilt from the ground up with a modern user experience, intelligent planning tools, and unmatched flexibility for daily turf operations.Daily labor planning in turf management is complicated. Every day, turf managers balance changing...

Your Spray Program Shouldn’t Keep You Up at Night

​Building a spray program can be stressful. You're thinking about pest control, fertility, PGRs, wetting agents, and plant health products. Are products from the last application still doing the job? Then comes the mixing math. A misplaced decimal or a wrong unit can...

Moving Beyond Pretty Maps

Today's weather forecast shows a 10% chance of rain in the late morning. Do you throw your rain gear in the cart? What if the forecast shows a 30% chance at 7:00 a.m.? Even without formal training in statistics, we use probabilities like these to make practical...

GreenKeeper Models Provide More Insight Than Simple GDD Calculators

​I first learned about growing degree days (GDDs) in my introductory agronomy course at UW–Madison. These models used daily average temperature to predict biological processes such as corn development. I later learned that GDDs could also be used to schedule seedhead...

Upgraded GreenKeeper CIS Includes POGO Integration

Many turf management decisions are inherently spatial—where water is needed, where pests typically occur, and where additional management is required to achieve specific performance goals. Historically, these patterns have been managed through careful observation,...

Learning the Microclimate: GreenKeeper Insight Improves Forecast Accuracy

Accurate weather forecasts are central to irrigation scheduling, spray timing, and stress management, yet most forecasts are built for regions—not individual golf courses or athletic complexes. Terrain, tree cover, elevation, and nearby bodies of water create...

Move Past Yesterday’s ET: The Predictive Advantage of GreenKeeper wX

Agronomic models are only as good as the data they receive. GreenKeeper’s models rely on high-quality, site-specific weather inputs to perform at their best. Adding a wX station dramatically improves the accuracy and resolution of those data. While weather stations...

Measure & Predict Organic Matter in GreenKeeper

Measure & Predict Organic Matter in GreenKeeper

Management of soil organic matter (SOM) accumulation is a primary concern for turf managers. Cultivation practices including topdressing, aeration, verticutting and DryJect sand injection are used to manage SOM, but how often are these practices required? GreenKeeper App now support loss-on-ignition SOM determination at three different depths (OM246). Those results are then used to predict SOM accumulation over the next three years.

August Sugar Lows

August Sugar Lows

It’s the middle August and many turfgrass plants are feeling as tired as their turfgrass managers. The recent extreme heat is taxing cool-season grasses like ryegrass, bluegrasses and bentgrass while summer weeds like goosegrass, foxtail and crabgrass are thriving....

How much grass WOULD have been in the buckets?

How much grass WOULD have been in the buckets?

For years, golf course superintendents have asked the question to their greens mowing crew, "How much grass did you get today?" Common answers usually included "a lot" or "a little" or maybe more precisely how many times they needed to dump the mower buckets. But have...

Growth Rate Goals

Growth Rate Goals

We have been advocating daily measurement of growth rate on highly maintained turfgrass to improve management precision. Clipping volume measurements provide actionable data to help guide PGR applications and evaluate the efficiency of a fertilization program. But how...
