Features

Designed For Professionals

GreenKeeper is a web-based application that can be accessed through the web browser on your computer, tablet or smartphone. It does not need to be downloaded from a mobile app store. Register and sign in at the top of this page.

Product Tracking & Alerts

The GreenKeeper App automatically keeps track of product efficacy, including PGR breakdown with GDD models, and notifies you when control has expired for one of your products.

Nutrient Management

Use GreenKeeper to track your fertilizer applications and monitor changes in soil and tissue test results over time. We have partnered with Rock River Labs to provide full integrated testing experience. Select a test type, enter the site information, print a label, and view your results directly in GreenKeeper a few days after they are received by the lab. Prices range from $20 to $50 and Premium members receive a 10% discount.

Performance Tracker

Turfgrass managers record a lot of data to help make management decisions. Managing that data manually can sometimes be challenging. With the Performance Tracker, managers and maintenance crew members can directly enter green speed, clipping volume, average soil moisture, color, etc. Crew entered data is approved by the course managers to ensure quality before it is then displayed graphically within GreenKeeper. This is a Premium feature and will improve your management precision.

Pest Outbreak Models

GreenKeeper uses hyper-local weather data to help predict pest outbreaks. The Smith-Kerns dollar spot model is now fully integrated into the site. Set your risk threshold and see what cool-season turfgrass areas are protected or at risk of a dollar spot outbreak.

Product Applications Log

You can select an area of your course to treat and choose products and application rates from an extensive turf product database. Then, watch the GreenKeeper App calculate how much product goes into a sprayer tank, the number of tanks needed, and the number of gallons in the mix. When you are done, you can print off an easy to read report with mixing instructions!

Multiple Users

Turf management professionals need to work together and the GreenKeeper App makes it very easy! Just give the App an email and it will add that professional to your course!

Pest Reports

You can tag a target pest ( curative or preventative ) to the products you add to your turf or report pest outbreaks directly to help other turf managers prepare for potential problems. Then, the GreenKeeper App ( with the help of it's users ) compiles maps showing the relative locations of recently reported pests.

Desktop & Mobile Friendly

Designed to efficiently function on both desktop computers and mobile devices, the GreenKeeper App allows users to quickly reference prior applications and monitor pest control while on the course. Have confidence that your mixing calculations are correct and know your turf is covered at any time by simply looking at your phone!

Weather Reporting

The GreenKeeper App monitors the weather so that you don't have to. It's unique tools takes into account local weather conditions and gives you a hyper-local view of how your product application is doing and when it is time to reapply.

About Us

GreenKeeper was originally developed by Dr. Bill Kreuser (@UNLTurf) at the University of Nebraska-Lincoln. Since it has launched in January of 2016, it has grown to be the leading decision-support tool in the turf industry. At the start of the 2018, there are over 4,800 user accounts and 3500 golf courses and sport field complexes using GreenKeeper. Our clients range from smaller budget nine hole golf courses to high budget golf courses that host professional golf tournaments to a broad range of sports turf facilities around the world.

In 2018, Dr. Kreuser partnered with Dr. Doug Soldat (@DJSoldat) to obtain exclusive rights to GreenKeeper as part of TurfGrade, LLC. The transition allows TurfGrade to continually improve the user experience, add the latest research, and cover growing operating expenses. Our company vision is to transform how the turf industry makes daily decisions as we discover and share turf research with the world.
