Effect of Fraise Mowing on Soil Physical Properties

Fraise mowing is an ultra-aggressive cultural practice that purges plant and soil material from 0 to 5 cm depths. Fraise mowing may remove surface crusts and compaction thus improving infiltration, soil oxygen, and root growth. Click here  to learn more about research evaluating fraise mowing as a viable cultivation method to remove surface compaction.

Water Conservation Practices Mitigate Nutrient Losses from Turf - Deficit Irrigation and Fertility Effects on NO3–N Exports from St. Augustinegrass

Dense, healthy turfgrass can retain properly-applied nitrogen fertilizer with minimal nutrient loss to the environment. In the southern U.S., urban water conservation strategies often include reduced irrigation programs which can diminish the health and density of turfgrass temporarily. In a two-year field study, researchers investigated the effects of water-conserving irrigation practices on runoff volume and nutrient losses from turf.

Pollinator BMPs in Turfgrass

Insects are the most common and abundant pollinators in our world today. Although bees may be the most well-known insect pollinators, there are many other different insect species, including butterflies, moths, wasps, flies and beetles, that can also play an important role in plant pollination.

Biological Control of White Grubs in Turf with Microsclerotial Granules of Metahizium brunneum (Mb)

USDA's Agricultural Research Service and Purdue University researchers are working together to develop biological controls that protect turfgrass against white grubs. Click here to learn about how the fungus Metarhizium brunneum is being evaluated for control of larval stages of Japanese, June, and other scarab beetles.

Fall Field Preparation

The fall sports season is almost upon us. Don't forget to utilize all STMA's technical resources to help prepare your athletic fields for games, practices, and recreational use. STMA offers a wide variety of information pertaining to field safety, renovation practices, and general preparation.

Grueling Turf Tests at UMass Amherst to Enhance Quality and Safety of Tennis, Other Grass Sports

Researchers at University of Massachusetts Amherst's Joseph Troll Turf Research and Education Center are evaluating turfgrass tolerance under actual tennis play. This project is notable as the first and only funded research project to investigate turfgrasses that are optimal for tennis. Click here to learn more.

Irrigation Water Testing and Interpretation

Irrigation water management is an important component of a successful sports turf management program. Regardless of your water source, it is important to test your irrigation water so you can successfully manage your field in the best way possible. Click here to learn how to properly take a water sample and what to do once you get your irrigation report back from the lab.

The NFL’s Engineering Roadmap: Driving Progress Toward Better Protective Equipment

Experts from The Center for Applied Biomechanics at The University of Virginia are studying game-day player impacts with crash-test dummies. The work aims to understand more about how head injuries happen on the football field, and use what's learned to catalyze the design of better protective equipment in the future.


#PoaDay is an annual Field Day event hosted by members of the turfgrass and ornamental weed science team at the University of Tennessee. The event was recorded and is available on-demand on the event's Facebook page. The University of Tennessee team addressed the emerging problem of herbicide resistance evolving in turfgrass weeds, particularly annual bluegrass.

Selecting Turfgrasses and Mowing Practices that Reduce Mowing Requirements

Mowing is one of the most fundamental and energy-intensive cultural practices in maintaining turfgrass. Mowing is a plant stress, even when done correctly. It reduces the plant's ability to undergo photosynthesis and produce carbohydrates, and can reduce rooting capacity.
