The Benefits of Aerification

The Rim Golf Club is a unique club. The breath taking views from every hole are like no other golf club in Arizona. The idea that we live in a desert climate is sometimes forgotten when we live among the largest forest of Ponderosa Pines in America. There is no doubt; it is tough to find a better environment to enjoy playing the game of golf.

Growing grass in Payson is much different than anywhere in the State of Arizona. Cool season grasses grown on decomposed granite is not accomplished anywhere else in the State. Sedona, Flagstaff, The White Mountains, all have more desirable soils to work with. Sedona is the closest to our climate with warmer summers to cause substantial disease pressure in the Monsoon months. The northern courses will never experience destructive disease like we do. Cooler overnight temperatures keep pathogens in check.

A frequently discussed subject among members is our soil or lack of. Adding soil or organic matter has been a topic for as long as I can remember. This could sound like I am contradicting myself, but we don’t have a problem with not having enough organic matter, actually we grow all of our grass in a two inch thick blanket of organic matter (thatch) that caps our native granite soil. We can utilize this organic layer by incorporating inorganic sand to create an optimum playing field. An ideal soil is shown in this diagram. If you notice mineral (rock, gravel) is a key ingredient. Organic is only a minor piece of the pie.

Building a soil is a slow process. The inability to make use of our native soil has become a reality. Making use of the organic matter (thatch) we have in place and mixing in sand through aerification and topdressing we can create a decent growing medium for turf. It is a slow process. I have been here for four seasons and three years ago we started a consistent cultivation program. The benefits of incorporating sand have been fairways that are more firm, slightly better water infiltration through the organic matter and a healthier root structure. Benefits we will see with continued cultivation will be less disease pressure due to better drainage, deeper roots that will endure drought better and utilize nutrients and water more efficiently. Aerification can be a dirty word in the golf community, but to a turf manager it is literally a breath of fresh air.

In my opinion, Payson is located in the most beautiful area in Arizona. Complementing the surrounding environment is quite a challenge as a turfgrass manager. Grass, being a living organism, needs adequate oxygen, water, and light. Aerification is the most important practice to oxygenate the soil, a practice that is needed twice a year to enhance the course’s future. Conditions will only improve over the years with consistent cultivation.
