"Holganix helps build my soil chemistry" - Orchid Island Golf & Country Club

Tucked on a barrier reef island, off the coast of Vero Beach, Florida, lies Orchid Island Golf and Country Club. Originally designed by championship golfer Arnold Palmer, Orchid Island’s course features eighteen-holes of immaculate greens, tee boxes and fairways.

In 2005, Orchid Island, “achieved the distinction of becoming a certified Audubon cooperative sanctuary by Audubon International Sanctuary System, the education Division to Audubon International, which recognizes environmental stewardship.”

According to superintendent, Matthew Boyd, “Orchid Island is an atypical environment.” It’s in a microclimate all of it’s own, with sandy soils and an ever present sea wind that keeps the soil dry. It makes nurturing the course a challenge but one Boyd takes pleasure in.

“Holganix helps build up my soil chemistry,” explains Boyd, something that’s crucial for a course like Orchid Island. Over all, Holganix helped Boyd improve rooting, CEC levels and carbon to nitrogen ratio.

 

Increasing turf rooting 

The first thing Boyd noticed after starting Holganix in 2014 was “deeper, denser rooting on greens.”

Initially, he also saw improved playability due to increased consistency on his greens, and less disease than years past (although he admits that it’s hard to quantify reductions in disease due to variability in past years).

 

Improving CEC Levels and C:N Ratio 

Perhaps the easiest way to sum up Boyd’s superintendent style is data enthusiastic. He constantly monitors the course’s progress and has teamed up with an agronomist to better research and customize his agronomic program.

When it comes to Holganix, the thing that blew Boyd away were his soil analysis results which were taken one year after incorporating the Holganix program along with other various organic profile amendments. Included in the data summary were huge improvements to Cation Exchange Capacity (CEC) along with the soil organic carbon to nitrogen ratio.

“We had steady improvements in soil health both before and after Holganix, especially with our CEC,” says Boyd.

What does CEC mean? Think of it this way, the soil acts as a pantry/storehouse for all plant nutrients required by the plant. The soil’s ability to hold, maintain and release essential nutrients is Cation Exchange Capacity. So, the greater the CEC, the more nutrients the soil can store and the happier the plant.

From 2010 to 2013, Boyd utilized an alternative biological supplement and had a slight, yet steady increase in CEC achieving 4.81 M.E. in 2013. One year after incorporating Holganix into Orchid Island’s agronomic program, Boyd reports an increase in CECs from 4.81 in 2013, to 7.78 in 2015! That’s over a 60% increase!

Also revealed in the soil test was a noticeable difference in organic matterOverall, organic humus has increased from .42 to 2.8% – something that is crucial to the health of sand-based soils. Why is humus crucial to sandy soils? It increases the soils capacity to hold and store essential plant nutrients, decreases the potential for leaching, assists in the remediation of excess sodium and bicarbonate and provides a sustainable food source for both plants and beneficial soil biology. Yet, thatch has decreased. “That’s because the biology within Holganix was converting all of the old growth found in the organic matter into nutrients that are available to the plant,” explains Boyd.

Furthermore, Boyd’s soil organic carbon to nitrogen ratio increased dramatically after one year of Holganix. “My carbon to nitrogen ratios are better than they used to be,” says Boyd. “That’s awesome because all of that free carbon is food for the microbes and the microbes just take off!”

Overall, Boyd is excited by the progress he’s seen with Holganix at Orchid Island. “Soil microbiology is going to be a hot topic in the next ten years and Holganix is right in the middle of it,” says Boyd.
