 Spot Treating with the DryJect

 

 

 

 

Last Friday, February 14th, we had the opportunity to DryJect a few areas on our putting surfaces.  This machine takes a dry material(sand/soil amendment) and injects it into the soil profile.  This unique process uses high impact water to open a channel, creating a vacuum that pulls the dry material into the soil profile.  The machine is equipped with a high density roller that smooths the surface following the injection.  We took the extra step of brushing off the excess material and rolling the treated areas to provide optimum playing conditions. 

 

The DryJect operation is typically used in the summer months in conjunction with normal aerification.  This ensures proper distribution of topdressing throughout the green and aids in the dilution of thatch.  This spot treatment was scheduled to treat the few areas that needed supplemental soil amendments.  The product we used will increase soil porosity, help in moisture retention and increase the Cation Exchange Capacity(CEC).  The CEC is a measure of the turf's ability to attain and exchange nutrients through the soil.  We have seen some improvements in the growth rate and will continue to encourage recovery.  We will encourage recovery and focus on playability through the remainder of the golfing season. 

 

Thank you for your patience and support.  I look forward to measuring the results of the DryJect operation and determining its place in our agronomic plan.

The Ebb and Flow of Environmental Conditions

 

2014 has proved to be an unpredictable year with regards to the growing conditions for our golf course.  The first two weeks of the year, gave us cloudy and wet conditions.  This was followed by unusually cold weather that produced our first two frost delays of the season.  We bounced right back from that cold spell with record high temperatures in early February.  These varying conditions each have a unique impact on growing conditions and maintenance practices.

 

The cloudy and wet weather impacts the rate of photosynthesis in the plant due to the lack of available sunlight.  This results in a plant that is more susceptible to disease and has a low tolerance to stress.  We combat these conditions with preventative fungicides and a decrease in mechanical stresses. 

 

As we moved into the sustained cold weather, the soil temperatures dropped to the point where turf growth was halted.  To maintain aesthetics and playability we spoon feed the turf with foliar applied nutrients. 

 

Last, but not least, our "Spring Green up" in February.  As the soil temperatures rise the turf begins a rapid recovery.  The stored carbohydrates are released based on a priority system.  The first priority goes to seed production, which is non-existent in our turf grass.  The second priority is allotted to the stems and leaf blades.  The final destination for the stored carbohydrates is the roots.  This results in an overabundance of top growth and a shallow root system.  The end result typically comes in the form of slower putting surface for the first 5 to 7 days and localized dry spots soon to follow.  The following pictures depict some off color turf on the putting surfaces due to the dry conditions.  I am pleased to see the dry areas, because we have not had these conditions since May of last year.  We will hand water these areas until a proper balance of moisture is attained throughout the putting surface.

On another note, I attended the Golf Industry Show in Orlando last week.  My three day trip consisted of two days of education and one day of walking the Trade Show floor.  My classes included Managing Rootzones in a Southern Climate, Ultradwarf Greens Maintenance Practices and Preparing for Certification.  The knowledge gained during this time ranged from university professors, USGA agronomists and countless networking with fellow turf professionals.  This is a great opportunity to re-affirm the practices we have in place as well as pick up on a few new ideas.  I appreciate the support from the entire Stonebridge community as I further my education to provide superior conditions for our property.
