It’s Aerification Season. Are You Ready?

Posted by Tony Goldsby, Agronomist on March 09, 2020


Determining the right fertility approach for your aerification program can be a difficult task. The choice to apply fertilizer before, during and/or after mechanical aerification provides unique options for ensuring your turf recovers quickly.

Below, we’ve outlined a collection of our premium products best suited for aerification applications.


 

Aerification Recovery

The process of mechanical aerification is a necessary management tool to improve airflow, nutrient and water movement through the soil profile. Following this destructive process, it is vital to jumpstart turfgrass recovery to a quality level necessary to resume play. Genesis Rx Zeolite+ is a 50/50 physical blend of Genesis Rx 5-7-5 and zeolite dispersible granules with beneficial microorganisms. Zeolite which is a natural mined material has a high CEC, high porosity, and excellent water retention capabilities. Genesis Rx Zeolite+ delivers balanced NPK, secondary and minor element fertility, soil enriching humic acid, zeolite dispersible granules, and beneficial microorganisms all in one easy to apply product.

Turf Grass Recovery Post Aerification


 


Genesis Rx 5-7-5 features a combination of readily-available and slow-release nitrogen, secondary and minor elements, and Dispersing Granule (DG) Technology. This unmatched combination provides turfgrass with the necessary nutrition for optimal growth.

APPLICATION

Genesis Rx 5-7-5 for turfgrass maintenance range from 5-20 pounds of product per 1000 sq. ft.


 


 

Contec DG 18-9-18 is one of the most popular greens formulations in our premium fertility offering. Many golf course superintendents already use this product in their baseline fertilizer programs, making it an easy addition to aerification programs. 

APPLICATION

Contec DG 18-9-18 can be applied in preparation for aerification at a rate of 2 pounds of product per 1000 ft2. For complete application instructions, consult product label.


 



Humic DG is a powerful humic acid-based soil amendment perfect for application following aerification or other intensive maintenance practices. Humic acid is a natural soil conditioner, organic chelator, and microbial stimulator. Containing all three humic fractions (fulvic acid, humic acid, and humins) delivered with a dispersing granule, Humic DG is the perfect counterpart for sand topdressing or in conjunction with other premium aerification products such as Genesis Rx 5-7-5.

WHY HUMIC ACID?
Humic acid is a natural soil conditioner, organic chelator, and microbial stimulator that provides the following benefits:

  • Supplies an oxidized, soluble carbon source, leading to improvement in long-term soil pH
  • Enhances efficiency of applied nutrients and increases availability of soil phosphorus
  • Retains soil moisture and enables better water penetration in the soil, resulting in reduced water requirement
  • Chelates soil micronutrients, increasing their availability

APPLICATION
Humic DG is recommended for application after aerification as a top-dress treatment. Typical application rates range from 1-2 lbs. of product per 1000 ft2, and can be mixed directly in with sand for easy application. For complete application instructions, consult product label.


 



Black Gypsum DG 21% is a unique soil amendment containing gypsum and humic acid in a homogenous dispersible granule. In past years, gypsum applications made with the anhydrite (CaSO4) form of calcium (one water molecule), could take weeks to become available for plant uptake. This prolonged uptake process severely limited a turfgrass manager’s ability to jumpstart the soil remediation process.

The gypsum source in Black Gypsum DG 21% is calcium sulfate dihydrite (CaSO42H20). With two extra water molecules, this form is more water soluble than the anhydrite form (CaSO4). This improved solubility means that uptake into the turfgrass plant occurs much quicker. The dihydrite form of gypsum also provides increased application flexibility for year-round soil remediation versus standard anhydrite forms of gypsum.

APPLICATION
Black Gypsum DG 21% is recommended for application after aerification as a top-dress treatment. Product is typically applied at 6 lbs. per 1000 ft2, and can be mixed directly in with sand for easy application. For complete application instructions, consult product label.


 


DG Lime and DG Gypsum are premium specialty soil amendments. DG Lime provides plant-essential calcium and magnesium, while increasing soil pH. In addition to calcium, DG Gypsum also provides sulfur, which stimulates soil microbiology while reducing soil pH. Both products feature Dispersing Granule Technology, which ensures quick breakdown of the granules with no residual left behind for potential mower pickup.

APPLICATION
DG Lime and DG Gypsum are recommended for application after aerification as a top-dress treatment. Typical application rates range from 25-40 lbs. per 1000 ft2, and can be mixed directly in with sand for easy application. For complete application instructions, consult product labels.

The Turf Nutrition Tool (TNT) is a web-based platform that allows turf managers to create custom nutrition programs and model the nitrogen release of many of our most popular granular and foliar products.

This latest version of the TNT has been completely reimagined to include:

• A mobile-friendly tool accessible from any device

• A dramatically-improved user experience

• The ability to create, save, and share custom turf nutrition programs

• New product listings (Contec DG® – Gen 3, Foltec® SG, HCU™ – Humic Coated Urea, etc.)
