Using Maxand

New or Renovated Greens

Maxand reduces the grow-in period of sprigged or seeded turfgrass by several weeks when installed in the soil profile of new or renovated greens. Reducing the time it takes to establish new turfgrass results in cost savings and revenue enhancement. Cost savings are also realized because of Maxand’s ability to manage moisture and hold nutrients. The volume of water required for grow-in water is reduced. The amount of nutrients required during grow-in is reduced because Maxand retains and releases nutrients efficiently. The cost of maintenance during grow-in is reduced as wash-outs during heavy rainfall are minimized and the turfgrass is established more quickly. The same beneficial properties that accelerate the grow-in process remain in the rootzone, providing faster recovery from routine maintenance like aerating and verticutting. Reducing the time to reach complete playability means greater revenue. Research and Field Studies have shown Maxand’s ability to reduce the grow-in period by more than one-third. Re-opening renovated greens three weeks to one month sooner means golf revenues that were once included as a part of the project cost are now where they belong—on the income statement.

Recommended Application Rate

For maximum effectiveness, EVTI recommends a root-zone mix containing 20% Maxand. Significant benefits can be achieved with slightly lower rates of Maxand and possibly some peat in the root zone mix. When considering the cost of Maxand, it is important to remember that Maxand’s cost-savings and quality improvement benefits extend well beyond the grow-in period. The quality of the turfgrass will be greater and the cost to maintain that quality will be lower.

Recommended Application Method

Given the depth of the typical root systems of ultradwarf turfgrasses it may be unnecessary to include Maxand in the entire depth of the rootzone. A rootzone blend containing Maxand can be installed in the top four to six inches of the rootzone by applying a layer of Maxand on the top of the rootzone mix and tilling it using a rototiller. Since Maxand is coated USGA spec sand, it blends quickly, easily and uniformly.

Existing Greens

Core Aerification

Maxand can be introduced into the root zone of existing greens through the routine maintenance practices of aeration and topdressing. Each core aeration removes approximately 5% of the organic material (assuming 1/2” tines at 2” spacing). Replacing the cored material with sand amended with Maxand begins the process of converting the entire root zone with a more beneficial blend of sand and Maxand. Even though only 5% of the greens’ surface is affected, results from having Maxand in the rootzone will soon be evident. The recovery period from core aeration using Maxand in the topdressing mix is cut virtually in half.

Accelerated Installation

The most intensive program for installing Maxand in the rootzone is a combination of both of the methods mentioned above. The combination of core and solid-tine aeration, routine topdressing and the Dryject method can convert up to 30% of the rootzone from sand to a
more beneficial sand-Maxand mix over a one-year period.


EVTI installed Maxand using the DryJect method through Florida Soil Solutions* in studies at the University of Florida Research and Education Center in Davie, FL and on golf course greens and fairways. The DryJect method proved to install a greater volume and dispersion of Maxand in the rootzone when compared to traditional aeration methods.

Recommended Application Rate

Installing Maxand in existing greens requires nothing more than including Maxand in the topdressing mix for all routine maintenance practices. Application rates are the same as the rates for new or renovated greens, between 10% and 20%, with 20% Maxand the optimal amount.
