The goal of a Maxand Program is to uniformly incorporate Maxand into the rootzone. Short of renovating your greens, the best way to achieve a responsive level of Maxand in your rootzone is by including Maxand in your topdressing after aerifying and in routine topdressing.
Maxand is best applied with topdressing but the benefits to turf extend well beyond normal topdressing. Maxand provides multiple benefits to the quality and health of fine turfgrasses. Greens recover faster from aerification and verticutting, minimizing the negative revenue impact from these necessary cultural practices. The enhanced quality of the turf and reduced management headaches are the net gain.
Incorporating Maxand into the rootzone- This photograph provides a clear example of how quickly fresh topdressing material accumulates at the top of the rootzone.The plug was taken from a green that had included in the topdressing program black-dyed USGA spec sand during winter months over two successive winters to help hold heat on the surface of the green.Following USGA guidelines for application of topdressing on Ultradwarf greens will result in an accumulation of more than ½” of fresh topdressing in the top of the rootzone each year.
The photo also illustrates the importance of including Maxand with each topdressing application. Omitting Maxand from an application will result in a layer of topdressing material that impedes Maxand’s beneficial properties of moisture management, nutrient retention and improved pesticide efficacy.
Annual Maxand Topdressing Results
The following are results of a survey of Superintendents using the Maxand Program for the past 12 months.
- Enhanced Soil Moisture Management. All of the superintendents monitor the moisture in the root zones of their greens on a daily basis. Each superintendent reported a significant increase in moisture retention and uniformity. There were no reports of excess moisture. Some reported improved firmness.
- Watering requirements were reduced during dry season. Localized Dry Spots (LDS) were dramatically reduced or eliminated completely. Applications of wetting agents for treatment of LDS were reduced or eliminated.
- Hand-Watering was reduced or eliminated. Prior to incorporating Maxand into the rootzone of their greens, Superintendents reported hand-watering requirements of 1½ – 2 hours per day per 18-hole course. Hand-watering was reduced by not less than 60%, averaging 80% reduction and in some cases completely eliminated. Reduction or elimination of this practice allowed for a more productive use of skilled labor.
- Increased Nutrient Holding Capacity. All of the superintendents tested soil and plant tissue as part of their nutrient programs. Soil tests showed improved Base Saturation. This response is consistent with field studies. CEC increased with Maxand in the soil profile. Some of the superintendents modified their fertilization program, reducing their fertilization application rates based on the improved soil and tissue tests.
- Faster Recovery from cultural practices such as aerification and verticutting. Superintendents report a more rapid recovery after aerification. Greens returned to a playable condition sooner. Players also returned to the course sooner, positively impacting Golf and Food and Beverage revenues.
- Enchanced Plant Health / Improved root response. All of the superintendents reported improved root growth. Some of the improvements were quite dramatic. Maxand’s nutrient holding capacity and moisture management benefits reduced plant stress and enhanced plant health. The result is evident in the improved root structure.
- Cost-Efficient. Each superintendent found Maxand to be cost-efficient. The cost offset provided by labor savings or labor reallocation was equivalent to more than half of the cost of the Maxand Program. The reduction of other input costs – wetting agents, nutrients and pesticides – as well as improved revenue stream to the golf course contributed to the cost-efficiency. In most cases, the financial benefits of the Maxand Program more than paid the cost of the Program.
