Keeping the greens (and all the other areas of the course) green and growing during the winter is a tricky job. Convincing grass that would normally take it easy for the winter to keep growing takes some special ingredients.
We have talked about some of the fertilizers that we use and the philosophy in the past. The method of application is also interesting. We use a nozzle made by FCI (Rainmaker) that we have calibrated to apply 11 gallons of mix per 1,000 square feet. That is important so that we know how much nitrogen or other ingredients we are really applying to the turf. The application may look hap hazard or unsophisticated but it is really a great way to insure proper over lap without tire marks or doubling up of rates on the over lapped areas. Also, it is a great way to get the fertilizer to interact with the soil, thatch and plant tissue all in the same application without the need to apply water through the sprinkler heads after the application.
Applicator "raining" the fertilizer
This method is good for the environment because the fertilizer lands and stays where we want it. The need for irrigation to be run after an application is removed as is the chance that the fertilizer will be washed to a concentrated area or washed away from the intended sight. Sometimes "old school" methods are still the best. It certainly works for us.
