We have been given our rates to be used in our GenNext Complete A & B fertilizer. The date of our first application will be dependent on the weather. Here are the rates that we will be using on 2 acres of greens which will equate to approximately 11 greens (practice green, 1-9, 10, 17).
March 29 ~ 16 oz./m application of A & B (11 gallons of each)
April 12 ~ 16 oz./m application of A & B (11 gallons of each)
April 24 ~ 8 oz./m application of A & B (5.5 gallons of each)
May 8 ~ 8 oz./m application of A & B (5.5 gallons of each)
After our initial application we are told that we should see any turf voids or thin turf fill in quickly. After the second application we should see the poa annua stop out competing the bentgrass, creating a very smooth putting surface the entire day. After the third application we will use our soil moisture meter to start monitoring moisture levels as the product has some features that allow molecules of water to adhere to the roots meaning we could start to reduce irrigation needs. We will be marking a spot on each green that will not receive Complete A & B to monitor and compare for poa annua reduction as the process is very gradual and hard to detect day to day. We will be taking pictures of the spots and we will be told how to treat the photo electronically to identify the poa annua. We do have a moss problem on some of our greens and hope that we can see a reduction in the moss with the Complete A & B products along with other cultural and chemical controls.
We are told the 8 oz. per 1000 sq. ft. rate is the rate that moves poa annua out at about a 15 to 20% rate on a yearly basis. If we reduce the rate you get the effects of the even putting turf and enhanced coloration but your poa reduction is minimized.
We are excited to try this product out and hope to see the results that are being advertised by GenNext.
