6/11/2021 – This is the second fertilization of the Bermuda and centipede sowed around the pond. Below is the evaluation of the areas and a comparison of the soil test report recommendation to ACES’s recommended nitrogen for a low maintenance lawn. Even though it now needs fertilizer it still needs to be mowed at least once per week. It does not need to grow a lot faster.
- Overall – 84,000 = 1.93 ac
- Pond – 170 ft diameter = 13,200 SF
- Grass area = 84,000-13,200= 70,800 SF
Recommendation 1 – The soil test report of January 11, 2021 said to spread 8 lbs/1000 SF of 13-13-13.
- So, 8 x 0.13 = 1.04 lbs of nitrogen per 1000 SF.
- At 8 lbs/1000 SF = 8 x 70.3 = 562 lbs to spread the area.
Recommendation 2 – ACES says here for a low maintenance lawn apply 1/2 lb. nitrogen per 1,000 SF three times per year.
So, the soil test report again has twice the nitrogen of a low maintenance lawn. That is what I found several years ago when evaluating the yard’s fertilizer needs. But, the ACES rate is to be applied three (3) times a year!
- So, to get 0.5 lb nitrogen with 13-13-13 would require spreading per 1,000 sf 0.5/0.13 = 3.86 lbs/1,000 SF.
- At 3.86 lbs/1,000 SF we need to spread 3.86 x 70.8 = 273 lbs. Buy 300 lbs.
- With the spreader set on 3, Fergie running in 1H gear at 540 RPM, we spread the amount of material as planned.
- The Bermuda grass ….. The Centipede did……
