Here's the spreader calibration chart that I referenced. Looking at the chart you will see SGN. SGN is the size of the particle of the product you're putting out. generally fertilizers are 200 to 250 SGN lime products are 140 to 155 SGN and insecticide and fungicide products are generally 95 to 100 SGN. This should get you close to the correct setting . It's a PDF so you can print and save www.advancedturf.com/wp-content/uploads/2024/05/ats-granular-fertilizer-guide.pdf
It is. Most of research $$ that turf has is a very small fraction of what is available. Understandably it primarily goes into crop science/food production. Generally high pH soils does not reduce yield on those crops so there is not much study that goes into high pH correction. It's why it is hard to find good information on lowering pH. Also, I would like to know more about centipede turf. It seems to have a bit of a cult following within the turf world. It is not put on golf courses so my experience with it is not where I would like it to be. I likely done more research on it than any other grass I talk about. Mostly it's all the same but centipede has its unique needs that are interesting.
What are your thoughts on dissolving some baking soda in water and spraying on lawn to raise PH? There was a little known UA-camr that did this dissolving 3 tablespoons of baking soda per gallon of water and spraying, my concern was the amount of sodium in baking soda
There are a ton of hacks out there that are goofy. Without doing the math my guess you wound need a lot of baking soda to lower the pH. So much so there wound be a chance you could damage the turf. 3 tbsp presumably over 1000ft would not do a thing for pH. Not enough alkalinity going out on the soil. Its why I ONLY take advise from University research. Outside of that waist time, money and damage the lawn.
Here is one I have. I have found it to be accurate. Just be careful to not to push it in from the top. Being plastic it can crack. Hold it by the metal probe when putting it into the ground. Pd ad amzn.to/4dIMlXu
Great video! Just one question. I have high magnesium according to my soil test. I have gone to my big box store now a few times and the only calcitic lime that I can find is “sta-green fast acting lime” is fast acting lime, different than normal lime?
I just notice that’s the same stuff you have in the video! If I follow the label on the bag for the amount per thousand square feet. It’s not even close to the 40 pounds my soil test recommended. Would it be OK to use the 40 pounds per thousand square feet using that same product. Do you have in your video?

Thanks Greg. You put out some great videos. I can see your channel growing quick here soon.
Thanks!!! Appreciate the kind words

Centipede lawns need that low pH. It's hard to find good information and amounts.

Hi Greg, great video! Can you post that spreader calibration chart you referenced?
Ooos.. will put it here and in the comments. www.advancedturf.com/wp-content/uploads/2024/05/ats-granular-fertilizer-guide.pdf

Greg, you briefly mention ph soil probe. I've been looking on Amazon, any recommendations? Thanks!

@@GregPhillips.22that’s funny I bought that one yesterday waiting for it to be delivered. How do you like it?
@@SeahawkAzit worked well. Ike's the quick and I think the readings where accurate

It's just a marketing thing. Just about all pelletized lime products act the same.
It's why soil tests are needed. I don't know why they put recommended rates on a lime bag.
Use the Dr Soil brand from Lowe’s
Best time of year to add lime for zone 9a Florida?😊❤
Lime it really does not matter so much. Only frozen ground limits lime aps. This time of year is best for soil tests.
High Ph soils are not just out west. I live in southwest OH very near IN and my Ph is almost 8
In my research I did find there were high pH soils in your area.
PH of 2.5 is battery acid
It's actually on an old mine site that produces acid mine drainage.
