    Any thoughts on correcting PH with lime or other methods. Calcium carbonate vs. dolomitic? Organic guys/gals what are your thoughts?

    We try and get most of our customers to take a soil test. If the ph is 6.5 we apply lime. If the pH is 7.5 then we apply sulfur. For soil conditioning we also apply gypsum and compost. The soil around here is natuarally alkiline from the glaciers.

    Which type of lime is determined by calcium/magnesium ratio in soil test.

    I thought a pH of 6.5 - 7 is where you want to be?

    Reason I ask is because I had a thread on pH here last spring on my pH was 6.5 and everyone told me that was great don't do anything.

    ArTurf,
    Any time that the state does a soil test for us, the results all come back with the same mumbo-jumbo. Use XX amount of dolomitic limestone. Calcium/Magnesium blend.

    So is sulfur what you put down to reduce the pH?

    I made a small bo bo and we'll, should had done something different in this area to start with but I now have honeysuckles (acidic plant) and Holly (Also acidic) planted along my fence line. What I did wrong was also plant grass (Alkaline) right up to the fence hence you now see the bo bo. I'm fixing to correct that this summer so I want to make the soil there acidic.

    Same here, I've actually got to the point I know what my lawn needs without tests. Last time I got soil samples was last June, was told to put Nitrogen down :hammerhead:

    I got 40 or 50 lb bags from our suppliers. I found on the internet this site:

    Half of my suppliers say gypsum does not change pH and the other half says it does...so I dont know. They all said sulfur will lower and lime will rasie your pH. We put HydroSave from NatraTurf on as many lawns as we can, they also have spot gone for pets (same product smaller bag and sgn):

    If you look on there they talk about soil samples too. Its best to be taking annual samples, at least untill you get it between 6-7.5.
