Joe,

When I started down this path Mg% was not the only thing I was watching. I noticed very high H% many places too. Sometimes into the 60+% range. That takes up the space which could be used by other nutrients.

I have posted some examples below from years past of a few of the soil tests from this farm.

My goals are to keep Mg below 15% and Ca above 70%. That naturally kicks off the H. (for my soils).

The last soil test is close to what I like to see.

Edit: Hard to see, even though I darkened the scan. You may need to download to view in a larger format.

Edit 2: The last test.....note the low Mg levels I need to watch now. I have been taking subsoil samples, and there is quite a lot of Mg found below the 6" top sample depth. All the Mg has been "flushed" down the profile so to speak. I will be using K-mag or Maglime  as conditions permit to keep the Mg ppms up. Even with all the low Mg levels, I have only had one low tissue sample out of this particular field.

Edit 3: In the high areas of Mg & H%........note how low the Ca% sometimes is. I hate to see low Ca% , and there are saome in the 20% range!
