 You know, if you haven't done a soil test in a while, you may want to do that. Sometimes, and not usually in Kansas, but sometimes we can get a little low on potassium or our pH gets to where we can't take some of that up. Potassium is a good element that really helps. Would that be between a 3.5 and a 7? Okay, Jason, I think he was asking about the pH content of the percentage there, numbers.
