Let me make a statement that is gonna upset some people, but I wish I had learned it a long time ago. Don't spend one penny on fertilizer, herbicide, seed or anything else until you have correctly sampled your soil and developed a plan to amend it to appropriate levels. If your pH, P and K are not right, even really good grazing management is going to struggle to improve your situation. Allen Williams can do it, but you probably can't. This is for areas where acres/cow is feasible for fertilization.
