AB,
Re:
Not all of us expense land,
I know that. I was just pulling CB's chain a little.
But still, the purse may be the dictating factor as to how much fertilizer is used, If any, not a soil test or the local ag folks.
Us old timers look at it this way.
Grass has been growing for thousands of years without mans intervention and will continue to do so long after we are gone.
Now when we fence off a portion of it and run cows on it, it may need a little help sustaining itself. And that is what you should do; give it a little help to sustain it as close to natural as possible.
IMO you should let the grass work for you, not you work for the grass, just like your cattle should work for you and not the other way around.
IMO there is a delicate balance between what grows above the ground and what grows below the ground and any time you fool with that balance you may be asking for trouble and an added expense you don't really need.
Now I don't have a lot of book learnen on it, but it seems to me that sudden bursts of nitrogen to the roots below and/or the stalks above are as harmful to grass as "over grazing" or drought.
Now don't get me wrong, I have nothing against a little fertilizer or lime but if you are trying to make a silk purse out of a sow's ear, I'm again it.
IMO if you learn to play the cards you are dealt, you will have a much better chance of coming out a winner and that goes for your pasture lands too.
