You do not have a rock dilemma.....you have a lack of topsoil building issue. Tillage and picking rocks doesn't address the true issue!
Think about what you see carefully from a different perspective!
Do you have exposed rocks due to topsoil erosion?
And/or do you have exposed rocks because current management isn't building topsoil to cover the rocks!
Likely the answer to both is yes.....so the true issue is one of soil erosion and soil accumulation....exposed rocks are a symptom of bigger issues!
Yes...we have rocks too....some you can see due to erosion and poor soil cover. Pick them if you want.....
....but the situation will never improve because there are many more below those awaiting exposure by soil erosion.
Change landscape management to promote tall forage and you won't be looking at rocks. The deer and the cow will walk around or over rocks or stand on side and eat on the other. Over time, you can build enough topsoil to cover exposed rocks making them invisible! You won't see any rocks in this pic frame unless we burn that area...thus there is no impetus to pick rocks!
