I have fields that grow good corn but alfalfa does not produce good or stay productive over three years. Would this field be better for grass?
If alfalfa is not doing well, I would suggest a complete soil audit (A complete soil test can be done for $12.50) to help in determining why this piece of land is not producing. Many of the highly digestible grasses will not do well on fields that are lacking in calcium or other minerals. You most likely will be disappointed in the results. Many times a couple of tons of high calcium lime plus manure will help greatly.
