When adding lime in the soil, can you have too much? Perhaps the most frequently asked question by those using our soil fertility program is, “Can I put on a higher rate of lime than you are recommending for this sample?”
Generally, this has to do with getting the limestone spread, because the owner of the lime trucks says he either cannot or will not apply such a small amount. Many times a farmer has been told, “You can’t use too much lime.”
That is not true. From our experience in working with thousands of acres that have previously been over-limed, we know you can easily apply too much lime, not just on crops such as berries and potatoes, but on whatever crop you are intending to grow. And if this happens, it can be far more expensive than just the cost of the extra limestone that was not needed, with the added cost of getting it spread.
