Just for reference, farmers near here used to grow sugar beets for several years on alkaline soil, since they seem to play well with it (think literally white in places). After a few years, the minerals causing the alkaline are reduced or depleted and they move to other crops. I don't know if the solution to alkaline soil came from adding acid type products to the soil, or if the beets consumed the minerals, but it might be worth looking into.

The sugar beets are, surprise, processed into sugar. You’ve likely used some of it (e.g., U&I (Utah and Idaho), C&H (Chicago and Hawaii)). The leavings from the process is sugar lime. It can be seen in huge mounds that some parts of the states would, literally, call hills. This is applied to fields by the ton.
