Summary
Nitrogen, phosphorus and potassium get a lot of attention, but there are other nutrients that are just as important for soil and plant health. In this week’s interview, we talk with Gregg Forster of Wisconsin Mineral Solutions about some of those other nutrients, including the role of calcium as the “truck” that helps move other nutrients in the plant, the role of boron as the “wheels” on the truck, and the role calcium plays in improving soil texture. But like most things in life there can be too much of a good thing, so we also talk about how much calcium is too much.
