Soil Test Question
Recently got my results. Potassium 296 ppm, Magnesium 352 ppm. Both way above optimum. Any suggestions how to lower these? This area is used exclusively to grow tomatoes.
Wayne County Michigan
There is no real need to lower the levels of potassium and magnesium. The problems are created when there is a deficiency of those nutrients in the soil. As long as the soil pH is in a good range, the plant will uptake the nutrients it needs without a problem.
