Trio Sul-Po-Mag 0-0-22 22% S, 11% Mg

This is an organic, granular sulfate of potash-magnesia, sul-po-mag (also known as Kmag, or by the mineral name langbeinite) product with 22% potassium, 22% sulfur (as sulfate), and 11% magnesium. This is a great product if you need potassium and magnesium. It is a more readily available form of potassium than potassium sulfate and slower acting form of magnesium than magnesium sulfate (epsom salt). This product should be used mainly to feed the crop over a season and should be thought of less as a soil mineral balancer (it will add a bit to the potassium and magnesium on a soil test, but is not the most efficient way to build those levels).
Always check with your organic certifier before using any product.
