For the soils low in micronutrients we have a product to help address that. It is our same blend of Super 13 with the addition of a liquid micronutrient package added to it so you get an even application of micronutrients when you apply the blend. The Super 13 with micros help reduce micronutrient deficiencies that occur in the soil by adding Boron, Copper, Manganese, Molybdenum, and Zinc to your fertilizer application.
