The Fertrell Company Super K 3-4-7

The Fertrell Company Super K 3-4-7 is blended to meet the demands of higher phosphorus and potassium requirements by certain crops. It performs much like a combination of Super N 4-2-4 and Gold SS just with higher available potash. The phosphorus helps get germinating seedlings off to good start and the extra potassium helps finish the crop. Super K is also blended with crab meal for nematode control. Available with and without added Boron, Boron and Zinc, and with and without added Sodium Nitrate.
