A unique 3-in-1 combination of potassium, magnesium, and sulfur. Premium K-mag granular is totally water soluble: providing potassium, magnesium and sulfur in a form readily absorbed by plants, trees, shrubs and turf. Yet, because of its crystalline nature, K-mag dissolves gradually throughout the growing season, thus providing a continuous source of nutrients. K-Mag is the commercial name for the mineral otherwise known as sulfate of potash-magnesia. It contains 22% soluble potash, 22% sulfur and 11% magnesium. As a quick release source of potassium, K-Mag makes a good addition to soils that lack sulfur. It is virtually 100% water soluble, meaning the palms, trees, shrubs and turf have access to three essential nutrients: Potassium is essential for protein synthesis and protein formation. It improves flavor and color of fruits and vegetables and promotes drought tolerance, hardiness and disease and insect resistance. Magnesium is necessary for optimal plant health. It is the central component of chlorophyll, the pigment molecule responsible for absorbing sunlight during photosynthesis. Sulfur helps to acidify the soil and helps build proteins in plants, trees and turf. Because it is in the sulfate form, it aids root growth and promotes vigorous turf and plant growth. RECOMMENDED USE: for palms, trees, shrubs, turf, ornamental and fruit-bearing trees. We recommend using it in conjunction with our 8-2-12 granular fertilizer for palms that are deficient in potassium and/or magnesium. RECOMMENDED APPLICATION RATE: As a supplement to our 8-2-12 fertilizer, apply 1lb. for every 5lbs. of 8-2-12. As a stand-alone fertilizer, apply 1 lb. of 0-0-22 Premium K-Mag fertilizer per 100 sq.ft. of palm canopy area, flower bed area or landscape area.
