Higher Yields are Available with K-Mag^® Fertilizer

Why K-Mag?
The shortage of just one essential nutrient can shortchange turfgrass yield and quality. Growers can optimize turfgrass productivity by providing a balanced soil fertility program that ensures all 17 essential nutrients are available to plants.

K-Mag fertilizer provides three essential nutrients in the highly available sulfate form. Available in PREMIUM, GRANULAR and STANDARD grades, K-Mag provides 21-22% potassium (K2O), 10.5-11% magnesium (Mg) and 21-22% sulfur (S).

Also known as langbeinite, potassium magnesium sulfate, or double sulfate of potash, K-Mag is sourced from ore beds deep beneath the earth's surface, where an isolated lake of ocean water once existed. Langbeinite, an evaporite mineral, is one of the most soluble salts in the ocean.

Increase turfgrass yields
Proper soil fertility is arguably the most important management practice in improving and maintaining the quality of turfgrass. Providing the right nutrients, at the right rates, at the right times will help promote a dense, medium-to-dark green turf that resists pests, stands up to environmental stresses and improves wear tolerance.

K-Mag provides three essential nutrients needed to produce excellent color, density and yield, and it never affects soil pH.

Potassium (K)
Established turfgrass requires high levels of K. This nutrient enhances root development and branching, improves drought tolerance and cold hardiness by regulating the absorption and retention of water by plants, increases leaf turgor pressure, and reduces the incidence of numerous fungal diseases. Wear tolerance also has been shown to increase proportionally with the plant K levels.

Magnesium (Mg)
Mg puts the green in turfgrass. As the central component of chlorophyll — the pigment molecule responsible for absorbing sunlight during photosynthesis, Mg is responsible for bringing out and maintaining a desirable turfgrass color. Mg also influences phosphorus (P) mobility within the plant, and impacts shoot and root growth (see chart below). Because Mg leeches easily from sandy soils, turfgrass soils in the Southeast commonly test low to deficient in this essential nutrient. K-Mag provides a readily available soluble source of Mg, and it supplies K and Mg in the proper balance.

Sulfur (S)
S is present in certain amino acids, proteins, membranes and coenzymes. S encourages initial root development, which is beneficial to overall turf health, and helps protect against fungal diseases. S deficiencies often result in chlorosis. S shortages are common on sandy soils, and have become more widespread with the reduction in industrial emissions associated with 1990's Clean Air Act.
