High
Performance Fertilizer
K-Mag® GRANULAR supplies three
vital plant nutrients — potassium, magnesium and sulfur
(22% K20, 11% Mg and 22% S). It is a naturally-occurring
crystalline mineral which can be direct applied or used as
a raw material in bulk blend fertilizers. It is an excellent
source of non-chloride potassium, water soluble magnesium
and non-acidifying sulfur. K-Mag GRANULAR provides an economical
source of magnesium and sulfur to produce custom bulk blend
fertilizers.
Its maximum chloride content is less than 2.5 percent, minimizing
the potential for fertilizer "burn." It is widely
used on sensitive vegetable and fruit crops that require
high fertilization rates, but do not tolerate high levels
of chloride or soluble salts. K-Mag GRANULAR has a typical
SGN of 250 and is often used as a source of potassium, magnesium
and sulfur in bulk blend formulas (NPK+Mg+S).
Agronomics
Potassium is required for the uptake of nitrogen and synthesis
of protein and starch. It also helps activate more than sixty
enzymes, making them available to stimulate other chemical
processes within the plant. Adequate potassium is essential
for fruit formation, optimum yields and high quality.
Magnesium activates a large number of enzymes in the plant and is
also required for the synthesis of chlorophyll — the vital
green pigment necessary for sugar manufacturing in plants.
Sulfur activates a number of enzymes, is vital to the formation
of amino acids, is crucial in the production of protein
and is especially important to plants with high oil content.
