|  Sul-Po-Mag
Granular is an excellent source
of potassium, magnesium and sulfur for bulk blended fertilizers.
Mined
near Carlsbad,
New Mexico, this naturally-occurring mineral known as langbeinite
has a guaranteed analysis of 22% K20,
11% Mg (18% MgO) and 22% S. Low
Chloride Content
The maximum chloride content of Sul-Po-Mag Granular
is typically below 3.0 percent, minimizing the potential for
fertilizer "burn." Thus, it is widely used on
sensitive vegetable and fruit crops requiring high fertilizer rates, and on
other crops — tobacco, for example — which have a high potassium and magnesium
demand, yet are sensitive to chloride. Non-Acidifying
Sul-Po-Mag Granular is neutral in pH and does not contribute to soil acidity. Totally
Water Soluble
Sul-Po-Mag Granular is totally water soluble; providing potassium, magnesium and
sulfur in a form readily absorbed by plants. Yet, because of its crystalline
nature, Sul-Po-Mag Granular dissolves gradually throughout the growing season, thus
providing a continuous source of nutrients. Replacement
of K, Mg and S
Potassium, magnesium and sulfur are three basic nutrients essential for plant
growth and vital to profitable crop production. They are continually removed
from the soil by high-yield crop production and, in the case of sulfur and
magnesium, are not replaced by many of today's high-analysis fertilizers. All-Natural
Product
As an all-natural fertilizer product, Sul-Po-Mag Granular is approved for use with
organically grown crops. Balanced
Fertilization
Crop producers worldwide have reported extra profit from Sul-Po-Mag when using it
to help balance a good fertility program. Exact monetary benefits from using
Sul-Po-Mag depends on crop, cropping systems, soil type, degree of nutrient deficiencies,
previous cropping methods and climatic conditions during the growing season. AGRONOMIC
CHARACTERISTIC
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. Sul-Po-Mag
