Individual Products: (Product composition may differ by country.)

SUPER POTASSIUM® (0-0-40)

SUPER POTASSIUM® complexed with MCT is a concentrated potassium product that is complexed to maximize potassium uptake by plants. SUPER POTASSIUM® promotes internal cellular strength for fruit development and maturity, and regulates the movement of water and nutrients within the plant.

SUPER NITRO® (30-0-0)

SUPER NITRO® with MCT is a complexed nitrogen source that can be applied by foliar application, according to label directions, without the risk of phytotoxicity. It can also be soil applied for nitrogen release while keeping it stable in the root zone. It reduces nitrogen losses from leaching and volatilization. SUPER NITRO® enhances cellular respiration that promotes a longer  productive crop life.

SUPER PHOS® (0-50-0)
(PHOS-MAX™)

SUPER PHOS® complexed with MCT can be applied by foliar application, according to label directions, without the risk of phytotoxicity and keeps phosphate available and soluble in the soil solution for rapid uptake by plant roots without being blocked by clays, metal ions,  or organic matter. Phosphate encourages the production of amino acids, proteins and carbohydrates necessary for cellular division.

38 SPECIAL® (4-14-12 +S)

38 SPECIAL® complexed with MCT is designed for a wide range of uses and can be applied to promote germination, fruiting, and crop vigor. Great as a starter mix.

C-PHOS™ (4-25-0 + 5% Ca)

C-PHOS™ complexed with MCT nourishes crops and corrects calcium and phosphorous deficiencies in a uniquely clear and stable formulation that retains the effectiveness and efficiency of the individual elemental components.

LUCKY 7® (7-7-7 +Mg, S, B, Cu, Fe, Mn, Mo, Zn, Co)

LUCKY 7®  is a broad-spectrum liquid nutrient formulation complexed with MCT. LUCKY 7® is a complete nutrient package containing most macro- and micronutrients. LUCKY 7® provides excellent foliar nutrition, as well as feeding the beneficial biology in the soil. This is a complete nutrient product designed for all types of crops, trees, vines, turf, and ornamentals in a wide range of conditions. It provides an excellent foundation for the maintenance of vigorous growth.

SIL-K®(0-0-10 +5% Si)

SIL-K® complexed with MCT provides the potassium and silica essential in all crops for stronger fruit holding and thicker stems and leaves. It increases the strength and rigidity of the plant cells, resulting in the prevention of premature fruit drop or lodging. It increases fruit quality and shelf life.

Z-PHOS™ (0-12-0 +Zn, Mn, Cu, S)

Z-PHOS™ complexed with MCT enables each nutritional element to be stable and retain effectiveness and efficiency which mixes more readily with other fertilizers. Save time and money by using this preblended formulation.
