Cotton - Intrepid Potash

FAQ

Q
What is Intrepid Trio?

A
Intrepid Trio is natural langbeinite, a unique mineral with three essential nutrients comprised of 21.5-22% potassium (K₂O), 10.5-10.8% magnesium (Mg) and 21-22% sulfur (S) as sulfates, depending on grade.
Q
When should Intrepid Trio be applied?

A
Intrepid Trio should be split applied with half prior to planting and half at time of first square as part of a side dress application.
Q
When and how does the cotton plant use potassium (K₂O)?

A
The majority of potassium uptake takes place from the first bloom to the end of the flowering period. During the flowering period, uptake rates range from 2.2 to 3.5 lb K₂O / acre / day. Potassium is then rapidly translocated from the leaves and stems to the burr of the boll during boll fill. The potassium in Intrepid Trio is immediately available to the cotton plant for flowering and boll development.

Potassium also increases water use efficiency of the cotton plant, activates enzymes within the plant and serves as a regulator nutrient, and helps the plant to resist crop diseases and pests.

Q
How can magnesium (Mg) help the cotton plant?

A
Magnesium is an essential component of the chlorophyll molecule which is integral in the photosynthesis process that allows the plant to convert sunlight to energy. Magnesium also supports plant growth and function through enzyme activation and acting as a phosphorous carrier, aiding in the plant’s ability to take up phosphorous.

Magnesium deficiency on sandy, acidic soils can be caused by the application of heavy potassium fertilizer rates without magnesium. The deficiency causes older cotton leaves to turn a purplish color between the veins. Soils with high acidity and high annual rainfall respond best to a readily available magnesium fertilizer like Intrepid Trio.
Q
How does the sulfur (S) in Intrepid Trio benefit cotton?

A
Sulfur aids the cotton plant by enhancing plant height and number of vegetative branches, while a sulfur deficiency leads to a stunted cotton plant. The sulfur in sulfate form as found in Intrepid Trio is the only form of sulfur readily available to plants. Sulfate-sulfur does not have to go through the oxidation process like elemental sulfur – thus pH is not decreased by the resulting release of hydrogen into the soil.
Q
When will Intrepid Trio be available to the cotton plant?

A
Intrepid Trio readily dissolves in soil slowly, making it 100% available to the plant and reducing the risk of leaching. Intrepid Trio is available in granular and standard grades. The granular grade mixes and blends well with other fertilizer materials for an even distribution of nutrients.
Q
Is Intrepid Trio available in multiple grades?

A
Available in premium, granular and standard grades, Intrepid Trio blends well with other fertilizer materials for an even distribution of nutrients.
