Double K (0-0-25)
High Efficiency Potassium with 1% Kelp and Minors
Double K is a value-added formulation for high potash needs. The
potash is derived from potassium acetate to ensure the maximum
foliar absorption, increasing K+ delivery even under soil conditions
adverse to K+ utilization. Potassium acetate has extreme foliar
uptake without increased risk of phytotoxicity. Double K is sulfur free
and does not cause tip burn or contribute to black layer.
Enhanced stress resistance: Kelp extracts (1%) are added to enhance stress resistance and to encourage root development under stress conditions. Chelated Iron is added to enhance chlorophyll production. The addition of chelated Boron assists in cell wall synthesis and reformation to complement the kelp extracts as they stimulate growth.
Soluble Potash (K2O) 25.0%
Boron (B) 0.02%
Iron (Fe) 0.5%
Derived from: potassium acetate, boric acid, EDTA iron, kelp extracts.
For maintenance use:
3 - 6 oz. / 1,000 sq. ft. every 7 to 14 days
For deficiency rate use:
9 - 15 oz. / 1,000 sq. ft. every 7 days
These charts show the tissue test result 3 days after application of potassium acetate and potassium thiosulfate. With the acetate form, 47% of applied K+ ended up in the leaf tissue. With the thiosulfate form, only 7% of applied K+ ended up in the leaf tissue.
