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.
