Sure-K® is a clean, chloride- and hydroxide-free potassium solution.  It can be applied in combination with other crop production or protection products and presents a very low risk of crop injury. Sure-K® can be used in any cropping situation where potassium is needed. Sure-K®’s unique formula provides increased crop utilization, allowing lower total product application volume to produce the same results as other conventional potassium fertility products when applied at typical rates.
