Sure-K® has a long track record of success in both row and horticultural crop applications.

Sure-KYears of replicated research at both the largest plant nutrition research farm in the country, and in field trials across North America have proven that recommended applications of Sure-K® can increase yield with less applied fertilizer than its conventional counterparts.

Why Sure-K®?
