Complesal® Professional SupremeK pro

Complesal® SupremeK pro is a highly concentrated potassium foliar fertilizer for the supplementary nutrition of plants in order to improve the quality of fruits, vegetables and grapes such as fruit size, sugar content, aroma, fruit surface color or brix values in grapes. Low supply to fruits does often occur in light and heavy, K-fixating soils as well during dry conditions. Due to its micronutrient content it is suitable to prevent and eliminate deficiencies. The particular nutrient relationship has a stabilizing effect on plant health.
