Product Type
High-potassium fertilizer with humic extracts
RENK
High-potassium fertilizer with humic and fulvic acids for fruit sizing, ripening, sugar accumulation, color, quality and potassium deficiency correction.
RENK is a high-potassium liquid fertilizer with humic and fulvic acids, designed for crop stages with strong potassium demand. Its formulation contains 43% potassium (K₂O) together with a 9% total humic extract, including humic and fulvic acids.
The low-molecular-weight organic acids in the formulation support potassium penetration and translocation within the plant. RENK is particularly suited to fruit development, enlargement and ripening, where potassium is closely linked to sugar transport, uniform maturation, fruit quality and yield.

Key benefits and agronomic effects
- Prevents and corrects potassium deficiencies in crops.
- Supports faster potassium uptake and translocation.
- Promotes fruit development and sizing.
- Supports more homogeneous maturation.
- Helps increase sugar content and fruit oil content.
- Supports crop yield and fruit quality, including color and firmness.
How it works / Technical advantages
RENK combines a high potassium concentration with humic and fulvic acids. The low-molecular-weight organic acids are described as supporting the transport of positively charged ions such as potassium across cellular membranes, helping increase potassium concentration within plant cells.
Potassium complexed with humic acids supports potassium fertilization while also improving the uptake of other essential nutrients. The product is chloride-free and has a density of 1.5 g/cc.
Application rates and timing
Application Guidance: Foliar rate: 300-600 cc/100 L. Fertigation rate: 15-40 L/ha. For fruit-quality programmes, begin from the start of fruit development and repeat at 10-20 day intervals. Application is especially recommended during fruit enlargement and ripening and when color change is desired.
