KEYTERRA CAOS 3-0-20

NK FERTILIZER SOLUTION – EC FERTILIZER

Potassium, after nitrogen, is the second element most needed by plants. KEYTERRA CAOS 3-0-20 contains high amounts of potassium together with supporting nitrogen, and it is enriched with organic and carboxylic acids as well as amino-acid complexes that enhance uptake. Potassium plays a key role in plant metabolism: sugar and protein synthesis, transport of photosynthates, and activation of enzymes. Plants especially need potassium in the final stages to fill out their fruits, and adequate potassium improves cold resistance.

Thanks to its carboxylic-acid content, the product breaks down lime layers in the soil and has strong cation-retention (complexing) capacity. When metal salts locked in the soil are freed by carboxylic acids, they become available for root absorption and the soil structure improves while adding organic matter. This accelerates fertilizer uptake, boosts productivity, and promotes healthy plant growth.

Regular use of KEYTERRA CAOS 3-0-20 forms stronger plant tissues and supports pigment formation responsible for color, while also enhancing aroma. Applied especially during fruit-ripening, it secures maximum and homogeneous coloration and extends shelf-life by improving fruit firmness.

In tomatoes and strawberries, poor coloration near the calyx can be corrected by applying KEYTERRA CAOS 3-0-20 when color change starts.
