Potatoes have a strict requirement for balanced plant nutrition in order to optimize crop yield and maximize tuber quality by avoiding nutrient deficiencies, nutrient antagonisms in soil and/or in the plant, and increasing tolerance to adverse conditions. Among the major plant nutrients, potassium not only increases yield by improving physiological efficiencies but also enhances various quality aspects such as specific gravity, total solids, sugar and starch content, bruising (mechanical, blackspot), hollow heart, fry quality, and storage.
A balanced fertility program can be accomplished in various ways through preplant, at-planting, foliar, and/or fertigation methods. In regards to potassium, we know from years of research that nutrient demand is highest from early tuber initiation and continues to mid tuber bulking.
NACHURS answer to meet this high potassium demand when the potato plant needs it the most is our “2 & a Q” foliar program.
WHAT IS IT?
Contact a NACHURS representative for specific recommendations on products. It is always recommended that a jar test be done when adding to other fertilizer or chemicals. Always read and follow the pesticide labels when considering tank mixing pesticides with fertilizer products.
