Tobacco removes more potassium than any other nutrient with 90 lbs/K per acre considered the minimum annual application needed and most growers using anywhere between 90 and 150 lb/ac. Potassium serves as a regulator nutrient that aids in photosynthesis, improves water use efficiency of the plant through regulation of stomatal openings, and helps the plants resist disease and pests.
Chloride toxicity is a major problem in tobacco with fertilizer rates of higher than 30 lbs/ac of Cl causing toxicity to the plant. Tobacco as a result of Cl toxicity will have poor smoke flavor along with a decrease in leaf yields and quality. As an example, muriate of potash applied at 90 lbs/ac would supply 50 lbs K and 41 lbs Cl which is above the Cl limit. Soil fumigants that are commonly used in tobacco production can also add anywhere from 10-15 lbs/Cl per acre.
Intrepid Trio® is the perfect source of K fertilizer as it contains less than 2% Cl and can be safely used for production of high quality tobacco.
