The foliar application of Potassium Nitrate in Citrus has been studied for many years. The tests done over time comproved that the Citrus is one of the most responsive crops to K fertilization, including via foliar. The benefits of K fertilization are also well known, as such as the increase in yield and in quality of the fruits, the increase of fruit size and the decrease of creasing, fruit cracking and fruit dropping. Haifa has several products designed for foliar nutrition of the Citrus. This post presents a foliar nutrition program designed for K nutrition of Citrus orchards in production (6 years old and beyond).
