According to managing director Dick Holden: "Foliar sprays are not a substitute for soil applied fertiliser, but potassium uptake is not uniform and can reach a peak at critical stages in the crop cycle such as tuber formation."
When the crop is unable to satisfy its instantaneous requirement for potash via root uptake, hbe said, ""timely application of K-Leaf can be hugely beneficial".
A video on the Solufeed website shows how readily K-Leaf can be dissolved in the tank.
