1 Super soluble potassium sulphate for modern agriculture Focus on potatoes K-LEAF focus on pots 1

2 Why Potassium? Physiological Water regulation (turgor) Protein synthesis Photosynthesis Diseases/disorders Disease resistance (eg Alternaria) Frost tolerance Lodging Yield and quality Significant contributor to yield (T/ha) Flower production Tuber development K-LEAF focus on pots 2

3 Why foliar application of Potassium sulphate? (FPS) Management of potassium Improves uptake of soil-applied K Enables precise matching of K fertilization to crop needs Risk mitigation Improved crop profitability Significant yield increases Quality improvements Environmental considerations Chlorine EC K-LEAF focus on pots 3

4 But... Traditional SOP products are very slow to dissolve so very difficult to use! So. K-LEAF focus on pots 4

5 Why K-LEAF? K-Leaf is 3x more soluble than the very best existing SOP formulation! Therefore truly suitable for modern spraying machines K-LEAF focus on pots 5
