Sekita Agronomic Trials Update

ThermoPotash trials at Grupo Sekita Agronegocios ('Sekita') provided inconclusive results. Testing conducted by Sekita was implemented in order to compare the agronomic efficiency of granular ThermoPotash with potassium chloride (KCl), on the productivity and quality of carrot crops. Sekita reports: There was no statistical difference in productivity and quality of carrot between treatments using ThermoPotash (TK) and potassium chloride (KCl) and combined application of these two sources, and also compared to the control treatment. With regard to the efficiency of the sources of potassium, the Company expected greater agricultural efficiency from granular ThermoPotash as compared to potassium chloride or the control. However, the release of nutrients from ThermoPotash was observed to be hampered in the field because the granules of the product showed a high degree of hardness and resistance to fragmentation. This decreased the contact and reaction of these particles with the soil preventing the release of total nutrients, thus reducing the efficiency of the product. The Company did not previously observe these characteristics when it supplied ThermoPotash in coarse form as opposed to granules. The company's engineering team expects to resolve this issue by making a simple change to the granulation process.
