The finished granular potash product is transferred to on-site warehouses/large silos, where different grades of potash are stored separately. Granular potash results from compaction of the finely ground material and has very regular size and shape. The granular potash is stored in large domes that can reach 50m (165 ft) in diameter, making accurate measurement of the dome’s contents very difficult. This lack of reliable measurement impacts operators' inventory management and control capabilities.
