Oslo-Yara International ASA reports that during the second quarter it will continue the planned maintenance outage of its Nordic NPK facilities. The continuance will reduce NPK production by approximately 200,000 mt and calcium nitrate by approximately 50,000 mt. Yara said the planned maintenance stops are extended in order to reduce inventories to minimum levels at the end of the fertilizer season. The prolonged stops will take place at Yara’s plants in Porsgrunn and Glomfjord in Norway, and at Uusikaupunki and Siilinjärvi in Finland.
