Item 2. Identity and Background.

     (a) - (c); (f) Yara International ASA (“Yara”) is a public limited liability company organized under the laws of the Kingdom of Norway. The address of its principal executive offices is Bygdøy Allé 2, N-0202, Oslo, Norway. Yara and its consolidated subsidiaries (collectively, the “Yara Group”) are engaged in the production, distribution and sale of nitrogen-based mineral fertilizers and related industrial products. The Yara Group also distributes and sells a wide range of phosphate- and potash-based mineral fertilizers, as well as complex and specialty mineral fertilizer products sourced from third parties.

     (d) and (e) During the last five years, Yara has not been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors), and was not a party to a civil proceeding before a judicial or administrative body of competent jurisdiction as a result of which it was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, United States Federal or state securities laws or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration.

     On March 24, 2004, Norsk Hydro ASA, a public limited liability company organized under the laws of the Kingdom of Norway (“Hydro”) effected a demerger (the “Demerger”) whereby it transferred all assets, rights and liabilities primarily relating to its Agri business to Yara. The transferred assets consisted primarily of shares, partnership interests and other financial interests held by Hydro in companies (including minority interest companies) and partnerships forming the business activities of Hydro Agri. This included Hydro’s 49% indirect equity interest, through its affiliate, Norsk Hydro Holland B.V., a Netherlands corporation (“Hydro Holland”), in Inversiones SQNH S.A., a Chilean closed corporation (“SQNH”), as well as a separate equity interest in Sociedad de Inversiones Pampa Calichera S.A. (“Pampa Calichera”) . SQNH indirectly owns approximately 41.7% of the Series A shares of SQM through its interest in Pampa Calichera. In exchange for Hydro’s transfer to Yara of the assets, rights and liabilities primarily relating to its Agri business, Yara issued to the holders of Hydro shares one of Yara’s shares for each Hydro share outstanding on the date the Demerger was completed. The Yara shares issued in the Demerger represented 80% of Yara’s total outstanding shares at the time of the completion of the Demerger.

     In accordance with the terms of the Demerger, Hydro Holland’s interest in SQNH was transferred to Yara Nederland B.V., a member of the Yara Group, on September 15, 2004.

     On October 22, 2004, Yara Nederland B.V. sold 2.2% of the shares held directly in Pampa Calichera to Inversiones SQ Holding S.A. “(“SQH”), which holds the remaining 51% interest in SQNH not held by Yara Nederland BV. This transaction did not alter the amount of Yara’s indirect equity interest in the Series A shares of SQM.

Item 4. Purpose of Transaction.
