CUSIP No. 833635105 / 833636103	Schedule 13D	Page 6 of 16

Item 1. Security and Issuer.

This Amendment No. 8 amends the Schedule 13D, dated November 2, 2001, as amended (the “Schedule 13D”), of Potash Corporation of Saskatchewan Inc. and Inversiones El Boldo Limitada, with respect to Series A Shares and Series B Shares, of Sociedad Química y Minera de Chile S.A. (the “Issuer”), a company organized under the laws of the Republic of Chile. The principal executive offices of the Issuer are located at El Trovador 4285, Piso 6, Santiago, Chile. Capitalized terms used but not otherwise defined in this Amendment have the meanings ascribed to such terms in the Schedule 13D.

Item 2. Identity and Background.

This statement is filed pursuant to Rule 13d-2(a) under the Securities Exchange Act of 1934, as amended, by the persons listed below (the “Reporting Persons”).

(1) Potash Corporation of Saskatchewan Inc. (“PCS”), a corporation organized under the laws of Canada, is (together with its subsidiaries) an integrated fertilizer and related industrial and feed products company engaged in the production of potash, phosphate and nitrogen products. The principal business address of PCS is Suite 500, 122 — 1 ^st Avenue South, Saskatoon, Saskatchewan, Canada S7K 7G3.

(2) PCS Chile II LLC (“Chile II”) is a limited liability company organized under the laws of Delaware principally for the purpose of acquiring and holding shares of the Issuer, and its principal business address is: Suite 400, 1101 Skokie Blvd., Northbrook, Illinois 60062. PCS indirectly beneficially owns the entire equity interest in Chile II and, as a result, ownership of the Series B Shares owned by Chile II is deemed to be shared with PCS.

(3) Inversiones El Boldo Limitada (“Chile Holdco”) is a limited liability company formed under the laws of Chile principally for the purpose of acquiring and holding shares of the Issuer, and its principal business address is Avenida Apoquindo 3721, Piso 12, Santiago, Chile. PCS, through its ownership of Chile II and another entity, indirectly beneficially owns the entire equity interest in Chile Holdco; Chile II indirectly owns 99.98% of Chile Holdco. As a result, ownership of the Series A Shares and Series B Shares owned by Chile Holdco is deemed to be shared with PCS and Chile II.

(4) Inversiones RAC Chile Limitada (“RAC”) is a limited liability company formed under the laws of Chile and was acquired by PCS principally for the purpose of acquiring and holding shares of the Issuer, and its principal address is: Avenida Apoquindo 3721, Piso 12, Santiago, Chile. PCS indirectly beneficially owns the entire equity interest in RAC and, as a result, ownership of the Series A Shares and the Series B Shares owned by RAC is deemed to be shared with PCS.


CUSIP No. 833636105 / 833635103	Schedule 13D	Page 7 of 16

None of the Reporting Persons, during the last five years, have been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or have been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, Federal or State securities laws or finding any violation with respect to such laws.

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

In transactions occurring on December 26, 2006 and December 27, 2006, Chile Holdco purchased a total of 2,231,254 Series B Shares for an aggregate purchase price of Ch$15,968,534,959. All of such Series B Shares were purchased in open market transactions on the Bolsa de Comercio de Santiago, Bolsa de Valores (the Santiago Stock Exchange). Chile Holdco obtained such funds from capital contributed by its immediate parent. The capital contributed by Chile Holdco’s immediate parent originated from PCS from its cash on hand.

Item 4. Purpose of Transaction.

Chile Holdco purchased the Series B Shares to increase PCS’s indirect combined ownership in SQM for investment purposes. The acquisition by Chile Holdco of the Series B Shares does not materially affect the Reporting Persons’ control rights over SQM. The Series B Shares have limited voting rights (holders of Series B Shares elect one of eight members of the Board of Directors (the “Series B Director”) and vote together with the Series A Shares on other matters), and the Reporting Persons’ increased ownership of Series B Shares from 14.30% to 16.15% does not materially increase their influence over the election of the Series B Director and their increased ownership, on a combined basis, of Series A and Series B Shares from 30.50% to 31.35% does not materially increase their voting power with respect to other matters.

Each of the Reporting Persons intends to review its investment in SQM on a regular basis and, as a result thereof, may at any time or from time to time determine, (a) to acquire additional securities of SQM through open market purchases, privately negotiated transactions or otherwise, (b) to dispose of all or a portion of the securities of SQM owned by it in the open market, in privately negotiated transactions, in one or more registered public offerings or otherwise, or (c) to take any other available course of action with respect to SQM or its securities. Notwithstanding anything contained herein, each of the Reporting Persons specifically reserves the right to change its intention with respect to any or all of such matters. In reaching any decision as to its course of action (as well as to the specific elements thereof), each of the Reporting Persons currently expects that it would take into consideration a variety of factors, including, but not limited to, the following: SQM’s business and prospects; other developments concerning SQM and its business generally; other business opportunities available to the Reporting Persons; changes in law and government regulations; general economic conditions; and financial and stock market conditions, including the market price of the Series A and Series B Shares.

Except as set forth in this Item 4, the Reporting Persons have no present plans or proposals that relate to, or that would result in, any of the actions specified in clauses (a) through (j) of Schedule 13D of the Exchange Act.

Item 5. Interest in Securities of the Issuer.

(a) The Series A Shares and Series B Shares beneficially owned by each of PCS, Chile II, Chile Holdco and RAC are as follows:


	Number of					Number of						% of All Equity
	Series A Shares		% of Class⁽¹⁾			Series B Shares			% of Class⁽²⁾			Securities of Issuer⁽³⁾
PCS		63,062,037		44.16	%		19,444,156	⁽⁴⁾		16.15	%		31.35	%
Chile II		43,861,795		30.71	%		16,744,383	⁽⁴⁾		13.91	%		23.03	%
Chile Holdco		43,861,795		30.71	%		10,658,383			8.85	%		20.71	%
RAC		19,200,242		13.44	%		2,699,773			2.24	%		8.32	%


(1)		Based upon 142,819,552 Series A Shares outstanding as of December 31, 2005 (as reported in the Issuer’s Form 20-F filed with the Commission on June 30, 2006).

(2)		Based upon 120,376,972 Series B Shares outstanding as of December 31, 2005 (as reported on the Issuer’s Form 20-F filed with the Commission on June 30, 2006).

(3)		Based upon 142,819,552 Series A Shares and 120,376,972 Series B Shares of the Issuer outstanding as of December 31, 2005.

(4)		Chile II and PCS beneficially own 6,086,000 Series B Shares in the form of American Depositary Receipts, each representing 10 Series B Shares.

(b) Because PCS indirectly beneficially owns the entire outstanding equity interest in Chile Holdco and RAC, PCS may also be deemed to have the power to vote or to direct the voting or to dispose or direct the disposition of all of the Series A Shares and all of the Series B Shares owned by Chile Holdco and


CUSIP No. 833635105 / 833636103	Schedule 13D	Page 8 of 16

RAC. Because Chile II indirectly owns 99.98% of the outstanding equity interest of Chile Holdco, Chile II may also be deemed to have the power to vote or to direct the voting or to dispose or direct the disposition of all of the Series A Shares and the Series B Shares owned by Chile Holdco. Except as otherwise disclosed herein, no person other than the Reporting Persons shares the power to vote or to direct the vote or to dispose or direct the disposition of any of the Series A Shares or the Series B Shares owned by the Reporting Persons.

(c) None of PCS, Chile II, RAC or Chile Holdco has effected any transactions in Series A Shares since the most recent amendment to the Reporting Persons’ Schedule 13D filed on December 26, 2006 (“Amendment No. 7”). The table below sets forth information with respect to all transactions in Series B Shares effected by PCS, Chile II, RAC or Chile Holdco since Amendment No. 7 was filed. All of such Series B Shares were purchased for cash by Chile Holdco in open market transactions on the Bolsa de Comercio de Santiago, Bolsa de Valores (the Santiago Stock Exchange).
