    14    TYPE OF REPORTING PERSON
          CO

Item 1.  Security and Issuer.
------   -------------------

         This statement relates to shares of Series A Common Stock, no par value
("Series A Shares"), of Sociedad Quimica 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 Miraflores 222, Piso 11, Casilla
96-D, Santiago 290, Chile.

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 Saskatchewan, Canada, is 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 122 - 1st Avenue South, Saskatoon, Saskatchewan, Canada S7K 7G3.

         (2) Inversiones El Boldo Limitada ("Chile Holdco") is a limited
liability partnership formed under the laws of Chile for the purpose of
acquiring shares of the Issuer, and its principal business address is Avenida
Apoquindo 3721, Piso 12, Santiago, Chile. PCS indirectly beneficially owns
the entire equity interest in Chile Holdco and, as a result, ownership of the
Series A Shares owned by Chile Holdco is deemed to be shared with PCS.

         The names, addresses, occupations and citizenship of the directors and
executive officers of PCS and of the executive officers of Chile Holdco are set
forth in Schedule I attached hereto.

         Neither of the Reporting Persons nor, to the best of their knowledge,
any of the persons listed in Schedule I has, during the last five years, been
convicted in a criminal proceeding (excluding traffic violations or similar
misdemeanors) or 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.
------   -------------------------------------------------

         The total amount of funds (excluding applicable brokerage commissions)
utilized by Chile Holdco to acquire the Series A Shares beneficially owned by
the Reporting Persons was approximately 91.7 billion Chilean pesos or
approximately U.S.$129 million. Chile Holdco obtained all of such funds from
PCS, and PCS provided such funds from a combination of cash on hand and
borrowings pursuant to its general operating credit facility. PCS intends to
refinance such borrowings with the proceeds of borrowings under its existing
commercial paper program.

Item 4.  Purpose of Transaction.
------   ----------------------

         Between October 24 and 26, 2001, Chile Holdco purchased a total of
48,270,406 Series A Shares. All of such Series A Shares were purchased in a
public auction transaction or in open market transactions, in each case on the
Bolsa de Comercio de Santiago, Bolsa de Valores (the Santiago Stock Exchange).
The Series A Shares beneficially owned by the Reporting Persons were acquired by
them as a strategic investment in a company active in complementary markets.

         Subject to any applicable limitations under relevant laws or
regulations or under the Issuer's constituent documents, the Reporting Persons
may in the future acquire additional Series A Shares, or other equity securities
of the Issuer, in the open market, in privately-negotiated purchases, through a
public tender offer or otherwise. The Reporting Persons may also, depending on
then current circumstances, dispose of all or a portion of the Series A Shares
beneficially owned by them in one or more transactions. Additionally, the
Reporting Persons understand that the rules applicable to elections of directors
of the Issuer (similar to "cumulative voting") should currently, in view of the
number of Series A Shares held by the Reporting Persons, permit the Reporting
Persons to elect at least two directors of the Issuer at any meeting of
shareholders of the Issuer at which directors are to be elected. The Reporting
Persons intend to exercise their voting rights with respect to the Series A
Shares beneficially owned by them.

         Except as set forth in this statement, neither of the Reporting Persons
currently has any plans or proposals that relate to or that would result in any
of the actions or transactions described in paragraphs (a) through (j) of Item 4
of the instructions to Schedule 13D. However, the Reporting Persons reserve the
right from time to time to formulate plans or proposals regarding the Issuer or
any of its securities and to carry out any of the actions or transactions
described in paragraphs (a) through (j) of Item 4 of the instructions to
Schedule 13D, to the extent deemed advisable by the Reporting Persons.

Item 5.  Interest in Securities of the Issuer.
------   ------------------------------------

         (a) The Reporting Persons share beneficial ownership of the following
Series A Shares:

              Number of Series A                     % of All Equity Securities
                    Shares         % of Class(1)              of Issuer(2)
              ------------------ ------------------       ------------------

PCS...........     48,270,406         33.8%                     18.3%
Chile Holdco..     48,270,406         33.8%                     18.3%

(1) Based upon 142,819,552 Series A Shares outstanding as of September 28, 2001.
(2) Based upon 142,819,552 Series A Shares and 120,376,972 shares of Series
    B Common Stock, no par value, of the Issuer outstanding as of
    September 28, 2001.

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

         (c) Other than the transactions described in Schedule II of this
statement, neither of the Reporting Persons nor, to the best of their knowledge,
any of the persons listed in Schedule I, have effected any transactions in
Series A Shares during the 60-day period preceding the date this statement was
filed.

         (d) Because PCS indirectly beneficially owns all of the outstanding
voting equity securities of Chile Holdco, PCS may be deemed to have the right to
receive, or the power to direct the receipt of dividends from, or the proceeds
of the sale of, any Series A Shares owned by Chile Holdco. Except as disclosed
herein, no person other than the Reporting Persons has any right to receive or
the power to direct the receipt of dividends from, or the proceeds of the sale
of any of the Series A Shares owned by the Reporting Persons.

         (e) Not applicable.

Item 6.  Contracts, Arrangements, Understandings or Relationships With Respect
------   to Securities of the Issuer.
         ---------------------------

         Other than as described in Item 3 of this statement, there are no
contracts, arrangements, understandings or relationships (legal or otherwise)
among the Reporting Persons or, to the best of their knowledge, any of the
persons listed in Schedule I, or between such persons and any other person with
respect to any securities of the Issuer, including but not limited to transfer
or voting of any of such securities, finder's fees, joint ventures, loan or
option arrangements, puts or calls, guarantees of profits, division of profits
or loss, or the giving or withholding of proxies.

Item 7.  Material to be Filed as Exhibits.
------   --------------------------------

         None.

                                   SIGNATURES

         After reasonable inquiry, and to the best of my knowledge and belief, I
certify that the information set forth in this statement is true, complete and
correct.
