DISCLOSURE CONTROLS AND PROCEDURES



|A. | Certifications
|-- | --------------

The required disclosure is included in Exhibits 99.10 -
99.13 to this Annual Report on Form 40-F.



|B. | Evaluation of Disclosure Controls and Procedures
|-- | ------------------------------------------------

Agrium Inc. (the
Registrant) maintains disclosure controls and procedures and internal control over financial reporting designed to ensure that information required to be disclosed in the Registrants filings under the Securities Exchange Act of
1934, as amended (the Exchange Act) is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission (the SEC). The Registrants Chief
Executive Officer (CEO) and Chief Financial Officer (CFO), after having evaluated the effectiveness of the Registrants disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of
the end of the period covered by this report have concluded that, as of such date, the Registrants disclosure controls and procedures were effective to ensure that information required to be disclosed by the Registrant in reports that the
Registrant files or submits under the Exchange Act is (i) recorded, processed, summarized and reported, within the time periods specified in the SECs rules and forms, and (ii) accumulated and communicated to management, including its
principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. However, as recommended by the SEC in its adopting release, the Registrant will
continue to periodically evaluate its disclosure controls and procedures and will make modifications from time to time as deemed necessary to ensure that information is recorded, processed, summarized and reported within the time periods specified
in the SECs rules and forms.

The Registrants disclosure controls and procedures are designed to provide
reasonable assurance of achieving their objectives and, as indicated in the preceding paragraph, the CEO and CFO believe that the Registrants disclosure controls and procedures are effective at that reasonable assurance level, although the CEO
and CFO do not expect that the disclosure controls and procedures or internal control over financial reporting will prevent all errors and fraud. A control system, no matter how well conceived or operated, can provide only reasonable, not absolute,
assurance that the objectives of the control system are met.

|C. | Managements Annual Report on Internal Control Over Financial Reporting
|-- | -----------------------------------------------------------------------

The required disclosure is included in the Managements Report that accompanies the Registrants
Consolidated Financial Statements for fiscal year ended December 31, 2015, filed as part of this Annual Report on Form 40-F.



|D. | Attestation Report of the Independent Registered Public Accounting Firm
|-- | -----------------------------------------------------------------------

The required disclosure is included in the Report of Independent Registered Public Accounting Firm that accompanies
the Registrants Consolidated Financial Statements for the fiscal year ended December 31, 2015, filed as part of this Annual Report on Form 40-F. See Controls & Procedures in Managements Discussion and Analysis
for the fiscal year ended December 31, 2015 filed as part of this Annual Report on Form 40-F.



|E. | Changes in Internal Control Over Financial Reporting
|-- | ----------------------------------------------------

Except as
disclosed in Managements Discussion and Analysis for the fiscal year ended December 31, 2015, there was no change in the Registrants internal control over financial reporting that occurred during the period covered by this report
that has materially affected, or is reasonably likely to materially affect, its internal control over financial reporting.

AUDIT
COMMITTEE FINANCIAL EXPERT

The Registrants Board of Directors has determined that it has at least one audit committee
financial expert (as such term is defined in paragraph 8(b) of General Instruction B to Form 40-F) serving on its Audit Committee. Mr. Victor J. Zaleschuk has been determined to be such audit committee financial expert and is
independent (as such term is defined in the New York Stock Exchanges corporate governance standards).

Paragraph 8(d) of
General Instruction B to Form 40-F indicates that the designation of an individual as an audit committee financial expert does not make him an expert for any purpose, impose on him any duties, obligations or liability that are greater
than the duties, obligations or liability imposed on him as a member of the Audit Committee and the Board of Directors in absence of such designation, or affect the duties, obligations or liability of any other member of the Audit Committee or Board
of Directors.



---

CODE OF ETHICS

The Registrant has adopted a code of ethics (as that term is defined in Form 40-F), entitled Code of Business Conduct and Ethics
that applies to all directors, officers and employees of the Registrant. The Code of Business Conduct and Ethics has been posted on the Registrants website and may be viewed by visiting www.agrium.com and selecting the Governance
Documents tab within the section entitled Governance.

The Code of Ethics is available in print to any shareholder who
requests it. Requests for copies of the Code of Ethics should be made by contacting the Registrant in writing at 13131 Lake Fraser Drive S.E., Calgary, AB T2J 7E8, by telephone at (403) 225-7000, or on the Registrants website at
www.agrium.com.

In the past fiscal year, there have not been any amendments to the Code of Ethics or waivers, including implicit
waivers, from any provision of the Code of Ethics.

AUDIT COMMITTEES PRE-APPROVAL POLICIES AND PROCEDURES

The Registrant has adopted a written policy pursuant to which the Registrants Audit Committee pre-approves all audit services and
permitted non-audit services provided to the Registrant by the Registrants independent auditors. The pre-approved services specified in such policy are reviewed annually, and the audit and non-audit services to be provided by the
Registrants independent auditors, as well as the budgeted amounts for such services, are also pre-approved annually. The Audit Committee has also delegated to the Chair of the Audit Committee, who is independent, the authority to act on behalf
of the Audit Committee with respect to the pre-approval of all audit and permitted non-audit services provided by its external auditors from time to time. Any approvals by the Chair are reported to the full Audit Committee at its next meeting. None
of the services described in footnotes 2 and 3 under Principal Accountant Fees and Services above were approved by the Audit Committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of
Regulation S-X.

OFF-BALANCE SHEET ARRANGEMENTS

The required disclosure is included on page 62 of Managements Discussion and Analysis for the fiscal year ended December 31, 2015,
filed as part of this Annual Report on Form 40-F and in note 11 to the Registrants audited annual financial statements included as Exhibit 99.3 of this Annual Report on Form 40-F.

TABULAR DISCLOSURE OF CONTRACTUAL OBLIGATIONS

The required disclosure is included on page 59 of Managements Discussion and Analysis for the fiscal year ended December 31, 2015,
filed as part of this Annual Report on Form 40-F.

IDENTIFICATION OF THE AUDIT COMMITTEE

The Registrant has a separately-designated standing audit committee established in accordance with section 3(a)(58)(A) of the Exchange Act.
The members of the Audit Committee are Russell J. Horner (Chair), David C. Everitt, A. Anne McLellan, Derek G. Pannell and Victor J. Zaleschuk.

RESERVE AND RESOURCE ESTIMATES

The Registrants mineral reserves have been estimated in accordance with National Instrument 43-101 -Standards of Disclosure for
Mineral Projects (NI 43-101), as required by Canadian securities regulatory authorities. For United States reporting purposes, Industry Guide 7 under the Securities Act of 1933, as amended, as interpreted by the Staff of the SEC,
applies different standards in order to classify mineralization as a reserve. In addition, while the terms measured, indicated and inferred mineral resource are required pursuant to NI 43-101, the SEC does not
recognize such terms. Canadian standards differ significantly from the requirements of the SEC, and mineral resource information contained in the documents incorporated into this Annual Report on Form 40-F by reference is not comparable to similar
information regarding mineral reserves disclosed in accordance with the requirements of the SEC. Investors should understand that inferred mineral resources have a great amount of uncertainty as to their existence and great uncertainty
as to their economic and legal feasibility. In addition, investors are cautioned not to assume that any part or all of our mineral resources constitute or will be converted into reserves.

MINE SAFETY DISCLOSURE

The information concerning mine safety violations or other regulatory matters required by Section 1503(a) of the Dodd-Frank Wall Street
Reform and Consumer Protection Act and Item 16 of General Instruction B to Form 40-F is included in Exhibit 99.9 to this Annual Report on Form 40-F.

|B. | Consent to Service of Process
