General Terms
Cogeneration
The production of electricity from excess energy produced in a combustion cycle.
G3 Indicator
Sustainability performance indicators contained in the G3 guidelines of the Global Reporting Initiative (GRI), an independent institution whose mission is to develop and disseminate globally applicable sustainability reporting guidelines. The G3 guidelines provide the framework for this report. For more information, visit www.globalreporting.org.
Organizational Culture Diagnostic Instrument®
An employee survey tool developed by safety consulting firm BST that measures factors linked to performance in the areas of environment, safety and health. The results of plant-site OCDI surveys help determine where improvement is needed at the site.
Canpotex Limited
Canpotex is an export company owned by all Saskatchewan potash producers. Sales through Canpotex are generally allocated pro rata to each producer on the basis of productive capacity. In 2006, PotashCorp provided 56% of Canpotex product.
Operating Terms
Capacity
The amount of a given nutrient PotashCorp can produce annually.
Feedstock
A raw material that is used to make products.
Brine
Water containing dissolved potassium and sodium salts, which may be used to carry undissolved salts as a brine slurry.
Measurements
BBtu
One billion British thermal units.
British thermal unit (BTU)
A unit of heat equal to the amount of heat required to raise one pound of water one degree Fahrenheit.
Giga joule (GJ)
One billion joules.
Joule (J)
A unit of energy equal to the amount of work done by a force of one Newton acting through a distance of one meter.
Ton
A short ton. It is the equivalent of 2,000 pounds. Rarely used in Canada since metrication, it is used in the United States. The company's US price lists are in US dollars per short ton. To convert to metric tonnes, multiply by 0.9072.
Tonne
A metric tonne. It is equal to 2,204.6 pounds, or 1,000 kilograms. Most offshore sales are made in metric tonnes and US dollars. To convert to short tons, multiply by 1.1023.
Long Ton
A British measurement, it is 2,240.0 pounds and is used to report sulfur purchases. To convert to metric tonnes, divide by 1.0160.
Megawatt (MW)
One million watts.
Megawatt hour (MWH)
The amount of energy equal to operating a one MW power generator for one hour.
MMBtu
One million British thermal units.
Tera joule (TJ)

One tera joule equals 0.95 BBtus.
Watt (W)
A unit of electric, mechanical or thermal power equal to one joule per second.
Product Terms
Potash
Potassium (K) is the seventh most common element in the earth's crust. Economically recoverable deposits are usually found combined with chlorine in the chemical compound potassium chloride, commonly referred to as potash.
Potash (KCl) fertilizer is muriate of potash (KCl, potassium chloride). Potassium also combines with other materials in specialty fertilizers such as potassium sulfate (K2SO4), potassium magnesium sulfate (K2Mg2(SO4)3) or potassium nitrate (KNO3).
Nitrogen
Nitrogen (N) is a gas which makes up 80 percent of the atmosphere. It is an essential nutrient for plant growth. Some plants, including legumes such as soybeans, can fix nitrogen from the air, but most take it from the soil. It must be applied to soil annually because its nutrient value is consumed during each growing season.
Ammonia (NH3 ) is produced primarily from natural gas and air as the first step in the production of nitrogen fertilizers. It can also be applied directly to soils. Anhydrous ammonia (NH3) is a gas with N-P-K composition 82-0-0, which is changed under pressure to a liquid, and stored and transported in this form.
Ammonium nitrate (NH4NO3), with N-P-K composition 34-0-0, is water-soluble and used as a solid in industrial applications and as a liquid in nitrogen solutions. Half its nitrogen is in ammonium form, half in nitrate form.
Nitric acid (HNO3), produced by an ammonia oxidation process, is used in the production of ammonium nitrate and as an intermediate for industrial purposes.
Nitrogen solutions (UAN) are produced by blending ammonium nitrate and urea solutions. Used in manufacturing starter fertilizers and for direct application on soils, they vary in nitrogen content (28-32%) and are non-pressure solutions.
Urea (CO(NH2)2), N-P-K composition 46-0-0, is the most commonly produced and widely traded nitrogen product. It is used as fertilizer and for industrial purposes.
Phosphate
Phosphorus (P) is widely distributed in nature in combination with other elements. Economically recoverable deposits most commonly contain phosphate rock (apatite), which is used in production of phosphate fertilizers and phosphate chemicals.
DAP, diammonium phosphate, is the major solid phosphate fertilizer. Its excellent handling properties and N-P-K composition 18-46-0 make it well suited to both large- and small-scale agriculture.
MAP, monoammonium phosphate, is a solid fertilizer with a typical N-P-K composition 13-52-0.
P2O5, or Phos Acid, is phosphoric pentoxide, a term used to express content of phosphorus. To convert P to P2O5, multiply by 2.2915.
Dical, Monocal and DFP are animal and poultry feed supplements. They are an important source of phosphate nutrients. They are solid products with differing calcium and phosphate contents. These products are sold on the basis of their phosphorus content.
Emissions Term
NPRI
National Pollutant Release Inventory (Canada)
Safety Terms
Frequency
Number of injuries (recordable or lost-time) multiplied by 200,000, divided by total hours worked.
Lost-time injury
A work-related injury that causes the injured person to be unable to return to work on his/her next scheduled workday after the day of the injury, because he/she is unfit to perform any duties.
Modified work injury
A work-related injury where a Licensed Health Care Provider or the employer recommends that the employee not perform one or more of the routine functions of the job or not work the full workday that the employee would have otherwise worked.
Recordable injury
Medical injury or Modified work injury or Lost-time injury. A medical injury is a work-related injury that is a non-lost-time or non-modified work activity but requires medical treatment beyond first aid.
