Alberta Fertilizer Guide
The purpose of this guide is to provide information on the use of fertilizers under the various cropping and soil-climate conditions throughout the province. Because the nutrient requirements of crops and the ability of soils to supply nutrients vary widely, fertilizer recommendations are given as a range of application rates typical of a particular crop and soil-climatic area. Factors to consider when choosing application rates for specific situations are discussed in the guide. Farmers are encouraged to use the fertilizer guide in conjunction with soil tests and their own experience to develop an effective and economic fertilizer program.
