RELATIONSHIPS OF YIELD DATA TO AGROCLIMATES, SOIL CAPABILITY CLASSIFICATION AND SOILS OF ALBERTA

Abstract

A method has been devised to relate the yields of wheat, oats and barley to the agroclimatic subregions of Alberta, the soil capability for agriculture and the soils of Alberta, using yield data supplied by the Alberta Hail and Crop Insurance Corporation. Four management practices are included: crops grown on stubble, fallow, stubble-fertilized and fallow-fertilized. Duncan’s multiple range test was used to test the validity of the differences in yields between the agroclimatic subregions, soil capability classes for agriculture, soil series and management practices. This information allowed for the development of economic assessment of a land resource which could be utilized for land evaluation and land use planning.
