RM of Westbourne Bulletin 99-36 - Agriculture and Agri-Food Canada

Page 16 Information Bulletin 99-36 Rural Municipality of WestbourneAgricultural Capability Map.This evaluation utilizes the 7 class Canada Land Inventory system(CLI, 1965). Classes 1 to 3 represent the prime agricultural land,class 4 land is marginal for sustained cultivation, class 5 land iscapable of perennial forages and improvement is feasible, class 6land is capable of producing native forages and pasture butimprovement is not feasible, and class 7 land is consideredunsuitable for dryland agriculture. Subclass modifers includestructure and/or permeability (D), erosion (E), inundation (I),moisture limitation (M), salinity (N), stoniness (P), consolidatedbedrock (R), topography (T), excess water (W) and cumulativeminor adverse characteristics (X).This generalized interpretive map is based on the dominant soilseries and phases for each soil polygon. The CLI subclasslimitations cannot be portrayed at this generalized map scale.Table 5.
