This map doesnot presume a specific land use. Rather it portrays the most commonand wide spread attributes that apply to most soil landscapes in theprovince.These maps highlight attributes of soil-landscapes that the landmanager must consider for any intended land use.- Fine texture- Medium texture- Coarse texture- Topography- Wetness- Organic- BedrockF = Fine texture - soil landscapes with fine textured soils (clays andsilty clays), and thus low infiltration and internal permeability rates.These require special considerations to mitigate surface ponding (waterlogging), runoff, and trafficability. Timing and type of tillage practicesused may be restricted.M = Medium texture - soil landscapes with medium to moderatelyfine textures (loams to clay loams), and good water and nutrientretention properties. Good management and cropping practices arerequired to minimize leaching and the risk of erosion.C = Coarse texture - soil landscapes with coarse to very coarsetextured soils (loamy sands, sands and gravels), have a highpermeability throughout the profile, and require special managementpractices related to application of agricultural chemicals, animalwastes, and municipal effluent to protect and sustain the long termquality of the soil and water resources. The risk of soil erosion can beminimized through the use of shelterbelts and maintenance of cropresidues.T = Topography - soil landscapes with slopes greater than 5 % aresteep enough to require special management practices to minimize therisk of erosion.W = Wetness - soil landscapes that have poorly drained soils and/or>50 % wetlands (due to seasonal and annual flooding, surfaceponding, permanent water bodies (sloughs), and/or high water tables),require special management practices to mitigate adverse impact onwater quality, protect subsurface aquifers, and sustain crop productionduring periods of high risk of water logging.O = Organic - soil landscapes with organic soils, requiring specialmanagement considerations of drainage, tillage, and cropping tosustain productivity and minimize subsidence and erosion.R = Bedrock - soil landscapes that have shallow depth to bedrock (
