CLI is the classification of climate and soil capability for the production of common field crops (corn, soybeans, small grains, forages) . In the CLI rating system there are seven classes: Class Descriptions: Class 1 No significant limitations in use for Crops Class 2 moderate limitations on use for crops Class 3 moderately severe limitations on use for crops. Class 4 Severe limitations on use for crops. Class 5 Very severe limitations preclude annual cultivation; improvements feasible. Class 6 Natural grazing only; no improvements feasible. Class 7 No capability for agriculture. O Organics ? not rated W Water ? not rated Classifying Prime and Marginal Agricultural Soils and Landscapes: Guidelines for the Application of the Canada Land Inventory in Ontario http://www.omafra.gov.on.ca/english/landuse/classify.htm Prime agricultural areas include specialty crop areas and areas where prime agricultural land (Canada Land Inventory [CLI] Classes 1 to 3) predominates. While mainly comprised of CLI Classes 1 to 3 lands, prime agricultural areas may also include associated smaller pockets of poorer-capability lands (Classes 4 to 7) and additional areas with a local concentration of farms.(http://www.omafra.gov.on.ca/english/landuse/prime-ag-areas.htm)DRAINAGE1 Indicates classification of how well the soil drains. Drainage Classes - Not Applicable VR Very Rapidly R Rapidly W Well MW Moderately Well I Imperfectly P Poorly VP Very Poorly WA Water VA Variable DR_DESIGN1 The drainage design code reflects the source of the drainage water problem and the soil drainage characteristics. DR_DESIGN Description S1 Overall fine texture. Poor development, soils becomes more compact with depth. S2 Overall medium texture and well structured. Soil becomes more compact with depth. Free water saturation at depths less than 1 meter on parent material. S3 Overall medium to coarse texture. Sola are deeper than S2. Free water saturation at depth less than 1 metre on II C. S4 Overall medium to coarse texture, with fine textured ?B? horizon that may impede internal drainage. S5 A bog-like depressional soil. The surface layer is organic. S6 Shallow soil over bedrock. G1 Soils developed on loam, silt loam and stratified by ponding. Seasonal free water saturation in relation to perched groundwater. G2 Outwash sands, more than 1 metre deep over clay till or lacustrine clay. Seasonal free water saturation in relation to perched groundwater. G3 Deep coarse textured soils with seasonal free water saturation in relation to regional groundwater. HYDRO1 Hydrologic Soil Groups are used to estimate runoff from precipitation. Classification of soils by their reference to intake rate of infiltration of water, which is influenced by texture, organic matter content, stability of the soil aggregates and soil horizon development. Soils are assigned to one of four groups. They are grouped according to the infiltration of water when the soils are thoroughly saturated. Class Description A Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. B Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. C Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. D Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have high shrink-swell potential, soils that have a permanent high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. Chisholm P. S. 1981. Hydrological Classification of Ontario Soils.

Soil texture is determined by the relative proportion of sand, silt and clay found in a given soil. The term "texture" refers to the size of the individual soil particles and has nothing to do with the amount of organic matter present in the soil.

Phases are subdivisions of soils used to indicate external characteristics that are normally not considered a characteristic of the soil in question. The modifier may be comprised of more than one phase codes. The absence of a modifier will be indicated by three underscore characters (i.e. ) The modifiers and their descriptions are listed below: Phase Description NO PHASE PRESENT B BOULDERY PHASE C COARSE PHASE D DUNE PHASE E ERODED PHASE F FINE PHASE G GRAVELLY PHASE H HEAVY CLAY PHASE I IMPERFECTLY DRAINED PHASE K CALCAREOUS PHASE L LOAMY PHASE O PEATY PHASE Q COBBLY PHASE R RED PHASE S STEEP PHASE T TILL PHASE U ROLLING PHASE V VERY SHALLOW PHASE W WASHED PHASE X ROCKY PHASE Y COMPACTED PHASE Z STONY PHASE _BR BROWN PHASE _HR HEAVY RED PHASE _KL CALCAREOUS LOAMY PHASE _LR LOAMY RED PHASE _LY LOAMY COMPACTED PHASE _RU RUBBLY PHASE _RW RED WASHED PHASE _SH SHALLOW PHASE _SS SAND SPOT PHASE _TR TILL RED PHASE RSS RED SAND SPOT PHASE
