Fox soils are susceptible to wind erosion.Planting cover crops, establishing windbreaks, <strong>and</strong>carrying out management .practices whichmaintain organic matter levels, will aid inreducing the risk <strong>of</strong> erosion by wind .Conservation tillage practices, particularly no-tillpractices, should be considered for these soils .Frome <strong>Soils</strong> (FR)L<strong>and</strong>form <strong>and</strong> TopographyFrome soils have developed on blankets <strong>of</strong>coarse textured lacustrine materials . <strong>The</strong>y occur indepressional positions in l<strong>and</strong>scapes which havenearly level topography. Slopes are less than 2% .Soil Moisture CharacteristicsFrome soils are very poorly drained <strong>and</strong>rapidly permeable . Saturated conditions occur ator near the surface for long periods each year dueto high water table levels. <strong>The</strong>y have low waterholding capacities <strong>and</strong> surface run<strong>of</strong>f is slow .General Soil Characteristics<strong>The</strong> Ap horizons usually have s<strong>and</strong>y loam orloamy s<strong>and</strong> textures. <strong>The</strong> Bg <strong>and</strong> calcareous Ckghorizons tend to have higher s<strong>and</strong> contents <strong>and</strong>s<strong>and</strong> or loamy s<strong>and</strong> textures.Bluish gray to gray gley colours are dominantwithin the pr<strong>of</strong>ile. Soil reaction ranges fromneutral in the surface Ap horizons, to mildlyalkaline in the Ckg horizons . Soil classification istypically Orthic Hun-dc Gleysol .Soil VariabilityFrome peaty phase (FR.P) soils were mappedwhere 15 to 40 cm <strong>of</strong> organic materials overly thes<strong>and</strong>y materials. <strong>The</strong> aerial extent <strong>of</strong> Frome <strong>and</strong>Frome peaty phase soils in the <strong>County</strong> is limited .L<strong>and</strong> Use/Management CommentsFrome <strong>and</strong>Frome peaty phase soils require tiledrainage in order to reach their potentialcapability for common field crop production.Frome soils are rated Class 3W, <strong>and</strong> Frome peatyphase soils are rated Class 4W . Due to theextreme wetness conditions associated with thesesoils, they are either not suitable or they havelimited suitability for special crops . Suitabilityincreases for some special crops, however, if theyare tile drained. Suitability ratings for selectedspecial crops are given in Tables 6, 7, <strong>and</strong> 8.Gobles <strong>Soils</strong> (GO)L<strong>and</strong>form <strong>and</strong> TopographyGobles soils have developed on fine to veryfine textured morainal materials which arecommonly referred to as Port Stanley till. <strong>The</strong>yoccur on ground <strong>and</strong> terminal moraines whichcommonly have nearly level to gently undulatingtopography. Occasionally they also occur inl<strong>and</strong>scapes which are hummocky or rolling.Slopes generally range from 1 to 9%, but slopes <strong>of</strong>6% or less are most common.Soil Moisture CharacteristicsGobles soils are imperfectly drained <strong>and</strong>moderately to slowly permeable. Saturatedconditions occur in the upper horizons for briefperiods each . year . Gobles soils have high waterholding capacities, <strong>and</strong> moderate to rapid surfacerun<strong>of</strong>f.General Soil CharacteristicsGobles soil materials contain 27% or more clay.<strong>The</strong> Ap horizons frequently have silty day loamor clay loam textures, but silty day or claytextures are also common. <strong>The</strong> Bmgj, Btgj, <strong>and</strong>calcareous Ckgj horizons which commonly occurusually have silty clay loam or silty clay textures .Occasionally the texture <strong>of</strong> the subsoil horizonsmaybe clay loam or clay.Distinct to prominent, yellowish brown toreddish brown mottles occur within the pr<strong>of</strong>ile .Soil reaction ranges from slightly acid to neutral inthe Ap horizons, to mildly alkaline in the Ckgjhorizons. Soil classification is typically GleyedBrunisolic Gray Brown Luvisol.Soil VariabilityLocalized areas <strong>of</strong> severely eroded Gobles soilsoccur in some l<strong>and</strong>scapes, primarily those whichhave surface slopes that are greater than 5% .Occasionally surface stones occur whichmayaffecttillage or harvesting operations .Gobles soils frequently occur where thinsurface caps <strong>of</strong> medium or coarse texturedmaterials overly the morainal materials . Goblesloamy phase (GO.L) soils were mapped where 15to 40 cm <strong>of</strong> silt loam or loam textured materialsoccurred at the surface . Gobles coarse phase(GO.C) soils were mapped where 15 to 40 cm <strong>of</strong>fine s<strong>and</strong>y loam or s<strong>and</strong>y loam textured materialsoccurred at the surface. Gobles washed phase(GON) soils were mapped where 40 to 100 cm <strong>of</strong>silt loam or loam textured, lacustrine modified tillmaterials overly clayey till materials.
