ous materials . Soil reaction ranges from slightly acidic in thesurface horizons to moderately alkaline in the subsoil . <strong>The</strong> soilclassification is usually Gleyed Brunisolic Gray BrownLuvisol .Soil Moisture Characteristics Berrien soils are imperfectlydrained . <strong>The</strong> s<strong>and</strong>y surface materials are rapidly permeable,but have relatively low water-holding capacity, <strong>and</strong> arepotentially droughty during the summer months . <strong>The</strong> underlyingclayey materials are moderately to slowly permeable which<strong>of</strong>ten leads to perched water table conditions <strong>of</strong> variable durationat the s<strong>and</strong>-clay interface. Surface run<strong>of</strong>f from Berriensoils is slow because <strong>of</strong> its slowly permeable subsoil <strong>and</strong> nearlylevel topography.Commonly Associated <strong>Soils</strong> Bookton (BOO) <strong>and</strong> Wauseon(WUS) soils are most commonly associated with Berriensoils in map units BRR 4 <strong>and</strong> BRR 5 . <strong>The</strong>ir parent materialsare similar to those <strong>of</strong> Berrien soils but their drainages differ.<strong>Soils</strong> <strong>of</strong> the Muriel catena may occur in proximity to Berriensoils where the s<strong>and</strong>y veneer thins to less than 40 cm as in mapunit BRR 21 .L<strong>and</strong> Use <strong>and</strong> Management Berrien soils are importantagricultural soils used extensively for grain corn, beans,tobacco <strong>and</strong> specialized horticultural crops . <strong>The</strong>y have slightsoil fertility <strong>and</strong> soil moisture deficiencies which can be significantto agricultural use or management . Under intensive <strong>and</strong>continuous row crops, structural degradation <strong>of</strong> the surfacehorizon <strong>and</strong> loss <strong>of</strong> organic matter can readily occur, whichexacerbates these inherent soil limitations .Beverly <strong>Soils</strong> (BVY)General Soil Description Beverly soils have developedon lacustrine silty clay loam <strong>and</strong> silty clay deposits . <strong>The</strong>y areimperfectly drained .Surface Ap horizons <strong>of</strong> Beverly soils consist <strong>of</strong> approximately15-20 cm <strong>of</strong> siltyclayloam . <strong>The</strong>y are moderatelyhigh inorganic matter, ranging between 5-6 016 . Surface horizons arenormally underlain by about 40 cm <strong>of</strong> B horizon <strong>of</strong> silty clayloam or silty clay textures . <strong>The</strong>se subsoil horizons are frequentlyvery firm <strong>and</strong> compacted, <strong>and</strong> are prominently mottled. Strongly calcareous Ck horizons begin at about 60-70 cmdepth . <strong>The</strong>y are normally silty clay loam in texture <strong>and</strong> areprominently layered with alternating silty <strong>and</strong> clayey varves.Soil reaction ranges from near neutral at the surface to moderatelyalkaline in the subsoil . Soil classification is usually GleyedBrunisolicGray Brown Luvisol .Soil Moisture Characteristics Beverly soils are imperfectlydrained . <strong>The</strong>y are moderately to slowly permeable.Groundwater temporarily occupies the surface horizons eachyear. <strong>The</strong> saturation period is normally medium, but may beprolonged in some instances where frequent use <strong>of</strong> heavymachinery has caused compaction <strong>of</strong> the subsoil . <strong>The</strong> waterholdingcapacity ranges from medium to high, <strong>and</strong> surfacerun<strong>of</strong>f is medium .Commonly Associated <strong>Soils</strong> <strong>Brant</strong>ford (BFO) <strong>and</strong>Toledo (TLD) soils are most commonly associated withBeverly soils in map units BVY 6 <strong>and</strong> BVY 8 . <strong>The</strong>y differ fromBeverly soils, being moderately well-drained <strong>and</strong> poorlydrained, respectively.L<strong>and</strong> Use <strong>and</strong> Management Beverly soils are importantagricultural soils <strong>and</strong> their dominant use is for grain corn,small grains <strong>and</strong> forage crops . <strong>The</strong>y are also used to a lesserextent for specialized crops such as soybeans, sweet corn <strong>and</strong>tomatoes . Tile drainage is usually required to extend the growingseason <strong>and</strong> to facilitate harvesting operations. <strong>The</strong>se soilsare susceptible to compaction by heavy machinery when operationsare carried out during wet soil conditions .Bookton <strong>Soils</strong> (BOO)General Soil Description Bookton soils have developedon s<strong>and</strong>y lacustrine veneer 40-100 cm thick overlying clayeylacustrine or glacial till deposits . <strong>The</strong>y are well-drained soils .Surface Ah horizons <strong>of</strong> Bookton soils usually consist <strong>of</strong>20-25 cm <strong>of</strong> fine s<strong>and</strong>y loam . <strong>The</strong>y are underlain by 20-30 cm<strong>of</strong> loamy s<strong>and</strong> B horizons over the clayey subsoil . Bt horizonsoccur at the interface with this heavy-textured material at adepth <strong>of</strong>40-50 cm . <strong>The</strong>y are generally silty clay loam in texture<strong>and</strong> very firm <strong>and</strong> compacted . Relatively unaltered clayey subsoil,comprising IICk horizons, occurs between 70-80 cmdepth . <strong>The</strong>y are strongly calcareous <strong>and</strong> extremely firm <strong>and</strong>compacted . Soil reaction ranges from near neutral in surfacehorizons to moderately alkaline in the subsoil . Soil classificationis usually Brunisolic Gray Brown Luvisol .Soil Moisture Characteristics Bookton soils are welldrained. <strong>The</strong> s<strong>and</strong>y surface materials are rapidly permeable,but the underlying clayey material is moderately to slowly permeable. Temporary perched water table conditions may occurat this s<strong>and</strong>-clay interface. Surface s<strong>and</strong>s have low waterholdingcapacity<strong>and</strong> are commonly droughty during dry summerconditions . Surface run<strong>of</strong>f is slow on level or gentlysloping Bookton soils, but increases on moderate <strong>and</strong> steepslopes .Commonly Associated <strong>Soils</strong> Berrien (BRR) soils aremost commonly associated with Bookton soils in map unitsBOO 3, <strong>and</strong> Wauseon (WUS) soils may occur as inclusions .<strong>The</strong>ir parent materials are similar to Bookton soils, but theirdrainage differs . Fox (FOX) <strong>and</strong> Brady (BAY) soils also arecommon associates <strong>of</strong> Bookton soils in map units BOO 7 <strong>and</strong>BOO 19 respectively, as subdominant components <strong>of</strong> thesemap units . In these instances, the s<strong>and</strong>y veneer occasionallyexceeds 100 cm in depth .L<strong>and</strong> Use <strong>and</strong> Management Bookton soils are importantagricultural soils for a wide range <strong>of</strong> crops including graincorn, hay, winter wheat, spring grain, <strong>and</strong> specialized cropssuch as tobacco <strong>and</strong> horticultural crops . <strong>The</strong>y have slight soilfertility <strong>and</strong> soil moisture deficiencies which can be significantto l<strong>and</strong> use <strong>and</strong> management . Supplemental irrigation may benecessary for some crops .Brady <strong>Soils</strong> (BAY)General Soil Description Brady soils have developed onglaciolacustrine sediments consisting <strong>of</strong> s<strong>and</strong> <strong>and</strong> loamy s<strong>and</strong>textures usually modified on the surface by wind action. <strong>The</strong>yare imperfectly drained soils .Surface Ah horizons <strong>of</strong> Brady soils usually consist <strong>of</strong> 15-20 cm <strong>of</strong>loamys<strong>and</strong> or s<strong>and</strong>y loam . <strong>The</strong>y are relatively high inorganic matter with contents <strong>of</strong> 5-6 01o . <strong>The</strong> underlying B horizons are 30-40 cm thick, usually <strong>of</strong> loamy s<strong>and</strong> texture <strong>and</strong>with prominent mottles . Strongly calcareous Ck horizons usuallybegin at 50-60 cm depth <strong>and</strong> are s<strong>and</strong> or loamy s<strong>and</strong> texture. Soil reaction ranges from neutral in the surface horizonsto moderately alkaline in the subsoil . Soil classification istypically Gleyed Brunisolic GrayBrown Luvisol .
