1 <br />' Co16y sill loam soils have slopes ranging from rr to =i: <br />soils, forrned in a flood-deposition environment, e::l-~i <br />drained sail profiles, ~neadium to rapid water percolatio <br />as well as tf,e properties; listed as common between affe <br />' types. ~ higl-r susceptibility to wind erosion is of p <br />concern with regard to topsoils within this category o <br />However, the surface layer- typically of these soils has <br />' through flood scouring. <br />Colby silt loam soils ma~:e~ up a portion of the loamy pla <br />' site for F~rowers County.

In combination, these soil traits lead to art: <br />draughty soils, largely ran suited for agricultural use. <br />' t}re Colby silt loam soils, the topsoils typical of the <br />and Havre series are very susceptible 'to wind erosion. <br />the absence of typical sail layers in this locale E <br />erosion as ~; val:id reeiamextion concern. <br />The Glendive and Havre soils-sand substrata are constituf <br />of the sandy bottomland range type.
