Custom Soil Resource Report <br />Canyon <br />A long, deep, narrow valley with high, precipitous walls in an area of high local <br />relief. <br />Capillary water <br />Water held as a film around soil particles and in tiny spaces between particles. <br />Surface tension is the adhesive force that holds capillary water in the soil. <br />Catena <br />A sequence, or "chain," of soils on a landscape that formed in similar kinds of <br />parent material and under similar climatic conditions but that have different <br />characteristics as a result of differences in relief and drainage. <br />Cation <br />An ion carrying a positive charge of electricity. The common soil cations are <br />calcium, potassium, magnesium, sodium, and hydrogen. <br />Cation - exchange capacity <br />The total amount of exchangeable cations that can be held by the soil, expressed <br />in terms of milliequivalents per 100 grams of soil at neutrality (pH 7.0) or at some <br />other stated pH value. The term, as applied to soils, is synonymous with base - <br />exchange capacity but is more precise in meaning. <br />Catsteps <br />See Terracettes. <br />Cement rock <br />Shaly limestone used in the manufacture of cement. <br />Channery soil material <br />Soil material that has, by volume, 15 to 35 percent thin, flat fragments of <br />sandstone, shale, slate, limestone, or schist as much as 6 inches (15 centimeters) <br />along the longest axis. A single piece is called a channer. <br />Chemical treatment <br />Control of unwanted vegetation through the use of chemicals. <br />Chiseling <br />Tillage with an implement having one or more soil - penetrating points that shatter <br />or loosen hard, compacted layers to a depth below normal plow depth. <br />Cirque <br />A steep - walled, semicircular or crescent - shaped, half - bowl -like recess or hollow, <br />commonly situated at the head of a glaciated mountain valley or high on the side <br />of a mountain.
