Complex slope <br />Irregular or variable slope. Planning or establishing terraces, diversions, and <br />other water-control structures on a complex slope is difficult. <br />Complex, soil <br />A map unit of two or more kinds of soil or miscellaneous areas in such an <br />intricate pattern or so small in area that it is not practical to map them <br />separately at the selected scale of mapping. The pattern and proportion of the <br />soils or miscellaneous areas are somewhat similar in all areas. <br />Concretions <br />See Redoximorphic features. <br />Conglomerate <br />A coarse grained, clastic sedimentary rock composed of rounded or subangular <br />rock fragments more than 2 millimeters in diameter. It commonly has a matrix of <br />sand and finer textured material. Conglomerate is the consolidated equivalent <br />of gravel. <br />Conservation cropping system <br />Growing crops in combination with needed cultural and management practices. <br />In a good conservation cropping system, the soil-improving crops and practices <br />more than offset the effects of the soil-depleting crops and practices. Cropping <br />systems are needed on all tilled soils. Soil-improving practices in a conservation <br />cropping system include the use of rotations that contain grasses and legumes <br />and the return of crop residue to the soil. Other practices include the use of <br />green manure crops of grasses and legumes, proper tillage, adequate <br />fertilization, and weed and pest control. <br />Conservation tillage <br />A tillage system that does not invert the soil and that leaves a protective amount <br />of crop residue on the surface throughout the year. <br />Consistence, soil <br />Refers to the degree of cohesion and adhesion of soil material and its <br />resistance to deformation when ruptured. Consistence includes resistance of <br />soil material to rupture and to penetration; plasticity, toughness, and stickiness <br />of puddled soil material; and the manner in which the soil material behaves <br />when subject to compression. Terms describing consistence are defined in the <br />“Soil Survey Manual.” <br />Contour stripcropping <br />Growing crops in strips that follow the contour. Strips of grass or close-growing <br />crops are alternated with strips of clean-tilled crops or summer fallow. <br />Control section <br />The part of the soil on which classification is based. The thickness varies <br />among different kinds of soil, but for many it is that part of the soil profile <br />between depths of 10 inches and 40 or 80 inches. <br />Custom Soil Resource Report <br />32 Index #10
