Custom Soil Resource Report Plinthite The sesquioxide-rich, humus-poor, highly weathered mixture of clay with quartz and other diluents. It commonly appears as red mottles, usually in platy, polygonal, or reticulate patterns. Plinthite changes irreversibly to an ironstone hardpan or to irregular aggregates on repeated wetting and drying, especially if it is exposed also to heat from the sun. In a moist soil, plinthite can be cut with a spade. It is a form of laterite. Plowpan A compacted layer formed in the soil directly below the plowed layer. Ponding Standing water on soils in closed depressions. Unless the soils are artificially drained, the water can be removed only by percolation or evapotranspiration. Poorly graded Refers to a coarse grained soil or soil material consisting mainly of particles of nearly the same size. Because there is little difference in size of the particles, density can be increased only slightly by compaction. Pore linings See Redoximorphic features. Potential native plant community See Climax plant community. Potential rooting depth (effective rooting depth) Depth to which roots could penetrate if the content of moisture in the soil were adequate. The soil has no properties restricting the penetration of roots to this depth. Prescribed burning Deliberately burning an area for specific management purposes, under the appropriate conditions of weather and soil moisture and at the proper time of day. Productivity, soil The capability of a soil for producing a specified plant or sequence of plants under specific management. Profile, soil A vertical section of the soil extending through all its horizons and into the parent material. Proper grazing use Grazing at an intensity that maintains enough cover to protect the soil and maintain or improve the quantity and quality of the desirable vegetation. This practice increases the vigor and reproduction capacity of the key plants and 59
