Custom Soil Resource Report <br /> Forest cover <br /> All trees and other woody plants (underbrush) covering the ground in a forest. <br /> Forest type <br /> A stand of trees similar in composition and development because of given <br /> physical and biological factors by which it may be differentiated from other <br /> stands. <br /> Fragipan <br /> A loamy, brittle subsurface horizon low in porosity and content of organic matter <br /> and low or moderate in clay but high in silt or very fine sand. A fragipan appears <br /> cemented and restricts roots. When dry, it is hard or very hard and has a higher <br /> bulk density than the horizon or horizons above. When moist, it tends to rupture <br /> suddenly under pressure rather than to deform slowly. <br /> Genesis, soil <br /> The mode of origin of the soil. Refers especially to the processes or soil-forming <br /> factors responsible for the formation of the solum, or true soil, from the <br /> unconsolidated parent material. <br /> Gilgai <br /> Commonly, a succession of microbasins and microknolls in nearly level areas or <br /> of microvalleys and microridges parallel with the slope. Typically, the microrelief <br /> of clayey soils that shrink and swell considerably with changes in moisture <br /> content. <br /> Glaciofluvial deposits <br /> Material moved by glaciers and subsequently sorted and deposited by streams <br /> flowing from the melting ice. The deposits are stratified and occur in the form of <br /> outwash plains, valley trains, deltas, kames, eskers, and kame terraces. <br /> Glaciolacustrine deposits <br /> Material ranging from fine clay to sand derived from glaciers and deposited in <br /> glacial lakes mainly by glacial meltwater. Many deposits are bedded or <br /> laminated. <br /> Gleyed soil <br /> Soil that formed under poor drainage, resulting in the reduction of iron and other <br /> elements in the profile and in gray colors. <br /> Graded striperopping <br /> Growing crops in strips that grade toward a protected waterway. <br /> Grassed waterway <br /> A natural or constructed waterway, typically broad and shallow, seeded to grass <br /> as protection against erosion. Conducts surface water away from cropland. <br /> 46 <br />
