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 stripcropping <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 />Custom Soil Resource Report <br />40 Index #10
