Highlight: At least one million acres of potentially productive The purpose of this study was to d&ermine relationships meadows in the central great plains are dominated by low value between existing vegetation and soil characteristics within a saltgrass. Soil chemical and physical factors have been measured to establish a microsite classification of vegetation-soil relations. The saltgrass meadow. Then, revegetation could be more readily microsites are "slickspot," "level," "mound," and

The planned because soil characteristics that influence seeding mound microsite is dominated by alkali sacaton and produces the success and forage production could be predicted by using highest basal area ground cover. The slickspots were dominated by vegetation as an indicator to lessen the need for extensive soil saltgrass, but average basal area was less than 10%. The level sites sampling. A knowledge of soil characteristics is also necessary produced a mixture of saltgrass, blue grama, and alkali sacaton. The when conducting seeding research on this site. Establishing swales contained a mixture of saltgrass, western wheatgrass, and improved forage species on this site has been extremely difficult threadleaf sedge. The greatest hindrance to the conversion of these and seeding failures have been frequent. meadows to high quality pasture is that they are on a solonetz soil. The A horizon was a favorable habitat for plant growth; it was neither Methods and Procedures saline nor alkaline. The B horizon was a serious problem to plant growth because it is hard when dry and impermeable when wet. The C horizon is saline, but it remains moist or wet throughout the growing
