Plant soil correlation study

Plant soil correlation study number 10 vegetation, Organ mountains in background. The vegetation is composed of 50 percent Larrea glutinosa, 40 percent Kramaria parvifolia, 5 percent Ephedra trifurea, and 5 percent Yucca sp. The average density is .25 and the forage acre factor is .03. Erosions on the area is both slight sheet and wind erosion with occasional shallow gullies. The slope gradient is uniformly 4 percent. Micro-relief is expressed by shallow sheet removal and low accumulations around plant. The soil is a shallow gray sandy semi-desert type with an extremely hard cemented caliche which has a dense semi-crystalline pavement separating it from the upper earthly layers of the profile; depth to the caliche layer is 15 inches.
