Plant soil correlation study
Plant soil correlation study number 8, various plants. Organ Mountains in background. The vegetation is composed of 60% Larrea glutinosa, 20 percent Flourensia cernua, 8 percent Prosopsis glandulosa, and 5 percent Yucca macrocarpa. The average density is .25 and the forage acre factor is .004. Slope gradient uniformly 4 percent. Micro-relief is expressed by low wind hummocks to 6 inches high, and remnants of former levels slightly reduced by sheet wind erosion is slight and rill erosion occasional with poorly expressed channels 6 to 10 inches deep, and 1 to 2 feet wide. The soil is shallow, gravelly, very fine sandy loam. The profile has a weak indication of compaction and a well cemented and hard pebbly and stony caliche, the latter between 20 and 40 inch levels below the undistributed surface. This horizon is underlain by loess, the grass roots are physically unable to reach. However, an abundance of old rootlets indicates former penetration. Original photo number 145.
