Influence Of A Soil Microfloral Crust On Hydrologic And Chemical Properties Of Soils In Southeastern Utah, Walter L. Loope
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Cryptogamic soil crusts within the Colorado Plateau were studied to determine their effect on infiltration rates, potential sediment production, permeability, and several chemical properties of the soil. Six different crust stages were identified. Undisturbed soil cores were used to determine intrinsic permeability under three treatments and disturbed soil samples were analyzed for pH, percent organic matter, soil texture, Ca+Mg content and total conductivity.
It was found that the cryptogamic crust had little effect on soil chemical properties. Analysis of undisturbed soil core data indicates that high cryptogamic cover tends to decrease intrinsic permeability; this effect was reinforced when cores were …
