  • The soil erodibility factor K used in the Revised Universal Soil Loss Equation can be calculated by two general applicable models. Data on the various soils covering northern Belgium are processed to evaluate the use of these models. Erodibility
  • factors are calculated for the top layer of soils where rill and interrill erosion occur. The K-values generated by each model are then compared throughout the range of soil types varying erodibility. For both models average K-values per unit area

  • Replicated runoff and soil loss measurements were made on nine Morrocan soils having 9 to 10 % slopes using a rainfall simulator. The objectives of the study are to relate soil erodibility to major physical, chemical and mineralogical properties
  • of some surface soils in Morocco and to develop a predictive erodibility erodibility index that uses simple laboratory-determined properties applicable to these soils.

  • This paper examines the interrelationships between aggregate stability, soil physicochemical properties and pore size charateristics which determine soil erodibility. The study is based in an area of the humid tropics where grassland fires
  • are frequent in the dry season. In order to assess the erodibility impacts of fire, differences in soil properties were determined for 4 areas at various post-fire recovery stages.

  • Erodibility and infiltration characteristics of five major soils of southwest Spain
  • In this study soils from the major soil orders of southern Spain, developed in 3 different parent materials, were subjected to simulated rainfall to : 1) determine interrill erodibility and infiltration characteristics of some important agricultural
  • soils of southern Spain, and 2) test empirical relationships of soil interrill erodibility developed in the USA on those soils. The hypotheses tested were : 1) interrill erodibility of soils from Spain and the USA is controlled by similar soil properties

  • Erodibility of a soil drainage sequence in the loess uplands of Mississippi
  • Aggregate ; Erodibility ; Loess ; Mississippi ; Rill wash ; Slope gradient ; Soil ; Soil erosion ; Soil properties ; United States of America ; Valley ; Water erosion
  • The aims of this paper were to determine how soil properties that affect erodibility vary between slope position and drainage class for a hydrosequence of soils developed in loess deposits of the lower Mississippi River Valley. Soil samples were
  • collected from the A- and B-horizons of the 5 representative pedons in the Memphis catena whose drainage class varied from well-drained to poorly-drained. Soil erodibility was assessed by the use of an aggregation index computed from water dispersible clay
  • relative to total clay contents. The results suggest that cementing agents responsible for soil aggregate stabilization are mobilized under conditions of relatively low redox potentials which increase soil erodibility.
