Title: Soil structure: concepts, description and interpretation
Author: McKeague, J. A.; Wang, C.
Abstract: A review of systems for describing soil structure leads to the conclusion that soil porosity should be included as a basic aspect of structure description, perhaps the most important aspect for interpretations based on structure. Improvements are proposed in procedures for describing soil macrostructure in the field and refinements are suggested in definitions of terms related to soil structure. Such changes are shown to be necessary to foster uniformity of soil descriptions in soil survey. Preliminary data are presented that indicate a good possibility of making useful estimates of saturated hydraulic conductivity from observations of soil structure, including porosity. Preliminary testing of the British Soil Survey system of estimating the air porosity and available water capacity of soils from field observations are sufficiently promising to warrant further work to refine the guidelines involved.
