Aggregate Stability: Its Relation to Organic Matter Constituents and Other Soil Properties  (site info) A paper by T.B.S. Christopher, 1996. http://www.agri.upm.edu.my/jst/resources/as/om_toc... 3. Tutorials in Soil Physics  (site info) These tutorials range in difficulty from college sophomore to the senior/graduate/postdoctoral level. They begin with the basics and extend to a new exact solution to Richards' equation for unsaturated horizontal and vertical flow. http://www.aquarien.com/sptutor/index.htm 4. Determination of the plastic limit and plasticity index for soil  (site info) The plastic limit is that moisture content of a soil at which it becomes too dry to be plastic, used together with the liquid limit to determine the plasticity index which when plotted against the liquid limit on the plasticity chart enables the classification of cohesive soils. http://www.civl.port.ac.uk/projects/geotech/geo5.h... 5. Guidelines for soil sampling  (site info) Detailed explanation of how to do soil sampling in order to achieve reliable results. http://ianrpubs.unl.edu/Soil/g1000.htm 1-5 of 8. Next »
