5: Soil Physical Properties & Soil-Water Relations

  • Page ID
  • Learning Objectives

    • Define soil texture and understand its influence on water infiltration, percolation and soil water holding capacity
    • Understand the relationship between soil texture and structure
    • Describe the relationships between bulk density and porosity and particle density and porosity
    • Learn to calculate bulk density, particle density, and porosity of a soil sample
    • Measure soil moisture to examine the influence of density and texture on water holding capacity
    • Identify conditions under which soil is most susceptible to erosion by water and wind

    GOAL: To understand soil texture and structure and their influence on soilwater relations
