    • 9.
      • Key Factors That Limit Plant Growth
        • Slope Stability
        • Protection From Erosion
        • Available Water/Infiltration
        • Nutrient Availability
        • Biological Activity
      Key Problem
    • 10. Key Treatment
      • Compost
    • 11. Compost and Soil Structure
      • Soil Soaked in Bleach
        • No Organics
        • Collapsed Structure
        • Rainfall = Erosion
        • Limited Infiltration
        • Little Retained Moisture
      • Class I Ag Topsoil
        • Plenty of Organics
        • Strong Structure
        • Limited Erosion
        • Significant Infiltration
        • Moisture Retention
