  9. Soil PropertiesSoil Salinity Reduces Yield Yield Decrease Electrical Conductivity (mmhos/cm)

  10. Soil PropertiesConclusions • Soil texture and depth determine : • WHC for water storage and CEC for nutrient status. • Crop productivity is linked directly to texture and depth. • Productivity can be decreased by: • increased salts • increased bulk density
