Management Considerations

  • Texture contrast soil.
  • Very deep sandy hydrophobic surface soil, susceptible to wind ,sheet and rill erosion.
  • Slightly acidic upper surface to alkaline subsurface and subsoil.
  • Weakly developed sodic clayey subsoil.
  • Duneslope, well drained site drainage.
