DescriptionPreliminary findings indicate that average soil water levels during wet seasons can be measured by inserting clean iron rods (mild steel) in the soil and measuring the depth of rust on the rods after 8 to 16 weeks. Iron rods rust rapidly in aerated soil above the water table but remain free of rust below the soil water table where air is excluded. This technique appears to work well on imperfectly and poorly drained soils.
