How do you interpret the soil tensiometer readings?
When the soil tensiometer vacuum gauge reading is within the ranges below interpret as indicated:
- Saturated soil
- 1-10: Surplus water (free water range)
- 11-20: Field capacity range (clay, slit, sand)
- 21-30: Sand irrigation start range
- 31-50: slit (loam) irrigation start range
- 51-60: clay irrigation start range
- 61-78: Plant stress range (Limit of readily available water)
