| Explanation | |
|---|---|
Dangerous Dry ( 101 - 240 cb ) | Soil is becoming dangerously dry for maximum production. |
Irrigation needed ( 61 - 101 cb ) | Usual range to irrigate heavy clay soils |
Irrigation desired ( 26 - 61 cb ) | Usual range to irrigate or water (except heavy clay soils) Irrigate at the upper end of this range in cool humid climates and with higher water-holding capacity soils. |
Adequate ( 11 - 26 cb ) | Soil is adequately wet (except coarse sands which are drying out at this range) |
Saturated ( 0 - 11 cb ) | Saturated Soil. Occurs for a day or two after irrigation. |
