| Centibar Reading | Soil Condition | |

| 0-10 |
Saturated Soil. Occurs for a day or two after rain or irrigation. |
|
| 11-30 |
Soil is adequately wet (except coarse sands which are drying out at this range). |
|
| 31-60 |
Usual range to water (except heavy clay soils). Water at the upper end of this range in cool humid climates and with higher water-holding capacity. |
|
| 61-100 |
Usual range to irrigate heavy clay soils. |
|
| 101-200 |
Soil is becoming dangerously dry for maximum production. |

ET describes the sum of evaporation and plant transpiration from the surface to the atmosphere. Evaporation is the movement of water to the air from the soil, canopy interception, and water bodies. Transpiration is the movement of water within a plant and the subsequent loss of water as vapour through stomata in its leaves.

The 7-Day Index (20.3mm) is a very useful and accurate guide used to determine how much water is needed to maintain your plants. It is derived by taking the last 7 days of rainfall (25.8 mm) minus the last 7-Day ET (5.5 mm), measured by Gosport Weather. The index represents the amount of water needed to replace that lost by ET over the last week. (A positive 7-Day Index means excess water is present).
Precip amounts of 0.2mm (0.01in) are indicative of dew, frost, mist, fog, or a very brief shower.
Information
Determine your soil composition: Soil Survey
Soil / Grass conditions are monitored by a Davis Soil Moisture/Temperature Station and Extra Temperature Station. The combined station is comprised of an anemometer, barometer, temperature and humidity sensors, rain gauge, solar radiation sensor, UV sensor, 1 thermo sensor (measuring grass temp), 1 leaf wetness sensor, 4 soil moisture sensors, and 4 thermo sensors positioned in the soil (measuring ground temps and providing soil moisture condition). Evapotranspiration and Irrigation values are calculated using Weather Display.
