Measured and recorded by the Davis Wireless Leaf & Soil Moisture/Temperature Station.
It accurately measures soil temperature and moisture to inform us when the grass requires watering in the summer heat.

0-10 Saturated Soil. Occurs for a day or 2 after irrigation
10-20 Soil is adequately wet
30-60 Usual range to irrigate regular soils
60-100 Usual range to irrigate heavy clay soils
100-200 Soil is becoming dangerously dry for maximum production. Proceed with caution.
Is a measurement of the amount of water vapor returned to the air in a given area.
It combines the amount of water vapor
returned through evaporation (from wet vegetation surfaces and the stoma
of leaves) with the amount of water vapor returned through transpiration
(exhaling of moisture through plant skin) to arrive at a total.
Effectively, ET is the opposite of rainfall, and it is expressed in the same units of measure (inches, millimeters).
The Vantage Pro uses air temperature, relative humidity, average wind speed, and solar radiation data to estimate ET, which is calculated once an hour on the hour.
ET requires the optional solar radiation sensor.
