High Water Demand

Posted: 22 Jun 2022 05:34 AM

The featured map presents ISU Soil Moisture Network computed potential evapotranspiration over the past seven days. The value is expressed in inches of water and represents an estimate of the maximum demand of water from vegetation assuming that the vegetation has water to spare. Some refer to this as a reference value as in this case, the reference crop is Alfalfa. Warm and windy weather along with plenty of sunshine have really dried things out over the past number of days. Signs of drought stress will certainly show up soon over much of the state unless more widespread rains are come soon given this elevated demand for water.
