Soil Water Content- and Soil Matric Potential-Based Irrigation Trigger Values for Different Soil Types

July 11, 2019
Keeping a close eye on soil water content in individual fields can help optimize irrigation efficiency. This article explores how to use research-based trigger points for various soil types using soil water content-based sensors or soil matric potential-based sensors. Nebraska research has shown that having 25% more water than needed in the maize root-zone reduced grain yields as much as 15 bu/ac.
