The EQ3 Equitensiometer: a new advanced soil water potential sensor from Delta-T Devices
The new EQ3 Equitensiometer from Delta-T Devices uses class leading ThetaProbe technology to avoid the many problems of water-filled tensiometers. It is maintenance free and measures water potential (matric potential) in the range 0 to -1000 kPa. It provides an accurate loggable output and is particularly well suited for use in dry soils. The EQ3 is an improved replacement for the field proven ...

Method developed to measure solute movement in soils
Scientists from Aarhus University and Aalborg University in Denmark have developed a new method for measuring the movement of solutes in intact soil. Improving on the existing method, the new procedure can be used on intact, undisturbed soil and provides more confident estimates. Movement, or diffusion, of solutes in soils is involved in many processes of agronomical, environmental and technical ...

Students get a feel for soil-water relationships
Using little more than PVC rings, a trashcan, and a scale, students can literally get a feel for soil water retention and field capacity, concepts that are important and useful in fields from farming to engineering. The demonstration, developed by Adam Howard, Drs. Josh Heitman and Dan Bowman of North Carolina State University, was designed to illustrate concepts that can be difficult for ...

New irrigation strategies for pecans in humid climates
Georgia is the largest pecan producing state in the U.S. Although this humid region receives an average of 127 cm or more rainfall annually, periods of moisture stress can occur during the pecan growing season, particularly during August and September when pecans are in the kernel-filling stage and water demand is at its peak. Pecan producers throughout the region depend on irrigation strategies ...
