A number of newer and cost-effective technologies/tools have been developed to measure soil water status. Deciding which technique to use depends on the purpose of the measurements, soil and crop conditions, desired accuracy, cost and other factors. This publication defines soil matric potential and describes principles and operational characteristics of one of the electrical resistance type soil moisture sensors for irrigation management. Examples show how soil matric potential can be used for irrigation management.
