| Abstract/Contents: | "Soil water tension is a widely used parameter to manage irrigation. The collection of simultaneous information on soil water tension from many locations in a field is now made possible through wireless tensiometers. Such automatic spatial data collection results in a better assessment of the field-average tension. Additional gains in water management efficiency can be obtained if some spatial patterns can be identified which represent zones large enough to be irrigated independently. When such conditions exist, excess water is often applied if subzones of high variability are not independently managed. In this case, important excess water and energy may be used. Hence, important water savings can be obtained by recognizing spatial variability patterns in soil water tension and managing such patterns as sub-units instead of as a whole field. This paper summarizes observations obtained from different studies investigating the presence of independent zones and their effect on irrigation needs." |
