| Abstract/Contents: | "Using persistent thermal and visual image data to measure the turf canopy it is possible to enable the turf to tell you about the stress it is experiencing and its water status. When scouting for stress one is looking for deviations in the canopy where the quality is not up to desired standard. Homogeneity of the turfs canopy is key. When assessing the need for irrigation the turfs irrigator may be using one of three operationally feasible methods of assessing the need for applying water; using an evapotranspiration equation, using a network of soil moisture sensors, or by seat-of-the-pants. Evapotranspiration calculated from observations from a weather station and applied to the turf by a turf coefficient. It is an estimation of the water used by the turf so one can know how much to irrigate. Soil moisture sensors measure the water in the soil so one can know, based on the fidelity of the network, where and how much to irrigate. Seat-of-the-pants is the art of looking at and touching the turf, then applying ones intuition and experience to know when and where to irrigate." |
