Abstract
Abstract. Many nurseries are considering soil moisture sensor networks to improve water application efficiency. Due to the necessarily wide distribution of sensors at a nursery, a wireless network is easier to install, more flexible, and can be scaled up as needed without re-design as compared to a traditional wired sensor network. When choosing a wireless network, a matter of critical importance is the network reliability. This study examined the reliability and usability of a commercially available, mesh-style wireless network used at a container nursery. We found that the network failed to record approximately 20% of scheduled sensor readings and that usability was limited due to a fixed 15-min reading interval. However, the system function was sufficient for calculating irrigation set-time and monitoring net irrigation and evapotranspiration when overhead irrigating containerized nursery crops. Results led to discussion of optimum characteristics of a wireless monitoring network system and to what extent this system embodied each of them.
