The project objective of increasing understanding of Canopy Temperature Sensors(CTS) in cotton production systems was achieved by using the technology on farm. The growers were extended information during the season on CTS to further understand how stress events affect cotton growth. A case study that captures the grower experiences over the past four seasons has been produced and can be used by researchers to gain an understanding of how the growers are using the technology and what benefits they are seeing at a farm level. It also shares the key learnings that the cotton growers and the service provider gained over a four-year period. This research provides a summary of the learnings and experience that growers have gained after four seasons of using CTS in the Macquarie Valley. The Macquarie growers saw potential in CTS as another tool to help schedule irrigations to maximise crop production. They used them over four seasons from 2015 to 2018. Porosity Services was contracted to supply the CTS, and each site was integrated with soil moisture probes and weather stations and provide a web-viewing platform for all Macquarie Cotton Grower Association(MCGA) members. CSIRO provided the CTS sensors in 2016 and then from 2016, 17 & 18, Porosity Services was contracted to supply the CTS, and each site was integrated with soil moisture probes and weather stations and provide a web-viewing platform for all MCGA members.
