Here I am giving a presentation at the Carberry, MB offsite on the VRI and microwave tech. Photo adapted from the Manitoba-Cooperator.
I gave a presentation in Carberry, MB a few months ago on the topic variable-rate irrigation. We have been working on a VRI system using microwave technology, similar to that on spacebourne soil moisture missions such as NASA’s SMAP. This type of system measures the passive microwave emissivity from the soil and derives a soil moisture value for the top 10 to 30cm. You can read more about the information from the Manitoba-Cooperator here.
