Watermark® sensors' measurement can be automated allowing
them to be easily integrated into soil moisture data acquisition systems
and wireless data transmission networks. These networks are composed
of many autonomous, cooperating, battery-powered, smallsized
motes. They can be connected through wireless links and a communication
gateway with a capacity to forward data from the motes
to a base station with high processing and storing capacities. This
makes it possible to monitor the soil water potential with the purpose
of providing accurate and up-to-date knowledge of the field. To our current
knowledge, there are very few studies comparing different tillage
techniques that provide daily data of soil water potential at different
depths. Such studies are generally helpful in the understanding of soil
water dynamics throughout the growing season.
