March 24, 2022: CANCID Webinar Series: Integrated Agricultural Water Management: Measuring and Modelling with Silvio Gumiere
Agriculture uses about 80% of water resources. It is, therefore, essential to use precision management practices and develop sustainable technologies and approaches to continually improve water management practices. Increasing agricultural biomass needs, in response to population growth, require the development of new agricultural practices as well as new predictive technologies of soil moisture status. Precision agriculture relies on real-time use of sensors that provide information on weather, geographical positioning, yields, water status soil fertility, and plant water stress which is then integrated into predictive numerical models. The dynamics of water in a heterogeneous soil profile cannot be expressed as an average of the hydraulic properties of the soils. In the unsaturated soil zone, the dynamics of water is governed by a strongly nonlinear relationship between matric potential and hydraulic conductivity. The objective of this presentation is to provide insights for modelling and data acquisition methods towards integrated precision water management practices in agriculture.
