Drying Behavior of Flax Stems at Different Degrees of Dew Retting Under Simulated Rainfall: Implications for Smart Agriculture and Sensor Development

Ali Reda, Lionel Buchaillot, Steve Arscott

Dew retting of flax stems is a key agricultural process which facilitates fiber extraction from parent stems. If sensors are to be developed to monitor the degree of retting for optimal fiber extraction, then stem characteristics such as water uptake and loss need to be accurately known. Here, the...
