Irrigation et fertigation adaptative au stress

Selon certains modes de réalisation, l'invention concerne un système d'irrigation souterraine conçu pour fonctionner dans un mode sensible aux plantes, et conçu en outre pour effectuer certaines adaptations en réponse à un stress de plante. Des adaptations au stress peuvent consister, par exemple, à augmenter sélectivement la pression source d'un fluide d'irrigation, à chauffer ou à refroidir le fluide d'irrigation, et/ou à injecter des amendements fertilisants et/ou non fertilisants dans le fluide d'irrigation. A method for irrigating, comprising the steps of:a) performing sub-surface irrigation via microporous tubing treated with a hydrophilic polymer in a root-responsive mode, the root-responsive mode whereby a relatively low supply pressure and a closed-end fluid path;b) determining a plant stress condition;c) selecting a system-delivered treatment based on the plant stress condition,the system-delivered treatment including a relatively high supply pressure and a recirculating fluid path;d) performing the system-delivered treatment;e) terminating the system-delivered treatment;f) determining whether the system-delivered treatment included fluid amendment; andg) if the system-delivered treatment included the fluid amendment, clearing the system; and if the system-delivered treatment did not include the fluid amendment, performing the sub-surface irrigation via the microporous tubing treated with a hydrophilic polymer in the root-responsive mode.
