Abstract

L'invention propose un indicateur d'humidité qui convient pour indiquer en quel endroit (humide ou sec) on se trouve dans le cycle de la terre entourant les plantes cultivées. L'indicateur d'humidité de la terre comprend une chambre supérieure et une chambre inférieure, avec un passage qui les relie; en travers de ce passage, il y a une matière a sorbante imprégnée d'une composition d'indicateur sensible à l'humidité. La chambre inférieure comporte une ouverture inférieure qui, après insertion du dispositif dans la terre aboutit à ce que l'humidité relative de la chambre inférieure soit liée à l'humidité de la terre. La chambre supérieure est partiellement transparente et peut éventuellement communiquer par des évents avec l'atmosphère extérieure. L'appareil permet, sans agiter la terre, d'en connaître le degré d'humidité et, donc, le besoin en eau d'une plante cultivée (par exemple en appartement).
