Abstract

La présente invention vise à fournir un système de gestion agricole ou similaire qui est apte à fournir des informations de gestion concernant des cultures, lesquelles sont appropriées pour des champs lorsqu'un événement s'est produit. Le système de gestion agricole comprend un terminal de détection qui mesure des informations sur l'environnement pour un ensemble de champs et transmet les informations sur l'environnement mesurées de ces champs à un serveur ; et un serveur qui stocke, pour chacun d'une pluralité de champs, une valeur d'évaluation indiquant la valeur de production des cultures récoltées sur le champ par le passé, en association avec des informations relatives à l'environnement pendant les périodes de croissance durant lesquelles les cultures ont été cultivées, qui reçoit les informations sur l'environnement actuelles pour les champs transmises par le terminal de détection, qui prépare, sur la base des informations sur l'environnement actuelles, des informations d'adaptation à l'environnement indiquant l'environnement nécessaire pour récolter des cultures d'une valeur d'évaluation désignée, et qui transmet les informations d'adaptation à l'environnement pour chaque champ à un terminal portable détenu par un utilisateur exploitant chaque champ.
