Cela nous permet d&rsquo;ajuster avec pr\u00e9cision les cycles d&rsquo;irrigation.<\/p>\n<p>En 2023, un projet de recherche men\u00e9 par le D\u00e9partement des Sciences et Technologies Agricoles, Alimentaires, Environnementales et Foresti\u00e8res (DAGRI) de l&rsquo;Universit\u00e9 de Florence a \u00e9t\u00e9 r\u00e9alis\u00e9 dans notre entreprise. Ce projet visait \u00e0 \u00e9tudier les effets de l&rsquo;**irrigation d\u00e9ficitaire** et l&rsquo;application de capteurs foliaires pour \u00e9valuer l&rsquo;\u00e9tat hydrique des plantes, dans le but de r\u00e9duire les apports en eau.<\/p>\n<p>Trois exp\u00e9rimentations distinctes ont \u00e9t\u00e9 men\u00e9es sur **Morus alba** et **Cinnamomum camphora**. Les r\u00e9sultats ont montr\u00e9 que les plantes soumises \u00e0 un stress hydrique mod\u00e9r\u00e9 n&rsquo;ont connu qu&rsquo;une r\u00e9duction minimale de croissance (2 %) par rapport aux plantes b\u00e9n\u00e9ficiant d&rsquo;une irrigation normale. Ces r\u00e9sultats laissent entrevoir un potentiel significatif d&rsquo;\u00e9conomie d&rsquo;eau.<\/p>\n<p>Les plantes ont \u00e9t\u00e9 soumises \u00e0 deux niveaux de stress hydrique : mod\u00e9r\u00e9 (r\u00e9duction de 30 % de l&rsquo;eau) et \u00e9lev\u00e9 (r\u00e9duction de 50 %). Aucune des deux conditions n&rsquo;a entra\u00een\u00e9 de variations significatives du **contenu relatif en eau** (RWC). M\u00eame avec une r\u00e9duction de l&rsquo;apport en eau, les plantes ont pu maintenir une hydratation suffisante pendant une p\u00e9riode prolong\u00e9e, y compris durant l&rsquo;\u00e9t\u00e9.<\/p>\n<p>\u00c0 partir de 2024, sur le site \u00ab Ferruccia 300 \u00bb, nous avons lanc\u00e9 un suivi suppl\u00e9mentaire des sols gr\u00e2ce \u00e0 des capteurs. Combin\u00e9s aux donn\u00e9es des stations pluviom\u00e9triques, ces capteurs fourniront des pr\u00e9visions sur le moment et la quantit\u00e9 d&rsquo;eau n\u00e9cessaires pour l&rsquo;irrigation, en fonction d&rsquo;algorithmes tenant compte du type de sol et de la vari\u00e9t\u00e9 de culture.
