Abstract

La présente invention a pour objet un engrais liquide pour culture d'un sol qui implique l'utilisation d'un nitrate d'urée qui n'a essentiellement jamais été utilisé en tant qu'engrais jusqu'à présent et qui présente des effets fertilisants très notablement amplifiés. La présente invention concerne spécifiquement un engrais liquide pour culture d'un sol qui comprend du nitrate d'urée, la teneur en nitrate d'urée étant comprise entre 0,006 et 1,2 % en poids. L'application de cet engrais liquide pour culture d'un sol à la surface d'un sol et/ou dans la terre tout en évitant le contact direct avec les feuilles des cultures en germination permet de réaliser la culture de plantes sans engendrer de phytotoxicité.
