Title (EN) USE OF THERMOPHOSPHATE AS A SLOW-RELEASE FERTILIZER COATING
(FR) UTILISATION DE THERMOPHOSPHATE COMME ENROBAGE D'ENGRAIS EN VUE D'UNE LIBÉRATION LENTE
(PT) USO DE TERMOFOSFATO COMO REVESTIMENTO DE FERTILIZANTES PARA LIBERAÇÃO LENTA
Abstract: front page image
(EN)The invention "Use of thermophosphate as a slow-release fertilizer coating" comprises a group of chemical components, especially magnesium thermophosphate or potassium thermophosphate, which, when applied to water-soluble fertilizers, forms a 100% fertilizer protective layer that allows slow release of the encapsulated water-soluble fertilizer. The fertilizer coating composition with slow release fertilizer coating comprises in % by weight: a) 50-99% by weight fertilizer to be coated; b) 0.1-10% by weight pregelatinized starch; c) 1-50% by weight magnesium and/or potassium thermophosphate; d) 1-30% by weight sulphuric acid; e) 1-30% by weight phosphoric acid, in a concentration of 20-85%; f) 0-5% bentonite; g) 0-50% powdered calcined potassium phonolite or verdigris.
(FR)L'invention, intitulée "Utilisation de thermophosphate comme enrobage d'engrais en vue d'une libération lente", comprend un ensemble de constituants chimiques, notamment du thermophosphate magnésien ou du thermophosphate potassique qui, appliqué sur des engrais hydrosolubles, forme une pellicule protectrice 100% fertilisante permettant une libération lente de l'engrais hydrosoluble encapsulé. La composition d'enrobage d'engrais avec enrobage d'engrais à libération lente, comprend, en pourcentage en masse : a) entre 50 et 99% en masse d'engrais à enrober ; b) entre 0,1 et 10% en masse d'amidon pré-gélatinisé ; c) entre 1 et 50% en masse de thermophosphate magnésien et/ou potassique ; d) entre 1 et 30% en masse d'acide sulfurique ; e) entre 20 et 85%, de 1 à 30% en masse, d'acide phosphorique ; f) entre 0 et 5% de bentonite ; g) entre 0 et 50% de "verdete" ou de phonolite calciné en poudre.
(PT)A invenção "Uso de termofosfato como revestimento de fertilizantes para liberação lenta" compreende um conjunto de componentes químicos, especialmente termofosfato magnesiano ou termofosfato potássico, que, sendo aplicado sobre fertilizantes solúveis em água forma uma película protetora 100% fertilizante que proporciona liberação lenta do fertilizante solúvel em água encapsulado. A composição de revestimento de fertilizante com revestimento de fertilizante de liberação lenta, compreendendo percentual em massa de: a) fertilizante a ser revestido de 50 a 99% em massa; b) amido pré-gelatinizado de 0,1a10% em massa; c) termofosfato magnesiano e/ou potássico de 1 a 50% em massa; d) ácido sulfúrico de 1 a 30% em massa; e) ácido fosfórico, em concentração de 20 a 85%, de 1 a 30% em massa; f) bentonita de 0 a 5%; g) verdete ou fonolito potássico calcinado em pó de 0 a 50%.
