Abstract

Engrais comprenant une source de phosphore à libération intermédiaire. La source intermédiaire de phosphore peut être la schertelite. Dans un mode de réalisation, la source intermédiaire de phosphore peut être sensiblement la totalité de la teneur en phosphore dans l'engrais. Dans d'autres modes de réalisation, l'engrais comprend en outre l'une ou les deux d'une source de phosphore à libération lente et d'une source de phosphore à libération rapide. L'engrais peut se présenter sous la forme d'un granule homogène. Un certain nombre de procédés peuvent être utilisés pour fabriquer de tels engrais.
