Soil amendments which include starch-based superabsorbent polymer (SAP) particles are combined with a liquid fertilizer solution to form a flowable suspension. Methods for manufacturing the SAP liquid fertilizer suspension are disclosed. The starch-based SAP product may include a monomer graft polymerized onto a starch in the presence of an initiator to form a starch graft copolymer. Various mesh sizes of granular SAP particles may be mixed with a liquid fertilizer solution that optionally includes a micronutrient multivalent cation solution.
L'invention concerne des amendements de sol qui comprennent des particules de polymère superabsorbant(SAP) à base d'amidon, qui sont combinés avec une solution liquide d'engrais pour former une suspension fluide. Des procédés pour préparer la suspension liquide d'engrais SAP sont décrits. Le produit SAP à base d'amidon peut comprendre une greffe de monomère polymérisée sur un amidon en présence d'un initiateur pour former un copolymère greffé d'amidon. Diverses tailles de maille de particules SAP granulaires peuvent être mélangées à une solution liquide d'engrais comprenant facultativement une solution cationique polyvalente de micronutriments.
