The invention relates to suspensions containing: i) one or more plant nutrients; ii) one or more specific homo- or copolymers; iii) one or more solvents; and iv) optionally one or more additional auxiliary materials. The homo- or copolymers contain recurring structure units of formula (I), wherein R1 represents hydrogen or methyl, A represents C2-C4-alkyls, B represents a C2-C4-Alkyl that is different from A, m is a number from 0 to 500, n is a number from 0 to 500, and the sum of m + n is equal to 1 to 1000, and Pa represents hydrogen, an acid group or the salt thereof, or represents the monovalent organic group containing one or two acid groups or the salts thereof. The suspensions according to the invention are advantageously suitable for supplying plants with one or more plant nutrients.
