Abstract: The present invention relates method for the production of a thiosulfate comprising the steps of(i) providing a thiosulfate A represented by formula (X)n(S2O3)m;(ii) providing a compound B represented by formula (Y)o(Z)p;(iii) contacting the thiosulfate A of step (i) with the compound B of step (ii) in the presence of a solvent, thereby obtaining a reaction mixture comprising a compound C represented by formula (X)q(Z)r and a thiosulfate D represented by formula (Y)s(S2O3)t;wherein the ratio of the solubility of the thiosulfate D in the solvent at a predetermined temperature to the solubility of the compound C in the solvent at the same predetermined temperature is at least 5:1 or less than 1:5. The invention also relates to liquid fertilizers obtainable by the method of the invention.
