摘要

A leaf feeding composition comprises a concentrated whey fermentate containing from 2 to 4% by weight of protein hydrolysate, macroelements and micro elements. The composition may be prepared by a method wherein a dispersion medium of concentrated whey fermentate containing protein hydrolysate is raised to elevated temperature, compounds for providing the macroelements are added to the medium, followed by a micro element concentrate and a starch suspension, and the liquid medium produced is fed to a cooling installation and cooled to ambient temperature. The leaf feeding composition of the invention is suitable for treatment of plants grown in agriculture.
