AQUEOUS SUSPENSION PREPARATIONS AND THE USE OF SAME AS LEAF FERTILISERS

摘要

The invention relates to a novel aqueous suspension preparation comprising a water-suspended microparticulate calcite mineral with a particle diameter ≦35 μm, plant extract, and a surfactant that can shift the zeta potential of the water-suspended microparticulate calcite mineral into the negative range, and the use of this aqueous suspension preparation as a foliar fertilizer. The invention also relates to a foliar fertilizer comprising this aqueous suspension preparation.
