| 摘要 |
The invention relates to an aqueous suspension preparation comprising a microparticle-shaped calcite mineral suspended in water with a particle diameter of < 35 μm, a plant extract, particularly an algae extract, and a surfactant, particularly an anionic surfactant from the group of lignosulphonate, potassium oleate and diisooctyl sodium sulphosuccinate or saponins, with which the zeta potential of said microparticle-shaped calcite mineral suspended in water can be shifted into the negative range. The invention also relates to the use of this aqueous suspension preparation as a leaf fertiliser, and to a leaf fertiliser comprising this aqueous suspension preparation. |
