Claims11
A method of fertilizing a plant, the method comprising:
- making an aqueous suspension comprising a mineral having a silica content equal to or greater than about 40 wt % from a powder or a concentrated slurry, and
- applying the aqueous suspension to a seed, plant or growing substrate,
- wherein:
- the aqueous suspension comprises equal to or less than about 10% (w/v) of the mineral;
- and
- the mineral is wollastonite having:
- a d50 (sedigraph) ranging from about 4 μm to about 10 μm;
- a d90 (sedigraph) ranging from about 5 μm to about 25 μm;
- and
- a d10 (sedigraph) ranging from about 0.1 μm to about 3 μm.
