Spreading / applying dust in agriculture
Rockdust can be applied to soil either via hand application, via broadcast spreader or fertigation. Where possible the rockdust can be worked into the ground either physically or by using water to wash in.

Phosphate fixation
Often phosphorus is locked in soils due to many years of application of traditional fertilisers. The use of micronutrient rich fertiliser enables plants to access locked phosphorus.

Paramagnetism
The elements high in available 2+ valence electrons, calcium, iron and magnesium in particular contribute to paramagnetism in soil which aid in cation exchange capacity.

Ph
The calcium and magnesium in high quality has the ability to neutralise ph in soils, in effect acting as a liming agent
