Rock Dust 20kg

A natural soil additive that supplies many minerals, including magnesium, silicon, phosphorous, sulphur, potassium, calcium, manganese, iron, cobalt, copper and zinc to the soil.

It is also paramagnetic, which means that the particles tend to align with the earth's magnetic field. This has many benefits for plants:

• better water retention in the soil
• increased earthworm and microbial action
• better nutrient utilisation in the plant
• improved seed germination
• resistance to predators
• resistance to environmental stresses
