FURTHER INVESTIGATIONS OF SOIL REMINERALISATION USING QUARRY FINES IN AUSTRALIA

Greenhouse trials using different types and application rates of basaltic quarry fines showed a beneficial impact on soil quality, plant health and growth. Basaltic quarry fines with higher levels of paramagnetic intensity have significantly improved plant growth when compared to basaltic quarry fines with lower levels of paramagnetic intensity. Due to the nature of basaltic quarry fines, the release of the trace elements and minerals is very slow as the quarry fines take time to break down. Experimental trials have been carried out on soil treated with quarry fines together with microbial treatments in order to "speed up" the release of minerals and trace elements. Blends of quarry fines and microbial treatments have resulted in an improvement of the plants quality due to the release of locked up minerals and trace elements. The treatment has improved the soil water holding capacity and in general, the plants health and performance. Based on the success of greenhouse experiments, field trials have been carried out with good results. A specific emphasis has been placed in particular on golf courses and on the grass playing surfaces within high profile stadiums.
