Maidenwell Diatomite is an opaline siliceous sedimentary rock consisting of microscopic fossilised skeletal remains of diatoms, a unicellular aquatic plant. Maidenwell's Diatomite deposit is ideally suited to use in the following industry applications.

• Horticulture - high silica additive for potting mix.

• Hydroponics - water saving growing medium.

• Agriculture - foliar spraying.

• Turf management - absorptive, water retention, aeration and enhanced root development.

• Building - mould and fungal inhibitor.

• Pest control - grain storage, industrial and domestic pest management.

• Shipping containers and storage - desiccant and mould inhibitor.

As a growing medium there has been a movement toward specific crops, many advantages of this product have been noted in promoting the growth of plants which is largely due to plant available silica. Maidenwell Diatomite is a rich source of plant available silica which is widely documented to stimulate Self Acquired Resistance (SAR) in plants thereby increasing their resistance to disease.

It should be noted particularly for the Rose, Gerbera, Orchid and Hydroponic applications that all samples and products offered from the Maidenwell mine site are derived only from fresh water deposits of diatomite.

Maidenwell Diatomite Australia Pty. Ltd. achieves a high standard of quality control through the employment of regular, systematic testing by our resident Geologist and a consultant Physicist. It is the ultimate objective of the company to produce the best quality product available for these Industries.

Samples of Maidenwell Diatomite (all sizes) are available upon request.
