WHAT IS PURASIL?
Purasil is raw Diatomaceous Earth mined from sedimentary layers deposited millions of years ago in a fresh water lake. It is light in weight, chalk-like in appearance, very porous and comprises siliceous fossils of plant algae. It consists primarily of amorphous silica as distinct from crystalline silica or quartz. Amorphous silica is much more soluble than crystalline silica and is not a health hazard.
Silica, like calcium, strengthens cell walls resulting in robust and efficient plants. Silica improves brix levels and therefore flavour. Plants produce more flowers and pollen is more viable resulting in better fruit set. The CSIRO in Townsville has demonstrated that big increases in yield can be achieved from sugar cane by adding plant available silica to the soil.

Kleensorb is a calcined (super-heated) Diatomaceous Earth that is often added to potting mix or used as a growing medium due to its ability to hold water, create aeration and provide plant available silica. Has many other horticultural and domestic uses.
Volcanic Rock Dust (Trace Mineral Fertilizer) is great for mineralizing soils with Silica, Potassium, Phosphate, Magnesium, Iron, Nitrogen, Zinc and many more. Helps soften soils and gives fruit and vegies better taste and nutrition.
PALAGONITE (soil support) is a natural basalt rock dust soil re-mineraliser. Provides macro nutrients calcium, magnesium, phosphorous and minor potassium to the soil, as well as iron and plant available silica. Provides micronutrients and trace elements such as cobalt, zinc, copper, nickel, molybdenum, and selenium.
Zeolite's molecular matrix prevents the uncontrolled leaching of nutrients and fertilisers from your soil, keeping them available for your plants. Suitable for virtually all plants. Especially popular for growing Bonsai and Roses.
Highly Recommended! Is widely used by professional nurseries to grow and maintain their stock. Can be used on all plants (including sensitive natives) in all seasons, gives excellent fast results and does not "burn plants" or produce offensive odors and is a long lasting PH balancing fertilizer. Unique, economical and easy to use.
