A Greener Way

Soil Conditioning

We work closely with Queensland farmers, growers and primary producers to manufacture and supply a wide range of high-quality natural minerals that support soil rehabilitation, promote optimal growing conditions and enhance animal health.

Soil Conditioning Products

Lime – (CaCO3) is a strong source of Calcium (Ca) and is used to raise soil pH (reduce soil acidity) which in turn improves the uptake of NPK fertilisers.
Dolomite – (CaMg(CO3)2) is often used to adjust soil pH in the same way as lime with the added benefit of Magnesium (Mg) to assist in balancing the soils Calcium to Magnesium ratio. A good ratio assists in moving nutrients through the plant.
Gypsum (CaSO4.2H20) is used as a quick source of calcium (Ca) but does not adjust the pH of the soil. The sulphur (S) in the gypsum supports and enhances the photosynthesis process. Gypsum is used as a clay breaker to help with water penetration and retention in areas that are irrigated. 
Calcium Silicate (Ca2SiO4 / Ca2SiO3) is a naturally occurring mineral (not mixed) which adjusts soil acidity similar to lime with the added benefit of silicon which strengthens the cell walls in plants and helps the plant resist pests and diseases. 
Magnesium Oxide (MgO) will raise soil pH and help improve the chlorophyll (green pigment) in plants which in turn improves photosynthesis and plant growth. 
Natural Rock Phosphate is a natural source of phosphorus (P) and supports strong root development over longer periods.
Custom Blends – we also provide both standard and custom blends to suit your needs, contact our friendly team to discuss your needs and the options available. 
Packaging Options Most of our products are available in various packaging and delivery options including; Delivered and spread in bulk, Delivered in bulk, 1 tonne bags, ½ tonne bags or 25kg bags.

Natural Health

Essential Minerals For Livestock

Calcium carbonate is an important component for the healthy growth and development of all livestock and domestic animals and is regularly used in feed supplements. It supports bone and skeleton development in young animals, helps with milk production in cattle, assists in the retention of nutrients and strengthens eggshells for egg laying hens.

Livestock Supplement Products

Supplying the highest quality natural calcium supplements for animal and poultry feeds, feedlot supplements and stock licks, these include:

Lime – (CaCO3) is a strong source of Calcium (Ca) and is used in stock feeds, aquaculture, and an inert filler in many other industrial applications. Powdered lime is popular in a variety of stock feed blends.
Fine Grit – is a 1mm sized calcium carbonate product that is manufactured at our Mt Garnet site using a standard crushing, milling, and sizing process. The finished product is off-white to grey in colour and is used in a variety of stockfeed blends and poultry feeds
