Gypsum

Supplying locally produced Ag-Lime to the Wide Bay since 1990.

What is Gypsum?

Gypsum is a soft sulphate mineral, which is widely used as a fertiliser. It's also used in other products like plaster and chalk.

Our Gypsum is perfect for keeping the calcium level of your soil intact, without changing the pH of the soil. It has no neutralising value, meaning it's perfect for spreading where the pH levels are already where they need to be.

The Benefits of Gypsum

An excellent source of Calcium and Sulphur for plant nutrition without increasing the pH. Great for products like peanuts, pineapples, etc.

Gypsum has no neutralising capabilities, which means that it can be used on neutral pH soils.

Gypsum is also perfect for using on clay soils, to break them up.
