Gypsum

If your soil feels more like sun-baked concrete than a thriving ecosystem, Meningie Gypsum is the heavy-hitting, natural solution you need. Mined from the pristine natural deposits of the Meningie region in South Australia, this isn't your standard, slow-acting, chunky agricultural gypsum.

Meningie Gypsum is highly regarded for its exceptional Grade 1 purity (typically testing over 90% calcium sulphate) and its signature ultra-fine particle size. Because it is ground so finely, it dissolves and goes to work rapidly, delivering essential nutrients and structural corrections to your soil when you need them most, rather than months down the track.

Key Features & Benefits

• Fast-Acting Ultra-Fine Grind: Unlike coarse alternatives that take ages to break down, the fine grain size maximizes surface area contact with the soil. This means significantly faster dissolution and quicker results.

• Premium Grade 1 Purity: Boasting an incredibly high concentration of Calcium and Sulphur, it ensures you are paying for active, hard-working minerals—not heavy, useless filler.

• The Ultimate Clay Breaker: Got sticky, waterlogged, or crusting clay? The calcium in Meningie Gypsum displaces excess sodium, opening up tight soil profiles to dramatically improve aeration, root penetration, and water drainage.

• Natural & Eco-Friendly: 100% naturally occurring and completely safe for everything from large-scale organic viticulture to home veggie patches.

• Excellent Water Flocculant: Due to its high solubility and fine particle size, it is incredibly effective at clearing up muddy, turbid farm dams by binding to suspended clay particles and causing them to sink to the bottom.

Best Used For

• Broadacre Agriculture & Viticulture: Ideal for broadacre spreading and vineyard management to correct sodic soil profiles, eliminate crop waterlogging, and supercharge yields.

• Home Gardens & Veggie Patches: Perfect for boosting the size, structural strength, and flavor of home-grown vegetables by providing a direct shot of easily accessible Calcium and Sulphur.

• Sporting Grounds & Turf Prep: Keeps high-traffic turf surfaces well-drained, deeply rooted, and resistant to heavy foot-traffic compaction.

• Dam Water Clarification: Can be applied directly to muddy dams to quickly drop suspended sediment, leaving behind clearer water.

Pro-Tip: Unlike lime, gypsum is pH-neutral and won’t raise your soil’s alkalinity. If you have alkaline clay soils (highly common across South Australia) that desperately need structural improvement without driving the pH any higher, Gypsum is exactly what you should reach for.
