Gypsum Powder, Super Micronised

Ultra-fine gypsum for next-level soil health

This super micronised gypsum powder is a finely ground form of calcium sulphate dihydrate, with particles even smaller than standard micronised gypsum. That means it’s more soluble, more effective, and easier to apply by hand—no special equipment or guidelines needed.

Ideal for agriculture, horticulture, and beyond, it works as a natural soil conditioner to improve structure, aeration, drainage and nutrient uptake. The fine particle size boosts penetration for real results, especially in tired or compacted soils.

It can also help break up clay, reduce crusting, and improve water retention, making it perfect for both heavy and dry conditions. A valuable source of calcium, it also helps combat soil salinity and alkalinity, supporting healthy plant growth naturally.

Sold in 25kg sacks, ready for spreading.
