What is Gypsum and why do we use it?
Verterra recently completed a gully remediation project for Reef water protection near Collinsville in North Queensland.
A key component of the project was the incorporation of gypsum into the sub-soil profile to counteract the dispersive nature of the hard settling clay soils.
Gypsum or calcium sulphate, is a naturally occurring marine evaporite. Verterra sources gypsum from outback Queensland. It is an indispensible part of the soil amelioration toolkit for dealing with sodic soils.
Gypsum works by displacing excess sodium. This allows clay particles to aggregate, improving soil structure and water retention. It also allows air, water, nutrients, and plant roots to move through the soil profile, creating healthier, more stable soils and better conditions for vegetation growth.
Verterra specialises in soil management and landscape repair, particularly in highly dispersive soil stabilisation.
