Lime-amended BioClay (LaBC)

West Road site: Comparison between nil application LaBC 300kg/ha Super Phosphate and 50kg/ha Urea on the left; and 200 tonnes/ha of LaBC on the right

The Water Corporation has spent more than three years developing Lime-amended BioClay or LaBC, a blend of sterile lime-amended biosolids with virgin gravely clay from the Darling Range. 

Extensive laboratory testing, glasshouse and field trials have demonstrated that LaBC is a safe, valuable soil improver and low-leaching fertiliser suitable for the acid sandy soils of the Swan Coastal Plain.

When applied as directed, LaBC is safe for humans, animals and the environment, and significantly improves the survival and growth of annual and perennial grasses, native plants and farm trees.

Landholders in the Ellen Brook catchment are invited to use LaBC to improve the sustainability of their farms in partnership with the Water Corporation.
