Nutrient absorption of neutralised acid effluent and blends

Summary

The project and report addressed issues that needed to be resolved in order for neutralised acid effluent to be used, including:

• which mixtures of materials will provide the greatest sorption capacity for P and N;
• whether certain environmental perturbations would induce catastrophic release of sorbed nutrients; and
• nutrient availability in materials to determine their value as slow-release fertilizers.
