Phosphorus
Adding phosphorus to soil can help grow plants – but too much in our water contributes to algal blooms. These resources can improve your understanding of how phosphorus moves from land to water, and help you find effective ways to minimise phosphorus loss.

Reducing phosphorus losses from agricultural land to surface water
Enrichment of surface waters with phosphorus (P) leads to algal growth and eutrophication. About 27% of agricultural land exceeds optimal soil P levels, posing a risk of P loss to surface waters. Agricultural…
