In May, our Healthy Estuaries WA Innovative Remediation Team hosted a field day with North Metropolitan TAFE students at our trial site at Cox Bay Lakes in Mandurah. DWER scientists Ryan, Mark and Zoe provided hands-on learning experiences, introducing students to some of the water quality assessment techniques used to evaluate the impacts of hydrotalcite clay treatment at the local lake. Working in groups, the students calibrated instruments including a … Read More
Cox Bay lake clay trials continue
Trial work exploring clay-based products to reduce phosphorus concentrations and algal growth has been continuing in Mandurah’s Cox Bay North Lake this summer. We applied a phosphorus-binding clay product called hydrotalcite clay (HT-clay) to the lake in early November 2024. A few hours after the application, the phosphate concentrations in … Read More
Clay trial reduces phosphorus to prevent algal growth
Recent trials of phosphorus-binding clay in the Peel–Harvey estuary catchment have successfully reduced the amount of phosphorus available for algal growth.
Clay trials on dryland dairy pasture improving nutrient retention
Our latest farm trials using clay as a soil amendment are starting to show positive results in improved nutrient retention.
Farm trials confirm IMG effectiveness on dairy farms
Our latest farm trials of the soil amendment Iron Man Gypsum (IMG) are continuing to build confidence in the effectiveness of IMG to improve soil nutrient retention.
New report on soil amendments to keep nutrients on farm
A new technical report details the findings of trials with the soil amendment Iron Man Gypsum (IMG) on a dairy farm in the Vasse Catchment.
New trials to provide insights for best practice soil management on sandy soils
Two new trial sites on dairy farms in the Vasse and Scott River catchments have been launched to demonstrate how top-dressing applications of Iron Man Gypsum (IMG) can keep phosphorus on farms where it is needed, instead of being washed into our estuaries where it can cause algal blooms and … Read More
Digging deep to protect our waterways
Hidden deep in the soil of a dairy farmer’s paddock could be a solution to help look after waterways, prevent harmful algal blooms and improve farm productivity. Scott River dairy farmer Brad Boley is working with scientists at the Department of Water and Environmental Regulation (DWER) and local catchment group … Read More
