FSG Webinar 5: Identifying and addressing soil constraints and their impact on nutrient management

Dr Lukas Van Zwieten discusses common chemical, physical and biological soil constraints that can impact on crop and pasture production.

While fertilisers are often applied to constrained soils, the response can be negligible if critical issues are not addressed. Lukas presents strategies to overcome soil constraints and maximise fertiliser response.

Dr Lukas Van Zwieten
is a Senior Principal Research Scientist with the NSW DPI's Soil and Water team.

Lukas is an expert in soil chemical and biological processes and has published over 130 scientific papers, including publications ranked in the top 1% internationally in this field of research. He is also a Web of Science Highly Cited Researcher.

His research focuses on soil processes including carbon and nitrogen cycling, and how these relate to greenhouse gas emissions, contaminants in the soil environment, and unravelling microbial, rhizosphere and soil chemical processes.

FSG insights: Understanding nitrogen loss pathways

Lukas recently compiled an article specifically for the Clean Coastal Catchments’ Fertiliser Stewardship Group on the optimal use of nitrogen to improve productivity and reduce nutrient pollution in the broader environment.

'Towards a better understanding of Nitrogen loss pathways and fertiliser management' canvasses the effectiveness of enhanced efficiency nitrogen fertilisers, the benefits of slow release fertilisers, organic amendments and biological nitrogen fixation, and the development of rapid testing for potentially minieralisable nitrogen.
