We are investigating on-farm solutions to reduce the environmental impact of intensive irrigated pastoral agriculture while maintaining productivity and profitability.
Soil guideline values (Eco-SGVs) developed to protect terrestrial biota provide a useful means for assessing potential environmental impact of contaminants.
How can irrigation be used to maintain or increase soil organic matter (SOM) and the multiple associated benefits.
Sediment loads in some New Zealand rivers are very high. Mitigating the impacts this fine sediment has in rivers requires a catchment-wide approach to reducing soil erosion.
This project studies paddocks with both irrigated and dryland areas, to research how soil water properties may change under medium- to long-term irrigation.
Developing soil and crop sensors that map spatial variability and monitor factors that influence effective irrigation, including soil water status and crop water use.
A brief history on the development of soil classification systems used in New Zealand and how they relate to those used internationally.
An assessment of the coverage and representativeness of current soil quality monitoring sites.
An integrated soil health framework that provides a comprehensive view of soil health and resilience and can be used by a wide range of end-users .
A new method to monitor soil organic carbon stocks and stock changes in New Zealand’s managed grasslands, which occupy more than half the country’s total land area.
How the SedNetNZ erosion model can be used to better understand erosion, and manage sources of sediment.
