Understanding how physical and chemical soil properties vary at depth in different soil types can inform management decisions.
A panel of experienced consultants give their insights and suggest management on a range of example profiles from across the southwest agricultural region of WA, along with expert technical advice from Department of Primary Industries and Regional Development scientists.
Current status of micronutrients
Case study
The premise behind this trial is that for sustained improvement of soil physical properties, such as increased infiltration rate, deep ripping and gypsum should be applied together; gypsum should provide stabilisation of soil aggregates and assist in decreasing dispersion at the soil surface.
Comparing strategic deep tillage treatments for managing soil water repellence, subsoil compaction and subsoil acidity.
Quantifying the extent and timing of nitrous oxide emissions.
Variable rate application of fertiliser
Case study
Investigating how to improve the efficiency of nitrogen fertiliser using variable rate application
Developing a replacement strategy.
Investigating how crop sequences impact soil nutrient balance over a three-year period.
