Managing subsoil acidity – preliminary results from the long-term field experiment locations
Aims

The objectives were to:
1. manage subsoil acidity through innovative amelioration methods that will increase productivity, profitability and sustainability
2. study soil processes, such as the changes of soil chemical, physical and biological properties under vigorous soil amelioration techniques, over the longer term.

Key messages

• Significant crop biomass responses were observed on wheat, barley and canola crops at anthesis.
• The large crop biomass responses under organic amendment treatments were largely due to extra nutrients from lucerne pellets.
• The dramatic crop biomass responses observed at anthesis on canola and barley crops did not translate into grain yield under treatments with lucerne pellets applied, due to severe lodging.
• Soil chemical, physical and biological properties will be monitored to understand the soil-plant interactions, the factors driving the differences in crop response to the various treatments and the residual value of the amendments.

Cootamundra NSW 2016 Barley

There were six treatments within each crop, arranged in a split-plot design with three replicates.
