PIRSA Growing Carbon Farming Demonstration Pilot

This project aims to build on the information presented and the grower activities at VRT workshops where all participants selected a paddock on their own property and started to use public satellite NDVI data to establish their own soil zones to begin the VRT journey.

Enhancing farmer knowledge of soil function

This project aims to provide “the why” behind the decisions SA farmers need to make in relation to adopting practices to address the range of SA specific soils characteristics, soil biology, subsoil constraints, soil nutrition dynamics, etc. It will do this by posing a series of specific questions about soils from an on-farm management perspective.

Building knowledge and capacity in growers/ advisers to diagnose sandy soil constraints to ensure successful amelioration of sands

Improve the capacity of farmers in the low rainfall Mallee and Northern Yorke region to correctly diagnose underlying constraints that limit the productivity of sandy soils, to select the most appropriate strategy or combination of strategies to ameliorate the soil constraints present, and to map soil constraint data at a paddock scale to better target costly amelioration activities.

Building drought resilience on Mallee Farms

This project has been funded to help Mallee farmers tackle wind erosion with practical ways of improving and maintaining groundcover on erosion-prone soils.

There are two main themes in the project:

1. Promoting cropping practices that improve crop performance and leave more ground cover

2. Promoting forage shrubs and livestock containment designs to broaden the livestock feedbase and protect groundcover on vulnerable soils.

Optimising Soil Amelioration Costs in Typical Mallee Soils

Trials at Walpeup (VIC Mallee) and Parrakie (SA Mallee) are putting a range of ripping tines, accessories and delving tines to the test on compacted deep sands. By quantifying draft force and soil loosening, researchers can calculate the efficiency of ripping tines and other soil amelioration tools. Roughly, the more soil loosened for every unit of draft force, the more efficient the equipment is.
