Land condition and sustainable management
There are approximately 10.4 million hectares of cleared land used for agriculture in South Australia. Most has been significantly changed by land management practices such as grazing, cropping and the application of fertilisers, herbicides and pesticides.
There are strong links between production and sustainable land management. Best practice conservation agriculture techniques (which minimise soil disturbance and provide soil cover) help to optimise both production and land management outcomes, through enhanced soil structure, moisture retention and erosion protection.
The trends in land condition are an important indicator used to assess the impact of agricultural practices on the soil resource. This also includes the impact of improved land management technologies and practices.
Key trends include:
