Water Harvesting

This is a great image showing water harvesting in a tillage system, the day after an opening rain. This particular soil, located in the Mid North of South Austrlia, is suited well to a tillage machine. Tillage allows the soil to be broken apart, and aerated. This soil has a dispesive layer at a depth of 4-6 inches; using a tine to fracture this allows for better infiltration of water, and more root growth. Furrows are also created, which means that water can be ‘harvested’, running the water into the root zone of the plant, where it will be used most efficiently. It is important to choose if tillage is right for your broad acre system, and to assess the benefits and limitations of each seeding method, to predict which would be best suited to you.
