This project aimed to provide support to landholders in the northeastern area of the EP to address bare areas with repeated soil erosion events. This was done by providing funding to trial a range of practices to increase soil cover and providing technical support to deliver and evaluate these practices.
• Soil amelioration through ripping with inclusion plates or clay delving has supported the development of plant cover in areas with a history of wind erosion.
• Mixed species pasture systems can present an opportunity to increase soil cover and feed levels.
• Summer cover crops can deliver higher levels of soil cover over summer, providing increased soil protection and can support soil amelioration practices, such as ripping with inclusion plates.
• Compared to stubble treatments, summer cover crops can lower soil water levels when growing, but soil water levels measured post-germination showed mixed results. Even where soil water is lower, there may not be a negative impact on biomass or yield in the subsequent crop as shown in 2021.
