The impact of erosion and a brief overview of control measures is given. LC34 Vetiver grass for soil and water conservation Vetiver grass can be used as a hedge to control runoff and promote sedimentation. The uses, growing conditions, planting techniques and maintenance requirements of the grass are described. Describes the use of diversion and contour banks, constructed waterways, pasture furrows, pondage banks and strip cropping as methods of reducing erosion by controlling runoff. LC42 Erosion in school grounds High levels of pedestrian traffic create bare, compacted areas subject to soil erosion.
Students can see how erosion occurs and learn how to prevent it in their own schoolgrounds.
Grazing management LC12 Land management strategies for drought on grazing lands Drought management practices such as managing grazing pressure, water management and fodder conservation are described. The Desert Uplands Environmental and economic issues facing the grazing lands of the Desert Uplands in Central Queensland are discussed. LC45 Soil acidification Soil acidification is the gradual decrease in pH over time resulting in acidic soils with reduced productivity. Soil types and farming systems most at risk are described and management options are discussed. The South Burnett has a high proportion of the land affected by salinity in Queensland.
