Soil and Landscape Animations
A series of animations are provided to show processes relevant to soil and landscapes with a particular focus on agricultural systems and landscapes. The 'back' button can be used to navigate back to this page.
| Carbon cycle animation Carbon is essential to life on earth, with every living organism needing carbon to sustain life whether for physical structure, or as an energy source, or both. This animation shows the carbon cycle from an agricultural prospective. |  | | |  A scene from an animation explaining the soil carbon cycle |
| Nitrogen cycle animation Approximately 78 % of the earth's atmosphere is nitrogen, however, atmospheric nitrogen is unavailable for biological use. Atmospheric nitrogen must undergo an important process called fixation to make it available for plants to use. The animation shows the nitrogen cycle from an agricultural prospective. | | | |  A scene from an animation showing the nitrogen cycle |
| Dispersion process animation This animation demonstrates the difference between exchangeable cations on clay dispersion of two dry aggregates of a sodic soil dispersing when hydrated. It is possible to interact with the dry aggregates of sodic soil in the dispersion animation. | | | |  A scene from an animation that explains the process of soil dispersion |
| Acidification animation The acidification of agricultural soils is a common problem in some areas. Agriculture can decrease the pH of soil through practices such as harvesting hay and grain, applying fertilisers, and cropping with legumes. | | | |  A scene from the soil acidification process animation |
| Coastal Acid Sulfate Soil animation Coastal acid sulfate soils occur naturally in some landscapes and if left undisturbed, can be harmless. If they are disturbed, i.e. water drains from the soil and air enters, they can react with oxygen and produce sulfuric acid. The following animation provides a simple illustration of how acid sulfate soils may be exposed to oxygen through various means of soil disturbance. | | | |  A scene from an animation that shows causes of coastal acid sulfate soil |
| Sub surface drip irrigation animation Subsurface drip irrigation (SDI) systems involve the placement of permanent drip tapes below the ground surface to supply water directly to the crop root zone. The animation shows a SDI system from a dairy agricultural prospective. | | | |  An animation showing how a subsurface drip irrigation system works |
