  • Updated description of Inherent Soil Fertility from

    Self-mulching black cracking clays are considered to be representative of South Australia’s most fertile soils, while highly leached sands are the least fertile. Each of the 61 soils representing the range of soils within SA’s agricultural lands is classified relative to these extremes. Soil properties such as soil texture, exchangeable cation characteristics, leaching capacity, acidification potential, carbonate and ironstone content are used as classification criteria. Assessments are based on an interpretation of Soil Landscape Map Units which account for variable conditions found within each map unit. This dataset was developed by the State Land and Soil Mapping Program and resides within the State Land and Soil Information Framework.

    Inherent fertility is a relative indicator of the soil's capacity to retain and release nutrients for uptake by plants, and is associated with clay and organic matter content. Mapping shows the estimated average inherent fertility based on soils present in each map unit, while detailed proportion data are supplied for calculating respective areas of each inherent fertility class (spatial data statistics).
