Soil Grids of Victoria: Wilting Point Predictions at 90m Resolution

A set of Digital Soil Maps providing mean, 5th, and 95th percentile prediction values for soil wilting point percentage across Victoria. The grids, produced by the Department of Energy, Environment and Climate Action, offer predictions at a 90-meter resolution for six depth intervals from 0 to 200 cm. The methodology is based on the Australian Soil and Landscape Grid and aligns with GlobalSoilMap specifications.

Use Cases

• Modeling agricultural water stress and irrigation needs based on predicted soil wilting point values.
• Informing land use policy and planning decisions based on regional soil property trends.
• Supporting ecosystem modelling and resource management with spatially exhaustive soil attribute estimates.
• Assessing soil-environment relationships and pedogenesis at a state-wide scale using the provided confidence intervals.

Strengths

• Provides predictions for six specific depth intervals (0-5cm, 5-15cm, 15-30cm, 30-60cm, 60-100cm, 100-200cm).
• Includes confidence intervals (5th and 95th percentile values) alongside mean predictions.
• Covers the entire state of Victoria with a consistent 90-meter grid resolution.
• Follows the standardized specifications of the GlobalSoilMap consortium.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The creators advise caution for local-scale assessments, recommending use for regional to state-wide trends.
