Soil Grids of Victoria: Available Water Holding Capacity at 90m Resolution

A set of Digital Soil Maps provides mean, 5th, and 95th percentile prediction values for available water holding capacity across Victoria. The raster grids offer predictions and confidence intervals at a 90-meter resolution for six depth intervals from 0 to 200 cm. The dataset was produced by the Department of Energy, Environment and Climate Action and last updated in April 2026.

Use Cases

• Modeling agricultural water stress and irrigation needs based on predicted soil water holding capacity.
• Assessing regional trends in soil properties for land use policy and planning based on the spatially continuous estimates.
• Supporting ecosystem and hydrological modeling based on soil attribute predictions across six depth layers.
• Informing resource management decisions based on the confidence interval values provided with the predictions.

Strengths

• Provides predictions for six specific depth intervals: 0-5 cm, 5-15 cm, 15-30 cm, 30-60 cm, 60-100 cm, and 100-200 cm.
• Includes confidence intervals (5th and 95th percentile values) alongside mean predictions.
• Follows the consistent technical specifications created by the GlobalSoilMap project.
• Offers a high spatial resolution of 90 meters for exhaustive coverage across Victoria.

Limitations

• The description metadata is limited; actual data quality and column semantics require manual inspection after download.
• The creators advise caution for local-scale assessments, recommending use of confidence intervals at that scale.
• Row count and sample data are unknown, which may limit suitability assessment prior to download.
