Soil Grids of Victoria: Soil pH Predictions at 90-Meter Resolution

A 2026-updated set of digital soil maps for the state of Victoria, produced by the Department of Energy, Environment and Climate Action. The dataset provides mean, 5th, and 95th percentile prediction values for soil pH (in a 1:5 soil-water solution) across six depth intervals, from 0-5 cm to 100-200 cm. The grids are designed to meet GlobalSoilMap specifications and are based on methodology refined by the Australian Soil and Landscape Grid.

Use Cases

• Modeling agricultural productivity based on soil pH predictions across different depths.
• Informing land use policy and planning based on spatially interpolated soil property grids.
• Supporting ecosystem modeling based on detailed, continuous estimates of soil attributes.
• Assessing regional soil trends and pedogenesis based on raster data with confidence intervals.

Strengths

• Provides predictions at a 90-meter grid resolution, offering fine-scale spatial detail.
• Includes confidence intervals (5th and 95th percentile values) for each prediction.
• Covers six standard depth intervals, enabling vertical profile analysis.
• Follows the consistent methodological specifications of the GlobalSoilMap project.

Limitations

• The description advises caution for local-scale assessments, recommending use of confidence intervals at that scale.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for some analytical tasks.
