Dept of Environment, Water and Natural Resources - Soil Salinity - Non-watertable (magnesia patches)

공공데이터포털

Non-watertable salinity (or dry saline land) is where soil contains elevated levels of soluble salts that are not associated with a watertable. Magnesia patches occur where high concentrations of this salt extend to the surface and visibly affect plant growth. Mapping shows the proportion of land affected by magnesia patches, while detailed proportion data are supplied for calculating total areas of affected land (spatial data statistics).

Dept of Environment, Water and Natural Resources - Soil Water Repellence

공공데이터포털

Water repellence, or non-wetting, due to coating of soil particles by waxy materials from the breakdown of plant debris can result in water beading on the surface, uneven wetting and large masses of soil remaining dry. Mapping shows the proportion of land affected and degree of water repellence, while detailed proportion data are supplied for calculating respective areas of each water repellence class (spatial data statistics).

Dept of Environment, Water and Natural Resources - Depth to Watertable (soils)

공공데이터포털

Depth to watertable mapping highlights land where watertables may be sufficiently shallow on a seasonal basis to affect plant growth. It is intended to describe soil conditions for plant suitability and is not intended to be a literal map of watertable levels, which will change over time. Mapping shows the shallowest depth to watertable observed (provided it accounts for at least 30% of the map unit), while detailed proportion data are supplied for calculating respective areas of each depth to watertable class (spatial data statistics).

Dept of Environment, Water and Natural Resources - Soil Waterlogging Susceptibility

공공데이터포털

Waterlogging susceptibility describes the degree and duration of impact to soils, and hence plants, arising from poor drainage. Mapping indicates the most severely waterlogged areas (provided they occupy at least 30% of a map unit), while detailed proportion data are supplied for calculating respective areas of each waterlogging susceptibility class (spatial data statistics).

Dept of Environment, Water and Natural Resources - Soil Rootzone Depth Potential CA - Sensitive horticultural crops (e.g. citrus, avocado)

공공데이터포털

Potential rootzone depth for irrigated horticultural crops is affected by a range of soil parameters (e.g. soil physical condition, hard rock or hardpan, soluble salts, boron concentrations, alkalinity, acidity and sodicity). Mapping shows the estimated average potential rootzone depth for sensitive crops (e.g. citrus, avocado), while detailed proportion data are supplied for calculating respective areas of each rootzone depth potential class (spatial data statistics).

Dept of Environment, Water and Natural Resources - Flooding Susceptibility (soils)

공공데이터포털

Susceptibility to flooding imposes a serious limitation on land especially where infrastructure is required. Mapping shows the proportion of land susceptible to flooding, while detailed proportion data are supplied for calculating total areas of susceptible land (spatial data statistics).

Dept of Environment, Water and Natural Resources - Scalding (soils)

공공데이터포털

Scalding refers to land, primarily in low rainfall environments, where the surface soil has been eroded to expose sub-surface material that is unsuited to plant growth. Mapping shows the proportion of land affected by scalding, while detailed proportion data are supplied for calculating total areas of affected land (spatial data statistics).

Dept of Environment, Water and Natural Resources - Acid Sulfate Soil Potential

공공데이터포털

Acid sulfate soil potential mapping shows the proportion of land susceptible to the development of acid sulfate soils, while detailed proportion data are supplied for calculating respective areas of each acid sulfate soil potential class (spatial data statistics).

Dept of Environment, Water and Natural Resources - Soil Rootzone Depth Potential CE - Above ground annual crops (e.g. brassicas)

공공데이터포털

Potential rootzone depth for irrigated horticultural crops is affected by a range of soil parameters (e.g. soil physical condition, hard rock or hardpan, soluble salts, boron concentrations, alkalinity, acidity and sodicity). Mapping shows the estimated average potential rootzone depth for above ground annual crops (e.g. brassicas), while detailed proportion data are supplied for calculating respective areas of each rootzone depth potential class (spatial data statistics).
