TerraMap produces the world’s highest resolution soil maps

Mapping layers at over 800 data points per hectare, TerraMap enables agronomists and growers to make the most of precision technology.

TerraMap high resolution soil mapping

TerraMap uses passive, gamma-ray detection technology, providing high-definition mapping of all common nutrient properties, pH, soil texture, organic matter and CEC as well as elevation and plant available water.

It measures naturally emitted isotopes, like Caesium and Potassium, that are very stable due to their long half-lives.

The significance of this methodology is that it is not affected by soil moisture, compaction, crop cover or cultivation state.

This means that there are very few limitations to when TerraMap can be used – offering a much wider operating window for soil scans compared to other soil scanning systems, and the consistency and reliability of the results from TerraMap are proven across many years and hectares.

TerraMap soil mapping is not affected by soil moisture, compaction, crop cover or cultivation state.

Gamma-ray detection technology maps all of the common nutrient and physical soil properties.

Measures Four Naturally Emitted Isotopes

The TerraMap system uses gamma-ray detection technology to map all of the common nutrient and physical soil properties.

The scanner, which is manufactured by Canadian company SoilOptix measures four naturally emitting isotopes:

  • Caesium-137 (C)
  • Uranium-238 (U)
  • Potassium-40 (K)
  • Thorium-232 (Th)

800 Reference Points Per Hectare

TerraMap produces the highest resolution soil mapping layers in the world at over 800 data reference points per hectare.

In comparison, grid sampling map layers have only a single data point per hectare.

Soil Samples Taken and Data Processed

The in-field process of collecting the data is carried out in two very simple steps; scanning and collecting reference soil samples.

The raw scan data and soil samples are then combined and processed to produce up to 21 high-definition soil property layers.

TerraMap is available as a Standard or Premium service

The Standard service measures 9 criteria: P, K, Mg, pH and % of clay, sand, silt, texture and elevation.

In addition to these, the Premium service also measures calcium, sodium, manganese, boron, copper, molybdenum, iron, zinc, sulphur, OM, CEC and plant available water, delivering 21 layers of data for each field.
