Overview

TerraMap produces the world’s highest resolution mapping layers at over 800 data points per hectare enabling agronomists and growers to make the most of precision technology.

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 compared to other soil scanning systems and the consistency and reliability of the results from TerraMap are proven across many years and hectares.

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) and Thorium-232 (Th).

TerraMap Data Reference Points - 800 per hectare

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.

TerraMap Soil Samples - referenced with raw scan data to calculate soil property layers

Soil Samples
Taken and
Data Processed

The infield 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, manganese, boron, copper, molybdenum, iron, zinc, sulphur, OM, CEC and plant available water, delivering 21 layers of data for each field.
