Calibrated SoilOptix ® estimates of soil pH and exchangeable cations in three agricultural fields in western Canada – | This study focusses on how gamma-ray sensor-estimated soil pH and associated properties can be used for agricultural management. “We conclude that proximal soil sensors can be calibrated to soil properties, enabling variable rate lime recommendations on spatially variable fields for the management of soil acidity.” | 2024 |
Findings show the potential for using this portable gamma sensor for rapid spatial analysis of TC and TN across agricultural land units. | 2023 | |
An independent overview of performance of different proximal soil sensing technologies. It point how gamma-ray sensors are highly valuable for producing soil maps and delineating management zones at field scale. The strength of gamma-ray spectromettry lies in capturing spatial patterns, as radionuclide distributions correlate with key soil properties such as texture, soil carbon and nutrients. | 2026 | |
A systematic comparison of proximal soil sensing technologies for high-resolution soil property prediction and mapping. Field experiments demonstrate that gamma-ray spectroscopy is one of the most effective single sensors for predicting key soil properties across heterogeneous agricultural soils, . | 2024 | |

Multi Sensor Soil Sensing Tool for Farmland in Spain 2016 Multi Sensor Soil Sensing Tool for Farmland in Spain.pdf | Medusa developed an efficient and effective soil sensing system (gamma-ray and GPR) on a 4x4 car to be able to measure >100 fields, 300 ha throughout the north of Spain in 3 weeks. The sensing data was combined with open data (DEM, geology) and soil sampling results (by UPM) to acquire information about soil texture, soil organic matter, tillage layer depth, compaction, altitude, slope, nutrients. This provided a good understanding of the soils and is a powerful communication tool for farmers and agronomists. This paper was presented at the EAGE near surface conference in Barcelona, 2016 | 2016 |
Mapping soil clay contents in Dutch marine districts using gamma-ray spectrometry | At field scale, gamma-ray spectrometry predicts clay content with an error of 2–3%. In the Netherlands, the fingerprinting of clays should be considered within geological regions. | 2011 |
