Summary
This paper, published in Computers and Electronics in Agriculture, investigates the feasibility of using handheld XRF and NIR devices as rapid, low-cost alternatives to laboratory analysis for assessing nutrient content in crops or soils on-farm. The study likely reports validation data comparing portable sensor outputs against conventional analytical standards, offering insight into the practical precision and limitations of each technology. It contributes to the growing evidence base for precision agriculture tools that could support real-time nutrient management decision-making.
UK applicability
While the study's geographic focus is not confirmed, the technologies assessed — handheld XRF and NIR — are commercially available and increasingly relevant to UK precision farming contexts, including soil health monitoring under the Sustainable Farming Incentive and nutrient management planning requirements.
Key measures
Mineral nutrient concentrations (e.g. N, P, K, Fe, Zn, mg/kg); instrument accuracy metrics (e.g. RMSE, R²) compared to laboratory reference analysis
Outcomes reported
The study evaluated the accuracy and practical utility of handheld X-ray fluorescence (XRF) and near-infrared (NIR) spectrometers for measuring nutrient concentrations in crops or soils under on-farm conditions. It likely compared portable instrument readings against laboratory reference methods to assess reliability and precision.
