Mapping of soil properties and land degradation risk in Africa using MODIS reflectance


There is a need for up-to-date assessments and maps of soil properties and land health at scales relevant for decision-making and management, including for properties that are dynamic and hence change in response to management.

Rapid estimation of soil engineering properties using diffuse reflectance near infrared spectroscopy


Materials testing involve complex reference methods and several soil tests have been used for indexing material functional attributes for civil engineering applications. However, conventional laboratory methods are expensive, slow and often imprecise.

Quantification of total element concentrations in soils using total X-ray fluorescence spectroscopy (TXRF)


Total X-ray fluorescence spectroscopy (TXRF) determines concentrations of major and trace elements in multiple media. We developed and tested a method for the use of TXRF for direct quantification of total element concentrations in soils using an S2 PICOFOX™ spectrometer (Bruker AXS Microanalysis GmbH, Germany).
