Towett, Erick; Shepherd, Keith; Sila, Andrew; Aynekulu, Ermias; Cadisch, Georg, 2016, "Mid-infrared and total X-ray fluorescence spectroscopy complementarity for assessment of soil properties", https://doi.org/10.34725/DVN/N0UGWL, World Agroforestry (ICRAF), V1, UNF:6:Ft32jdT6CrFszNC2Ig68Mw== [fileUNF]
Diffuse reflectance Fourier transformed mid-infrared (DRIFT-MIR) spectroscopy can predict many soil properties but extractable nutrients are often predicted poorly. This paper tested the combined DRIFT-MIR and total X-ray fluorescence (TXRF) spectroscopy analysis for prediction o...

Towett, Erick; Shepherd, Keith; Tondoh, Jerome; Winowiecki, Leigh; Lulseged, Tamene; Nyambura, Mercy; Sila, Andrew; Tor-G., Vågen; Cadisch, Georg, 2016, "Total elemental composition of soils in Sub-Saharan Africa and relationship with soil forming factors", https://doi.org/10.34725/DVN/4VOYZW, World Agroforestry (ICRAF), V1, UNF:6:Rxqr/SZyZSF+hgyMX5GpCg== [fileUNF]
A thorough understanding of the variation in total soil element concentrations is important especially in the Sub-Saharan Africa (SSA) soil contexts for agricultural and environmental management at large scale. Fingerprinting of soil elemental composition may form a useful basis...

Towett, Erick; Shepherd, Keith; Sila, Andrew; Chacha, Robin, 2014, "Replication data for: Quantification of total element concentrations in soils using total X-ray fluorescence spectroscopy (TXRF)", https://doi.org/10.34725/DVN/24294, World Agroforestry (ICRAF), V2
Total X-ray fluorescence spectroscopy (TXRF) determines concentrations of major and trace elements in mul- tiple 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 TM spectrometer (Bru...

Olale,Kennedy; Yenesew, Abiy; Jamnadass, Ramni; Sila, Andrew; Aynekulu, Ermias; Kuyah, Shem; Shepherd, Keith, 2014, "Replication data for: Limitations to use of infrared spectroscopy for rapid determination of carbon-nitrogen and wood density for tropical species", https://doi.org/10.34725/DVN/24522, World Agroforestry (ICRAF), V2
Infrared (IR) spectroscopy was used as a rapid and non-destructive method to determine, carbon (C), nitrogen (N) and tree wood density.A total of 82 sample cores were scanned in the reflectance mode from 4000 to 400 cm-1 for mid-infrared (MIR) spectra and from 8000 to 4000cm-1 an...
