Tamba, Yvonne; Chacha, Robin; Mboi, Damaris; Aynekulu, Ermias; Luedeling, Eike; Shepherd, Keith, 2022, "Dataset for supporting the net agronomic assessment of yield limiting factors in maize production in Machakos county, Kenya", https://doi.org/10.34725/DVN/KKHVOF, World Agroforestry (ICRAF), V1, UNF:6:QZ+UN2QU5x8NcdqNy+AySg== [fileUNF]
This dataset is used for a holistic analysis of the costs, benefits, and risks of on-farm soil and plant health management. The dataset was produced in 2017 by a combination of field measurements and farmer surveys. It was collected for a research study aimed at identifying and t...

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; Lee Drake, B, 2016, "Replication data for: Plant elemental composition and portable X-ray fluorescence (pXRF) spectroscopy: quantification under different analytical parameters", https://doi.org/10.34725/DVN/WGWE8S, World Agroforestry (ICRAF), V1
Emergence of portable X-ray fluorescence (pXRF) systems presents new opportunities for rapid, low-cost plant analysis, both as a lab system and in situ system. Numerous studies have extolled the virtues of using pXRF for a wide range of plant applications, however, formany such a...
