Site-Independent Mapping of Clay Content in Vineyard Soils via Mobile Proximal Gamma-Ray Spectrometry and Machine Learning Calibrations

Autor: Ralf Wehrle, Stefan Pätzold

Publikováno v: Sensors, Vol 24, Iss 14, p 4528 (2024)

Vineyards hold considerable soil variability between regions and plots, and there is frequently large soil heterogeneity within plots. Clay content in vineyard soils is of interest with respect to soil management, environmental monitoring, and wine q

Total and Hot-Water Extractable Organic Carbon and Nitrogen in Organic Soil Amendments: Their Prediction Using Portable Mid-Infrared Spectroscopy with Support Vector Machines

Autor: Ralf Wehrle, Gerhard Welp, Stefan Pätzold

Publikováno v: Agronomy, Vol 11, Iss 4, p 659 (2021)

Against the background of climate change mitigation, organic amendments (OA) may contribute to store carbon (C) in soils, given that the OA provide a sufficient stability and resistance to degradation. In terms of the evaluation of OA behavior in soi

Portable mid-infrared spectroscopy to predict parameters related to carbon storage in vineyard soils: Model calibrations under varying geopedological conditions

Autor: Ralf Wehrle, Guillaume Coulouma, Stefan Pätzold

Publikováno v: Biosystems Engineering
Biosystems Engineering, 2022, 222, pp.1-14. ⟨10.1016/j.biosystemseng.2022.07.012⟩

International audience; Portable mid-infrared spectroscopy (pMIRS) combined with machine learning was used to predict selected parameters for soil organic carbon (SOC) storage. In particular, SOC, soil inorganic C (SIC), hot-water extractable C (hwC)

Investigating the potential of vineyard soils for carbon sequestration and greenhouse gas emission mitigation after incorporation of organic matter into the subsoil

Autor: Muhammad Saiful Islam, Stefan Pätzold, Ralf Wehrle, Nele Bendel, Katja Herzog, Nicolas Brüggemann

Soils in perennial cropping systems, such as vineyards, have good prospects for storing carbon since less management is required with minimum disturbance to the soil that might prevent rapid turnover of organic matter. In addition, incorporation of o
