Spectral and biochemical soil data
Listed in figshare and Loughborough Research Repository — shown once because both records carry DOI 10.6084/m9.figshare.33960217.v1
<p dir="ltr">The dataset comprised <b>73 soil samples</b> collected from four Amazonian floodplain ecosystems, including açaí agroforestry, low-floodplain, regenerated, and high-floodplain areas, across four soil depths.
Description
It combined laboratory measurements of <b>soil carbon stocks and β-glucosidase (BG) activity</b> with spectral data acquired using <b>VIS-NIR-SWIR (350–2500 nm) and mid-infrared (MIR) spectroscopy</b>.
These data were used to evaluate machine-learning approaches, particularly Random Forest and Support Vector Regression, for predicting soil carbon stocks and BG activity. Cross-validation was applied to assess model robustness and predictive performance. Overall, the dataset supports the development of rapid and cost-effective spectroscopy and machine-learning methods for monitoring <b>soil carbon and biological functioning in heterogeneous Amazonian floodplain soils</b>.</p>
