Abstract:
... Investigators are debating on the positive and negative priming effects of biochar on native soil organic carbon (SOC), which is largely attributed to the technical barrier of identifying biochar contribution to the apparently measured SOC or mineralized CO₂. We combined benzene polycarboxylic acids (BPCAs) molecular biomarkers and soil particle density fractionation to identify biochar contributi ...

There are relatively few studies that explicitly evaluate the performance of machine learning algorithms (MLAs) such as decision trees while varying conditions like data splitting strategies and feature selection methods in digital soil mapping (DSM). Since several more powerful black-box models such as Random Forest (RF) exist, regular models like the Classification and Regression Tree (CART) are ...

Abstract:
... Soil organic matter (SOM) decomposition and stabilisation are largely affected by microbial carbon use efficiency (CUE), which is defined as the proportion of substrate carbon (C) uptake that microbes use for growth. Microbial CUE varies due to substrate quality and availability differences, but this may also depend on soil properties, such as pH, soil organic C (SOC) and clay content. We conducte ...

The response of soil organic carbon (SOC) dynamics to nitrogen enrichment in the scale of whole-soil profiles, especially in deeper soil layers containing approximately half of SOC, remains unclear. Here, the incorporation of new vegetation-derived carbon into whole-soil profiles is estimated by combining natural stable isotopes (¹³C and ¹⁵N) with radiocarbon analyses under elevated nitrogen input ...
