Investigations into the spatial dynamics of soil aggregate stability (AS) are urgently needed to better target areas that have undergone soil degradation. However, due to the lack of efficient alternatives to the conventional labor-intensive methods to quantify AS, detailed information on its spatial structure across scales are scarce. The objective of this study was to explore the possibility of using hyperspectral remote sensing imagery to ...

Soil erosion processes are affected by the erodibility of the soil and by the erosivity of the rain. The effects of rain characteristics and invariant soil properties such as texture and organic matter content on soil erosion processes are well documented. However, the effect of antecedent soil-water content (U+03B8a) on aggregate breakdown, seal formation and subsequent soil erosion is much more disputable as opposing effects have been ...

Soil aggregation results from the rearrangement, flocculation and cementation of soil particles, through the action of binding agents affected by soil characteristics such as organic carbon (OC), biota, ionic binding, clay and carbonates. However, there are other factors promoting the fragmentation, dispersion and degradation of aggregates, with soil surface sealing and crusting as a result. The objective of this study was to evaluate the effect ...

In order to evaluate the sustainability and efficiency of soil carbon sequestration measures and the impact of different management and environmental factors, information on soil organic matter (SOM) stability and mean residence time (MRT) is required. However, this information on SOM stability and MRT is expensive to determine via radiocarbon dating, precluding a wide spread use of stability measurements in soil science. In this paper, we test ...
