Background Topographic depressions within agricultural fields contribute disproportionately to regional nitrous oxide (N 2 O) emissions. These low-lying areas accumulate nutrients and fine particles through water inflow and erosion, creating conditions conducive to elevated N 2 O emissions. Because depressions remain part of fields, understanding how crop presence and management influence their N 2 O source strength is essenti...

Background and aims Thallium is a non-essential trace element occurring as a contaminant from industrial pollution, but it is also economically valuable. Phytoextraction for thallium using hyperaccumulator plants offers a potential opportunity to remediate thallium-contaminated soil while obtaining a valuable product (then called 'phytomining'). Silene latifolia is among the most promising candidates for thallium phytomining,...

Aims Although there is increasing evidence that the storage of soil organic carbon (SOC) is affected by woody plant encroachment in savannas, the underlying physical stabilization mechanisms controlling SOC partitioning among aggregate fractions remain poorly resolved, particularly in sandy soils. We assessed changes in SOC concentration and SOC stocks (SOCs), soil water‑stable aggregates, and physical protection mechanisms wi...
