The present study addresses the soil information gap in tropical seagrass meadows. The different geological and bioclimatic settings caused a relevant soil diversity. Contrasting geochemical conditions promote different intensities of soil processes. Seagrass soils from the NE semiarid coast are marked by a more intense sulfidization. Understanding soil processes may help in the sustainable management of seagrasses.

Our findings showed that the climatic, edaphic, plant and microbial variables jointly affected SIC stock in the Tibetan grasslands and that biotic factors had a larger contribution than abiotic factors to the variation of SIC stock. The effects of microbial and plant variables on SIC stock weakened with soil depth, while the effects of edaphic variables strengthened. The contrasting responses and drivers of SIC stock highlight differential mechanisms underlying SIC preservation with soil depth.

Our study examines different quantitative methods to predict concentrations of micronutrients in the soil from field samples. However, we emphasize the concerns of stakeholders, who use such information to make decisions, in this case in relation to the study and management of micronutrient deficiency risk in the human population. We propose a framework to think about these concerns then compare common approaches for digital soil mapping within this framework.

Adapting agricultural practices to future climatic conditions requires to synthesize the effects of management practices on soil properties with respect to local soil and climate. This study showcases different automated text processing methods to identify topics, extract metadata for building database and summarize findings from publication abstracts. While human intervention remains essential, these methods show great potential to support evidence synthesis from large number of publications.

We explored the effects of mild alternate wetting and drying (AWD) irrigation combined with rice straw return on N₂O emissions and rice yield through rice pot experiments. Mild AWD irrigation significantly increased N₂O emissions and yield-scaled N₂O emissions. The addition of rice straw under mild AWD irrigation could promote N₂O emission. Mild AWD irrigation could reduce soil nitrogen uptake by rice when urea was applied. Mild AWD irrigation reduced rice aboveground biomass but not rice yield.
