Abstract:
... Knowledge of surface roughness with the consequent presence of crust in the soil is important information for the rational management of environmental resources. Soil surface roughness can be determined by contact and noncontact methods. Contact methods have lower values and precision than noncontact methods. Therefore, the objective of this study was to develop low-cost, portable and robust optic ...

Yet how plants influence the responses of soil microbes to climate warming remains largely unknown. In this study, a field warming experiment using infrared heaters was conducted on the eastern Tibetan Plateau to investigate ...

Abstract:
... The accuracy of digital soil maps (DSMs) is influenced by the quality of the input data. The application of legacy data obtained from past soil surveys was considered a potential method to improve DSM input data. However, changes in soil classification systems have occurred in many countries, and legacy data are therefore not directly applicable in the generation of the latest DSMs. This research ...

Abstract:
... High-quality plant inputs to the soil with low lignin to nitrogen ratios have been conceptualized to foster the formation of soil organic matter (SOM) and carbon (C) in stabilized soil compartments, such as aggregates and organo-mineral associations (MAOM), in dependence of the soil’s capacity to store additional C (i.e., C saturation deficit). Yet, evidence for these conceptualizations from field ...
