Disentangling the Roles of Microbial Traits and Mineral Protection in Regulating Temperature Sensitivity of Soil Carbon Decomposition in Eroded and Depositional Agricultural Soils

Earth's Future
The temperature sensitivity of soil organic carbon decomposition (Q10) governs the fate of soil carbon under global warming. Although erosion redistributes soil carbon at scales comparable to the terrestrial carbon sink, how erosion reshapes Q10 across ...

Effectiveness of exclosures to control soil erosion and local communities perception on soil erosion [PDF]

, 2009
The study investigated how effective exclosures are in the fight against soil erosion and how they are perceived as a means to control soil erosion by the local community (farmers and local experts).

On the evaluation of soil erosion models: Are we doing enough?

Earth-Science Reviews, 2019
As any model of real-world phenomena, soil erosion models must be tested against empirical evidence to have their performance evaluated. This is critical to develop knowledge and confidence in model predictions. However, evaluating soil erosion models is

Interactions between Molten High‐Silicon Electrical Steels and Carbon‐Bonded MgO Refractories Based on Recyclates

Advanced Engineering Materials, EarlyView.
This study examines how several molten high‐silicon electrical steels interact with both conventional and recycled MgO–C refractories. For this, various immersion experiments are conducted. In addition to infiltration, a number of mechanisms are identified and explained that control the corrosion of the refractory material.

The relationships and sensibility of wheat C:N:P stoichiometry and water use efficiency under nitrogen fertilization

Plant, Soil and Environment, 2015
A field study was conducted to investigate the variations in the carbon:nitrogen:phosphorus (C:N:P) stoichiometry of winter wheat (Triticum aestivum L.) and its relationships with wheat growth rate (r) and water use efficiency (WUE) under different rates

Some reflections on a model to predict the erosion rate of the passive film on pure metals [PDF]

, 2009
A model to predict the erosion rate of the passive films on metals is proposed. The model investigates the effect of eroded particles on a metal on which a passive (oxide) film has formed. To date, many of the existing erosion models have concentrated on

The Physics of Protoplanetesimal Dust Agglomerates. Vi. Erosion of Large Aggregates as a Source of Micrometer-Sized Particles

, 2011
Observed protoplanetary disks consist of a large amount of micrometer-sized particles. Dullemond and Dominik (2005) pointed out for the first time the difficulty in explaining the strong mid-IR excess of classical T-Tauri stars without any dust-retention

Improving water-use efficiency by decreasing stomatal conductance and transpiration rate to maintain higher ear photosynthetic rate in drought-resistant wheat

Crop Journal, 2017
In wheat, the ear is one of the main photosynthetic contributors to grain filling under drought stress conditions. In order to determine the relationship between stomatal characteristics and plant drought resistance, photosynthetic and stomatal ...
