Soil Water Erosion [PDF]

open access: yesWater, 2022
Soil erosion by water is considered to be one of the major forms of soil degradation (other than soil erosion by wind, acidification, salinization, desertification, etc [...]

Water Erosion: Modeling

open access: yes, 2017
An outline is given to the development from earlier statistically based models of water-driven soil erosion to models designed to represent the physical processes involved. Examples of dynamic and steady-rate process models are also given.

Mapping erosion-corrosion of carbon steel in oil-water solutions : Effect of velocity and applied potential [PDF]

open access: yes, 2012
In this study, the combined effects of erosion and corrosion on carbon steel were investigated in three environments containing crude oil, reservoir water, and a mixture of both solutions at a range of applied potentials, velocities and impact angle. The

Erosion-corrosion maps for carbon steel in crude oil/water slurries : impact angle and applied potential effects [PDF]

open access: yes, 2010
In studies of erosion-corrosion, there have been few investigations into the effect of tribological issues, such as particle impact and impact angle, on erosion-corrosion of materials in oil field production.

Seed Pre-Soaking with Melatonin Improves Wheat Yield by Delaying Leaf Senescence and Promoting Root Development

open access: yesAgronomy, 2020
The effects of exogenous application of melatonin (MEL) on promoting plant growth and alleviating environmental stresses are already known, but the potential value in crop production is still poorly understood.

Single-Species Artificial Grasslands Decrease Soil Multifunctionality in a Temperate Steppe on the Qinghai–Tibet Plateau

open access: yesAgronomy, 2021
Artificial grasslands have been regarded as an effective method to improve grass production and quality, especially on the Qinghai–Tibet Plateau. Soil ecosystem multifunctionality (EMF) plays an important role in sustainable regional development. However,

Prediction of aboveground grassland biomass on the Loess Plateau, China, using a random forest algorithm

open access: yesScientific Reports, 2017
Grasslands are an important component of terrestrial ecosystems that play a crucial role in the carbon cycle and climate change. In this study, we collected aboveground biomass (AGB) data from 223 grassland quadrats distributed across the Loess Plateau ...
