Soil Property Effects on Wind Erosion of Organic Soils

International Symposium on Erosion and Landscape Evolution (ISELE), 18-21 September 2011, Anchorage, Alaska, 2011
Abstract Histosols (also known as organic soils, mucks, or peats) are soils that are dominated by organic matter (OM > 20%) in half or more of the upper 80 cm. Forty two states have a total of 21 million ha of Histosols in the United States. These soils, when intensively cropped, are subject to wind erosion resulting in loss of crop productivity and ...

Soil Erosion by Wind

1989
Excerpts from the report: Accelerated soil erosion by wind is the most dramatic form of soil erosion. It was the dust storms of the 1930’s that focused national attention on the problem of soil erosion. This bulletin details the scope of erosion by wind in the United States, describes the conditions that allow erosion, and shows how hundreds of ...

WIND EROSION OF CRUSTED SOIL SEDIMENTS

Earth Surface Processes and Landforms, 1996
Saltating particles increase the rate of dust release from sediments in arid and semi-arid areas. They also break interparticle bonds in aggregated and crusted soils, thereby increasing the number of particles available for entrainment. This pilot study examines rates of erosion in relation to the flux of saltating grains for three crusted sediments of

Wind Erosion of Soils Burned by Wildfire

International Symposium on Erosion and Landscape Evolution (ISELE), 18-21 September 2011, Anchorage, Alaska, 2011
Wind erosion and aeolian transport processes are largely unstudied in the post-wildfire environment, but recent studies have shown that wind erosion can play a major role in burned landscapes. A wind erosion monitoring system was installed immediately following a wildfire in southeastern Idaho, USA to measure wind erosion from the burned area (Figure 1)

Soil Losses by Wind Erosion

Soil Science Society of America Journal, 1995
Abstract Measurements of wind erosion from fields are limited, but with recently developed erosion samplers, it is possible to determine soil losses from natural winds. Erosion of soils by wind was measured in five states.

Soil Cover and Wind Erosion

Transactions of the ASAE, 1985
ABSTRACT WIND erosion on agricultural lands can be reduced if the soil surface is protected with crop residues. In evaluating the influence of residues on wind erosion, previous research has expressed residues of various crops as an equivalent of flat, small grain.

Automated system for soil wind erosion studies

Computers and Electronics in Agriculture, 2019
Abstract Wind erosion is a natural soil degradation process that threatens agriculture in many locations. We have used several different methods, including wind tunnels, to analyze this type of soil erosion. In this paper we present a new wind tunnel design that enables very simple analysis of soil wind erosion.

Soil Ridges-Clods and Wind Erosion

Transactions of the ASAE, 1984
ABSTRACT A portable wind tunnel was used to evaluate soil losses in 10 minutes from a flat surface, and from ridges 63 to 254 mm high when 0 to 60% of the soil surface was covered with nonerodible clods. Soil losses were reduced 90% with soil ridges 63 to 254 mm high, 89% with nonerodible soil clods covering 60% of the soil surface, and 98% with a ...
