Replacement of fallow in crop–fallow systems with cover crops (CCs) may improve soil properties. We assessed whether replacing no‐till winter wheat ( Triticum aestivum L.)–fallow and spring CCs for 5 yr reduced wind water erosion, increased organic carbon (SOC), improved physical properties on a Ulysses silt loam (fine‐silty, mixed, superactive, mesic Aridic Haplustolls) the semiarid central Great Plains. Winter triticale (× Triticosecale Wittm.), lentil Lens culinaris Medik.), lentil, pea...
Wind erosion and blowing dust threaten food security, human health ecosystem services across global drylands. Monitoring wind is needed to inform management, with explicit monitoring objectives being critical for interpreting translating information into management actions. should establish quantitative guidelines determining the relationship of indicators benchmarks that reflect tolerable production levels considering impacts to, example, processes, species, agricultural systems well-being....
Addition of cover crops and animal manure following corn (Zea mays L.) stover removal for expanded uses may mitigate negative soil property effects removal. We studied the short-term (3 yr) cumulative impacts with without winter rye (Secale cereale crop or application on near-surface (0- to 5-cm depth) properties under irrigated no-till continuous a Hastings silt loam (fine, smectitic, mesic Udic Argiustolls) (<3% slope) near Clay Center, NE. Treatments were irrigation levels (full deficit),...
Wind erosion is a major resource concern for rangeland managers because it can impact soil health, ecosystem structure and function, hydrologic processes, agricultural production, air quality. Despite its significance, little known about which landscapes are eroding, by how much, when. The National Erosion Research Network was established in 2014 to develop tools monitoring assessing wind dust emissions across the United States. Network, currently consisting of 13 sites, creates...
Climate change may impact soil health and productivity as a result of accelerated or decelerated rates erosion. Previous studies suggest greater risk wind erosion on arid semi-arid lands due to loss biomass under future warmer climate. There have been no conducted assess the climate in Columbia Plateau Pacific Northwest United States where agricultural can cause exceedance national air quality standards. The Wind Erosion Prediction System (WEPS) was used PM10 (particulate matter ≤10 µm...
ABSTRACT Inducing biological soil crust (biocrust) development is an appealing approach for dust mitigation in drylands due to the resistance biocrusts can provide against erosion. Using a portable device, we evaluated emissions from surfaces either inoculated with biocrust, amended plant‐based stabilizer, or both at varying wind friction velocities. Four months after application, all treatments were indistinguishable greater than controls, despite evidence of biocrust establishment. All had...
ABSTRACT The purpose of this study was to develop a wind simulator furnish direction and sub-hourly speed users information, particularly for erosion modeling. We analyzed the Wind Energy Resource Information System data determine scale shape parameters WeibuU distribution each 16 cardinal directions month at 704 locations in United States. also summarized distributions, ratio daily maximum minimum speed, hour by location. This summary historical statistics constitutes compact base...
Aeolian processes are fundamental to arid and semi-arid ecosystems, but modeling approaches poorly developed for assessing impacts of management environmental change on sediment transport rates over meaningful spatial temporal scales. For model estimates provide value, flux that encapsulate intra- inter-annual variability needed. Further, it is important quantify communicate transparent uncertainty users. Here, we present a wind erosion dust emission parameterized rangelands using...
ABSTRACT WINDBREAKS, although beneficial for wind erosion control, compete with crops space and soil water. Soil profile water content, measured along perpendicular transects adjacent to single-row windbreaks of tamarisk, Siberian elm, Russian-olive, honeysuckle, peashrub near Colby, Kansas (1978-1982), was significantly different distance in 6 15 sampling dates. data from several dates suggested that tamarisk is the highest user lowest among species (honeysuckle omitted). Half windbreak...
Dedicated bioenergy crops such as perennial warm‐season grasses (WSGs) may reduce soil erosion and improve properties while providing biomass feedstock for biofuel. We quantified impacts of WSGs row on wind erodibility parameters (erodible fraction, geometric mean diameter dry aggregates, aggregate stability) organic carbon (SOC) concentration under a dedicated crop experiment in eastern Kansas after 4 5 yr management. Soil were measured switchgrass ( Panicum virgatum L.), big bluestem...
Core Ideas Corn residue baling increased the wind‐erodible fraction relative to no baling. Cattle grazing of corn residues had smaller effects on wind erosion than As cover decreased, increased. Soil erodibility decreased as particulate organic matter Simulated soil loss showed that potential. Implications ( Zea mays L.) and in integrated crop–livestock systems are not well understood. This study (i) determined properties affecting potential including dry aggregate‐size distribution,...
Wind is the principal driver of Erosion Prediction System (WEPS), which a process-based computermodel for simulation wind-blown sediment loss from field. WEPS generates wind using stochastic generator.The objectives this study were to improve generation speed and direction update windstatistics used by generator with statistics derived more recent, quality-controlled data 48 contiguous statesof U.S. Erosive power density (WPD) was chosen evaluate how well generated, since it proportionalto...
