“…In addition, the soil loss amount at the layers of 12-30 cm above the surface was similar among the treatments in the present study. This result was in agreement with the fact that the application of plant residual to soil can stabilize soil against soil erosion (He et al, 2017;Pi et al, 2018). Thus, as the thickness of soil incorporated residual increased, the soil loss amount reduced rapidly, especially for 0-9 cm above the surface, accounting for 84.6% of the total.…”

Plant residual is of great importance in retarding soil wind erosion in the agro-pastoral ecotone. However, few studies have determined the effects of sand plant residual on wind erosion resistance. Based on field surveys, the influences of Salix residual biomass of 200, 400, 600, and 800 g m−2, soil incorporated with a residual thickness of 0.5, 1.0, and 2.0 cm, and typical proportion of residual branches and leaves (2:1, 1:1, and 1:2) on wind erosion resistance were investigated using a simulated wind tunnel. The results showed the following: 1) The soil loss amount ranged from 1.56 to 40.8 kg m−2 as Salix residual biomass decreased from 800 to 0 g m−2, with a critical residual biomass value of 400 g m−2. 2) As the thickness of soil-incorporated residual increased, the soil loss amount reduced rapidly, especially for 0–9 cm above the surface accounting for 84.6% of the total. 3) Salix branch residual is more important in resisting soil wind erosion as compared with its leaves. This kind of study may provide theoretical explanations for the optimal reconstruction of sandy vegetation in the northern wind-sand regions.

“…The approximate abrader rate for this tunnel is around 0.5 g m −1 s −1 , which is representative of soil flux during extreme high winds on the Columbia Plateau region (Sharratt & Schillinger, 2014). The saltating and suspended sediments up to a height of 0.75 m above the surface were sampled downwind of the tray using a vertically integrating isokinetic slot sampler (Pi et al, 2018). The particle size distribution of the collected samples was determined using a laser diffraction particle size analyzer (LS 13 320, Beckman Coulter, Brea, CA, USA).…”

Large-scale soil application of biochar is one of the terrestrial carbon sequestration strategies for future climate change mitigation pathways, which can also help remove and sequester pollutants from contaminated soil and water. However, black carbon emissions from biochar-amended soils can deteriorate air quality and affect human health, as the biochar particles often contain a higher amount of sorbed toxic pollutants than the soil. Yet, the extent and mechanism of inhalable particulate matter (PM 10) emission from biochar-amended soils at different wind regimes have not been evaluated. Using wind tunnel experiments to simulate different wind regimes, we quantified particulate emission from sand amended with 1-4% (by weight) biochar at two size fractions: with and without <2-mm biochar. At wind speeds below the threshold speed for soil erosion, biochar application significantly increased PM 10 emission by up to 400% due to the direct resuspension of inhalable biochar particles. At wind speeds above the threshold speed, emission increased by up to 300% even from biochar without inhalable fractions due to collisions of fast-moving sand particles with large biochar particles. Using a theoretical framework, we show that particulate matter emissions from biochar-amended soils could be higher than that previously expected at wind speeds below the erosion threshold wind speed for background soil. Our results indicate that current models for fugitive dust emissions may underestimate the particulate matter emission potential of biochar-amended soils and will help improve the assessment of biochar emission from amended soils.

“…This effect is probably due to the progressive disaggregation of soil aggregates that have been proven to affect PM10 emissions (Madden et al, 2010). The effect of tillage on windblown dust and PM emissions was also shown to be affected by the implement choice (Lopez et al, 1998;Pi et al, 2018;Singh et al, 2012), being for example higher with disking that with under cutter tillage (Pi et al, 2018).…”
