“…Lime application, in the form of slaked lime [Ca(OH) 2 ] and in a mixed form consisting of a blend of slaked lime [Ca (OH) 2 ] and calcium carbonate [CaCO 3 ], has been found to enhance the stability of aggregates in clayey soils (Blomquist et al 2017). The few studies that have assessed the effect of amendments on soil erodibility have not measured it directly, but rather have calculated erodibility based on its relation with other variables (Castro and Logan 1991;Ekwue 1992;Nishimura et al 2005;Özdemir et al 2015;Kumar et al 2019).…”

Good soil structure is important for achieving high productivity of agricultural land and also affects the ability of soil to withstand erosive forces. Given the importance of soil structure, efforts are commonly made to improve it, usually by application of amendments of different kinds (e.g. lime, biochar, compost, manure etc.). However, little is known about the effect of these amendments on the soil resistance to detachment. This study assessed the resistance to detachment of soil cores treated with different liming products, using a cohesive strength meter (CSM) which measures the rate of soil detachment under the action of water jets at different pressures. The amount of soil removed by the water jets was taken as an indirect measure of soil resistance to detachment, under the assumption that more resistant soils will lose less material than more susceptible soils at a given water jet pressure. The results showed that all soil amendments studied reduced detachment of particles under the action of water jets compared with unamended soil (control).

“…In this study, we did not find much difference between waste walnut wood and maize cobs to grounded powders < 0.5 mm and biochar made from the same materials. Though the effects of biochar and of grounded crop residue on soil aggregation has been studied intensively (Atkinson et al., 2010; Glaser et al., 2002; Jien & Wang, 2013; Kumar et al., 2019; Obia et al., 2016), their effects have not been compared before. Previous studies showed the presence of a small proportion of biochar particles in soil in the large macro‐aggregate fractions (>2 mm), as well as the role of biochar as a binding agent for organic matter in aggregate formation, protecting soil against degradation.…”

“…Moreover, these studies all focused on water erosion (e.g. Atkinson et al., 2010; Hammes & Schmid, 2009; Jien & Wang, 2013; Kumar et al., 2019). To date, no studies have been carried out to investigate the influence of biochar on wind erosion, particularly under arid and semi‐arid conditions.…”

Wind erosion mostly occurs in flat, bare areas, with dry, fine sandy to coarse silty soil or where the soil is loose and degraded. Soil degradation, including decline in soil quality caused by its improper use or poor management and soil erosion, has been considered as a major environmental issue in arid and semi-arid areas (Cornelis, 2006; Stroosnijder, 2007; Youssef et al., 2012). In arid areas, wind erosion is the main cause of erosion that leads to desertification. The extent of wind erosion, however, varies in different soils. Soil properties such as soil texture, structure, wetness, organic matter and aggregate stability affect the displacement of particles by wind. Long-term cultivation and intensive grazing decreases soil organic carbon and soil aggregate stability and increases its erosion potential (Obia, Mulder, Martinsen, Cornelissen, & Børresen, 2016). Various methods exist to stabilize soils, including biological, chemical, physical and mechanical stabilization methods. The effective addition of materials to degraded soils can

“…From an agricultural perspective, the addition of biochar in soil promotes crop yield and nutrient retention, which are widely established in several studies [20][21][22]. Concurrently, in geo-environmental applications, BAS were considered for its potential implementation on landfill liners and ground improvement in accordance with improvement on shear strength [23], better hydraulic performance [24], and mitigation of soil erosion [25]. Nevertheless the limitations of biochar such as leaching and toxicity were also added in the background of biochar studies [26,27].…”

Biochar has been recently investigated as an eco-friendly material in bio-engineered slopes/landfill covers. A majority of recent studies have focused on analyzing water retention behavior while very few have examined dynamic behavior (i.e., cyclic loading due to earthquake, wind, or wave) of biochar amended soil. As far as the authors are aware, there is no study on the dynamic behavior of biochar amended soils. Considering the above mentioned study as a major objective, field excavated soil was collected and mixed with in-house produced biochar from peach endocarps, at three amendment rates (5%, 10%, and 15%). The un-amended bare soil and biochar amended soil were imposed to a cyclic load in a self-designed apparatus and the corresponding stress-strain parameters were measured. Dynamic parameters such as shear modulus and damping ratio were computed and the results were compared between bare and biochar amended soil. Furthermore, the residual cyclic strength of each soil types were correlated with an estimated void ratio to understand the interrelation between dynamic loading responses and biochar amended soils. The major outcomes of this study show that the addition of biochar decreases the void ratio, thereby increasing the shear modulus and residual cyclic strength. However, the modulus and strength values attenuates after 15 cycles due to an increase in pore water pressure. In contrary, at higher amendment rates, Biochar Amended Soils (BAS) forms clay-carbon complex and decreases both shear modulus and residual cyclic strength.
