“…In the present study, the significantly increased soil EC and mesopores proportion by biochar addition might be the two important reasons for the reduction in alfalfa yield, based on the stepwise linear regression analysis (Table S2). In terms of the increased EC, many studies have found that biochar addition resulted in higher soil EC as the ash of biochar contains some salt ions (Araújo Santos et al, 2022; Farhangi‐Abriz & Torabian, 2017; Fernandes et al, 2019; Gavili et al, 2019; Huang et al, 2019; Lee et al, 2022; Luo et al, 2017; Thomas et al, 2013). Moreover, Gavili et al (2019) found cattle manure biochar addition rates at 2.5% and 5% increased soil EC, leading to the adverse influence on soybean growth.…”

“…Moreover, Gavili et al (2019) found cattle manure biochar addition rates at 2.5% and 5% increased soil EC, leading to the adverse influence on soybean growth. In addition, the small particle biochar used in this study could fill soil macropores and convert them to mesopores, which led to higher soil water holding capacity and further adversely affected crop growth through inhibiting crop water uptake in saline soils (Araújo Santos et al, 2022; Brtnicky et al, 2021; Głąb et al, 2016; Villagra‐Mendoza & Horn, 2018). Higher SWC was found after each harvest under biochar treatments in this study seems to confirm that larger water holding capacity for soils after biochar addition limited root water uptake.…”

Biochar addition has been proven to have great potential for improving soil physicochemical properties and crop growth in salt‐affected soils. However, whether adding biochar could affect alfalfa growth and soil bacterial community in salt‐affected soils of arid regions remains poorly understood. A pot experiment was carried out to investigate the effects of corn straw biochar addition on soil physicochemical properties, bacterial community and alfalfa yield in saline soils. There were 12 treatments in total, combining three biochar addition rates of 0, 20 and 40 g kg−1 (referred to as B0, B2 and B4, respectively) and four salinity levels of 0, 2, 4 and 6 g kg−1 (referred as to S0, S2, S4 and S6, respectively). The results indicated that biochar addition significantly increased soil organic carbon (SOC), electrical conductivity (EC), soil water content (SWC), available nitrogen (AN) and phosphorus (AP) and mesopores fraction, but decreased soil bulk density (BD), pH and macropores fraction for different salinity levels. In general, biochar addition had an adverse effect on alfalfa yield due to the aggregated stresses from the increased EC and mesopores fraction, especially at high salinity levels. On average, biochar addition decreased the total yield of the two years by 14.2%, 25.3%, 38.3% and 60.4% for S0, S2, S4 and S6, respectively. Biochar addition significantly changed bacterial community composition with higher relative abundances of Proteobacteria and Bacteroidetes but lower relative abundances of Actinobacteria and Acidobacteria under S2–S6. On average, both soil salinity and biochar treatments decreased soil bacterial richness by 5.7–14.6% and 4.1–8.8% compared with S0 and B0, respectively, but they did not significantly affect the bacterial diversity. The redundancy analysis (RDA) suggested that EC, SWC, pH, AN and AP were the most critical factors driving the change of soil bacterial community structure accounting for 69.9%, 64.7% 61.6%, 57.0% and 51.8% of the variation, respectively. Therefore, our results provided valuable insight into how biochar addition would affect alfalfa yield and soil properties, including bacterial community richness and composition and structure of saline soils in arid regions.

The access of vinasse leachates to water bodies and groundwater exacerbates environmental problems, especially eutrophication. Therefore, a column experiment was performed to examine the effect of adding zeolite (ZL), bone char (BC), and wood chips biochar (WCB) in the presence of vinasse on carbon dioxide (CO2) emission, leaching dissolved organic carbon (DOC) and ammonium (NH4+) in calcareous sandy soil, as well as studying the kinetics of leaching dissolved organic carbon and ammonium. This column experiment contains four treatments: soil alone (CK), soil + zeolite (SZL), soil + bone char (SBC), and soil + wood chips biochar (SWCB). These amendments were applied to the soil at a level of 4%. Vinasse was added to all treatments at a level of 13 mL per column. The leached total cumulative DOC and total cumulative soluble ammonium amounts decreased significantly with applying ZL, BC, and WCB compared with the soil alone. The effectiveness of these amendments in lowering the total cumulative DOC leaching is in the order of SBC > SWCB > SZL > CK. However, the effectiveness of these amendments in decreasing the total cumulative NH4+ leaching is in the order of SZL > SWCB > SBC > CK. The rate constant (k) of DOC leaching decreased significantly with the application of bone char compared to soil alone treatment. In the presence of vinasse, the apparent half-life of leached DOC from the soil was 8.1, 12.9, 36.7, and 15.5 days for soil CK, SZL, SBC, and SWCB treatments, respectively. Half-life values of leached soluble ammonium from the soil in the presence of vinasse addition were 10.1, 39.5, 28.5, and 37.9 days for CK, SZL, SBC, and SWCB treatments, respectively. Amending soil with BC increased significantly the phosphorus availability, however, applying ZL and BC caused a significant increase in the available potassium in calcareous sandy soil compared to the control treatment. According to these results, it is recommended not to add vinasse alone to sandy soils, but it is preferred to be co-applied with BC amendment at the level of 4% better than ZL and WCB. This would decrease leaching DOC and ammonium to the water table and groundwater as well as enhance nutrient retention in the soil, which in turn, plays a vital role in reducing the harmful effect of vinasse and improving soil fertility.
