“…The effects of OM on the adsorption process of chloride and sulfate are still controversial. Some earlier studies reported the blockage of adsorption sites on the soil by OM (Breus, Mishchenko, Shinkarev, Neklyudov, & Breus, ). Whereas, some of the researchers considered that it was the negative charge of organic matter that reduced the soil's sulfate and chloride sorption capacity (Caporale & Violante, ; Violante, Cozzolino, Perelomov, Caporale, & Pigna, ).…”

The present study investigated the fate and transport of two significant anions through soil to explore their potential as groundwater contaminants. The retention properties of chloride and sulfate in soils having several significantly different characteristics (soil-1 and soil-2) were determined using adsorption test and adsorption-diffusion column experiments. The maximum adsorption capacity of chloride was 3.7 and 1.16 mg/g, respectively, in soil-1 and soil-2, with organic matter (OM) content of 3.92% and 4.69%, respectively. The sulfate adsorption obtained was 24.09% and 13.83%, respectively, in the two soils. The anions exhibited monolayer adsorption in the soils with replacement of hydroxyl ions from soils as the major mechanism of adsorption. On the other hand, the adsorption capacities obtained from the adsorption-diffusion column experiment were about 100 times lower compared to that of the column tests of both of the soils. The maximum adsorption capacity of chloride was 0.03 mg/g and 0.01 mg/g, respectively, in soil-1 and soil-2, whereas that of sulfate was 0.04 mg/g and 0.03 mg/g. The empirical relation for depth of penetration (d) from a known spillage onto the soil surface was determined as a function of sorption capacity (S) and initial anion concentration (C) as d = 0.0073e (−57S) C and d = 0.0038e (−35S) C for chloride and sulfate, respectively.

“…Specifically, these soils feature high water infiltration rate, low water holding capacity, large evaporation, and low fertility and organic matter content, leading to low water supply and utilization efficiency (Alaa et al, 2017). Generally, low soil organic matter content results in poor water holding capacity and weak soil structure (Breus et al, 2014). Studies have shown that the physical and chemical properties of soils can be improved by adding organic and inorganic amendments, such as biochar (Tang et al, 2015;Basanta et al, 2017;Zhou et al, 2020).…”

Aeolian sandy soil in mining areas exhibits intense evaporation and poor water retention capacity. This study was designed to find a suitable biochar application method to improve soil water infiltration and minimize soil water evaporation for aeolian sand soil. Using the indoor soil column method, we studied the effects of three application patterns (A (0-20 cm was a mixed sample of mixed-based biochar and soil), B (0-10 cm was a mixed sample of mixed-based biochar and soil and 10-20 cm was soil), and C (0-10 cm was soil and 10-20 cm was a mixed sample of mixed-based biochar and soil)), four application amounts (0% (control, CK), 1%, 2%, and 4% of mixed-based biochar in dry soil), and two particle sizes (0.05-0.25 mm (S1) and <0.05 mm (S2)) of mixed-based biochar on water infiltration and evaporation of aeolian sandy soil. We separately used five infiltration models (the Philip, Kostiakov, Horton, USDA-NRCS (United States Department of Agriculture-Natural Resources Conservation Service), and Kostiakov-Lewis models) to fit cumulative infiltration and time. Compared with CK, the application of mixed-based biochar significantly reduced cumulative soil water infiltration. Under application patterns A, B, and C, the higher the application amount and the finer the particle size were, the lower the migration speed of the wetting front. With the same application amount, cumulative soil water infiltration under application pattern A was the lowest. Taking infiltration for 10 min as an example, the reductions of cumulative soil water infiltration under the treatments of A2% (S2) , A4% (S1) , A4% (S2) , A1% (S1) , C2% (S1) , and B1% (S1) were higher than 30%, which met the requirements of loess soil hydraulic parameters suitable for plant growth. The five infiltration models well fitted the effects of the treatments of application pattern C and S1 particle size (R 2 >0.980), but the R 2 values of the Horton model exceeded 0.990 for all treatments (except for the treatment B2% (S2) ). Compared with CK, all other treatments reduced cumulative soil water infiltration, except for B4% (S2) . With the same application amount, cumulative soil water evaporation difference between application patterns A and B was small. Treatments of application pattern C and S1 particle size caused a larger reduction in cumulative soil water evaporation. The reductions in cumulative soil water evaporation under the treatments of C4% (S1) , C4% (S2) , C2% (S1) , and C2% (S2) were over 15.00%. Therefore, applying 2% of mixed-based biochar with S1 particle size to the underlying layer (10-20 cm) could improve soil water infiltration while minimizing soil water evaporation. Moreover, application pattern was the main factor affecting soil water infiltration and evaporation. Further, there were interactions among the three influencing factors in the infiltration process (application amount×particle size with the most important interaction), while there were no interactions among them in the evaporation process. The results of this study could contribute...
