“…Taken together, these findings suggest that biochar amendments in coarse-textured soils increase water retention by reducing soil evaporation loss, while allowing for more drainage for a rainfed pasture system. Similar findings have been observed in other studies (Abel et al, 2013;Altdorff et al, 2019;Arthur et al, 2015;Günal et al, 2018;Kroeger et al, 2021;Mollinedo et al, 2015;Stylianou et al, 2021), supporting the belief that even 5% biochar augmentation can increase water retention within coarse-textured soils.…”

“…Given the complex and multiple interactions governing the impacts of biochar addition, modeling studies have been used to study the impact of biochar amendment on crop yield and overall environmental effects (Aller et al, 2018;Archontoulis et al, 2016;Horel et al, 2019;Huang et al, 2020;Jellali et al, 2016;Kameyama et al, 2012;Lefebvre et al, 2020;Lychuk et al, 2015;Major et al, 2012;Stylianou et al, 2021). For example, Lefebvre et al (2020) modified the RothC model to evaluate sugarcane biochar and its potential for carbon sequestration in Brazil.…”

For example, Wu et al (2019) stimulated 48 h of water flow in soil amended with maize biochar (450˚C) at five different rates to topsoil (25 cm) and observed higher saturated water content (θs) and lower residual water content (θr) with increasing application rates.…”

“…In this regard, HYDRUS (Arora et al., 2011; Karandish & Šimůnek, 2018; Šimůnek et al., 2016; Turkeltaub et al., 2018) has been successfully used to simulate biochar effects on soil hydraulic properties (Arabyarmohammadi et al., 2018; Filipović et al., 2020; Horel et al., 2019; Wu et al., 2019). However, the majority of these studies have focused entirely on short‐term effects (e.g., 48 h–85 days) of biochar application (Altdorff et al., 2019; Filipović et al., 2020; Horel et al., 2019; Stylianou et al., 2021; Wu et al., 2019).

Application of biochar amendments in agricultural systems has received much attention in recent years. In this study, we assess the 5‐year impacts of biochar application on soil water and plant interactions for an irrigated fresh market tomato (Solanum lycopersicum) and a rainfed pasture (Poaceae) cropping system. In particular, we focus on three varieties of locally produced biochar from agricultural waste materials—almond shell, walnut shell, and almond pruning residues that are pyrolyzed using a mobile pyrolysis unit. We used the soil hydrological model HYDRUS‐1D to explicitly track seasonal and annual soil water fluxes through changes in water retention, drainage, evaporation, and plant water uptake under biochar application. Modeling results show that the application of biochar at 5% increased soil water availability within the top 20 cm for a rainfed system, irrespective of biochar amendment type. This is clearly indicative of higher plant water uptake and greater water use efficiency (WUE) under biochar application. In contrast, a similar biochar amendment for the irrigated system did not affect WUE, instead reducing seasonal soil evaporation loss and thereby reducing irrigation demand. In both cropping systems, year‐to‐year variability in precipitation significantly impacted the total amount of water saved under biochar application with certain amendments retaining more water than others. Given that biochar application increased water retention irrespective of cropping systems, we further used a simple approach to determine yield trade‐off, if any, between control and biochar treatments. Our economic balance clearly demonstrates that the water saved by amending soil with biochar does not offset the yield disparity if compensated with carbon credits and therefore, application of biochar should be actively considered for both its direct and indirect benefits to potential greenhouse gas mitigation (e.g., diverting orchard waste from open burning), water savings, and soil health.

“…Similarly, Blanco-Canqui (2017) confirmed that biochar contributed to the reduction of saturated hydraulic conductivity in soils. By contrast, Stylianou et al (2021) came to the conclusion that applied biochars (5%) from biowaste of sludge and spent coffee grounds considerably increased saturated hydraulic conductivity of the loamy sand soil when compared to the control variant.…”

The field trial evaluating the effect of biochar on physical and hydro-physical properties of a Dystric Cambisol was carried out at the Research Grassland Station Vatín. The observed variants of the biochar experiment were as follows: 1) the control without biochar, 2) the biochar rate of 15 t/ha applied to the topsoil, 3) the biochar rate of 30 t/ha applied to the topsoil and 4) the biochar rate of 45 t/ha applied to the topsoil. It was found out that even the highest rate of biochar 45 t/ha did not affect saturated hydraulic conductivity of the topsoil at the depth of 0.05-0.20 m. When monitoring bulk density, it was confirmed that the biochar rate of 45 t/ha significantly reduced bulk density from 1218 kg/m 3 to 1169 kg/m 3 . In the crop rotation without manure and clover growing the application of biochar at the rate of 45 t/ha resulted in the relevant decline in the average value of bulk density from 1197 kg/m 3 to 1138 kg/m 3 . In the Norfolk crop rotation there were the inconclusive differences in bulk density. The rate of 45 t/ha had a highly noticeable impact on porosity. It increased from 53.75% (0 t/ha) to 55.60%. The biochar doses did not affect the value of field capacity. The application of biochar at the rate of 45 t/ha caused the significant increase in the average value of aeration from 31.90% to 34.45%.
