“…Contamination of soils with heavy metals (HMs) has been considered one of the most serious worldwide problems that threatens the ecosystem and human life [1][2][3]. The Industrial Revolution, extensive mining, smelting, effluents discharge, and intensive agricultural fertilization threaten soil quality, food safety, and human health [4,5]. In China, Shaoguan city, located in northern Guangdong Province, contained acid soils contaminated with HMs due to the discharge of industrial effluents for more than 50 years and mining activities [6].…”

“…Incorporation of biochars into soils often leads to a decrease in their bulk density (Abd El-Mageed et al, 2021;Hardie et al, 2014). A degree of biochar-induced decrease in soil bulk density depends on soil texture and biochar application dose (Murtaza et al, 2021). In the conducted experiment the biochars application affected the bulk density of the coarse-textured soil more than that of heavy-textured soil.…”

“…Biochars produced under different conditions can have different physical (bulk density, porosity), physico-chemical (pH, CEC, BET surface area, oxygenated functional groups) and chemical (total carbon, nitrogen, hydrogen content) properties which, in due course, can have positive, neutral or negative effect on soil properties (Das et al, 2021;Liao et al, 2021;Novak et al, 2009;Rajapaksha et al, 2014) and crop yields (Murtaza et al, 2021). According to Bruun et al (2012), application of fast pyrolysis biochar (produced from wheat straw) resulted in immobilization of soil N (43%) during the 65-day incubation, while application of slow pyrolysis biochar led to net N mineralization (7%) in soil.…”

“…Moreover, BC improves soil porosity, moisture retention capacity, and water use efficiency to reduce drought effects on crop yield (Abideen, Koyro, Huchzermeyer, Ansari, et al., 2020; Hafeez et al., 2017; Hansen et al., 2016). Since BC has high organic carbon contents, it can act as a soil conditioner to improve the physicochemical and biological properties of soil (Murtaza et al., 2021). Increased plant growth such as in tomato (Akhtar et al., 2014; Mulcahy et al., 2013) and barley (Hansen et al., 2016) has been observed under drought stress via BC application.…”

“…Poultry manure‐derived BC serves as a natural organic fertilizer due to the large amount of NPK, and other micronutrients. Under drought stress, it improves the WHC of the soil due to its positive effect on soil physicochemical and biological properties (Bashan et al., 2012; Murtaza et al, 2021). Similarly, BC application to sandy soil is beneficial to both crop growth and dramatically improves the P availability of the coarse soil (Bashir et al., 2020; Foster et al., 2016).…”
