“…In turn, the research of Gonzaga et al [18] revealed significant changes in N and P bioavailabilities due to biochar presence in sewage sludge which raised concerns about the management and effectiveness of biochar coming from sewage sludge as a soil amendment. The mentioned study showed that biochar improved plant growth during the first 60 days of cultivation and the concentration of N in plants was increased by 17-40% [18]. In addition, the research conducted by Dubis et al show great potential in sewage sludgebased fertilizers as in result their research proved that sewage sludge and mineral fertilizers exerted similar yield-forming effects for miscanthus growth [19].…”

Municipal sewage sludge is a problematic waste that needs to be managed. Modern wastewater treatment plants (WWTPs) generate stabilized sewage sludge with good chemical and biological parameters. The Central Mining Institute (CMI, Poland) has developed a proprietary technology (patent PL233754) for production of a granulated organo-mineral fertilizer from the stabilized sewage sludge. It is a mixture of municipal WWTP-collected, dewatered sewage sludge, dolomite, lime, gypsum, ammonium carbonate, and microcrystalline cellulose. The sewage sludge contained heavy metals at levels lower than: Cr, 100 mg; Cd, 5 mg; Ni, 60 mg; Pb, 140 mg; Hg, 2 mg, and was free from live eggs of intestinal parasites of the genera Ascaria, Trichuris, and Toxacara as well as from Salmonella bacteria. Micro-field tests were conducted at WWTP in Żory (Poland) on five 5 m2 fields. The effectiveness of plant growth was evaluated based on drone photos showing field coverage upon vegetation, and post-harvest determination of the plant dry mass. The analyses showed significant changes in biomass chemical composition: the N concentration was 289.6% of the control and 98.2% of commercial fertilizer, whereas the respective P content was 145.1% and 300%. The results prove that the innovative fertilizer is highly competitive with other available commercial products.

“…Xu et al (2016) found that application of 2%, 4%, and 8% corn stover biochar reduced total leached N accumulation by 18.8%, 19.5%, and 20.2%. Gonzaga et al (2022) observed that the addition of sludge biochar increased the availability P concentration from 60.20 to 124.36 mg kg −1 in bulk soils and from 192.9 to 245.9 mg kg −1 in the rhizosphere. Biochar improves soil nitrogen fixation and reduces soil nitrogen fixation losses through mechanisms such as biotic (increases in microbial biomass and activity) and abiotic (adsorption of NO 3 − , NH 4 + and organic nitrogen by biochar) nitrogen fixation, enhanced nitrogenation, reduced leaching, and denitrification (Asadyar et al, 2021).…”

Mining activities has generated large amounts of mine tailings each year, and these tailings usually contain high concentrations of heavy metal pollutants, which not only cause serious damage to the local and surrounding soil ecosystems, but also harm human health via the transmission of food chain. Phytoremediation is treated as environmentally friendly, long-term effective and low-cost restoration method. However, tailing soil acidification, low organic matter content, poor water holding capacity and compaction make plant struggle to survive. Biochar, a soil conditioner can promote plant growth by improving the physical, chemical and biological properties of soil, thus strengthening the ability of phytoremediation in the contaminated tailings. This review elaborates how the physicochemical properties of biochar affect phytoremediation; and summarized how the raw materials of biochar affect the physicochemical characteristics. Finally, the future research directions are prospected.

“…The organic acids released from biochar compete with phosphate ions and increase the soil P availability (Schneider and Haderlein, 2016). For maize, sewage sludge biochar at 30tha -1 enhanced root growth which inturn increased rhizodeposition and microbial activity and ultimately P availability in acidic Ultisols (Gonzaga et al, 2022). Borno et al (2018) reported higher P fixation in alkaline soils amended with biochar.…”

A review on biochar’s effect on soil properties and crop growth

et al. 2023

Intensive cultivation of agricultural soils causes soil degradation which emphasizes the need for sustainable soil management. Biochar, a pyrolysed carbon rich material has gained great interests among the researchers because of its eco-friendly benefits in addition to soil quality enhancement. Reviews on biochar, mainly confined to its environmental benefits like carbon sequestration and climate change. In this review, we summarize i) the effect of biochar application on soil properties (physical, chemical, biological), ii) remediation potential of biochar in heavy metal contaminated soils and iii) its impact on crop productivity. The properties of biochar like pH, greater surface area, cation exchange capacity, and nutrient content positively influences the soil properties and ultimately improves the soil fertility. Their effectiveness depends on biochar type, its dosage, soil type, etc. General trends from this review indicated that biochar as an effective amendment in acid soils than the alkaline or calcareous soils. Furthermore, the biochar effects are studied mostly under controlled conditions in laboratory, which needs to be validated under field conditions having varied soil types and agro-climatic zones.
