“…), the pyrolysis process (e.g., fast, slow, and gasification), and the temperature during pyrolysis [3,14]. BCs derived from woody feedstock demonstrate particularly important ameliorative properties that include high ability to sorb soil contaminants [15], retain nutrients and water [16][17][18], increase soil pH, and provide pulses of nutrients that are potentially limiting in certain systems (e.g., phosphorus in Pluchon et al [19]). …”

“…Synergistic effects of a BC-compost blend on plant growth and performance are thought to be mediated by sorption of nutrients by the porous BC matrix [29], stimulation of microbial colonization [32], degradation of possible noxious pyrogenic substances [33], improvement of the BC surface reactivity through accelerated oxidative ageing [34,35] and dissolved organic carbon sorption [36]. The hypothesized synergy is likely to be particularly effective in offsetting potentially toxic effects of high metal and salt concentrations in SMS since BCs have demonstrated the ability to mitigate salt stress [15] and metal bioavailability [1]. Indeed, recent work by Beesley et al [37] shows promise for BC-compost applications to soils contaminated by metals and arsenic.…”

Abstract:The combination of biochar (BC) with compost has been suggested to be a promising strategy to promote plant growth and performance, but although "synergistic" effects have been stated to occur, full-factorial experiments are few, and explicit tests for synergism are lacking. We tested the hypothesis that a combination of BC and spent mushroom substrate (SMS) has a positive synergistic effect on plant growth and physiological performance in a nutrient-limited growing media. A greenhouse experiment with a full factorial design was conducted using mixed-wood BC (3.0 kg·m −2 ) and SMS (1.5 kg·m −2 ) (the combination was not co-composted) as organic soil amendments for the annual Abutilon theophrasti and the perennial Salix purpurea. Several measurements related to plant growth and physiological performance were taken throughout the experiment. Contrary to the hypothesis, we found that the combination of BC + SMS had neutral or antagonistic interactive effects on many plant growth traits. Antagonistic effects were found on maximum leaf area, above-and belowground biomass, reproductive allocation, maximum plant height, chlorophyll fluorescence, and stomatal conductance of A. theophrasti. The effect on S. purpurea was mostly neutral. We conclude that the generalization that BC and compost have synergistic effects on plant performance is not supported.

“…Several studies have focused on the beneficial effects of biochar fertilization on the chemical, physical and biological properties of the soil, as well as on increasing biomass accumulation and crop productivity (Kookana et al, 2011;Thomas et al, 2013;Jien & Wang, 2013). Utomo et al (2012) verified that the application of 15 t ha -1 of biochar reduced the need for application of nitrogen fertilizer by up to 43% to produce the same amount of maize dry matter; however, according to Steiner et al (2007) greater efficiency when it is associated with mineral fertilization due to its low availability of nutrients.…”

The use of alternative sources such as biochar can contribute to sustainable agriculture. The objective of this study was to evaluate the effect of fertilization with biochar in combination with mineral fertilizer, growth rates and yield of sunflower cv. Embrapa 122/V2000. The experiment was carried out in a protected environment of UAEAg/CTRN/UFCG in pots with a capacity of 20 dm 3 under a completely randomized experimental design, with treatments arranged in a factorial scheme (5 × 4) and four replicates corresponding to five doses of mineral fertilization 0, 25%, 50%, 75%, and 100% of fertilization indication with NPK (100, 300, and 150 mg kg ) and four doses of biochar, 0; 5% (400 g/pot); 10% (800 g/pot) and 15% (1100 g/pot) calculated on the basis of the soil volume. Fertilization with biochar promoted an increase in sunflower growth rates in the evaluation periods. The combination of 50: 150: 75 mg kg -1 of NPK and 400 g/pot of biochar promotes higher production of sunflower (23.91 g/plant).

“…The biochar remediation of Cu, Zn, and Cd in soil samples has also been evaluated [27]. The capacity of activated charcoal to absorb a variety of salts has long been noted [28], and charcoal has also been utilized in industrial desalination processes [29,30]. However, the potential use of biochar as a soil amendment to mitigate salt-induced plant stress appears to have received essentially no prior research attention.…”

Characterization and Potential Use of Biochar for the Remediation of Coal Mine Waste Containing Efflorescent Salts

Abstract:In open pit coal mining, soil and vegetation are removed prior to the start of mining activities, causing physical, chemical, and microbiological changes to the soil and landscape. The present work shows the results of an integrated study of the remediation of mine waste with a high level of salt contamination in areas of the Cesar Department (Colombia), employing biochar as an amendment. Physical-chemical properties including Munsell color, texture, pH, electrical conductivity, water-holding capacity, cation exchange capacity, metal content, organic carbon, sulfates, extractable P, and total nitrogen were characterized both in the soils contaminated with mine residues and the biochar sample. A high concentration of sulfates, calcium, iron, and aluminum and a significant presence of Na, followed by minor amounts of Mg, K, Cu, and Mn, were observed in efflorescent salts. X-ray diffraction indicated a high presence of quartz and gypsum and the absence of pyrite and Schwertmannite in the efflorescent salt, while showing broad peaks belonging to graphene sheets in the biochar sample. Soil remediation was evaluated in Petri dish seed germination bioassays using Brachiaria decumbens. Biochar was shown to be effective in the improvement of pH, and positively influenced the germination percentage and root length of Brachiaria grass seeds.
