“…4). Biochar acts as a source of soluble P, thus potentially increasing the amount of water-soluble P in soil solutions (Parvage et al 2013;Matin et al 2020). Furthermore, it can release organic acids, which affect P availability by forming organometal complexes with calcium minerals, releasing P from apatite, and decreasing P sorption (Hosseinpur et al 2012;Schneider and Haderlein 2016;Gerdelidani and Hosseini 2018).…”

“…They reported that all P fractions in the soil treated with biochar combined with fertilizer increased when compared with soils treated with biochar or P fertilizer alone. Matin et al (2020) investigated the effects of almond and walnut shell biochars (0, 2.5, 5, and 10% w/w) on P fractionation and Olsen P levels in two calcareous soils that were incubated for 30 days. They reported that adding biochar to these soils increased the lability associated with Fe and Al and the residual fractions.…”

Biochar has the potential to affect the cycle of phosphorus (P), but the underlying mechanisms of its effects remain poorly understood in calcareous soils. Our understanding of the effects of biochar is limited in calcareous soils during incubation. Therefore, this study was conducted to investigate how the availability and mineral fractions of P change after the addition of combined biochar and P fertilizer during incubation in calcareous soil. Sugarcane residue (raw SR) and biochar (400 °C for 2 h) were added to soils treated with 50 mg kg −1 of P, in the form of Ca(H 2 PO 4) 2 •H 2 O, at 0.5 and 1% (w/w). The soils were incubated at 25 ± 1 °C for 120 days. Available P (Olsen P) contents and mineral P fractions were measured after various incubation times (7, 30, 90, and 120 days). Biochar addition remarkably increased the amount of available P when compared with the raw SR treatment and the control condition (P < 0.05). After 30 days of incubation, the amount of available P in the soils decreased and remained unchanged thereafter. The results indicated that the addition of 50 mg kg −1 of P as fertilizer significantly augmented the labile P and P associated with Fe and Al in all the treatments at all incubation times (P < 0.05). In comparison with P treated with raw SR, P associated with Fe and Al was significantly enhanced after biochar addition (P < 0.05). Significant correlations were found for available P with labile P and P associated with Fe and Al. We found that biochar addition could increase available pools, thus improving available P concentrations at various incubation times. Therefore, we conclude that sugarcane residue biochar can enhance the available P in calcareous soils.

“…In addition, the difficulty of accessing sorption sites also occurs on the surface of Fe oxyhydroxides by means of humic and fulvic acids, which have the ability to temporarily inhibit P sorption, maintaining its availability for a longer time (Fink et al, 2016;Yang et al, 2019). Delayed P sorption was also observed by Matin et al (2020) when studying different ratios and types of biochar, resulting in an increase in P availability and a reduction in the need for fertilization.…”

“…In this context, Nobile et al (2020) reported that in areas managed with organic composts, P availability depended primarily on changes in pH and the P contents that these materials added to the soil. The benefits of soil conditioning with biochar were evaluated by Matin et al (2020), who concluded that the use of biochar may increase P availability even after a short application time, reducing the need for fertilization. Therefore, in Fe mining areas, revegetation may benefit from applying these materials to increase the efficiency of phosphate fertilization.…”

Phosphorus (P) fixation in the soil reduces the utilization of this element by plants and can be one of the main problems for fertilization management in soils containing Fe oxides. As a strategy to minimize the effects of P retention, organic materials, such as biochar or commercial composts, may be useful tools to maintain P availability and delay immobilization of this element in the soil, thereby benefiting, for example, the rehabilitation of areas impacted by Fe mining. The objective of this study was to evaluate the kinetics of P sorption and desorption and the hysteresis index in red mining waste from Fe mining subjected to açaí biochar and commercial compost amendments. Therefore, a substrate collected from Fe mining waste piles in the Carajás Mineral Province was incubated for 30 days with açaí biochar, commercial compost, and açaí biochar + commercial compost at a ratio of 90 % mining waste and 10 % organic amendment (w/w). The P sorption and desorption kinetics were evaluated in a solution containing 10 mg L -1 P at times from 0.5 to 48 h; the data were modeled according to a pseudo-first-order equation considering two types of reaction sites, and the hysteresis index was obtained by the difference between the sorption and desorption isotherms. Treatment of the mining substrate with açaí biochar reduced P sorption, while P desorption was increased by up to 60 % by applying biochar and/or commercial compost. Açaí biochar also reduced the hysteresis of P sorption from 78 to 54.8 %, in addition to slowing P fixation in this substrate. Thus, this study showed that açaí biochar and commercial compost may maximize the benefits of phosphate fertilization during the rehabilitation of areas impacted by Fe mining. However, as these composts can cause different effects on P dynamics in mining waste, their effects on other elements, such as micronutrients, whose availability may be affected, are important to be evaluated.

Most of them simulate the sorption of nutrients such as P [35,36] and other contaminants such as heavy metals [37]. The proposed models are fitted to experimental data to estimate the fate of elements in the solution under variably saturated media.…”

This work examines in silico the dominant geochemical processes that control inorganic nutrients (Ca, Mg, Na, K) availability in irrigated agricultural soil amended with potassium-enriched biochar (from olive mill wastes) at mass doses of 0.5%, 1%, 2% and 10%. The geochemical modelling step was supported by analytical measurements regarding the physicochemical characteristics of the irrigation water, the agricultural soil and the biochar. Two geochemical approaches, namely equilibrium exchange (E.E.) and kinetic exchange (K.E.) models were applied and compared to assess nutrient release with an emphasis on potassium availability. Equilibrium exchange perspective assumed that nutrient release is controlled by ion-exchange reactions onto the biochar surface, whilst kinetic exchange perspective assumed the contribution of both ion-exchange and dissolution of salts. Results indicated that for the E.E. model, the soluble amount of potassium is readily available for transport within the pores of the porous media, and therefore is leached from the column within only 10 days. For the K.E. model that assumes a kinetically controlled release of potassium due to interactions occurring at the solid-solution interface, the assessed retention times were more realistic and significantly higher (up to 100 days). Concerning the applied doses of biochar, for a 2% biochar fraction mixed with soil, for example, the available K for plants doubled compared with the available K in the soil without biochar. In any case, the use of numerical modeling was proven helpful for a quick assessment of biochar performance in soil, by avoiding time-consuming and laborious experimental set-ups. Validation of the models by experimental data will further establish the proposed mechanisms.
