“…The increase in P availability and the decrease in P adsorption capacity as a function of biochar application were also observed by Soinne et al [46] and Han et al [47], who attributed this finding to the increase in soil pH promoted by the use of this material. The pH elevation increases the formation of negative charges on the surface of soil particles, increasing repulsive forces and reducing P adsorption, in addition to reducing the formation of H 2 PO 4 − , a chemical species that preferentially adsorbs onto soil colloids [45,48].…”

Organic materials, such as biochar and organic compost, can reduce P sorption mechanisms and improve soil fertility, benefiting the reclamation of areas impacted by mining. This study evaluated how the chemical properties of Fe mining soil, the adsorption of P onto this substrate, and the growth of the native plant Dioclea apurensis, were affected by the application of açaí biochar (BC), organic compost (OC), and different P doses. Substrate collected from mining soil piles was incubated for 30 days with BC or OC. Each mining substrate with or without the addition of BC or OC received five doses of P (0, 40, 80, 120, and 240 mg∙kg−1 P). The addition of BC or OC promoted an increase in pH and nutrient availability (P, K, Ca, and B) in Fe mining soil. However, plants grown in the unamended mining soil (W) showed higher growth. The maximum P adsorption capacity decreased as a function of the addition of BC. We conclude that the application of BC reduced P sorption, while the application of either OC or BC altered the chemical properties of the soil and caused contrasting effects on P dynamics in Fe mining soil, and these treatments also affected plant growth.

“…Besides its considerable role in refilling the carbon sink and improving soil physical properties (Lehmann & Joseph, 2009;Lehmann et al, 2011), biochar has been promoted as a means of increasing plant-available P (Glaser & Lehr, 2019;Melaku et al, 2020). Biochar improves plant-available P through several mechanisms, such as (i) P released from the biochar itself (Glaesner et al, 2019;Zwetsloot et al, 2016), (ii) the effect of biochar on soil pH (Glaser & Lehr, 2019), (iii) interaction between the biochar surface and cations (i.e., Fe/Al) (Han et al, 2018) and (iv) the effect of biochar on anion exchange capacity (Lawrinenko et al, 2016). Biochar application also increases soil microbial activity and alters the community structure, both of which are responsible for P cycling (Hardy et al, 2019).…”

Although the addition of biochar has been shown to reduce the phosphorus (P) adsorption capacity of soil, quantitative evidence of this has mainly been provided by incubation experiments and it is therefore essential to conduct longterm field trials to draw general conclusions. It is largely unknown whether bone char has a greater effect than lignocellulosic biochar on P adsorption-desorption processes and crop yield. The aim of this study was to determine the long-term (8 years) effect of bone char and biochar on P adsorption-desorption and crop yield in low-input acidic soils. The results showed that bone char decreased the maximum P adsorption capacity (Q m ) by 10% and increased the desorption capacity (D s ) by 150% compared with the control (i.e. without a soil amendment). The desorption ratio was highest for the bone char treatment (10.3%) and three times more than the control. Plant-available P was seven times greater under bone char than the control. There was no variation in adsorption-desorption characteristics, desorption ratio and plant-P available content between bone char and lignocellulosic biochar treatments. The average yield increment following the application of bone char and biochar was 1.7 and 1.4 Mg ha −1 for maize and 1.8 and 1.9 Mg ha −1 for soya bean, respectively. Despite the low application rate (4 t ha −1 year −1 ), these findings demonstrated that the long-term application of bone char and biochar-based amendments enhanced P availability in low-input cropping systems, mainly by altering the P adsorption and desorption capacity of soils.

“…In a similar study, Mensah and Frimpong [27] found that application of biochar with compost increased the soil pH. The increase in the pH could be attributed to the increase in available soil P due the presence of P in biochar [43] [44].…”

Ghana's soil is continuously declining in fertility due to continuous cultivation and rapid mineralization of its soil organic matter. Previous studies have touted the potential of biochar to help improve soil properties and increase the yield of crops. This study investigated the effects of the application of biochar on physicochemical properties of soil and the yield of maize and cabbage in Ghana. The study indicated that application of biochar significantly increased soil organic matter (SOM) from 3.88% (for control) to 5.72% (for biochar application rate 20 ton/ha and 0 ton/ha of NPK). It also increased soil pH from 6.55 in (for control) to 7.30 (for biochar application rate 20 ton/ha) and 0 ton/ha of nitrogen (N), phosphorus (P) and potassium (K) which can help ameliorate the soil acidity problem of Ghanaian soils. This field study, demonstrated that addition of biochar from sawdust increased the yield (between the control (0 ton/ha of biochar, 0% of recommended dose of NPK) and 20 ton/ha, 0% recommended dose of NPK) of maize and cabbage by 6.66% and 7.57% respectively. This study concluded that application of biochar offers a great potential to improve soil quality and the yield of maize and cabbage in Ghana.
