“…The high concentration of P in the biomass used in this research (7.78%) and the increase in soil pH promoted by this residue, mainly at the top, positively influenced the increase of soil P corroborating Martinez et al (2017). According to these authors, after eight consecutive desorption, the biochar of Eucalyptus globulus increased the release of phosphorus in comparison with the natural soil, between 78 and 84%, thus promoting a greater availability of this element over the time necessary for the correct nutrition of the plants.…”

Biochar is material produced during a process called pyrolysis. This material can be used as fertilizer to increase the agronomic productivity of low fertility soils. The objective of this study was to evaluate the soil chemical amendments and the macronutrients leaching following biochar application, produced from poultry litter, in Yellow Red Latosol in laboratory experiments. Soil columns (height 20 cm) containing 0; 10; 15; 20; 25 and 30 t ha-1 of biochar with four replications totaled 24 experimental units. For 30 days, water was applied daily to each column, and the leachates were collected and chemically characterized. After this period, soil samples were taken from the 0-10 and 10-20 cm layer depth and chemically characterized. Biochar reduced exchangeable acidity values. Biochar improved soil fertility. Leachates contained increasing EC, K, Na, Ca and Mg, however the concentration of these elements were small in relation to the biochar doses.

“…In our study, this relationship was noted for BC-2 and BC-3 biochars used at 1 and 2 % doses. The obtained results and the results presented by other authors show that there is a large discrepancy regarding the biochar's effect on the available P content in soil [39][40][41].…”

“…According to Murphy and Stevens [36] and Mukherjee et al [37], the increase in the pH value for acidic soils translates into an increase in the number of negative charges of soil colloids, leading to an increase in anionic repulsion and reduction of sorption of phosphate anions. As stated by Hong and Lu [38] and Martinez et al [39], the addition of biochar to the soil favours P desorption, which leads to the element increase in soil solution. In our study, this relationship was noted for BC-2 and BC-3 biochars used at 1 and 2 % doses.…”

In the course of analysing sewage sludge biochar (BC) as a material containing phosphorus loads, we determined the following: effect of thermal conversion of three different sewage sludge biochars on the content and availability of P in biochars (BC-1, BC-2 BC-3), effect of their application on selected forms of P in soil and on the accumulation of this component in Poa pratensis L. biomass. Regardless of the type of BC, the contents of P-H2O and P-CaCl2 were lower than the contents determined in unconverted sewage sludge. A significant increase in the content of P-CaCl2 compared to the control was noted in the soil of treatments where 1 and 2 % additions of BC-2 and BC-3 were applied. Soil pH (r = 0.826; p ≤ 0.05) and the content of Ca-exchangeable (r = 0.712; p ≤ 0.05) had the strongest effect on the content of P-CaCl2 in soil; however, no significant relationship was found between the amount of P-introduced with BC, the contents of Al-ox., Fe-ox. and the content of P-CaCl2. Significant (p ≤ 0.05) increase in the phosphorus content in plant biomass was noted in all treatments compared to the control. Regardless of the type of biochar applied, the highest amount of P-uptake was determined in treatments where the greatest addition of BC (2 %) was introduced into the soil. A significant relationship between P-uptake and the amount of P-introduced with BC into the soil (r = 0.726; p ≤ 0.05) was demonstrated.

“…In general, it was observed that soil–biochar with CP biochar had a lesser P sorption maximum as compared with those incubated with CH biochar for 7 days of incubation, whereas, at 60 days of incubation the adsorption maximum were more or less the same. Other studies, however, showed reduction in phosphate sorption in acidic soils as a result of biochar application because of precipitation of Al 3+ and Fe 3+ (sites for phosphate complexation) (DeLuca et al, 2015) and increase in repulsion by the negative charges newly created in the soil, by ‐O − and –COO − from biochar (Martínez et al, 2017). This can be confirmed with the rise in soil organic carbon content (Table 2).…”

“…Moreover, biochar added to acid soils have contrasting results on the fixation of P through sorption studies. Some results have presented an increase in sorption of P over the control acid soils because of the binding of phosphate to the carbonates and oxides of Ca and Mg (Novak et al, 2009; Xu et al, 2014; Zhang et al, 2016) while on the contrary, less sorption of P was also observed than the control acid soils which was attributed to the precipitation of Al 3+ and Fe 3+ (DeLuca et al, 2015) and the repulsion of the negative phosphate ions by the negative charge of biochar (Chintala, Schumacher, et al, 2014; Martínez et al, 2017).…”

Acid soil in West Cameroon has limited phosphorus (P) availability which limits plant growth. This is mainly because of low pH, high levels of exchangeable aluminium (Al) and iron (Fe) and fixation of P. In this study, acid soils, sampled in Bafang, were amended with biochar produced from coffee husks (CH) and cocoa pod husks (CP) at two different temperatures (350 and 550 °C) in other to evaluate the effect on the physicochemical properties of the acid soil and the effect on P sorption and desorption. The soil was amended with biochar at a rate of 0, 20, 40 and 80 g/kg and incubated for 7 and 60 days. Physicochemical properties of all soil–biochar samples were determined followed by sorption experiments and data fitted in the Langmuir and Freundlich isotherm models in other to evaluate soil P sorption capacity and its affinity to soil amended with biochar. Moreover, desorption studies were done to evaluate the availability of P in soil amended with biochar after sorption. The outcomes of this study reveal an increase in soil pH, electrical conductivity (EC), available P, soil organic carbon and a drastic decrease in exchangeable Al and Fe. The point of zero charge of biochar‐amended soil was higher than the control and increased with amendment rate. The experimental data of the sorption of P on soils and soil–biochar samples fits into Langmuir and Freundlich models (R2 > 0.9) suggesting that the P adsorption is controlled by both model mechanisms. Soil–biochar mixture results in a decrease in the sorption capacity as compared with the control and the decrease was predominant with increasing amendment rate. At amendment rates of 20, 40 and 80 g/kg after 7 days of incubation, Qmax for SCH350 were 2267, 2048 and 1823 mg/kg which increased to 2407, 2112 and 1990 mg/kg after 60 days of incubation. This tendency was observed for all biochar inputs with respect to the increase in incubation days. Furthermore, desorption of P from soil–biochar mixtures was enhanced with biochar added at greater rate and produced at higher temperature. The desorption percentage was increased by more than around 10% for all biochar types from 20 mg/kg to 80 mg/kg amendment. Thus, biochar addition to acid soils reduces P fixation to acid soil and improves P desorption to soil solution, thereby providing more available P in the soil solution and better conditions for plant growth.
