“…As shown in Figure 1A, pH practically did not vary in the soil without biochar, however, the biochar applied to the soil increased soil pH in the two layers analyzed (top and base), corroborating Yuan and Xu (2012), and Silva et al (2017) who observed an increase in pH of the soil, considering the positive effect of biochar, particularly in acid soils. However, more significant changes were observed at the top whose calculated maximum pH value reached 8.22 applying 29.28 t ha -1 ( Figure 1A).…”

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.

“…On the other hand, the great quantity of K obtained because of OMSW-derived BC could result in reduced plant uptake of Ca, Mg, and P by an antagonistic effect [47, 48]. Contrary to our results, several reports found increases in the plant content of nutrients [44, 49]. The discrepancy between our data and that of other studies could be explained because of varying soil characteristics and feedstock used to produce BCs.…”

“…The high content of soil exchangeable basic cations in the high pyrolysis-temperature BC-treated soil could be explained by the increasing content of BC ash. Several other researchers have explained the improvements in the exchangeability of soil cations because of the presence of ashes in BC, which contain high levels of oxides and hydroxides of alkali cations [44].…”

36In this study, a greenhouse pot experiment with maize (Zea mays L.) was conducted using treatments 37 consisting of a control (CK), inorganic fertilizer of NPK (INF), and 1% and 3% (wt/wt) of olive mill solid 38 waste (OMSW)-derived biochar (BC) at various pyrolytic temperatures (300-700 °C). The goal was to 39 investigate potential negative versus positive effects of BC on pH, electrical conductivity (EC), and 40 nutrient (P, K, Na, Ca, Mg, Fe, Mn, Zn, and Cu) availability in a calcareous loamy sandy soil. The results 41 showed that application of OMSW-derived BC, especially with increasing pyrolysis temperature and/or 42 application rate, significantly increased soil pH, EC, NH 4 OAc-extractable K, Na, Ca, and Mg, and 43 ammonium bicarbonate-diethylenetriaminepentaacetic acid (AB-DTPA)-extractable Fe and Zn, while 44 AB-DTPA-extractable Mn decreased. The application of 1% and 3% BC, respectively, increased the 45 NH4OAc-extractable K by 2.5 and 5.2-fold for BC300, by 3.2 and 8.0-fold for BC500, and by 3.3 and 46 8.9-fold for BC700 compared with that of untreated soil. The results also showed significant increases in 47 shoot content of K, Na, and Zn, while there were significant decreases in shoot content of P, Ca, Mg, and 48 Mn. Furthermore, no significant effects were observed for growth of maize plants as a result of biochar 49 BC addition. In conclusion, OMSW-derived BC can potentially have positive effects on the enhancement 50 of soil K availability and its plant content but it reduced shoot nutrients, specifically P, Ca, Mg, and Mn; 51 therefore, application of OMSW-derived BC to calcareous soil might be restricted. 52

“…The increase in soil pH values may be explained by the presence of ashes in the BioC. Ashes are rich in oxides and hydroxides of alkali metals, which are easily dissolved and react rapidly with the soil, thereby increasing its pH [48]. These results are consistent with Mierzwa-Hersztek et al [49], whose research showed that alkaline substances are easily released from BioC.…”

Impact of Biochar on Physicochemical Properties of Haplic Luvisol Soil under Different Land Use: A Plot Experiment

2019

There is limited information regarding the effect of biochar (BioC) on improving the fertility of degraded soils (fallow and grassland), particularly with respect to changes with time. The objective of the study was to evaluate, in a three-year field experiment, the influence of BioC on the physicochemical properties of Haplic Luvisol. BioC, obtained via wood waste pyrolysis at 650 °C, was applied to the soil of subplots under fallow and grassland at rates of 0, 1, 2, and 3 kg·m−2. Soil samples were collected eight times, from 2013 to 2015. Physicochemical characterization was performed for soil and BioC by analyzing density, pH, surface charge, as well as ash and organic carbon content. BioC’s influence on the physicochemical properties of degraded soils was determined by analyzing the changes in pH, specific surface area, radius, and volume of the micropore. The addition of BioC affected analyzed soils to varying degrees. In the case of the fallow, a positive effect on changes in these parameters was observed, particularly at the highest biochar dose and for the last year of the experiment. However, for the grassland, in most cases we observed the opposite trend—for example, pH and specific surface area values decreased with increasing biochar dose. We believe that it is necessary to examine how BioC affects sorption properties of organic matter of fallow and grassland soils, as well as the BioC’s influence on humic acids of these soils as a function on BioC dose and function of time.
