“…These relationships were statistically reinforced by PCA, which showed two very different groupings, corresponding, on the one hand, to the blockage of Pi through micronutrients bridges and, on the other hand, the potential liming action of Ca and Mg ( Figure S6). These relationships were supported by the results obtained in the greenhouse experiment with tomato ( Figure S7), which showed positive results in acidic soils, but any effect in the alkaline soils agreed with the results reported by other studies [2,8] (Figure 5). It is noteworthy that the result obtained for N foliar content in acidic soil increased with biochar treatment ( Figure 6).…”

“…The biochar use might be considered notable in comparison to the well-known humic and composted material applications as soil improvers or fertilization enhancers [6,7]. Although biochar application is widespread, some authors have shown an improvement in crop yields for acidic soils, but the opposite for alkaline soils [2,8]. One explanation of this loss of fertilization capacity of biochar in comparison to terra preta could be the lower Pi content of biochar in comparison to that of terra preta, which is assumed to originate from "Ash from fires, bones from fish and game animals, feces, urine, and turtle shells account for the relatively high levels of phosphorus in black earth" [9].…”

Because of the low consistency of the results obtained in the field, the use of biochar as a soil amendment is controversial. Thus, in general, in acidic soils, results are positive, while in alkaline soils, they are non-significant or even negative. The results regarding biochar action in acidic soils have been related to a lime-like effect due to its alkaline pH and the high doses normally used. However, the causes of biochar effects in alkaline soils remain unknown. Our objective was to explore the chemical mechanism of biochar interaction in acidic and alkaline soils. We used well-characterized biochar as a component of two complex N and PK granulated fertilizers at two different doses (1% and 5%). These fertilizers were applied to wheat cultivated in pots containing an alkaline soil and grown for 60 days. No effect was shown for the N-biochar fertilizer application. However, the PK-biochar fertilizer application caused a decrease in crop yield. In addition, the adsorption isotherms of Al, Fe, Mo, Mn, and Phosphate (Pi) in biochar were also studied. The results showed that Fe and Al were rapidly adsorbed in biochar, while Pi was only adsorbed on the Fe-, Al-biochar complex. Desorption experiments showed that P and Fe/Al were not desorbed from the P-Fe/Al-biochar complex by water or the Olsen reagent, while partial desorption was observed when HCl 0.1 M was used. This blockage of Fe/Al and P through Fe/Al bridges in biochar could partially explain the negative effects in alkaline soils. After these studies, soil solution sorption experiments were carried out in both acidic and alkaline soils and were complemented with a greenhouse trial using tomato plants. The results showed that biochar enhanced foliar Ca and N content, as well as growth in acidic soil only, and the possible mechanism of the failure in alkaline soils.

“…BC40%+Urea60%, consisting of both biochar and chemical fertilizer, had a positive effect through the synergistic effect of biochar and chemical fertilizer for nutrients (Schulz and Glaser, 2012), nitrogen availability, and the ability for water as well as nutrient availability and retention (Herlihy and Carroll, 1969;Youseef et al, 2017). The negative impact of sole biochar application on production could be attributed to the alkalinity effect of biochar, raising pH, in turn, reducing nutrient availability (Salem et al, 2019), N immobilization, and the probable presence of inherent undesirable compounds (Lehmann and Joseph, 2015;Solaiman et al, 2012;Spokas et al, 2012). Higher dry matter as produced by BC40%+Urea60% could be attributed to its role in tuber maturity, growth characters (leaves, canopy, stem), water and nutrient uptake (Gebre et al, 2020;Youseef et al, 2017).…”

Field research was carried out to examine the biochar effect on growth, tuber quality, and yield of the potato crop. Treatments were laid out in a randomized complete block design with 7 treatments of different combinations of biochar and urea (BC100%, BC80%+Urea20%, BC60%+Urea40%, BC40%+Urea60%, BC20%+Urea80%, Urea100%, BCC) as nitrogen source with 4 replications, where all treatments supply recommended dose of fertilizer except control treatment (BCC). The tested variety of potato was Janakdev. The recorded observations showed that biochar mixed with chemical fertilizer had a significantly superior effect on growth (height, branches number, canopy), marketable tuber weight and number, tuber size, yield, and dry matter % as compared to sole biochar (BC100%), sole chemical fertilizer (Urea100%), and control (BCC) treatments. Among the treatments, BC40%+Urea60% (Biochar applied @ 10 t/ha) had resulted significantly higher marketable tuber weight and number, tuber size, yield, and dry matter %. Our results thus demonstrate that the application of chemical fertilizer in combination with biochar could effectively enhance the plant growth, tuber quality, and yield of the potato crop.

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
