“…The soil available P, available K, TOC and IC contents exhibited an increasing trend as the applied biochar amount increased in this study, which was consistent with the results of other studies (Ahmed et al, 2016). The biochar application could increase the available K content for its higher potassium content and bioavailability in red soil and yellow brown soil (Syuhada et al, 2016). The total K and available K contents in this study also had the similar trend after biochar application.…”

The effect of rice straw biochar on soil nutrients was studied using a randomized block experimental design in a tobacco-planting field, and differences in soil bacterial and fungal community structures were studied using high-throughput sequencing technology. The results indicated that the soil pH, CEC, total organic carbon (TOC), inorganic carbon (IC), soil total nitrogen (total N), total potassium (total K), available phosphorus (available P), and available potassium (available K) contents were all increased with the biochar application. TOC and available P contents increased by 38.19% and 22.38%, respectively, in the T2 treatment (4500 kg . ha -1 biochar) compared to those in control (CK). But the soil dissolved organic carbon ( DOC) and available nitrogen (available N) content decreased by 13.07% and 9.89% in T2 treatments compared to the CK, respectively. Soil bacteria composition mainly consisted of Proteobacteria, Actinobacteria, and Acidobacteria, and the Proteobacteria proportion represented >50% of the bacterial community. The Actinobacteria proportion decreased, but Proteobacteria and Acidobacteria proportions increased with increasing biochar amounts. Fungi in tobaccoplanting soils were mainly Ascomycota (>75%), but this proportion decreased as the biochar amount increased.However, Zygomycota and Basidiomycota proportions increased with increasing biochar amounts. Therefore, biochar application could improve the soil nutrient status and affect microbial community structure. Rice straw biochar application promoted fungal community diversity in tobacco-planting soils.

“…Koyama and Hayashi [59] also found a similar decrease in the Mg concentrations in rice straw tissue with an increase in rice husk biochar addition rate up to 2 kg m −2 (equivalent to 20 t ha −1 ). Our result also agrees Syuhada et al [60] who found out that biochar addition at 10 and 15 g kg −1 from oil palm feedstock applied on to podsol soils significantly increased concentration and uptake of K while decreasing the Mg concentration in maize tissue. They attributed the low uptake of Mg to competitive ion effect between the uptakes of Mg and K. Although we did not measure the dry matter yield, the increased nutrient concentrations of K also implies high uptake of K since nutrient uptake is governed by the concentration of nutrients in plant tissues and the dry matter yield.…”

Sesame is an important oilseed crop cultivated worldwide. However, research has focused on biochar effects on grain crops and vegetable and there is still a scarcity of information of biochar addition on sesame. This study was to assess the effect of biochar addition on sesame performance, with a specific emphasis on growth, yield, leaf nutrient concentration, seed mineral nutrients, and soil physicochemical properties. A field experiment was conducted on an upland field converted from paddy at Tottori Prefecture, Japan. Rice husk biochar was added to sesame cropping at rates of 0 (F), 20 (F+20B), 50 (F+50B) and 100 (F+100B) t ha −1 and combined with NPK fertilization in a first cropping and a second cropping field in 2017. Biochar addition increased plant height, yield and the total number of seeds per plant more in the first cropping than in the second cropping. The F+50B significantly increased seed yield by 35.0% in the first cropping whereas the F+20B non-significantly increased seed yield by 25.1% in the second cropping. At increasing biochar rates, plant K significantly increased while decreasing Mg whereas N and crude protein, P and Ca were non-significantly higher compared to the control. Soil porosity and bulk density improved with biochar addition while pH, exchangeable K, total N, C/N ratio and CEC significantly increased with biochar, but the effect faded in the second cropping. Conversely exchangeable Mg and its plant tissue concentration decreased due to competitive ion effect of high K from the biochar. Biochar addition is effective for increasing nutrient availability especially K for sesame while improving soil physicochemical properties to increase seed yield, growth and seed mineral quality.Agronomy 2019, 9, 55 2 of 20 (13.5%), ash (5%) [2], and mineral components, such as K (815 mg/100 g), P (647 mg/100 g), Mg (579 mg/100 g) and Ca (415 mg/100 g) [3]. This contributes to its health and nutritional benefits. Therefore, demand for sesame seeds is increasing due to the increasing knowledge on their dietary and health benefits, but there has been limited research on sesame evidenced by low yield in most growing areas hence hampering its adoption and expansion in the world [4]. Although sesame has been reconsidered a local specialty crop in Japan [5], the production of sesame is still low. For instance, the Food and Agriculture Organization (FAO) in 2016 estimated that 11 tons of sesame seeds were produced from an area of 21 hectares [6]. With the increase in abandoned paddy fields estimated at 360,000 ha by the year 2010, farmers were encouraged to convert such fields into cultivation of upland crops, such as wheat and soybeans [7,8], including sesame. However, crop yield on upland fields converted from paddy may decrease due to declining soil fertility status of the paddy soils that could require soil amendment with organic materials [9].Biochar is a soil amendment produced from thermal decomposition of organic materials through pyrolysis and it has the potential to increase crop yields [10,11]....

“…Application of BCs might also improve soil mineral K release by enhancing the activity of K-dissolving bacteria and facilitating K uptake by crops [51]. Syuhada et al [52] found that the K content in corn tissue was significantly higher but its tissue content of N, Ca, and Mg was lower in BC-amended plants than that of the control. They attributed the high tissue K content in BC treatments to increasing exchangeable soil K.…”

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
