“…Meanwhile, the process of soil denitrification was completely carried on and the N 2 O was reverted to N 2 , thereby reducing the N 2 O emissions from the soil [60]. An average decrease of 36% of N 2 O fluxes under high soil moisture conditions, likely induced by the raised abundance of N 2 O-reducing bacteria [61]. Compared with the CK treatment, the cumulative emission of N 2 O significantly increased in both the NPK and biochar treatments under the two irrigation conditions, and this was related to the application of the nitrogen fertilizer [9].…”

In this study, we investigated the greenhouse gas emission under different application of biochar in the conditions of continuous flooding and water-saving irrigation in paddy fields, whereas, plant and soil carbon sequestration were considered in the calculation of net greenhouse gas emissions. The emission rates of methane (CH 4 ), carbon dioxide (CO 2 ), and nitrous oxide (N 2 O) gases were simultaneously monitored once every 7-10 days using the closed-chamber method. As a whole, the net greenhouse gas emission in the water-saving irrigation was more than that of the continuous flooding irrigation conditions. Compared with the water-saving irrigation, the continuous flooding irrigation significantly increased the CH 4 in the control (CK) and chemical fertilizer treatments (NPK). The CO 2 emissions increased in each treatment of the water-saving irrigation condition, especially in the chemical fertilizer treatments (NPK FW ). Similarly, the soil N 2 O emission was very sensitive to the water-saving irrigation condition. An interesting finding is that the biochar application in soils cut down the soil N 2 O emission more significantly than NPK FW in the water-saving irrigation condition while the effect of biochar increased under the continuous flooding irrigation condition.

“…Microorganisms are an important component of the soil ecosystem. The addition of biochar can change soil microbial abundance and diversity because (a) the mineral and labile carbon content in biochar can be used as a food resource for microbial growth (Gomez, Denef, Stewart, Zheng, & Cotrufo, ); (b) biochar may enhance soil aeration and alleviate soil compaction (Liu et al, ); (c) biochar may exert chemically mediated effects, including changes to soil acidity and cation exchange capacity, that may be more favorable to specific competitive microbes over others (McCormack, Ostle, Bardgett, Hopkins, & Vanbergen, ; Xu et al, ); (d) biochar might influence plant growth, which would indirectly affect rhizosphere microorganisms (Andrenelli et al, ; Luo & Gu, ); and (e) biochar can be used as a suitable habitat for the growth of microorganisms and avoid predators and water deficiency (Quilliam, Glanville, Wade, & Jones, ). Therefore, biochar may have varying effects on soil microbial communities (Imparato et al, ; Nielsen et al, ; Xu et al, ).…”

Biochar is an important soil conditioner. However, we have limited understanding of biochar effects on the microbial community traits of the rhizosphere and bulk soil in the field. The aim of this study was to examine the impacts of biochar amendment on microbial abundance and community in the rhizosphere and bulk soils in soybean‐growing fields. We applied 16S ribosomal RNA (rRNA) gene sequencing with an internal standard gene to quantitatively investigate biochar‐mediated changes in microbial composition and abundance in rhizosphere and bulk soils. The results indicated that the absolute abundance of bacterial taxa with internal standard can be more informative in describing soil microbial population distribution. A linear discriminant analysis effect size differential analysis showed that the biochar amendment significantly altered the soil microbial abundance and community composition. The bacteria in the rhizosphere soil showed more clear responses to biochar addition than the bacteria in the bulk soil. These results highlight the enhanced effect by biochar on bacterial population distribution in the rhizosphere. 16S rRNA gene sequencing with internal standard gene represents an effective method that can substantially improve 16S‐seq based microbiome studies by determining the 16S rRNA gene abundance and bacterial community composition simultaneously.

“…Aunque las especies vegetales son diferentes y los suelos son de regiones también diferentes, la dosis aplicada en el experimento del caso presente fue al menos cinco veces menor a la dosis de 20 Mg ha -1 y favoreció la altura de las plantas de avena. Liu et al (2017b) reportaron resultados similares con respecto a la variable AP en el cultivo de trigo. Ellos evaluaron dosis de 48 Mg ha -1 de BC elaborado con paja de maíz; el valor mayor que reportaron fue de 86 cm cuando aplicaron BC, representando 5% más AP que la relacionada al control, por lo que señalaron que, al incorporar BC al suelo, la porosidad mejoró al reducirse la densidad aparente, además de que el potasio aplicado se mantuvo disponible en mayor cantidad.…”

El suelo es un recurso imprescindible para la producción agrícola y, por lo tanto, requiere de condiciones adecuadas para favorecer una nutrición adecuada de los cultivos y generar mayores rendimientos. El biocarbón ha sido propuesto ampliamente para mejorar la calidad del suelo y la productividad de los cultivos. El objetivo del estudio fue evaluar los efectos del biocarbón sobre el rendimiento y calidad de la avena forrajera, en el periodo otoño-invierno 2016-2017. Un diseño de bloques al azar con cuatro repeticiones fue usado, el cual incluía tres tratamientos y un testigo: T0 = testigo absoluto; T1 = [fertilización convencional: (120‑60‑00 kg ha‑1)]; T2 = (2.25 Mg ha‑1 de biocarbón + fertilización convencional); T3 = (4 Mg ha-1 de biocarbón + fertilización convencional). El experimento se condujo en campo abierto con una densidad de siembra de 120 kg ha-1. Las variables evaluadas fueron: altura de planta (AP), materia verde (MV), materia seca (MS); f ibra detergente neutra (FDN), f ibra detergente ácida (FDA), proteína cruda (PC), nutrientes digestibles totales (NDT), digestibilidad de la materia seca (DMS). Los datos registrados se sometieron a análisis de varianza y las medias se compararon con la prueba de Tukey (P < 0.05). Diferencias estadísticas signif icativas (≤ 0.05) se observaron para AP y MV, donde T2 registró el mayor valor de 33 y 102%, respectivamente, frente al control. Se concluye que la aplicación de biocarbón influye positivamente sobre atributos de rendimiento de avena forrajera. Sin embargo, se deben realizar estudios más detallados, considerando condiciones distintas al presente estudio.
