“…and Bacillus sp. Additionally, formulation with biochar stimulated seed germination, plant growth and yield of tomato, as well as soil biological activity (Tripti et al 2017). Characteristics of biochar such as source material, pyrolysis temperature and granulate size can further influence the interaction among biochar and microbial colonization.…”

Biochar has been used widely as a soil amendment to improve plant growth, nutrient acquisition, stress tolerance and to improve soil biological, chemical and physical properties. Several studies suggest biochar as a carrier for bacterial inoculants under various climatic and environmental conditions because of the properties that favour microbial life. Biochar is rich in organic carbon, contains nutrients, such as N, P, K, has a high porosity, and high water-holding capacity. In this review, we synthesise results on the effectiveness of biochar as a carrier for inoculum in pot and field conditions. Biochar as a carrier supported a high survival rate of introduced bacteria and significantly increased colonization in the plant rhizosphere. Soil microbes are known to play an essential role in soil biochemical processes, and nutrient cycles; improve plant stress tolerance, and nutrient acquisition through their ability to fix atmospheric nitrogen, solubilize phosphate, or by enhancing decomposition of plant residues. Moreover, biochar-based inoculants increased root and shoot biomass, nodulation and nutrient uptake of plants in pot and field experiments. Biochar-based inoculants were also effective in enhancing plant growth and grain yield in pot and field experiments. These studies demonstrate that biochar can be considered as a suitable carrier or formulation of bacterial inoculants even in hostile environments and might contribute to replace other commercially used materials successfully. Biochar-based rhizobial inoculants can significantly improve the symbiotic performance of legumes with rhizobia which may reduce N fertilizer demand and thus promote the sustainability of crop production.

“…The size of the zone of solubilization on agar and the corresponding phosphate solubilizing activity in broth (µg/ml), measured after 5 days of incubation, were found to be in conformity, similar results were reported by Pandey et al 28 (Table -1). Although phosphate solubilizing activity measured in the form of halo zone on agar and estimated using broth culture are not always found to be similar 29 .The pH of the broth was found to decline from initial 7±2 to 3.21, lowering of pH coincide with an increase in efficiency of phosphate solubilizing activity 20 . Research work of Vyas et al and Vassileva et al suggested that decrease in the pH of culture filtrate containing inorganic phosphate is due to the secretion of organic acids by bacteria in the culture media 30,31 .…”

“…El BC ha llegado a actuar como inmovilizador de oligoelementos contaminantes (Jones et al, 2016) y también ha mejorado aspectos relacionados con la actividad enzimática (Wang et al, 2015). Por otro lado, el BC ha influido positivamente sobre las poblaciones y la actividad de los microorganismos benéf icos para las especies vegetales (Akhtar et al, 2015;Liao et al, 2016;Tripti et al, 2017). Por consiguiente, impactos positivos sobre la germinación (Clay et al, 2016), crecimiento y desarrollo de los cultivos (Pérez- Salas et al, 2013;Fawad et al, 2017;Liu et al, 2017a), y producción de biomasa pueden ser generados (Lou et al, 2016).…”

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.
