“…Besides increasing N retention and water use efficiency, biochar application may have also better synchronize N release with plant uptake (Mukherjee et al, 2011;Mandal et al, 2016;Esfandbod et al, 2017), consistent with the increase in total N uptake observed in this study. The inorganic N may have enhanced immediate availability of N, whereas the subsequent release of N from biochar could have coincided with peak wheat N demand (Kameyama et al, 2012;Yang et al, 2017).…”

“…Pyrolysis leads to high aromaticity of C, which makes biochar more resilient to degradation (Kuzyakov et al, 2014;Domingues et al, 2017). In addition, biochar has high cation exchange capacity, with diverse acidic and basic functional groups, which helps to adsorb nutrient on its surface and better synchronize their release with plant uptake (Mukherjee et al, 2011;Mandal et al, 2016;Esfandbod et al, 2017). In addition, biochar has high cation exchange capacity, with diverse acidic and basic functional groups, which helps to adsorb nutrient on its surface and better synchronize their release with plant uptake (Mukherjee et al, 2011;Mandal et al, 2016;Esfandbod et al, 2017).…”

“…Thus, biochar-treated soils have high C residence time. In addition, biochar has high cation exchange capacity, with diverse acidic and basic functional groups, which helps to adsorb nutrient on its surface and better synchronize their release with plant uptake (Mukherjee et al, 2011;Mandal et al, 2016;Esfandbod et al, 2017). In addition to biochar application, the retention of crop residues on soils can serve as physical barriers to reduce soil erosion and concurrent N related losses.…”

Tillage and Biochar Effects on Wheat Productivity under Arid Conditions

Urea is an important source of inorganic N under wheat (Triticum aestivum L.) production system in Multan, Pakistan. However, the average N loss is high, ranging from 22 to 53% of applied N, which poses adverse environmental impacts. Reduced tillage and combined application of biochar and optimal N fertilizer could improve wheat productivity and reduce N losses. We evaluated the effects of two tillage (conventional and reduced tillage), two biochar (no biochar and poultry waste biochar), and three inorganic N rate (0, 60, and 120 kg ha−1) treatments on productivity and economic profitability of wheat production for two continuous growing seasons (2014–2015 and 2015–2016). Generally, reduced tillage increased wheat grain yield, protein content, and total N uptake by 0.2 Mg ha−1, 3.0 kg kg−1, and 37.0 kg ha−1, respectively, when compared with conventional tillage. Biochar application increased wheat grain yield, protein content, and total N uptake by 0.3 Mg ha−1, 6.8 kg kg−1, and 38.6 kg ha−1, respectively, compared with no‐biochar plots. Reduced tillage was economically profitable within the two cropping seasons, but biochar application was not, because of the high price of biochar (US$1.00 kg−1 biochar) and application rate (10 Mg biochar ha−1). Overall, wheat production under reduced tillage, no biochar, and the 60‐kg N ha−1 rate resulted in the greatest economic profit in this study.

“…Application of biochar to residue can reduce NH 3 volatilisation substantially, because of its adsorption capacity for NH 4 + and NH 3 (Chen et al 2010a). Esfandbod et al (2017) found that application of acidic biochar to residue reduced the cumulative loss of NH 3 and that KCl-extractable NH 4 + -N was also much higher in this treatment compared with control or where alkaline biochars were used. From a practical viewpoint, incorporation of fertiliser NH 4 + into the topsoil layer by tillage will greatly reduce losses by reducing NH 3 concentrations in soil solution near the soil surface (Jones and Haynes 2011).…”

Soil quality and vegetation performance indicators for sustainable rehabilitation of bauxite residue disposal areas: a review

et al. 2019

View full text Add to dashboard Cite

The generation of bauxite residue, the by-product of alumina manufacture from bauxite ore, has increased to a global stockpile of some 3 billion tonnes. In the absence of significant reuse options, the bulk of this residue is contained within bauxite residue disposal areas (BRDAs), which can occupy a significant footprint and pose potential environmental risk. Rehabilitation (amendment and vegetation establishment) is viewed as a significant strategy for eventual closure of the BRDAs. Major limitations to plant growth in residue include high pH, salinity, and sodicity, as well as deficiencies of macro- and micronutrients and potentially elevated levels of trace elements. The physical properties are also problematic as residue mud consolidates to form a solid mass that waterlogs easily or dries to form a massive structure, whereas sand has a very low water- and nutrient-holding capacity. A variety of techniques have been trialled at the pot level and at the field scale to bring about reductions in residue alkalinity and sodicity to promote plant establishment, with gypsum amendment viewed as the most promising. Other amendment strategies include use of organic additions or fertiliser applications, and a combined approach can lead to improved residue properties and successful plant establishment. Few reports have focused on longer term plant growth, self-propagation, and residue interactions under field conditions. There is some evidence that rehabilitated residue can support vegetation growth and soil development in the short to medium term (~15 years), but key issues such as nutrient availability and plant uptake require further study. Although rehabilitated residue can support diverse microbial communities and demonstrate trajectory analogous to soil, the ability of rehabilitated residue to support soil biota and key ecosystem processes warrants further study. The bioavailability of trace elements within rehabilitated sites and potential food chain transfer are relatively unexplored. These areas need careful study before definitive statements can be made regarding the sustainability of residue rehabilitation strategies.

“…Cuando el BC ha sido incorporado al suelo puede mejorar su calidad (Ajayi et al, 2016;Ye et al, 2016;Biederman et al, 2017), puesto que ha influido positivamente sobre sus propiedades físicas, químicas y bióticas (Mukherjee y Lal, 2014;Coumaravel et al, 2015;Subedi et al, 2016;Mia et al, 2017), mejorando los contenidos de materia orgánica, aireación, textura (Ajayi et al, 2016), retención de humedad, y disponibilidad de elementos químicos nutritivos para las plantas (Aker et al, 2013;Kanthle et al, 2016;Kim et al, 2016;Biederman et al, 2017;Esfadbod et al, 2017).

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.
