“…On the contrary, some authors have reported no effect on soil pH following BC addition, particularly when produced at low PT (<350°C) and when amending either alkaline or saline soils (Novak et al, 2009;De La Rosa et al, 2014;Olmo et al, 2014). This may be reflective of the strong influence of PT on BC pH (Janus et al, 2015), and also of the soil CaCO3 buffering effect (Olmo et al, 2014).…”

“…Biochar may play an important role in mine land remediation based on its ability to increase pH, soil water retention, nutrient availability, and binding of heavy metals and thus support plant establishment and growth. Several studies have reviewed the potential ability of biochar to minimize off-site movement of heavy metals and to function as a neutralizing agent for acidified mine spoils [67][68][69]. These studies reported that biochar can bind heavy metals, ameliorate acidic soils, and improve soil health characteristics.…”

“…Commonly used soil amendments for remediating contaminated mine tailings include biosolids, manures, composts, digestates (i.e., the remains of anaerobic digesters), papermill sludges, yard, and wood wastes [12,69]. Although these amendments are effective in the short term, each eventually decomposes and thereby reduces their longterm remediation efficacy.…”

“…Las propiedades de los biochars son muy variables debido a los diferentes parametros que se pueden modificar para su producción (Janus et al, 2015). Entre los aspectos mas relevantes que influyen sobre las propiedades del biochar se encuentran, el tipo de biomasa empleada como materia prima, el tamaño de partícula, la temperatura, velocidad y tiempo de calentamiento y el tipo de proceso térmico (Barrow, 2012;.…”

“…Dichos compuestos no se degradan facilmente al aumentar la temperatura, como es el caso de la lignina (De La Rosa et al, 2014;Blazquez et al, 2014). El aumento del contenido en carbono de los biochars al aumentar la temperatura de producción, se debe a un mayor grado de carbonización, así como a la reducción de los contenidos en hidrógeno y oxígeno resultante de la volatilización de compuestos ligeros (CO 2 y CH 4 ) y a la formación de nuevos enlaces mediante reacciones de polimerización y condensación (Janus et al, 2015;Dume et al, 2015).…”
