“…The work done by [28] showed highly alkaline pH which indicates that the sample was fresh and less exposed to environment. The research done by [29] showed electrical conductivity of 2.20 mS/cm which is higher than present work. The value of electrical conductivity is directly proportional to the concentration of anions or cations in the sample degree of weathering in natural weathering.…”

“…El aumento de CE observado, se debe a la presencia de sales solubles aportados por el biochar (Zornoza et al, 2016), y en especial con BG 600/3. El incremento tanto de pH como de CE en los suelos tras el aporte de biochar se ha visto en muchos estudios anteriores (Atkinson, Fitzgerald, & Hipps, 2010;Melo et al, 2016;Méndez et al, 2012;Paz-Ferreiro et al, 2014;Rees, Simonnot, & Morel, 2014), incluso en suelos contaminados por minería (Kelly et al, 2014;Moreno-Barriga et al, 2017;Wiszniewska et al, 2016). En concreto, Rees et al ( 2014), al igual que en este estudio, observaron que, la adición de biochar procedente de madera, en el suelo con pH ácido, incrementaba su pH de manera significativa, mientras que, en un suelo con un pH inicial alcalino, no existína diferencias significativas tras la enmienda.…”

“…Por otro lado, el aporte de biochar de estiércol de conejo y gallinaza pirolizados a 600ºC disminuye o no tiene efectos significativos sobre la tasa de respiración de la mayoría de los suelos y lodos estudiados. De manera similar a este estudio Moreno- Barriga et al (2017) no observaron efectos significativos en la respiración de un suelo de relave de minería enmendado con biochar de purín de cerdo pirolizado a 500ºC tras 90 días de incubación. Zimmerman et al (2011) concluyeron que la mineralización del carbono generalmente es menor de la esperada para suelos tratados con biochar preparados a temperaturas altas (500-600•C).…”
