“…All statistical tests were performed with SigmaPlot (Systat Inc., Chicago, IL, USA). Several studies demonstrated that the environmental function of biochar in soil vary depending on the physical and chemical characteristics of the biochar which depend on feedstock used in the production of biochar and production conditions (Smider and Singh, 2014; Sun et al, 2014; Nansubuga et al, 2015).…”

“…The physical and chemical properties of biochars derived from different sources of feedstock can vary tremendously leading to the high variability observed in terms of their effects on soil fertility (Sun et al, 2014;Nansubuga et al, 2015). In addition to the many sources of feedstock, the thermal profile and the geographic variations in soil type and climate are some of the chief sources of variability when looking to benefits of biochar as a soil amendment (Wang et al, 2016).…”

“…Sludge resulting from wastewater treatment can create significant environmental problems related to air emissions, soil and water resources contamination, so this waste requires proper treatment and efficient management [7]. To attenuate the negative effects of direct application of sewage sludge on agricultural land, its transformation into biochar by the pyrolysis process constitutes an efficient method of recycling this waste [8]. The pyrolysis process significantly reduces the weight and volume of the sludge, the heavy metals are immobilized and their bioavailability in soil is reduced, pathogens and unpleasant smell are removed, resulting a solid product that has a positive impact on the soil properties and also on plant growth [8][9][10].…”
