“…Therefore, it is expected that the heterocyclic N of HTC char would behave in a similar way to the pyrolytic heterocyclic N. A comparison of the results of this study with literature reveals that the effects of HTC char application to agricultural soils on the emissions of N2O are unclear (Table 2). Increased (Kammann et al 2012) and reduced (Malghani et al 2013;Dicke et al 2014) emissions of N2O after fertilizer application compared with control treatments have been documented; however, cases of no difference between HTC and control treatments have been reported by Schimmelpfennig et al (2014), which accords with our results. Reasons for this could involve the production conditions of HTC, the feedstock, the incubation conditions, and the soil used.…”

“…Hydrothermally carbonized char made of digestate and wheat straw reduced emissions of N2O (Dicke et al 2014), whereas emissions after adding HTC char made of hemp dust did not differ significantly from those of the control sample. Furthermore, Schimmelpfennig et al (2014) observed no difference between treatments with or without HTC char and concluded that this was caused by the moisture regimes compared with Kammann et al (2012). In different forest soils, Malghani et al (2013) observed both increased and decreased emissions of N2O, compared with the HTC charfree soil.…”

“…A szakirodalom egy jelentős része pedig a bioszén hatásairól nyújt információt a talaj fizikai tulajdonságaira nézve, mint például pó-rusméret eloszlása, porozitása, aggregátumstabilitása, a talaj térfogattömege, valamint víztartó képessége (ZHANG et al, 2012;SCHIMMELPFENNIG et al, 2014;HERATH, 2013). Bioszén használatával a talaj tápanyagtartalma, vízgazdálkodása javulhat (NGUYEN et al, 2014;SCHIMMELPFENNIG et al, 2014;DOWNIE et al, 2009;CHAN et al, 2007;HARDIE et al, 2014) azáltal, hogy elősegíti az aggregá-tum-képződést, javítja az aggregátum-stabilitást, így módosítva a talaj pórusainak eloszlását (DOWNIE et al, 2009;JONES et al, 2011;HARDIE et al, 2014).…”

“…Because biochar is not always applied purely but also mixed with manures, minerals fertilizers and compost [18][19][20][21], another wealth of data becomes available from trails that, however, also contribute to the complexity to explain the observed effects.…”
