“…Therefore, C loss due to HF treatment is usually related to SOM associated to mineral surfaces. 22,28 As expected, C and N contents of whole soil (C and N), in all three environments, increased after HF treatment (Table 4) indicating that the inorganic components were mostly dissolved. 7 The recovered mass (M R ) after HF treatment of whole soil ranged from between 21 and 33% and these results are related to the samples' sand (granulometric fraction with diameter < 53 μm) content which was around 40%.…”

“…Nesse período e em outros estudos, os resíduos remanescentes têm desempenhado importante papel no sistema de plantio direto como, por exemplo, no controle da erosão, na conservação da fertilidade e na umidade do solo Potes et al, 2010;Souza et al, 2009).…”

“…Essa translocação deve-se à funcionalização hidrofílica desses compostos conferida por grupos carboxílicos e nitrogenados (Kalbitz et al, 2000). Resultados semelhantes também foram observados em Cambissolos e Neossolos, desenvolvidos de rochas eruptivas do sul do Brasil (Potes et al, 2010).…”
