“…However, the continual use of concentrated nitrogen (N) and phosphorus (P) fertilizer formulations that do not contain S, reduced use of S-containing pesticides, greater export of S from soil in high crop yields, reduced S input through rainwater, and the reduction of emissions of S dioxide (SO 2 ) from fossil fuel burning to the atmosphere has led to an increase of S deficiency in soils (Wainwright, 1984). In some specific areas, such as the Brazilian cerrado, S deficiency in soils can occur naturally (McClung & Freitas, 1959;Ribeiro Jr. et al, 2001).…”

“…As limitações que a falta de S pode ocasionar na produção vegetal em solos brasileiros não é fato recente. Já no final da década de 50, vários trabalhos (McClung et al, 1958(McClung et al, , 1961McClung & Freitas, 1959) evidenciavam a baixa capacidade desses solos em suprir as necessidades de S devido aos seus baixos teores de matéria orgânica, uma vez que aproximadamente 90% do S do solo encontra-se na forma orgânica (Wolffenbüttel & Tedesco, 1981).…”

“…As limitações que a falta de enxofre podem causar a produção agrícola em solos brasileiros foram relatadas por diversos trabalhos (McCLUNG et al, 1958(McCLUNG et al, , 1961FREITAS, 1959) que evidenciaram a baixa capacidade dos solos brasileiros em atender as exigências de S dos vegetais (WOLFFENBÜTTEL; TEDESCO, 1981;TABATABAI, 1984, MALAVOLTA, 2006…”
