“…Species-level differences in uptake and storage of soil nutrients are another possible mechanism of tree species influence on soil acidity (Fujii et al 2008). For example, species could reduce nitrate leaching and resulting acidity by maintaining high biomass N stocks that serve as a competing 'loss' of DIN from the soil profile over time.…”

“…The unsaturated hydraulic conductivity and soil water pressure heads at depths of 5, 15 and 45 cm were estimated using the saturated hydraulic conductivity, and water retention curves of soil and volumetric water content monitored at each depth at 30-min intervals (Mualem andDagan 1978, Van Genuchten 1980). Details of the calculations of soil water fluxes are presented in our recent study (Fujii et al 2008). The soil water fluxes for each month were calculated by summing the half-hourly water fluxes.…”

“…The vegetation is dominated by Quercus serrata and Castanopsis cuspidate, with little understory vegetation. The Inceptisols are affected by brunification and weak podzolization (Fujii et al 2008). The higher contents of Alo and Feo in surface soil horizons suggest that Al and Fe oxides were immobilized in an organo-mineral complex (Table 2), as would occur during brunification (Ugolini et al 1990).…”

Leaching of dissolved organic matter (DOM) is an important process in the translocation and stabilization of organic carbon (C) and in influencing nitrogen (N) availability in forest soils. The roles of DOM in soil carbon and nitrogen cycles were evaluated by quantifying the fluxes of dissolved organic carbon (DOC) and nitrogen (DON) entering and leaving the organic (O), A and B horizons. In Spodosol and Inceptisol soils, DOC fluxes were highest in the O horizon (149 to 344 kg C ha À1 yr À1 ), decreasing in the A and B horizons. In Andisol soils, DOC fluxes were low throughout the profile because of low DOC production in the O horizon (53 kg C ha À1 yr À1) and the high adsorption capacity of amorphous aluminum (Al) and iron (Fe) (hydr)oxides in the mineral horizons. In Spodosol soil, DOC from the O horizon represented a large proportion of C input into the mineral soil, whereas this contribution appeared to be small in Andisol soil. The DOM was enriched in nitrogen during decomposition and humification of the foliar litter, but DON was a small proportion (5-31%) of total dissolved nitrogen (TDN) in surface soil solutions. The narrow DOC/DON and DON/TDN ratios were attributable to the low C/N ratios of the foliar litter (33-40). It was quantitatively shown that the importance of DOM in C and N cycles in forest soils varied depending on soil types and litter C/N ratio.

“…A maior parte dos solos do planeta desenvolveu-se sob florestas, cuja influência foi significativa para o estabelecimento de certas características edáficas (PRITCHETT e FISCHER, 1987), como o grau de acidificação e de dessilicação, por ter atuado como fator de formação do solo e, assim, interferido nos processos pedogenéticos gerais e específicos (FUJII et al, 2008). As primeiras observações das relações entre solo e floresta foram realizadas pelos habitantes primitivos desta.…”

RESUMOO setor florestal desempenha um papel importante no contexto socioeconômico e ambiental brasileiro, por isso o avanço no conhecimento sobre os solos florestais torna-se essencial para o uso sustentável dos recursos naturais, seja como base de conservação do patrimônio natural ou como recurso para o desenvolvimento econômico. Solo florestal pode ser definido como aquele cuja pedogênese está associada à influência de uma tipologia florestal ou o que apresenta uma cobertura de floresta natural ou plantada. Diferenciar solos florestais daqueles ocupados com outros usos auxilia na compreensão das possíveis alterações relacionadas à cobertura vegetal e no desenvolvimento de melhores estratégias de manejo para o uso do solo e da floresta. No entanto, ainda não há um consenso em torno do termo, uma vez que o solo apresenta variações de acordo com as características da floresta, estimulando a discussão relativa à sua interpretação e aplicabilidade. A presente revisão de literatura tem por objetivo analisar a utilização do conceito de solo florestal, ressaltando características de diferenciação e sua relação com o tipo de cobertura, natural ou plantada. Aspectos relativos à deposição, qualidade e manejo de resíduos, ciclagem de nutrientes, compactação e produtividade de sítio são enfatizados. Conclui-se que o conceito de solo florestal é amplamente utilizado na literatura específica e útil para o levantamento de informações e de planejamento sustentável de uso do solo e da floresta. A melhoria do conhecimento sobre esse recurso abre a possibilidade de se criar uma identidade comum, o que facilita estudos comparativos de características específicas, fortalecendo a pesquisa em torno do tema. Palavras-chave: pedogênese; cobertura florestal; ciclagem de nutrientes; qualidade do solo. ABSTRACTThe forestry sector plays an important role in the socioeconomic and environmental Brazilian context, therefore the improvement of the knowledge about forest soil becomes essential for its sustainable use as a conservation base of natural heritage as resource for economical development. Forest soil can be characterized by pedogenesis occurred under influence of a forestry typology or under a currently natural or cultivated forest coverage. Differentiating forest soils from those occupied with other uses helps the understanding of possible alterations related to vegetal coverage and the developing of better management strategies to soil and forest use. Nevertheless, there is no consensus about this term because the soils present variations according to the forest characteristics, stimulating the discussion concerning its interpretation and applicability. This review aimed to analyze the utilization of forest soil concept, highlighting the differentiation characteristics and the relation with coverage type, natural or cultivated. Aspects related to deposition, quality and management of residues, nutrients cycling, soil compaction and site productivity are emphasized. The forest soil concept is widely used by specific literature and us...
