“…This result can be associated with the high ρ b and a consequent increase in the soil Mic that was noted in the remnant forest plot F5D. The soil attributes and K s values in remnant forest sites could be explained by the longer time that these forests have remained undisturbed, which allows a better soil structure to develop and the storage of more soil carbon [19,66]. These findings are in agreement with those reported by several other studies in the Atlantic Forest [63,65].…”

“…The soil texture, understory vegetation ( Figure 1) and intensity of past land use were different in the restored forest sites (R3 and R4), and these are the most likely reasons for the differences in soil attributes and K s values between both restored forests [23,66]. Also, it is important to underscore that this result could have been influenced by possible soil compaction during mechanized soil preparation during the forest restoration [67].…”

Knowledge of soil hydraulic properties after forest restoration is essential for understanding the recovery of hydrological processes, such as water infiltration. An increase of forest cover may improve water infiltration and soil hydraulic properties, but little is known about the response and extent to which forest restoration can affect these properties. The purpose of this study was to investigate the effect of forest restoration on surface-saturated soil hydraulic conductivity (K s ), and to verify the K s recovery to the pre-disturbance soil conditions. We sampled field K s at the surface in Campinas municipality, São Paulo State, Brazil, at 18 plots under three land-cover types: (i) a pasture; (ii) a restored forest using a high-diversity mix of plantings (85 regional native species) of 9 years of age; and (iii) a remnant forest patch. We used the Beerkan method for soil hydraulic characterization. Bulk density (ρ b ), soil organic carbon content (OC), soil porosity and particle size data were also sampled. We found considerable differences in soil hydraulic properties between land-cover classes. The highest K s were observed in remnant forest sites and the lowest K s were associated with pasture sites. The K s recovery differs markedly between restored forests. Our results strongly suggest that soil attributes and K s recovery are influenced by the duration and intensity of land use prior to forest restoration. Attention needs to be given to management activities before, during and after forest restoration, especially where the soil is still compacted and K s is low.

“…The necessity to expand the knowledge of soils under native vegetation and their relationship has been recognized as a research priority by several researchers (Lima et al, 2011;Cooper et al, 2012;Santos-Filho et al, 2013). The close relationship between soil attributes and forest composition has long been reported in the literature (Sollins, 1998), and SHP have been considered an important factor to be considered in studies involving soil-plant relationships (Ruggiero et al, 2002;Quesada et al, 2004;Oliveira et al, 2005).…”

Knowledge of the hydraulic properties of the soil is of crucial importance to an understanding of the interactions between vegetation, soil and water. There is little information available about the hydraulic properties of Podzol soils found in tropical regions. The aim of this study was to present the soil morphology and hydraulic properties of a toposequence situated in a permanent plot at the Ilha do Cardoso State Park (Cananéia, SP, Brazil). Ultradetailed soil maps were used to define a toposequence inside the permanent plot. Five profiles, representing the main types of soil, were opened along the toposequence, in which Podzols are dominant.The levels of bulk density, sand content, porosity and permeability in these soils were all high.Consequently, these soils have a high level of hydraulic conductivity with low water retention. This behavior undergoes an alteration in the Bh and Bs horizons due to the accumulation of organic and metallic compounds and a changing structure that modifies the pore distribution. Furthermore, the characterization of the hydro-physical functioning of soils in natural environments is an important source of encouragement to further investigative study of soil water dynamics and its relationship to the native vegetation.

SUMMARYThe concept of soil quality is currently the subject of great discussion due to the interaction of soil with the environment (soil-plant-atmosphere) and practices of human intervention. However, concepts of soil quality relate quality to agricultural productivity, but assessment of soil quality in an agronomic context may be different from its assessment in natural areas. The aim of this study was to assess physical quality indices, the S index, soil aeration capacity (ACt/Pt), and water storage capacity (FC/Pt) of the soil from a permanent plot in the Caetetus Ecological Reserve (Galia, São Paulo, Brazil) under a seasonal semideciduous forest and compare them with the reference values for soil physical quality found in the literature. Water retention curves were used for that purpose. The S values found were higher than the proposed limit for soil physical quality (0.035). The A and E horizons showed the highest values because their sandy texture leads to a high slope of the water retention curve. The B horizons showed the lowest S values because their natural density leads to a lower slope of the water retention curve. The values found for ACt/Pt and FC/Pt were higher and lower than the idealized limits. The values obtained from these indices under natural vegetation can provide reference values for soils with similar properties that undergo changes due to anthropic activities. All the indices evaluated were effective in differentiating the effects of soil horizons in the natural hydro-physical functioning of the soils under study.Index terms: S index, ACt/Pt, FC/Pt, water retention curve. RESUMO: AVALIAÇÃO DE ÍNDICES DE QUALIDADE FÍSICA DO SOLO SOB FLORESTA ESTACIONAL SEMIDECIDUALO conceito de qualidade do solo é muito discutido atualmente em razão das relações do solo com o meio ambiente (solo-planta-atmosfera) e das práticas intervencionistas do homem. Esse conceito relaciona a qualidade com a produtividade agrícola, mas sua avaliação em um contexto agronômico pode ser diferente em ecossistema natural. Este estudo teve como objetivo avaliar os índices de qualidade física do solo, o índice S, a capacidade de aeração do solo (ACt/Pt) e a capacidade de armazenamento de água do solo (CC/Pt) da parcela permanente localizada na Estação Experimental de Caetetus em Galia, São Paulo, Brasil, sob Floresta Estacional Semidecidual e compará-los com valores de referência de índices de qualidade física do solo encontrados na literatura. Para tanto, curvas de retenção de água foram utilizadas para o cálculo desses índices. Os valores do índice S encontrados foram superiores ao limite proposto de qualidade física do solo (0,035). Os horizontes A e E apresentaram os valores mais altos, pois sua textura arenosa refletiu em elevada inclinação da curva de retenção. Os horizontes B evidenciaram os menores valores de S, pois seu adensamento natural refletiu curvas de retenção com menor inclinação. Os valores de ACt/Pt e CC/Pt foram maiores e menores que os valores definidos como ideais. Os índices de qualidade física do ...
