ABSTRACT Land-use changes from native pastures to forest plantations in humid temperate areas have raised concerns about their potential impact on the environment. This study aimed to assess the effects of such changes on soil water properties, focusing on the impact of the forest species planted and their relationship with changes in soil C content. Specifically, we aimed to identify the development of surficial soil hydrophobicity and changes in soil water holding capacity. A long-term forest experiment with variable planting […]

ABSTRACT Soil microbiota is an important component of the forest biomes, playing important roles in the soil aggregation and cycling of nutrients. Among the soil microorganisms stand out the yeasts, which are unicellular fungi involved in important soil ecological processes. The Brazilian Atlantic Forest is one of the main biodiversity hotspots in the world, and the effect of altitudinal gradient on the distribution patterns of yeast species across this ecosystem has not yet been addressed. Thus, this study aimed to […]

Soil organic matter (SOM) is one of the major reservoirs of carbon on Earth and is one of the key contributors to the carbon cycle. Peatlands are natural accumulators of organic matter commonly derived from decomposing plant residues in water-saturated environments, and represent an initial stage of a much longer pedogenic pathway leading to carbonification. The soil biomass markedly influences the global carbon cycle, accounting for approximately 85 % of all carbon on the Earth’s surface. Plant tissues are mainly […]

Before recommending biosolids at large scale for forest plantations it is necessary to have an ample understanding of its effects on soil and plant. Thus, it was evaluated the soil fertility, nutritional status and growth of a Eucalyptus grandis plantation fertilized with biosolid (bios). The trial was established at the Experimental Station of Forest Sciences of Itatinga – ESALQ/USP (São Paulo State, Brazil). The experimental design was in complete randomized blocks, with 4 replicates. There were nine treatments, namely: (1) control; […]

A cartographic simulation in a Geographical Information System (GIS) was used to evaluate the environmental impacts of different forest management strategies on a watershed scale. The project was conducted in a small (2 km2) watershed located at northern coast of the State of Espírito Santo, Brazil, which is inserted in an area of eucalypt-clone plantation comprised by the agro-industrial complex Aracruz Celulose S.A. Potential impacts were assessed by applying the Universal Soil Loss Equation (USLE) in a GIS, where different […]
