Soil Macrofauna as a Soil Quality Indicator in Native and replanted Araucaria angustifolia Forests

A Biological Indicator for Soil Quality

There is a growing interest in instruments to assess the present and to predict the future performance of ecosystems that are or may be influenced by human activities.

Evaluation of β-Glucosidase Activity as a Soil Quality Indicator for the Soil Management Assessment Framework

Soil organic matter as sole indicator of soil degradation.

Soil organic matter (SOM) is known to play vital roles in the maintenance and improvement of many soil properties and processes. These roles, which largely influence soil functions, are a pool of specific contributions of different components of SOM. The soil functions, in turn, normally define the level of soil degradation, viewed as quantifiable temporal changes in a soil that impairs its qua...

Soil organic matter stratification ratio as an indicator of soil quality

Soil quality is a concept based on the premise that management can deteriorate, stabilize, or improve soil ecosystem functions. It is hypothesized that the degree of stratification of soil organic C and N pools with soil depth, expressed as a ratio, could indicate soil quality or soil ecosystem functioning, because surface organic matter is essential to erosion control, water infiltration, and ...

Species richness of arbuscular mycorrhizal fungi in forests with Araucaria in Southern Brazil

(Species richness of arbuscular mycorrhizal fungi in forests with Araucaria in Southern Brazil). This study aimed to characterize species richness of arbuscular mycorrhizal fungi (AMF) in three distinct forests with Araucaria angustifolia (native forest, reforestation with A. angustifolia and plantation with Pinus taeda) in the “Floresta Nacional de São Francisco de Paula”, State of Rio Grande ...
