There is no information about the diversity of springtails associated with Araucaria angustifolia (Bert.) O. Kuntze forests in Brazil. This study was carried out to evaluate the potential of springtail family diversity as a soil quality indicator and to separate different Araucaria areas, using soil chemical and microbiological attributes as explanatory variables. The study was conducted in four areas of: 1. native forest with predominance of Araucaria (NF); 2. Araucaria reforestation (R); 3. Araucaria reforestation burnt by an accidental fire […]

Soil quality can change along the time due to natural events or anthropic activities. The use of organic management practices reduces soil tillage and favors the recovery of soil physical and chemical properties. The objective of this study was to compare the physical, chemical and biological properties of cultivated soils under organic system or conventional tillage system. Six organic and three conventional cultivated areas were selected and soil samples collected in the layers 0-10, 10-20 and 20-30 cm. Physical, chemical […]
