ABSTRACT No-tillage system (NTS) plays a prominent role in conservation agriculture, however, its benefits can be further improved by adopting complementary soil management and conservation practices, such as using autumnal cover crops, contour seeding, and terraces. This study aimed to evaluate how soil biological activity responds to soil management and conservation systems. The treatments consisted of three macroplots with an area of 11.000 m2 each, as follows: a) Non-Terraced catchment (NTC), cultivated in NTS similar to most farmers of the […]

ABSTRACT Given the influence of edaphic macrofauna in the physical, chemical, and biological processes that sustain the organic matter cycle in the soil of tropical ecosystems, this study aimed to evaluate the effect of the sequence: Secondary Forest – Pasture – Eucalyptus monoculture on the macrofauna structure in Southeast of Pará State, Brazil. In each land use system, two 350 m transect were taken. The data was collected in 8 sampling sites, which were 50 m apart in each transect […]

ABSTRACT Intensive land use can affect macrofaunal biodiversity, which is a property that can be used as a soil quality indicator. This study evaluated the abundance and diversity of soil macrofauna and its relation to soil chemical and physical properties in five land use systems (LUS) in the eastern region of Santa Catarina. The following LUS were studied: native forest (NF), eucalyptus plantations (EP), perennial pasture (PP), integrated crop-livestock (ICL), and no-tillage cropping (NT). The macrofauna was quantified in 0.25 […]

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 […]

Sustainable soil use is becoming increasingly relevant given the increase of anthropic activities. In order to evaluate the soil quality, soil samples were collected from five areas: natural Cerrado (reference), native pasture, planted pasture, annual crops under conventional tillage and pine forest. The areas are located in the Federal District, Brazil, in a clayey Red Yellow Latosol (Acrustox). The following soil quality attributes were measured: bulk density, mechanical resistance to penetration, water infiltration rate, organic matter content, cation exchange capacity, […]

The effect of physical, chemical and biological soil attributes on the stability of wet aggregates of two Oxisols cultivated with annual crops under no tillage for over four years was evaluated. Soils samples were collected in the 0-10 cm layer of two areas in a 100 m square grid marked with a DGPS. One of the areas is located in Campos Novos Paulista county, SP, Brazil (22 º36 ‘ 11 ” latitude and 50 º00 ‘ 09 ” longitude) on […]
