Conteúdo:  Small farmers in the Bragantina (East-Amazonia, Brazil) traditionally apply a rotation of 2 years cultivation and 4?10 years forest fallow. More recently introduced pepper plantations fell fallow after fungus hazards. We studied the floristic composition of this young secondary vegetation by means of 92 vegetation relevés in 58 plots of forest fallow and 34 plots of pepper fallow with sizes ranging from 40 to 300 m2. The age of the fallow vegetation ranged from 4 months to 10 years. We found 673 species belonging to 97 families. The list of plant species presented in the Appendix totals 827 species, including species collected in additional field surveys. The species are registered with scientific and local names as well as growth forms. The families with the largest numbers of species were Myrtaceae (34 species), Leguminosae (87), Sapindaceae (17), which contain mainly trees and shrubs, and Bignoniaceae (29), Connaraceae (12), Smilacaceae (22) with mainly vines, the forb dominated families Asteraceae (25), Euphorbiaceae (21), Rubiaceae (20), and Cyperaceae (16) and Poaceae (35). A comparison with local and regional inventories shows similarities to fallow vegetations and secondary forests, and floristic distance to primary forests

Título:  Earthworms as soil health indicators in no-tillage agroecosystems.

Conteúdo:  No-tillage (NT) and no-tillage systems (NTS) are widely used conservation agriculture practices in Brazil, and in the state of Paran´a, nearly 80% of annual crops are cultivated using these methods. Compared with NT, NTS sites permanently include: minimum soil disturbance, soil cover (straw and living vegetation) and crop rotation and diversification with cover crops. These practices often increase earthworm populations, that can be used to indicate soil health. Herein, we review soil health classification of NT sites, and the species found in Paran´a state. We compiled information from 130 sites with NT or NTS, located in 29 counties, of which 93 had biomass and 91 had species richness data, aiming to compare NT with NTS sites, and the effect of the age of these practices on earthworm populations. Overall, 29 earthworm species were recorded, of which 17 were native, including many new to science. Mean abundance and biomass in NT + NTS were 104 ind m 2 and 2.5 g m 2, respectively, and richness 2.5 species per site. Abundance was significantly higher in NT than NTS in the initial phase of adoption, and both abundance and biomass decreased with increasing age of NT. Earthworm abundance and species richness were positively correlated with clayey soils and phosphorus content, while higher biomass was asso- ciated with soil carbon content and pH. A new classification system was proposed, with the categories poor (<50 ind. m 2, 1 species), moderate (≥50 to <100 ind m 2, 2 species)... Mostrar Tudo
