13. Does Crop-Livestock-Forest Systems Contribute to Soil Quality in Brazilian Savannas?
ABSTRACT In this paper we discuss the impact on conversion degraded pasture areas into an integrated crop, livestock and forest system (ICLFS). We collected 30 soil samples at 0-0.1 m depth in five agroforestry systems, degraded pasture and native areas along Brazilian Cerrado biome. We analyzed the influence of chemical variables on microbial biomass carbon

15. Environmental and Ecosystem Services, Tree Diversity and Knowledge of Family Farmers
ABSTRACT The objective of this work is to identify environmental and ecosystem services provided by trees from the perception of family farmers in the Serra dos Tapes, southern Rio Grande do Sul, Brazil, addressing the relevance of species for ecosystem sustainability of family farming. Environmental and ecosystem services offered by the tree flora of semi-

16. Dynamics of solar radiation and soybean yield in agroforestry systems
Abstract Soybean (Glycine max L.) monocropping have had a great socio-economic and environmental impact on the world and agroforestry systems has been considered an alternative for more sustainable production. The aim of this study was to evaluate the effect of different arrangements of agroforestry systems of the species E. urophylla x E. grandis and P. dub

17. Growth of tree species and sugarcane production in agroforestry systems
Abstract The appropriate choice of tree species and planting arrangement for use in agroforestry systems is very important in order to maximize productivity and sustainability. The aim of this study was to evaluate the growth of five tree species and its effect on sugarcane yields in different planting arrays in agroforestry systems. The study was conducted

18. Inceptisol Physicochemical Attributes in the Caatinga Biome Agroforestry Systems
ABSTRACT We evaluated two areas of sustainable management within the Caatinga and one area of conventional agricultural cultivation to compare their physicochemical attributes with those of native forest. The management strategies were as follows: (1) thinning of savanna; (2) thinning of strips; (3) conventional tillage with plowing and harrowing; and (4) n

19. Contamination and Soil Biological Properties in the Serra Pelada Mine - Amazonia, Brazil
ABSTRACT Discovered in 1980 and unleashed an utter gold rush of the modern era, Serra Pelada was the largest open-air mine in Brazil. About 80,000 gold prospectors worked there until 1984, when the gold pits were flooded. The environmental impact caused by mining inflicted irreversible damage to the ecosystem, with the formation of a large lake and piles of

20. Evaluation of Meat and Egg Traits of Beijing-you Chickens Rotationally Grazing on Chicory Pasture in a Chestnut Forest
ABSTRACT Barn and cage-fed chickens have presented several problems, such as high rates of infectious disease and consequent antibiotic abuse, poorer chicken health and welfare, and often poorer meat and egg quality compared with free-range chickens. The poultry agroforestry system is becoming increasingly popular in many poultry farms nowadays. In this stud

21. Floristic evolution in an agroforestry system cultivation in Southern Brazil
RESUMO A bracatinga (Mimosa scabrella Bentham.) é uma importante espécie arbórea pioneira da Floresta Ombrófila Mista no Brasil e é amplamente utilizada como fonte de energia. Em sistemas tradicionais agroflorestais, a regeneração é induzida pelo fogo, em seguida povoamentos puros e densos conhecidos como bracatingais são formados. No primeiro ano,

22. Agroforestry systems, nutrients in litter and microbial activity in soils cultivated with coffee at high altitude
Agroforestry systems are an alternative option for sustainable production management. These systems contain trees that absorb nutrients from deeper layers of the soil and leaf litter that help improve the soil quality of the rough terrain in high altitude areas, which are areas extremely susceptible to environmental degradation. The aim of this study was to
