25. 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

26. GROWTH, YIELD AND ECONOMIC ANALYSIS OF AN EUCALYPT-SOYBEAN CONSORTIUM: EFFECT OF THE DISTANCE BETWEEN TREES WITHIN THE ROW1
RESUMO Os sistemas agroflorestais (SAF) devem beneficiar todos os componentes do consórcio. O objetivo deste trabalho foi avaliar o efeito da distância entre plantas na linha de plantio sobre o crescimento e a produção do componente arbóreo e da cultura agrícola e, sobre a viabilidade econômica do consórcio. Para isso plantou-se clone de eucalipto no

28. 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-

29. 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

30. 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

31. 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

32. Soil Microbial Attributes Under Agroforestry Systems in the Cerrado of Minas Gerais
ABSTRACT The aim of this study was to evaluate the soil microbiological attributes of two Agroforestry Systems (AFS) in the city of Grão Mogol-MG considering two soil classes (Udox and Aqualf). Three composite samples were collected from the 0-5 cm soil depth layer. Each sample was subsequently divided into five replications to evaluate the carbon of soil

33. 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

34. Vegetation structure, carbon sequestration potential and species conservation in four agroforestry systems in Cameroon (Tropical Africa)
ABSTRACT As the rate of forest degradation continues to rise, agroforestry may serve as a way of conserving species and carbon sinks. The aim of this study was to assess agrobiodiversity and carbon sequestration potential in agrosystems in Cameroon. Three age groups of agrosystems were studied. Data were collected in 100x50 m2 quadrates. Density ranged from

35. Symbiotic effectiveness of Bradyrhizobium ingae in promoting growth of Inga edulis Mart. seedlings
ABSTRACT Inga edulis Mart. is a leguminous tree adapted to acidic and low-fertility soils that establishes symbioses with nitrogen (N)-fixing bacteria. The identification of effective bacteria in biological N fixation may bolster the use of I. edulis in degraded or modified areas and agroforestry systems. Therefore, the aims of this study were evaluation of

36. Do gender and age influence agroforestry farmers' knowledge of tree species uses in an area of the Atlantic Forest, Brazil?
ABSTRACT This study aimed to explore the extent of knowledge of tree species and their uses by agroforestry farmers in the Vale do Ribeira, Brazil, to verify whether gender and age are related to species knowledge in different use categories. The study was conducted using semi-structured interviews, guided tours, direct observation and collection and identif
