1. Leaching of Heavy Metals in Soils Conditioned with Biosolids from Sewage Sludge
ABSTRACT A promising use of biosolids is as organic fertilizer in agricultural and forestry activities. However, its composition might contain several pollutants, especially heavy metals, which may result in an increase in the concentrations of these elements in the soil and the risk of groundwater contamination. This study aimed to determine the leaching le

5. Tree Growth and Nutrient Dynamics in Pine Plantations in Southern Brazil
ABSTRACT For the development of nutrient budget models to recommend lime and fertilizers for agricultural and forestry crops, curves of plant growth and nutrient accumulation are required. Information about how nutrients are partitioned between the different plant organs is also necessary, but still scarce for pine in Brazil. This study evaluated the growth,

6. Identifying forest ecosystem regions for agricultural use and conservation
ABSTRACT Balancing agricultural needs with the need to protect biodiverse environments presents a challenge to forestry management. An imbalance in resource production and ecosystem regulation often leads to degradation or deforestation such as when excessive cultivation damages forest biodiversity. Lack of information on geospatial biodiversity may hamper f

7. Influencia del cambio climático en los escenarios del futuro sobre plantaciones de Eucalipto
The genus Eucalyptus presents a large commercial potential and it is the arboreal species most planted in Brazil. Perspectives of climate change in the future projections of the IPCC (Intergovernmental Panel on Climate Change) indicate that productivity losses may occur in diverse agricultural and forestry crops. The objective of this study was to determine
