Avaliação da aptidão agrícola das terras como subsídio ao assentamento de famílias rurais, utilizando sistemas de informações geográficas
Rural settlements in Brazil were created in order to confront pressures and are characterized by the lack of planning prior to the diagnosis and implementation of the natural resources related to land suitability evaluation, distribution of classes such as topography, rivers system, vegetation, and support mechanisms.
Physical properties of dystrophic Red Latosol (Oxisol) under different agricultural uses
Obtaining information about soil properties under different agricultural uses to plan soil management is very important with a view to sustainability in the different agricultural systems. The aim of this study was to evaluate changes in certain indicators of the physical quality of a dystrophic Red Latosol (Oxisol) under different agricultural uses. The study was conducted in an agricultural area located in northern Paraná State.
Revegetação com plantas de cobertura em solos arenizados sob erosão eólica no Rio Grande do Sul
The degradation of soils with high sand content, in the southwest of the state of Rio Grande do Sul, is due to the vegetal cover withdrawal, forming sandy areas called "areais", which pose a risk to animal husbandry and the prairie ecosystem. A technique of revegetation with cover crops such as Avena strigosa Schieb. and Lupinus albescens H. et Arn., was developed to reduce the soil particle movement by eolic erosion.
Estoques de carbono e nitrogênio e frações orgânicas de Latossolo submetido a diferentes sistemas de uso e manejo
The advance of the agricultural frontier, characterized by the conversion of natural ecosystems into cultivated areas, was intensified in the last decades. Most of the practices used to manage soils cause changes in the soil quality and soil organic matter (SOM) dynamics. Studying the impact of different management systems is essential to choose the most adequate soil management practices.
