14. ALTERAÇÕES FÍSICAS E QUÍMICAS DE UM CAMBISSOLO HÚMICO EM POVOAMENTOS DE Pinus taeda L. COM DIFERENTES ROTAÇÕES / PHYSICAL AND CHEMICAL CHANGES OF A Haplumbrept IN STANDS OF Pinus taeda L. WITH DIFFERENT ROTATIONS
Starting from the assumption that changes in land use can provide changes in physical and chemical properties, influencing its quality, the study aimed to verify whether the introduction of Pinus taeda L., on soil under native grassland conditions, can degrade physical and chemical quality of Haplumbrept soil in different rotations. The study was conducted i

15. Caracterização da fertilidade do solo, distribuição do sistema radicular e índice de qualidade do solo no Ecossistema Restinga do Litoral Paulista
A Restinga é um conjunto de comunidades vegetais em mosaico, determinadas pelas características de seus substratos resultantes de processos deposicionais e idades. De todos os ecossistemas associados à Mata Atlântica, a restinga é a mais frágil e susceptível às perturbações antrópicas. Neste complexo mosaico encontram-se as fitofisionomias de flor

17. CORRECTION OF THE ACIDITY OF THE SOIL IN SUBSURFACE IN A OXISSOL OF FRANC-SANDY TEXTURE UNDER NO TILLAGE / CORREÇÃO DA ACIDEZ DO SOLO EM SUBSUPERFÍCIE EM UM LATOSSOLO DE TEXTURA FRANCO-ARENOSA SOB PLANTIO DIRETO
In tropical and subtropical areas, especially, where there is the dry period occurrence, the acidity subsurface (below the 10 cm) it has been pointed as one of the limitation causes to the growth of roots and the agricultural productivity. In the state of Rio Grande do Sul, in the last years, reports exist that areas under no tillage that don t present excha

18. Fertirrigation with cattle wastewater in Tifton 85 grass and black oat: effects on soil and plants / Fertirrigação de capim-Tifton 85 e aveia preta com águas residuárias de bovinocultura: efeitos no solo e nas plantas
This study was conducted to evaluate the effects from the application of cattle wastewater (ARB) upon both physical and chemical properties of an Eutrophic Red Argisol and on the physiologic, nutritional and yield characteristics of the 85-Tifton grass (Cynodon spp.) and the black oat plant (Avena strigosa Schreb). The experiment was carried out in 20 draina

19. ESTUDO QUÍMICO DO SOLO E LIXIVIADO DO ATERRO CONTROLADO DO BOTUQUARA
Currently, the production and storage of solid residues have generated a discuss range about linked aspects to the disease propagation and environment damage, mainly due to the formation of leach and its infiltration, could cause earth contamination, flow and ground water. The final disposition place of trash at Ponta Grossa city started out in 1969, in an a

20. Efeito da aplicação de percolado de resíduo sólido urbano em solo cultivado com capim-tifton 85 / Effect from the application of the municipal refuse percolate on the soil cropped with Tifton-85 grass
The effects from the application of different percolate rates of municipal solid waste (RSU) on the chemical characteristics of the soil, productivity and mineral composition of the tifton- 85 grass (Cynodon spp) were evaluated. The experiment was conducted in the Experimental Area for Treatment of Residues pertaining to the Department of Agricultural Engine

21. Influence of the phreatic aquifer in the nutrient dynamics (nitrogen and phosphorus) in lakes of different hydrodynamic characteristics / Influência do aqüífero freático na dinâmica de nutrientes (nitrogênio e fósforo) em lagoas com diferentes características hidrodinâmicas
The discharge zone of Paranapanema river at Jurumirim reservoir is an area of decreased current velocity associated to a great number of aquatic environments with different hydrodynamic characteristics. To evaluate the influence of the superficial phreatic aquifer in the nutrient dynamics (nitrogen and phosphorus and main cations), three floodplain lakes wit

24. Caracterização e classificação de solos da Ilha de Fernando de Noronha (PE)
In the main island of Fernando de Noronha Archipelago, the dry tropical climate with oceanic influence and the recent parent material of volcanic origin, are responsible for the small weathering of soils with high scientific importance for the development of the Brazilian System of Soil Classification (SiBCS). Seven representative soil profiles, involving tw
