1. PROPRIEDADES FÍSICAS DE UMA TOPOSSEQUÊNCIA ARGISSOLO-GLEISSOLO / PHYSICAL PROPERTIES OF A TOPOSEQUENCE GLEY-PODZOLIC
Os solos da Depressão Central Gaúcha são constituidos porareia, silte e argila. A região tem cotas entre 40 à 100 m, nas mais baixas (várzea) predominam os Gleissolos e nas coxilhas predominam os Argissolos. O objetivo deste trabalho foi avaliar o comportamento compressivo (capacidade de suporte e susceptibilidade a compactação) do solo, e a influên

2. Spatial Variability of Some Soil Physical Properties in Three Soils of Sao Paulo, Brazil.
Volumetric core samples and loose soil samples were collected at 1 m interval in 10 m long transects, on three major soil groups in São Paulo, Brazil. The soil cores were used for soil desorption curves and the bulk density, and the loose soil was used for particle size analysis. The parameters obtained from the soil water retention model, bulk density and

3. Estimativa da velocidade de infiltracao basica do solo.
Objetivando estimar a velocidade de infiltracao basica (VIB), avaliou-se a associacao desta com outras propriedades fisicas das camadas superficial e subsuperficial de um Latossolo Roxo e um Podzolico Vermelho-Amarelo, ambos ocorrentes no campus da Universidade Federal de Lavras. Para tanto, delineou-se um plano amostral consistindo de uma rede cujas malhas

4. Absorcao de metais pesados pelo azevem (Lolium multiflorum) em dois solos do estado do Rio Grande do Sul.
Com o objetivo de avaliar a absorcao de metais pesados para as plantas, foi instalado um experimento em vasos, ao ar livre, com dois solos podzolicos vermelho-amarelos do Rio Grande do Sul, nos quais foi plantado o azevem. Os metais pesados Ni, Pb, Cd, Zn e Cu, em dois niveis, foram adicionados aos solos no lodo procedente do sistema Integrado de Tratamento

5. PROPRIEDADES FÍSICAS E QUÍMICAS DE UM SOLO ARENOSO SOB O CULTIVO DE Eucalypus spp. / PHYSICAL AND CHEMICAL PROPERTIES OF SANDY SOIL UNDER CULTIVATION OF Eucalypus spp.
The study was carried out to evaluate the changes in the physical and chemical properties of a sandy soil after afforestation of an Eucalyptus forest planted in different spacing resulting in several plant population. The initial plant growth was also monitored. It was accomplished an experiment planted with Eucalyptus dunnii Maiden planted on Alfisol (Red Y

6. Caracterização hidrológica dos solos da bacia experimental do Ribeirão Concórdia, Lontras/SC
The knowledge of the physical and hydraulic soil properties is highly important to both use and appropriate management of the soil, as well as the understanding of the dynamic process of water and solutes movement. This work has the finality to generate knowledge about the hydrological characteristics of the soil of the experimental Basin of Ribeirão Concó

7. DiagnÃstico do uso e ocupaÃÃo do solo na bacia hidrogrÃfica do Rio SÃo JosÃ, Cascavel â PR.
The use of soil is understood as a space that is being occupied by man, developing a set of activities of production and reproduction of a society, involving both urban and agricultural areas. Due to the economic development of the last few years, this subject has been studied more and more with a common concern: the quality of water. The objective of this p

8. "Interações entre modelado e solo no transecto Espraiado, São Pedro, SP" / Soil-landform relationships in the Espraiado Transect, São Pedro, São Paulo.
The objective of this research is to identify macro and micromorphological features (field and and optical microscopic scale, respectively) and analitycal evidences (physical and chemical parameters), indicative of translocations, losses and acumulations mechanisms inside the soils, that probably leads to changes in the form of a transect, localized in São

9. Caracterização fisica dos solos de uma microbacia degradada em Vera Cruz, SP
The knowledgement of soil physical properties in a catchment basin, in special at places which show signs of erosion and degradation, represent the flfst step for a successful conservation planning as well as to provide additional information for the application of mathematical models that determine the soil erosion potential. This study was carried out to c

11. Metodos de determinação do selamento superficial na irrigação por aspersão
Soil surface sealing is characterized as an organized fine particle layer with high density which can reduce the soil infiltration rate. It is caused by the impact of rainfall or irrigation water droplets. The occurrence of the soil surface sealing can result in negative effects, such as, reduction of soil water intake and soil-water holding capacity, inerca

12. Floristica, fitossociologia e caracterização sucessional em uma floresta estacional semidecidual : Mata da Virginia,Matão, SP
This work was developed in the mata da Virgínia, with 2.072,64ha, being one of the biggest remnants of semidecidual stational forest of the São Paulo state, situated in a farmer named Cambuhy between the cities of Matão and Tabatinga ( 48°. 30 W e 21°.35 5). Different physiognomy were identified in the forest from the analysis of aerial photos and some
