1. Temporal Variation of Soil Physical Quality under Conventional and No-Till Systems
ABSTRACT: Determination of soil physical quality (SPQ) is very important because it is related to many important soil processes. However, it is not clear which indicators should be considered in this evaluation, and information about temporal variation of SPQ under different soil tillage systems is scarce. The aim of this study was to determine the effects o

2. Physical Properties of Soil Structures Identified by the Profil Cultural under Two Soil Management Systems
ABSTRACT Soil structure plays an important role in water retention, infiltration capacity, porosity, and penetration resistance. The aim of this study was to evaluate the unsaturated hydraulic conductivity and physical properties of Oxisol soils (bulk density and macro-, micro-, and total porosity) in the structures identified using the profil cultural metho

3. Soil Physical Quality and Soybean Yield as Affected by Chiseling and Subsoiling of a No-Till Soil
ABSTRACT The concept of soil physical quality (SPQ) is currently under discussion, and an agreement about which soil physical properties should be included in the SPQ characterization has not been reached. The objectives of this study were to evaluate the ability of SPQ indicators based on static and dynamic soil properties to assess the effects of two loose

4. Condutividade hidráulica não saturada de um solo arenoso: aplicação do infiltrômetro de disco / Unsaturated hydraulic conductivity of a sandy soil using the disk infiltrometer
A função condutividade hidráulica é um dos parâmetros essenciais para o estudo do fluxo em solos não saturados, permitindo abordar, dentre outros, o avanço da frente de umedecimento e questões como a irrigação e drenagem de solos. Para determinar a condutividade hidráulica não saturada de um solo típico da região Centro-Oeste do Estado de São

5. Infiltracao da agua num latossolo roxo.
O experimento foi realizado em um latossolo roxo distrofico, e os tratamentos utilizados foram o metodo do infiltrometro de anel e quatro combinacoes diferentes de intensidade e duracao da precipitacao obtidas com o infiltrometro de aspersao tipo simulador de chuvas. Em cada parcela experimental foram realizadas quatro sucessoes de aplicacao de agua em dias

6. Bulbo infiltrômetro.
Na irrigação por gotejamento, recomenda-se que a percentagem de área molhada seja obtida em base ao bulbo molhado produzido por gotejadores em condições de campo. Entretanto, muitos sistemas são dimensionados utilizando-se dados tabelados devido a inexistência de equipamentos apropriados. Diante disto, desenvolveu-se um bulbo infiltrômetro que possib

7. Velocidade de infiltração da água em um latossolo amarelo submetido a diferentes sistemas de manejo. / Water infiltration speed rate in yellow latossoil undergone different soil management systems.
Water and soil are key factors in the definition of the appropriate exploration of an agricultural area. Infiltration is a dynamic process by means of which water enters the soil, both in the descending vertical as well as in horizontal direction. The knowledge of the infiltration rate in the soil is of paramount importance in order to define the conservatio

8. Investigação dos processos hidrossedimentológicos em parcela experimental no semi-árido potiguar
In northeastern semiarid, seasonality on precipitation temporal distribution, high intensity storm events and inadequate management of native vegetation can promote soil erosion. Vegetation removal causes soil surface exposure, reduces soil water storage capacity and can be the source degradation processes. In this context, this approach aims to analyze wate

9. ESTIMATING SOIL WATER INFILTRATION BASED ON PEDOFUNCTIONS / ESTIMATIVA DA INFILTRAÇÃO DE ÁGUA NO SOLO A PARTIR DE PEDOFUNÇÕES
Knowledge on soil water infiltration is essential for the solution of problems concerning irrigation and drainage areas and those related to water and soil conservation research. In that regard, the aim of this paper was to model water infiltration rate and hydraulic conductivity in saturated soil by means of pedotransfer functions for soils of various physi
