1. Extração de água do solo por plantas de soja: modelagem hidrofísica e empírica / Root water uptake by soybean plants: hydrophysical and empirical modeling
A extração de água do solo pelas plantas esta intimamente relacionada com a produtividade das culturas. O objetivo do presente estudo foi avaliar o desempenho das funções de redução de Jong Van Lier et al. (2008) e de Feddes, Kowalik e Zaradny (1978) na estimativa da extração de água por plantas de soja sob condições úmidas. A primeira e formali

2. Measuring statistical geometric properties of tomographic images of soils
Porous media modeling is relevant in several applications, such as agricultural engineering, where soil compaction analysis requires the estimation of soil transport properties. For example, the prediction of root growing patterns and their environmental impact is usually measured by analyzing soil fluid infiltration capacity and water retention. Recently, t

3. Partition of root water extraction between soil layers with distinct hydraulic properties / Partição da extração da água do solo por plantas entre camadas com propriedades hidráulicas distintas
Root water extraction is determined by soil hydraulic conductivity and water potential gradients, both dependent on soil water content. In this dissertation the experimental test of a root water extraction and partition model is described for a plant whose root system is divided over soil layers with distinct hydraulic properties. An experiment was conducted

4. Partição da extração da água do solo por plantas entre camadas com teores de água distintos / Partition of root water extraction between soil layers with distinct water contents
Water shortage is one of the most limiting factors for agricultural production. The understanding of factors that rule the extraction of soil water by plants and its distribution along the root system under contrasting hydraulic conditions is important for fine-tuning hydrological models which are a reference for crop growth models, meteorological models, am
