1. Estimation of the Retention and Availability of Water in Soils of the State of Santa Catarina
ABSTRACT: Soil water retention and availability are important properties for agricultural production, which can be measured directly or estimated by pedotransfer functions. Some studies on this topic were carried out in Santa Catarina, Brazil. To improve the estimates, it is necessary to evaluate other properties, to analyze more soil types, as well as to us

2. PARÂMETROS FÍSICOS E HÍDRICOS RELACIONADOS COM O AVANÇO DA FRENTE DE MOLHAMENTO / PHYSICAL AND HYDRIC PARAMETERS RELATED TO THE SOIL WETTING FRONT ADVANCE
O presente estudo visou contribuir no âmbito metodológico, nas áreas da ciência do solo e da irrigação, notadamente a microirrigação (irrigação localizada), na obtenção in situ de parâmetros físicos e hídricos, em especial as funções hidrodinâmicas do Argissolo Vermelho Distrófico Arênico (PVd). Foi projetado um sistema multi-gotejador, c

3. CaracterizaÃÃo hidrodinÃmica de solos em campo e em laboratÃrio: anÃlise numÃrica e fractal / Hydrodynamic characterization of soils in the field and in laboratory: numerical and fractal analysis
The soil-water retention curve h(θ) and the hydraulic conductivity curve K(θ) were experimentally determined, from internal drainage and infiltration experiments, and estimated using the inverse method and pedo-transfer functions for a topsoil layer of two soils: a sandy soil contained in a lysimeter, and a Fluvent soil with loamy-sand texture, loc

4. Estimativa da capacidade de armazenamento de água no solo do Brasil. / Estimating of the soil moisture in Brazil
Soil moisture is a key variable in soil-atmosphere transfer processes. Soil moisture can be measured by direct and indirect techniques. Those methods are time consuming and impractical over large areas, such as Brazil. For this reason, soil moisture is generally estimated from the amount of water entering or draining from the soil profile by the water balanc
