“…These results corroborate those found by Zwirtes et al (2011), that working on a typic ferric aluminum Red Latosol observed that the soil of the native forest has a higher infiltration rate (IR) compared to that suffered human action and that the infiltration rate is lower in soil that has grazing bovine. Just as for SIR, the IS also suffers the same influence over the structural changes of the soil, due to the different types of management systems adopted.…”

This study aimed to evaluate the water infiltration, hydraulic conductivity and hydraulic diffusivity in distroferric Red Latosol under different conditions of agricultural and livestock use. The different conditions of agricultural use and soil livestock are as follows: Cultivation of sugarcane, Annual crops, Crop-Livestock-Forest Integration Systems and Permanent Cerrado. Water infiltration in the soil was determined "in situ" by the method of cylinder infiltrometers and empirically through models Kostiakov, Kostiakov-Lewis and Horton. By means of infiltration of water in the soil, the hydraulic conductivity of the saturated soil and the hydraulic diffusivity of the soil were determined. In the evaluation, the following statistical indices were also used: Residual mass coefficient, adjustment coefficient and efficiency. Most hydraulic conductivity, hydraulic diffusivity and infiltration occurred in the then Cerrado area in descending order by the Sugarcane area, the Crop-livestock-forest integration systems and annual crops.Keywords: compaction; physical attributes; anthropic interference. VELOCIDADE DE INFILTRAÇÃO DE ÁGUA EM LATOSSOLO VERMELHO DISTROFÉRRICO SOB DIFERENTES SISTEMAS DE CULTIVO RESUMOObjetivou-se avaliar a infiltração de água, a condutividade hidráulica e a difusividade hidráulica em Latossolo Vermelho distroférrico sob diferentes condições de utilização agrícola e pecuária. As diferentes condições de utilização agrícola e pecuária do solo, foram as seguintes: Cultivo de cana-de-açúcar, Culturas anuais, Sistema Integração Lavoura, Pecuária e Floresta, e a Área de Cerrado permanente. A infiltração de água no solo foi determinada "in situ" através do método do infiltrômetro de anel e empiricamente por meio de modelos de Kostiakov, de KostiakovLewis e de Horton; a partir da infiltração de água no solo foi determinada a condutividade hidráulica do solo saturado e a difusividade hidráulica do solo. Na avaliação, foram também utilizados os seguintes índices estatísticos: coeficiente de massa residual, coeficiente de ajuste e eficiência. A maior condutividade hidráulica, difusividade hidráulica e infiltração ocorreu na área de cerrado seguida em ordem decrescente pela área de cana-de-açúcar, o sistema integração lavoura, pecuária e floresta e culturas anuais.Palavras-chave: compactação; atributos físicos; interferência antrópica.

“…Many other studies have also evidenced the higher infiltration rate in the minimum tillage system (Souza & Alves, 2003;Llanillo et al, 2006;Zwirtes et al, 2011). Different results were obtained by Netto & Fernandes (2005), in which the conventional tillage system showed higher T ie .…”

“…These authors attributed this result to the soil disturbance, which broke the sealed layer and increased the volume of macropores in the superficial layer, responsible for higher water flows in the beginning of the infiltration process. Franzluebbers (2002), Zwirtes et al (2011) and Gonçalves & Moraes (2012) observed higher T ie in the no-tillage system and explained that factors like the lack of soil disturbance and the presence of residues on the soil surface are determinant in the process of soil water infiltration, since the residues absorb the impact of raindrops and thus reduce superficial sealing. In addition, water infiltration is also influenced by the presence of biological channels, formed by the soil fauna and by the decomposition of roots.…”

A B S T R A C TThe management systems affect soil structure, causing changes in porosity that can influence soil water infiltration. In order to study the water infiltration rate in a Yellow Latosol under different tillage systems and different mathematical models, an experiment was conducted from October to December 2012, at the Center for Agricultural Sciences at the Federal University of Alagoas, using a randomized block design with five replicates, in a split-plot scheme. In the plots, the management systems were evaluated (conventional tillage, no-tillage and minimum tillage) and, in the sub-plots, the empirical mathematical models of Kostiakov, Kostiakov-Lewis and Horton, and the ring method. The method used to measure soil water infiltration rate was adapted from the classic double-ring infiltrometer method. The minimum tillage system provided better results compared with the others, with water infiltration rate of 167 mm h -1 , and the equation that best fitted the data of the ring infiltrometer was Kostiakov's, in the no-tillage system.

“…It can be explained by the low density of the soil at that time, which facilitates water infiltration along with the soil profile. Zwirtes et al (2011), in a study on soil water infiltration under different land, uses, stated that native forest areas had a higher water infiltration rate, contrary to what happens in agricultural or pasture areas, which modify the physical properties of the soil.…”

A determinação das taxas de infiltração de água no solo é de fundamental importância, pois além de determinar a recarga de aquíferos estima a vulnerabilidade a contaminação a qual o mesmo está sujeito. Com base nisso o presente trabalho tem por objetivo determinar o índice de infiltração de água no solo pelo método DRASTIC na bacia hidrográfica do rio Vacacaí-Mirim, no estado do Rio Grande do Sul. Para a determinação desses índices, seguiu-se a metodologia descrita por Oliveira e Ferreira (2002), onde as análises para os parâmetros físicos foram obtidos no laboratório de física do solo da Universidade Federal de Santa Maria, campus de Frederico Westphalen-RS. Os índices de facilidade a infiltração nos anos de 2010 e 2011 variaram de 10 (áreas pouco fissuradas) a 30 (áreas com altas perfurações). Com relação as áreas de infiltração máxima, no ano de 2010, 24 % da área da bacia apresentou tal condição, já para o ano de 2011, esse percentual caiu para 18,55 %. Com base nisso, a metodologia se mostra interessante para a determinação das taxas de infiltração de água na bacia hidrográfica do rio Vacacaí-Mirim. As áreas que mais se destacaram com as taxas de infiltração máxima localizam-se nas várzeas da bacia hidrográfica, onde predominam o cultivo de arroz, sendo assim é de fundamental importância a preservação de tais áreas com vista a manutenção da qualidade da água subterrânea no local.
