Infiltração de água no solo em um latossolo vermelho da região sudoeste dos cerrados com diferentes sistemas de uso e manejo

Abstract: (6) RESUMO Na região do Cerrado, as atividades agrícolas têm provocado impactos negativos, principalmente, na qualidade do solo e da água. Tanto em sistemas de exploração agrícola ou de pecuária, com diferentes manejos, a degradação física do solo é uma das consequências da redução da produtividade. O objetivo deste trabalho foi verificar a infiltração de água no solo sob influência de diferentes sistemas de manejo em um Latossolo Vermelho distrófico na região dos Cerrados. Os tratamentos foram os seguintes si… Show more

“…The soil with native cerrado vegetation had little variation in I during the evaluation time and had higher average in relation to other use systems followed by, in descending order, the areas planted with eucalyptus, pasture and corn. For Bono et al (2012), removal of natural vegetation and the introduction, of either pasture or crops, leads to a consequent reduction of the basic water infiltration rate, confirming the findings of the present study.…”

“…In relation to the BIV obtained in the field, the soil that suffered less anthropogenic actions, that is, the soil treated with no tillage, returned better results, obtaining an infiltration rate 2.87 times greater than in the treatment with minimum tillage and 8.67 times greater than in the Conventional tillage, as can be seen in Table 1, similar results were evidenced in the works of Bono et al (2012) and Gonçalves and Moraes (2012), where it was evidenced an expressively better result in plantations with the reduced use of agricultural machinery. In relation to the mathematical adjustments, it can be observed that the model that best adjusted the BIV was the one of Horton, that in all the managements obtained the result equal to the one obtained in the field.…”

“…This means that water can infiltrate and move better within the soil profile, the characteristic curve for water retention improves and there is less resistance to root system penetration, as discussed in the works of Carvalho et al (2004) and Bono et al (2012).…”

“…Well-managed pasture, be it continuous pasture or integrated with crops, avoids physical degradation of the soil and protects against the impact of raindrops. It also prevents the soil surface structure from deteriorating and increases the infiltration of water into the soil; furthermore, the root system promotes improvements in soil structure (Salton et al, 2008;Bono et al, 2012).…”
