ANÁLISE DO COMPORTAMENTO DE MODELOS PARA AJUSTE DA VELOCIDADE DE INFILTRAÇÃO EM DIFERENTES USOS DE SOLO - DOI: 10.7127/rbai.v12n400971

With the objective of analyze the behavior of the mathematical models of Horton (1940), Kostiakov (1932), Kostiakov-Lewis (1945), and Phillip (1957), the  tests of water infiltration were realized in an experimental area of the Federal University of Sergipe (UFS) in a YELLOW RED ARGISSOL in different managements and using different antecedent crops. Soil use management consisted of conventional cultivation, minimum tillage, no-tillage and cultivation of antecedent crops in succession with the Biomatrix BM 3061 maize variety. The antecedent crops were sunflower ( Helianthus annuus ), millet ( Pennisetum glaucum (L.) R. BR.), guandu (Cajanus cajan ) and crotalaria ( Crotalaria juncea ). In an overview the mathematical model that on average obtained better results was Philip's. However, within the limitations of each model, all generated statistically equivalent results, with the exception of Kostiakov-Lewis.
