Resumo: |
Studies related to water dynamics, without soil to make semi-arid, are important because they are areas with great water scarcity, where a infiltration of water does not only influence directly the soil dynamics, crop yield and optimization of water use. The general objective of the research was to evaluate the basic infiltration capacity of the Fluovian Neossolo and the Hapless Cambisol without semiarid Pernambuco, in rainy and dry periods, using the Horton and Kostiakov equation models, the infiltrator method with concentric double ring rings. The physical characteristics of the studied soils were classified with both sandy loam texture, with terms in the granulometric composition. The initial infiltration capacity was high with a value of 39.75 cm.h-1 for the Cambisols, compared with a Neosol for the dry period of 23.44 cm.h-1, as well as for the Neosol 24.09 cm. H-1 and Cambissolo 24.84 cm.h-1 in the rainy season. The infiltration capacity of the Hapol Cambisol showed to be superior to the other treatments, being able to be related to a structural development of this soil in comparison to the Flossic Neosol. Both the Kostiakov and Horton equations can be used to estimate the potential rate of soil infiltration in situ without semiarid. |
