Variabilidade espacial da retenção de água em dois solos tropicais.

Abstract

The purpose of this study was to identify the spatial variability of the soil moisture at any tensions for two tropical soils. Were taken undisturbed soils samples of “Terra Roxa Estruturada” (Rhodic Kanhapludalf) and “Podzólico Vermelho Escuro” (Kandiuldalfic Eutrudox). The soil moisture for two soils presents spatial dependence described by semivariograms with structure for each tension. The spatial structure is characteristics for each soil, expressing the differential action of the genesis process.
