Resumo: Although soil moisture is defined by a single physical concept, its determination is not necessarily simple. Since such determination is necessary to soil-water management studies and practices, direct and indirect methods have been developed. Although the Time Domain Reflectometry (TDR) technique has been widely used in recent years, research has shown that prior calibration must be undertaken before the use of this technique. Scanty information exists for tropical soils. Research was undertaken on a Rhodic Kandiudalf, commonly found in the northeast region of the state of Paraná, Brazil. Present study detects the effects of probe characteristics and of soil moisture conditions at the moment of probe installation on the TDR measurements. Installation effects was much more important than probe characteristics. Soil water content during probe installation process affects TDR readings, probably affecting soil-probe contact

Dentre os métodos de determinação da umidade, destaca-se o TDR (Time Domain Reflectometry), por ser um método indireto, não destrutivo, rápido, supostamente pouco dependente dos fatores locais e bastante preciso. No entanto, existem indícios da influência de fatores externos sobre a sua operação, o que torna necessária a calibração local. Particularmente para solos tropicais, pouco se sabe a respeito da sua utilização. Este trabalho teve como objetivo avaliar um equipamento TDR para uso em um Nitossolo Vermelho Distroférrico, da região Noroeste do Estado do Paraná, avaliando a influência da instalação das sondas e de características de cada sonda, sobre as curvas de calibração. As diferenças entre sondas não influenciaram na calibração para este solo. Por outro lado, o contato solo - sonda, que varia conforme a instalação, pode influenciar na medida de umidade realizada com o uso desta técnicaUniversidade Estadual de Maringá2008-05-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/261510.4025/actasciagron.v23i0.2615Acta Scientiarum.
