hourly variability of soil temperature profile in an orchard of mango trees (mangifera indica l.) in the location of cuiarana, salinopolis – pa

Abstract

The soil temperature is one of the most important elements in the characterization of a microclimate. The aim of this work was to analyze the temperature profile in the soil, on surfaces with vegetated and non-vegetated soil, checking the average hourly variation of soil temperature at different depths and comparing the soil temperature profiles. The hourly data of soil temperature were measured and collected during the period of 23 at 25 June of 2015, in the experimental site Modesto Rodrigues, in the locality of Cuiarana, Salinopolis-PA. The soil temperature increases from 6h to approximately 14h, and decreases from that time. The highest temperatures occur in non-vegetated soil and the lower temperatures in the vegetated soil, due to the presence of higher humidity in vegetated soil. In the analysis of results, the conclusion is that soil temperature was directly related to solar radiation exposure time, being this kind of information, essential in understanding agro-meteorological and micrometeorological studies.
