The objective of this study was to analyse the effect of planting density on soil profile moisture in a clonal Eucalyptus plantation. Soil moisture was observed every 15 days at 25 points distributed throughout the eucalyptus stand between November 2013 and October 2015 to characterize the moisture according to the following three types of spacings: 3 x 2, 3 x 3, and 3 x 5 m. At each point, the 0 - 10, 10 - 20, 20 - 30, 30 – 40, and 60 - 100 cm layers were evaluated using a Profile Probe PR2 model. Soil moisture showed high spatial variability in the 0 - 10 cm layer, whereas from 30 to 100 cm deep, the moisture tended to become more homogeneous throughout the area. The dry periods presented greater temporal soil moisture stability when compared to the rainy seasons. The 3 x 2 m spacing has greater temporal soil moisture stability when compared to the others, while the 3 x 3 m spacing presented greater temporal variability. 2017 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303050908015 https://www.redalyc.org/journal/3030/303050908015/ https://www.redalyc.org/journal/3030/303050908015/html/ https://www.redalyc.org/journal/3030/303050908015/303050908015.epub https://www.redalyc.org/journal/3030/303050908015/movil en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
