Fertirrigation is being tested in cork oak plantations to accelerate tree growth up to the production stage. To assess the impact of wet bulb location on tree development, six trees (three subjected to subsurface drip irrigation and three controls) were fully excavated at a sandy soil site, along with a seventh tree subjected to surface drip irrigation at a sandy loam soil site. The aerial parts of the trees were digitized using a Polhemus Fastrak magnetic digitizer and segmented into orders starting from the main trunk. Roots with diameters greater than 0.5 cm were digitized during excavation and segmented by size and order from the root collar. For each segment, length, orientation, and spatial location were calculated. General linear models were then applied to compare total root length across orientation and quadrant classes. Crown architecture was influenced by factors such as light competition. Irrigation treatments did not significantly affect root architecture when wet bulb formation was constrained. However, tree no. 7 had 50% of its total root length located within the wet bulb quadrant. These findings suggest that differences in soil type and irrigation method influence wet bulb formation, potentially reducing the impact of fertirrigation on root architecture. Strategies to minimize tree dependence on wet bulb zones are crucial for enabling future irrigation suppression.<\/jats:p>","DOI":"10.3390\/agronomy15020373","type":"journal-article","created":{"date-parts":[[2025,1,31]],"date-time":"2025-01-31T04:05:47Z","timestamp":1738296347000},"page":"373","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Analysis of Crown and Root Orientation of Quercus suber in Relation to the Irrigation System Using a Magnetic Digitizer"],"prefix":"10.3390","volume":"15","author":[{"given":"Krist\u00fdna","family":"\u0160leglov\u00e1","sequence":"first","affiliation":[{"name":"Faculty of Forestry and Wood Sciences, Czech University of Life Sciences Prague, Kam\u00fdck\u00e1 129, 165 00 Prague, Czech Republic"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5156-172X","authenticated-orcid":false,"given":"Constan\u00e7a","family":"Camilo-Alves","sequence":"additional","affiliation":[{"name":"MED\u2014Mediterranean Institute for Agriculture, Environment and Development & CHANGE-Global Change and Sustainability Institute, 7000-011 \u00c9vora, Portugal"},{"name":"Institute for Advanced Studies and Research, University of Evora, P\u00f3lo da Mitra, Ap. 94, 7006-554 \u00c9vora, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6049-807X","authenticated-orcid":false,"given":"Ana","family":"Poeiras","sequence":"additional","affiliation":[{"name":"MED\u2014Mediterranean Institute for Agriculture, Environment and Development & CHANGE-Global Change and Sustainability Institute, 7000-011 \u00c9vora, Portugal"},{"name":"Institute for Advanced Studies and Research, University of Evora, P\u00f3lo da Mitra, Ap. 94, 7006-554 \u00c9vora, Portugal"}]},{"given":"Jo\u00e3o","family":"Ribeiro","sequence":"additional","affiliation":[{"name":"ICT\u2014Institute of Earth Sciences, 7000-671 \u00c9vora, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6884-2808","authenticated-orcid":false,"given":"Nuno de Almeida","family":"Ribeiro","sequence":"additional","affiliation":[{"name":"ICT\u2014Institute of Earth Sciences, 7000-671 \u00c9vora, Portugal"},{"name":"Department of Plant Science, School of Science and Technology, University of Evora, P\u00f3lo da Mitra, Ap. 94, 7006-554 \u00c9vora, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6637-8661","authenticated-orcid":false,"given":"Peter","family":"Surov\u00fd","sequence":"additional","affiliation":[{"name":"Faculty of Forestry and Wood Sciences, Czech University of Life Sciences Prague, Kam\u00fdck\u00e1 129, 165 00 Prague, Czech Republic"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"40","DOI":"10.1002\/fee.2588","article-title":"Tree Crown Economics","volume":"21","author":"McNeil","year":"2023","journal-title":"Front.
