Rising temperatures advance key stages of plant development, such as flowering, increasing crop vulnerability to late frost events and generating significant production losses.<\/p>\n<h3 data-start=\"622\" data-end=\"654\">Objective of the pilot trial<\/h3>\n<p data-start=\"656\" data-end=\"997\">This pilot trial aims to assess the impact of different frost mitigation techniques in apple orchards and vineyards, analysing their effect on air temperature and crop surface temperature, as well as on the energy balance of the soil\u2013plant\u2013atmosphere system. To this end, advanced sensor technologies and thermal remote sensing are employed.<\/p>\n<h3 data-start=\"999\" data-end=\"1025\">Activities carried out<\/h3>\n<p data-start=\"1027\" data-end=\"1068\">The main activities of the pilot include:<\/p>\n<ul data-start=\"1070\" data-end=\"1387\">\n<li data-start=\"1070\" data-end=\"1159\">\n<p data-start=\"1072\" data-end=\"1159\">installation and monitoring of sensors for continuous tracking of the energy balance,<\/p>\n<\/li>\n<li data-start=\"1160\" data-end=\"1243\">\n<p data-start=\"1162\" data-end=\"1243\">development and implementation of the Bowen-ratio model for heat flux analysis,<\/p>\n<\/li>\n<li data-start=\"1244\" data-end=\"1291\">\n<p data-start=\"1246\" data-end=\"1291\">analysis of winter and spring frost events,<\/p>\n<\/li>\n<li data-start=\"1292\" data-end=\"1387\">\n<p data-start=\"1294\" data-end=\"1387\">acquisition of high-resolution thermal images through drone flights during real frost events.<\/p>\n<\/li>\n<\/ul>\n<h3 data-start=\"1389\" data-end=\"1403\">Pilot site<\/h3>\n<p data-start=\"1405\" data-end=\"1687\">The trial is carried out at two locations in the province of Lleida: the IRTA experimental station in Mollerussa, in an apple orchard under netting, and a vineyard belonging to Bodegas Raimat, Tempranillo variety, with different soil management treatments and irrigation strategies.<\/p>\n<h3 data-start=\"1689\" data-end=\"1712\">Preliminary results<\/h3>\n<p data-start=\"1714\" data-end=\"2076\">During the winter of 2025, frost events were recorded with temperatures reaching up to \u22124 \u00b0C. The thermal flights conducted made it possible to identify significant temperature differences between areas with and without ground cover, as well as in areas with punctual application of heat sources, providing key information to improve frost mitigation strategies.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Pilot trial of the An-Gel Sudoe project aimed at assessing spring frost mitigation techniques in apple orchards and vineyards.
