Introduction
I am a researcher at the Department of Soil and Irrigation of the Centro de Investigación y Tecnología Agroalimentaria de Aragón (CITA) in Zaragoza (Spain). My research interest focuses on assessing the effects of agricultural practices (irrigation, fertilization, soil management) on the performance of fruit orchards and vineyards, integrating the resulting knowledge on models that allow for taking informed decisions that, ultimately, lead to the sustainability of the agricultural systems.

Sustainable agriculture has drawn attention to the maintenance and enhancement of soil health. However, research on soil quality has been carried out mainly in field crops and, to a lesser extent, in mature orchards, neglecting the relevance of assessing the soil quality status in the first years of tree plantations. Therefore, the aim of this stud...

Clarification of the musts is carried out to remove particles that cause turbidity, oxidizable polyphenols, and eliminate excess of proteins. However, an excessive clarification of the musts can lead to the reduction of volatile compound concentrations and, as a consequence, modify the sensorial properties of the wines. Therefore, in this study, th...

The three-year study consisted of two trials conducted in parallel...
Article
The relation between water-use and intercepted solar radiation depends on many factors involved in vine canopy architecture and physiology. In addition, vine productivity is related to the efficiency with which the intercepted photosynthetically active radiation (IPAR) is used, which in turn depends mainly on water availability and transport. In he...
