MATERIALS AND METHODS
The s udy was ca ied ou on a p ocessing oma o a m in Tala e a la Real (Badajoz,
Spain), di iding he plo in o h ee managemen zones:
The soil was cha ac e ised using Dualem-1S senso s (appa en elec ical conduc i i y)
and mois u e senso s (Te os 10), he mal senso s and wa e me e s we e ins alled.
I iDesK in eg a ed his in o ma ion wi h me eo ological da a and a seasonal i iga ion
plan, applying RDI s a egies in he ipening phase. The amoun o wa e applied c op
