OBJECTIVE
To evaluate the efficacy of ILSA biostimulants and nutritional specialities on improving water management in drought years, such as that of 2021 in the Siena area.

RESULTS ACHIEVED
In particular, fertigation applications with IlsaPolicos allowed the plants to overcome water stress at the crucial time (July-August) while maintaining good turgidity of the leaf tissues. This also made it possible not to anticipate the harvest too much (as in the 2017 vintage), so that the harvested grapes had a good sugar content (on average 22 degrees Brix) and a good level of acidity, freshness and aromas.
