In the southeast of France it has not rained for almost 50 days. This could soon become a major problem for the region's vineyards: Experts in agricultural meteorology are advising winegrowers to irrigate now in order to avoid disrupting the vine cycle and reducing yields. Although rain has been announced for the coming days, the amount announced is clearly too little. "It will not be enough to replenish the water table before summer," said agro-climatologist Serge Zaka.
His colleague Amélia Caffarra points out that the precipitation deficit in the wine-growing region is currently up to 50 mm. Studies have shown that less precipitation in winter can delay budbreak and reduce yields by up to 40 percent. The problem is also known as "delayed spring growth". "It is often caused by lack of soil moisture. This leads to wilting buds, delayed growth and, in the worst cases, to coulure and breakage of the young fruits," explains Amélia Caffarra.
