Sulfur is important for yield, as you can see in studies in Italy.
Trials in Germany show that foliar applications can be more effective than soil applied fertilizer.
Sulfur also increases fruit total soluble solids content, as shown in studies in Italy.
Uptake of sulfur is around 1.2lb/t of fruit. It is required throughout the season, and should be timed similar to nitrogen supplies.
