Calcium materials were sprayed on Flavorcrest peach trees. Rates were calculated to deliver the same amount of calcium (approx. 400 ppm) for each material. Calcium concentrations were measured in the spray tank after mixing and averaged for 3 different spray dates.
The amino acid complex was able to increase skin calcium by about 20%, and perhaps higher rates could increase it more and even move calcium into the flesh of the fruit. If calcium concentrations can be increased substantially, there should be an improvement in postharvest performance of the fruit.
