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.
