with the extreme amount of moisture than any kind of deficiency.  Anyone 
else in the upper midwest seeing the same thing?"


   The youngest leaves on one of my apple trees are turning yellow with the 
veins still green.  Checking the chart that I sent for the Spring Pomona, I 
learned that it is a symptom of a deficiency of iron or manganese.  But 
which?  Working the chart backwards, looking for symptoms of either iron or 
manganese, I learned that if the plant is dropping leaves prematurely, it is 
reacting to too much water.  Some leaves are dropping telling me that, with 
the excess water, either iron or manganese has become unavailable.  Rain has 
fallen for five to six days per week here in Central Minnesota.
