The leaves on my pear tree have all turned yellow just since leafing out this spring and now have brown spots on the leaves. My other pear tree is just fine (about 75 yards away. Can you tell from photos what is wrong and what I need to do? Thank you.

This looks pretty severe! It appears to be a fungal infection, paired with a severe nitrogen deficiency. You can try wettable sulfur, and dolomitic lime to recondition the soil, but this tree looks like it is on its way out, unfortunately.
