kumquat trees

I have 3 2 year old kq trees. I had my soil analyzed and the results showed the soil lacking in nitrogen — guess that explains slightly yellow leafs. My questions are: (1) would it be beneficial to add a very small amount of ammonium sulfate 21-0-0 Fertilizer to boost the N level? and (2) the lab report indicated it would be beneficial to apply a foliar micronutrient spray. Can you recommend a specific micronutrient spray? (3) I also have blueberries with slightly yellow/brown leafs. Would a periodic application of the foliar spray help this condition and of course the resulting crop? Thank you so much. (-:

Yes. Ammonium sulfate also provides Sulfur, and important plant nutrient that is often deficient and overlooked.

(2) the lab report indicated it would be beneficial to apply a foliar micronutrient spray. Can you recommend a specific micronutrient spray?

I like Micrel from Growth Products company.

They are a GKH advertiser and they have an excellent line of plant nutrient products. You may also find benefit from the root stimulation product called Essential Plus, to be used as a soil drench.

And yes, for the blueberries too.
