soil test report

[jtnguyen333]

I finally dug a sample of soil from my trees and send it in for  a soil report.  The report came back.  According to the report, the soil is extremely low in nitrogen and high in sulfur.  pH is relatively high at 6.9.  I fertilize every two months.  Since the report, I used blood meal as nitrogen.  Is the cause of the problem is due to iron deficiency?  which is better for iron deficiency?  chelated iron or soil acidifier with iron?  thanks

If your soil is low in nitrogen, then add nitrogen.  Why would you think iron has anything to do with low soil nitrogen?  Blood meal does contain nitrogen, but a conventional nitrogen source such as urea, ammonium nitrate etc. would do a better job
