We'd love to have some advice as to what to amend the patch with this Fall. We have 3,000 square feet to work with. Thanks for the help! -Kristine

Your Iron/Manganese ration is high. I would add a few ppm of Mn to try and even it out. In my case, with OM higher than you and a ratio better than yours, I still have Mn deficiencies because it gets locked up.

Hence I didn't mention the Mn....LOL....Hopefully the manure will bring some along. Every time I've added Manganese to deficient soils we've failed to correct the problem. Oxides, Sucrates, etc have all ended up locked again even when applied at 7-15 times the prescribed rates.
Usually the most practical solution to an Mn deficiency is to make light frequent foliar solutions (chelated) during periods of rapid growth.
Plus I don't believe that few yellow spots on leaves has ever cost anyone the season. LOL....Tragically the radical attempts to CORRECT silly yellow spots have cost many growers the entire season.
Many a record fruit has been grown on Iron or Manganese deficient soil too.
