Iron EDDHA is the best chelate for higher pH soils applied bia soil injection. This stuff is WAY better than the old sulfate and EDTA forms we use to use back when I got into the industry. Creating larger beds is a better long term solution. Many benefits there but I dont have time to get into soils and OM and whatnot right now. Let me live Levi.
Have you soil tested to see if you also have higher % of lime in your soil as well. Limey soils resist attempts to lower pH with sulfur if you were thinking of going that route.
Tests will also tell you if you're also potentially having other micronutrient problems of availability such as Mn.
