Russell Tree Experts — Iron and Manganese Deficiency

2020-4-13 · Iron or manganese deficiency in trees occurs when a tree''s roots are unable to take up these minerals from the soil. Some may believe that this is due to a lack of said nutrients in the soil, but in most cases, it is due to the high pH of the soil. pH is used to measure how basic or acidic a solution is. 0 is highly acidic, 14 is highly basic, and 7 is considered neutral.

Manganese Removal
