Manganese is found as a salt in the soil.
Manganese serves with iron in the manufacture of chlorophyll. It may also aid in nitrogen assimilation and synthesis of protines. A deficiency of manganese also disturbs carbohydrate metabolism, and results in chlorosis and retarded growth.

Conifers Symptoms:
Are similar to symptoms of iron deficiency with new growth being stunted and chlorotic. Older needles and the lower crown will remain green.
