After reading about fish-based fertilizers in Volume 3 of Grow magazine, I began to wonder if mercury contamination was a concern.

I know that when eating fish, mercury can be an issue. Is this also a concern when using fish-based fertilizers on you soil?

Is the mercury removed from these fertilizers? If mercury does end up in the soil, do the plants absorb it or is it just ignored and left in the soil?

Thanks in advance for any information.
