Composting clamshells is an excellent source of plant micronutrients and trace minerals that benefit plants. Crushed clamshells can furnish a range of micronutrients and trace minerals for plants, including calcium carbonate (to balance pH levels), magnesium, and boron.
As they decompose, these seafood shells release valuable trace minerals into the ground, such as magnesium, manganese, iron, and boron. It turns out that clams aren’t just good eating; their discarded homes provide nourishment for our green friends, too.
You’ve learned how these often-discarded seafood remnants offer valuable nutrients like calcium carbonate and trace minerals. When added to your compost pile or bin, they improve the quality of your organic material over time.
