The materials that our group will be putting into the Eco-column will be moist soil from a fertilizing plant so that the soil will have good nutrients in it.

We will also put a small fern into our Eco-column so that it will produce a good amount of oxygen for the organisms to survive.

We will add water from Zeekoevlei so that our Eco-column can produce water for the soil to stay moist and for plants to grow.

Our last thing that we will add is Earthworms to provide nutrients for the soils when an organism dies

Out.
