Building a Compost Lab
Biology 5TH Period
Composting is nature’s way of recycling and is the key to healthy soil and a healthy environment. Composting is a cost- efficient way of getting rich natural soil for a very cheap price. There are numerous types of compost bins available to make; each enable the growth of lawns and gardens. A compost pile is usually made from fruit and vegetable scraps, newspaper and grass clippings, worms (that act as decomposers), and leaves.
According to the concept of composting it is more than likely that rich filled nutrient soil will be produced from the worm compost bin at the end of a twenty day period. Rich soil that one buys at the store will be the same as a cost efficient, home- made worm bin.
