The Conservation Station team is partnering up with twenty-four Iowa libraries for this year’s youth summer reading programming. The 2013 program theme is “Dig into Reading” and the Conservation Station has a new set of activities devoted to learning about soil. Visitors travel through three different stations to learn about soil formation, how to protect such a valuable natural resource, and even get a chance to make some edible soil to take with them.
Station #1: Soil Caldron
This station provides the opportunity to learn about the different parts that make up a healthy soil by following the soil recipe. Kids add parent material, nutrients, bacteria, water, earthworms and other living organisms, organic material and sunlight to the caldron and mix well. When we look into the caldron we see that soil hasn’t formed yet because the most important ingredient was left out – TIME! It takes between 500-1,000 to form just one inch of soil.

Station #2: Rainfall Simulator
At the rainfall simulator, visitors can see how different land covers help protect soil and keep it from polluting our waters. Featured are trays simulating intense tillage, no till, perennial vegetation, cover crops and impermeable urban services.

Station #3: Edible Soil
The final station allows kids to make soil that they can enjoy immediately instead of waiting 500-1,000 years. Edible soil combines chocolate covered candies, chocolate pudding, crushed chocolate sandwich cookies, colored sprinkles, gummy worms and yellow sprinkles into a delicious snack that ties together everything they learned at the first two stations. Check back soon for the edible soil recipe and directions.
