Conclusion

Maddie Currie

       During the making of this blog, the most important thing I learned about soil is that it is very important to the survival of humans and everything else on the planet. It is a home for countless microorganisms and insects. It is what we use to grow our food and without it, humans probably wouldn't survive.
       Soil is not all created equal, either. Some is more fertile than the rest. The soil we tested in these experiments was not very fertile because it had low levels of nutrients. I learned why farmers use fertilizers--to replace those nutrients and make the soil more fertile. This allows them to grow more food more quickly in order to feed our growing population. Before this project, I had no idea how much organic matter soil contained. It surprised me to see that during these tests.
       Soil and dirt are not the same thing. Dirt can be anything from dust to soil, but soil is special. It is made up of sand, silt, clay, and organic matter and soils from different places around the world have different characteristics like texture, porosity, composition, and nutrient content.
       Soil is the living skin of our planet and one of the most important things humans need to survive.
