Conclusion by Marlies Emmelot

In the multiple tests we ran on the soil collected from my backyard, I learned many things about soil and how what the soil contains affects how well it grows crops. Through the fertility tests, we found that our soil was low in potassium and nitrogen. Although, it was at the correct pH level, which is between 6.5 and 7. We also found that there were little to no bugs in the soil. Through this experience, I found it interesting there were fertilizers that could add the nutrients your soil is lacking. This would allow your soil to grow more crops and grow faster as well. Through these tests we also found out that our soil is more clay than sand. The ribbon we were able to make out of our clay with a small amount of water added to it was not very long because every time I tried to make it longer, it would break apart. This gave me the idea that our soil was not completely clay yet was not completely sand either. The lettuce that we planted in our soil was successful and grew at about the same rate for both the remediate soil and the controlled soil. The lettuce has not yet sprouted but the leaves are growing rapidly.
