What Effect Do Different Fertilizers Have on the Vitamin C Content of Steamed Vegetables?

CSEF · 2013 Plant Biology

Overview

Objectives/Goals The purpose of my science project is to determine what effect different fertilizers have on the vitamin C content of steamed vegetables. The reason I am doing this investigation is to find the healthiest way to grow vegetables. If we are going to eat vegetables to keep us healthy we should try to maintain its nutritional benefits. I am using organic and inorganic as my fertilizers to grow vegetables. Methods/Materials 1. Garden pots 9. carrot seeds 17.Steaming basket 2. Water 10. Broccoli seeds 18. Stove top 3. Potting soil 11. Winter squash seeds 19. Drainer 4. Organic fertilizer 12. summer squash sees 20. Test tubes 5. Inert fertilizer 13. Measuring cup 21. Marker 6. Green house 14. Knife 22. Log book 7. Seed starter 15. Cooking pot 23. Gloves 8. Cutting board 16. Vitamin c test solution 24. Vitamin c control I will be using plain potting soil to grow vegetables as my control. Which I will steam vegetables for 5 minutes, I will then use a food nutrient kit to determine the levels of vitamin C, and will record results in data book. In my testing I will add fertilizer to soil to grow vegetables. Then I will steam vegetables for 5 minutes, I will then use a food nutrient kit to determine the levels of vitamin C, and will record results in data book. I will repeat this test with other fertilizer and perform 10 trials per test group. The experimental test variables that I am using in my science project are: organic and inorganic fertilizer.The vegetables that I am using are broccoli, carrots, winter squash and zucchini. Results The results of my investigation to determine what effect different fertilizers have on the vitamin c content of vegetables show that all the methods of growing vegetables contained vitamin C, However growing broccoli with inorganic fertilizer was slightly more effective. Conclusions/Discussion After completing my project what effect do different fertilizers have on the Vitamin C content of vegetables, I have found that my hypothesis is incorrect, growing broccoli with Inorganic fertilizer actually maintained and supplied the most vitamin C.

Summary statement

Picking vegetables, grown and prepared the right way will allow us to get the most nutritional benefits: if we are going to eat our vegetables to stay healthy we should grow and prepare them in a way that wil offer the most nutrients.
