Transcript of Compost vs. Fertilizer

Compost vs. Fertilizer Table of Contents 1. Abstract Abstract The purpose of this experiment is to find out what will work better to help your plants grow better, compost or fertilizer.

The procedure of the experiment is to plant six beans in six cups. Three of the cups have compost in them and the other three have liquid fertilizer. We would record the beans for a 7 day period and record the results.

The conclusion of our experiment was that compost worked better than fertilizer because 2 beans planted in the soil with fertilizer didnt grow at all and the beans planted in compost grew almost twice as much as at did with fertilizer. 2. Safety Sheet Safety Sheet There were no hazards during this experiment. 3. Acknowledgments Acknowledgments We would like to thank my guinea pig, Tuya, for letting us use her poop for our experiment. 4. Purpose & Hypothesis Purpose and Hypothesis The purpose of the project was to see what could help plants grow better, compost or fertilizer.

Based on the research done we have decided that natural compost will work better than fertilizer because compost feeds the soil and adds nutrients that the plants need unlike fertilizer that just feeds the plant and if you add too much it could kill the plant.

The independent variable in our experiment is the compost and fertilizer.

The dependent variable is the height that the plant grew in the seven days that it was measured.

The controlled part of the experiment was the plants, soil, place, amount of water, and the amount of fertilizer. 5. Review of Literature Review of Literature In our research we found out that the guinea pig is a vegetarian so the poop is a great way for humans to compost. The poop is very rich in nutrients such as iron, zinc, and potassium that plants need to grow. The nutrients could only mix in with the soil when you turn it into liquid fertilizer. To make this liquid fertilizer you put 2 cups of water for every cup of poop you collect and put them in a lidded container. Mix the poop with the water by shaking the container and drop the substance in the soil, mix it until the poop is not noticeable anymore. The reason compost is better than fertilizer is because compost is packed with nutrients that strengthen the plant tissue and helps the plant fight diseases and insects unlike fertilizer that makes the plant grow too fast and makes the tissue have a very weak layer that can't protect it from disease and insects. 6. Materials & Procedure Materials & Procedure Liquid fertilizer
12 cups (6 with holes on the bottom)
Guinea pig poop
6 beans 1. Gather all materials.
2. Gather guinea pig poop.
3. Mix guinea pig poop in a lidded container and add two cups of water for every cup of pellets.
4. Combine the mixture with soil and mix it until compost isn't noticeable.
5. Place soil with guinea pig poop in three of the six cups and label them "compost 1-3."
6. Place a bean in each of the three cups.
7. Combine fertilizer with water and mix it.
8. Place soil in the remaining 3 cups and label them "fertilizer 1-3."
9. Add the mixture of water and fertilizer to the soil.
10. Plant the remaining 3 beans to the cups labeled fertilizer 1-3.
11. Place a second cup on the bottom of each cup so the water stays in the cup when you water the plant. 7. Results 8. Conclusion 9. Bibliography Results Conclusion Our conclusion was that our hypothesis was right and that compost did work better than fertilizer because the beans grew more than the beans that were put in soil with fertilizer. We were also right that fertilizer could kill the plants because 2 of the bean plants in fertilizer didn't grow at all.
