10 thoughts on “How does Fertilizer affect Transpiration?

  1. Hi Grace! I loved this! Your speaking was so clear and made your presentation really easy and pleasant to listen to. I didn’t have to strain to hear anything. If I have to provide a wish, I might suggest laying out a few more key words to really drill those important ideas into our minds. Other than that, there’s nothing I would change:) My question for you is: What was the inspiration behind this project? What made you choose transpiration?
    Super interesting to learn about. Thank you!

    1. Thank you for the kind compliments, Lara!
      My project was initially going to be about “How does the leaf size of air-purifying plants affect the plant’s ability to produce oxygen?”. However, in order to pursue that topic, I needed to have a way to measure carbon dioxide in the air and to measure the plant’s photosynthesis. After getting a bit of research, I noticed that the carbon dioxide measuring devices were very pricy. I emailed Ms. Mulder about some problems I was having, trying to choose the right inquiry question I could do an experiment on. She gave me some options and topics to consider and one of them was transpiration! I quickly did some research and noticed that it was close to my initial question and decided to pursue the topic for grade 10!

  2. Wow! I really enjoyed your video, and I learned a lot. You did a great job explaining the complex process of transpiration.

    Although your images helped explain your points, I think it would have been helpful if your key points/words were written down on your slides, but otherwise great job.

    In your talk you mentioned the effects of adding too much fertilizer and not adding enough, so I was wondering if there is a way to figure out roughly how much fertilizer a plant needs?


    1. Thanks Ruby! You are so sweet!
      Yes, I completely agree with you. I could not start all over and add the keywords to the powerpoint when I noticed the problem. I added subtitles on my stream video if that helps!
      It really depends on which fertilizer you are using and how concentrated your fertilizer is. Some other factors that the amount of fertilizer depends on are the soil, the crop you are growing and the weather conditions.
      https://plantcaretoday.com/apply-fertilizer-how-much.html recommends that for ordinary powered garden fertilizers, such as 5-8-7 (nitrogen-phosphorus-potassium), generally range from 3 to 5 pounds per 1000 square feet.

  3. Hey Grace! You spoke very clearly throughout the whole presentation and the information was very insightful. As Lara and Ruby also stated in their comments, I think adding key words into your slides would be useful to the viewers and would support your diagrams and info. You talked about how incorrect use or too much fertilizer would cause foliage like a chemical burn. Could you explain that in more detail? I’m curious as to what it means. Great job on your presentation!

    1. Thank you so much, Simran! I really enjoyed your presentation as well!
      When you add too much fertilizer to the soil, plants cannot take up water. Plants rely on an osmotic pressure gradient in order to collect water. When the pressure around the roots gets too high, the flow of water reverses. This is where the term burning your plants comes from. The leaves arent actually burned, but the leaves turn brown making it look burnt.
      Plants adjust to the variations in the level of nutrients around their roots but they grow the best if the level is consistent. In addition, Potassium in fertilizer can cause burns, because it has a high salt level. Putting too much fertilizer on a plant is the equivalent of pouring a bunch of salt on a plant. The salt takes all the plant’s moisture, making the leaves brown.

  4. Hey Grace! What an amazing presentation! This is the first I have heard about the transpiration process, so I learned lots from you. Furthermore, your voice was really powerful in this presentation, and I really enjoyed its clarity

    In addition to adding keywords to further support your diagrams and speaking, I felt like there was a disconnect between your main question and your presentation. At the beginning of your presentation, you didn’t really mention your question, and that made your presentation hard to connect to and process. I think that you can mention your question at the beginning of the presentation and refer back to it throughout the presentation to maintain consistency.

    I’m wondering how do different forms of fertilizers go through the transpiration process. Would you care to elaborate a bit more?

    Nonetheless, fantastic presentation! Really enjoyed it! Great job, Grace!

    1. Thank you so much, Joanna! Really appreciate it!
      I think I have already talked about the different ingredients in fertilizers and how it affects the plants. I am not sure if that is what you mean by different forms of fertilizers but I couldn’t find much info on different types of fertilizers. I’ll let you know if I find some more information on your question!
      I am glad that you enjoyed my presentation!

  5. Hello Grace!

    I really had fun watching your presentation! It was very organised and engaging. I like how you used images to help explain your points. One question I have for you is: how are you able to find out how much fertilizer a plant needs?

    1. Hey Amin!
      I am happy that you enjoyed my presentation! I enjoyed yours as well. Our topics are quite similar because they are both about plants!
      Ruby actually asked the same question! You can scroll up to read my answer.
