Plant growth is important to agriculture because farmers need to produce food efficiently. Fertilizer assists in plant growth. Farmers select fertilizers they believe will not only make their plants grow larger, but faster as well. You can conduct science experiments related to the speed of plant growth. You need only a few supplies for each project and a week or two of time to complete them.
This science project determines if the amount of fertilizer used will make a plant grow faster. To make an accurate determination, you must have three plants all the same size, in the same size and type of container and existing in the same conditions. Place the three plants in a sunny location and water them daily. In one container, put no fertilizer at all. In the second container, place ¼ cup of fertilizer. In the third pot, place 1 cup of fertilizer. Use the same type of fertilizer for each plant and work the fertilizer into the soil of each of the two pots. Check on the plants daily and water as needed. Observe the differences in the plants and take pictures of their progress over a period of two weeks. See if there is a difference between the plant without fertilizer and the two plants with fertilizer.
Both store-bought and natural fertilizers are believed to assist plant growth, but which type of fertilizer makes a plant grow faster? Find out by getting two of the same size and type of plants in the same size container. Add ¼ cup of cow manure to the soil of one of the plants and ¼ cup of manufactured fertilizer to the soil of the other plant. Water both plants and place them in a window where you can monitor them daily over the course of two weeks. Note any changes in growth and whether or not one fertilizer seems to make one plant grow faster than the other.

Does a plant grow faster if it receives fertilizer more often? In this experiment, use two plants in the same size pots that are the same type and size. For one of the plants, put nothing in the soil. This plant is your control plant. In the other container, put ¼ cup of any type of fertilizer in the plant's soil. Add ¼ cup of fertilizer to that plant every day for a week. Make sure to work the fertilizer into the soil and water both plants as needed. Place the plants in a sunny location and monitor them daily. Note if there is any difference in the growth of either plant.
Find out if one organic fertilizer is more effective in making a plant grow faster than another. You will need two types of organic fertilizer, two plants of the same size and type, two containers for the plants that are the same, soil, water and a sunny location for the plants to grow. Mix ¼ cup of one type of organic fertilizer into 1 cup of soil in one container and ¼ cup of the other type of organic fertilizer into 1 cup of soil in the other container. Put one plant in each of the containers and water both plants. Set the plants in a sunny location and keep them watered as needed. Observe the plants everyday for a few weeks and make note of any differences in the plant growth. Which organic fertilizer makes a plant grow faster?
