# The Effects of Fertilizer on Plant Growth

Fertilizers are combination of minerals that nourish plants. However, use of too much fertilizer can have a negative impact on the growth of the crops or plants. That is why this amazing experiment has been designed to find out that how the amount of fertilizer used affects the growth of plants.  This project falls under the Botany category and is a perfect science fair project idea for high school students in order to learn science in a hands-on manner. Moreover, this project play vital role in creating awareness about the right use of fertilizers in the proper growth of the plants and crops.

Aim: To find out the impact of fertilizer’s proportion on plant growth
Estimated time project: 10 days

Things you will need to conduct the experiment:

– 15 plant pots
– Soil
– Measuring tape
– Calculator
– Graph paper
– Water

### Instructions

• 1

Fill the pots with soil

Take 15 small pots and fill them with same amount of soil.

Note: You can use the plastic pots or the disposable tins in your home to keep the project a low-budget one.

• 2

Now place one radish seed in each of the pots.

• 3

Divide the pots into groups

Now, divide the pots into five groups, three pots in every group. After that, label the groups as A, B, C, D, and E.

• 4

Water the pots

Now, make sure to water the pots in group A at least two times in a day with 30 percent of the suggested quantity of fertilizer. Water the pots of group B with 60 percent, group C with 100 percent, group D with 120 percent and group E with 150 percent.

• 5

Measure the height of the plants

Keep watering the plants for nine consecutive days and enjoy the various stages of the growth of radishes. Pick a measure tape on the tenth day and measure the height of the reddish plants. Now, calculate the average height for each group and record your findings accurately.
