This experiment was conducted to test how acidic soil will effect Brassica rapa. To perform this experiment, 100 Brassica rapa seeds were needed and an acidic solution, with a pH level of 4 and a neutral solution with a pH of 7. Additionally, 100 containers, approximately 5cm by 5cm, and 7.5cm deep were also needed. The containers were filled 2/3 high with potting soil and then one seed was placed in the middle of the soil. The remaining portion (about 1/3 of the container) was filled with additional potting soil. Every Tuesday, Thursday, Saturday, and Sunday evening, 50 plants were watered with 6ml of the neutral solution, making that the control, and the remaining 50 plants were watered with 6ml of the acidic solution, making that the variable used to compare with the control. The pH of the soil was taking pre-watering for both the control and variable and after watering for both the control and the variable. Furthermore, the percentage of plants, for each the control and variable, with growth were recorded, and the average height of the plants recorded with growth.

After completing this experiment, it was proven that an acidic solution reduces the rate and growth of Brassica rapa plants. The growth of the plants watered with an acidic solution ranged in height from 0.635cm to 1.27cm over a period of 13 days. The plants watered with a neutral solution ranged in height from 2.54cm to 7.62cm over a period of 16 days. This clearly states
that Brassica rapa plants will grow more successfully when watered with a neutral solution, with a pH of 7, which is regular tap water.
