Soil content directly affects the flower color and height of the flowers. The data showed that flowers planted in nitrogen-right soil were on average 5 cm taller and much brighter in color than flowers grown in regular soil or a soil-clay mixture.

After reading about types of soil, Jennifer predicted: If the soil has a higher nitrogen content, then the flowers will be brighter in color and taller in height.

Alex placed each flower plant into a pot with a 50 cm diameter. He put regular soil in the first pot, a soil-clay mixture in the second pot and nitrogen-rich soil in the third pot. Each was watered equally and put in the same location.
