What materials did john used in his science fair project

Answer 1

• Seed

• Soil

• Organic fertilizer

• Chemical fertilizer

• Water

• Ruler.

What is a Fertilizer?

This refers to a substance which is added to the soil in other to increase the fertility and is commonly used in agriculture so as to maximize yield and sales by farmers.

The experiment John did was to measure the fertility of the soil after several substances have been added to it through the growth of the plant.

It was discovered that the plant in which chemical fertilizer was added to the soil grew faster than the rest when it was measured by the ruler which therefore makes the materials listed the most appropriate choice.
