Sarah's class is studying soils. She read that scientists said that plants will growth in any soil type. Students in Sarah's class performed an experiment to see if this statement is true. When they started the experiment, they used the same type of plants and the plants were the same size. Light, water, temperature were the same for all pots; only the soil type was changed. Their results are seen in the table. What is the best conclusion for the students experiment? A) Clay is the best because it holds water for the planet roots.
B) The bigger the soil particle size, the better the plant growth.
C) Loam is best because it holds water and brings air to the plant roots.
D) Smaller particles are best because they hold lots of water and air for the plant.
