Background

Keith Reynolds

Plants produce their own food using the energy from light and nutrients found in the soil. This is called photosynthesis. If they have trouble attaining these nutrients then they may whither and die, or experience simple growth problems. Many plants use different types of nutrients for growth, all according to what they get in their environment.

Changing the pH of the soil, helps make different chemicals in the soil more accessible. The world is filled with many plants which thrive in many climates. Each species has it's own needs and preferences. The multiple types of soil, each supporting a different pH, grow different plants. This test is designed for the growth of strawberry plants because of the massive amounts of sunlight needed. Other plants may not require as much sunlight.
