The best way to determine if an element is essential for plant growth is to grow a plant using hydroponics with and without the element. This experiment would allow for a controlled comparison between the plant grown with the element and the plant grown without it, and would provide direct evidence of the element's necessity for plant growth. The other options may provide information about the presence or concentration of the element, but do not directly test its importance for plant growth.
