Why must controls (such as plants given water only) be used in the fertilizer experiment
Controls are necessary in the fertilizer experiment to provide a baseline for comparison. By having plants that receive only water, researchers can isolate the effect of the fertilizer being tested. This helps ensure that any observed changes in plant growth or health can be confidently attributed to the fertilizer treatment.

The patch of soil that is not given fertilizer serves as the control group, providing a basis for comparison to evaluate the effectiveness of the fertilizer.
The one patch given the fertilizer is the experiment group. The other is the control.
