Answer:
Hypertonic soil
Explanation:
In the case study, the young farmer added 60% more fertilizer believing that more fertilizer would simply cause the plants to grow faster. He thought that, since fertilizer helps plants grow, more fertilizer would simply accelerate the processes. He created, however, a hypertonic soil environment rich in potassium and phosphorous, causing the water to leave the corn cells to go to the soil (osmosis effect) leaving them to wither.
