Question

If there is a high amount of fertilizer present in soil and it is deficient in water, then what will be the effect?
A. Overgrowth
B. Undergrowth
C. No effect
D. Wilting of plants

Answer 1

Hint: Fertilizers are chemicals that are administered to the soil to meet the nutrient requirement of the plant. They are administered locally or externally and are absorbed by the plant roots along with the water from the soil.

Complete answer: The movement of water is often from a region of high water potential to the region of low water potential. Water potential always depends on the number of water molecules in the system or the solution.
If in a condition soil is poorly watered but it is rich in fertilizers or has a high concentration of them, the water potential of soil will decrease.
Thus the soil solution will be hyperosmotic when compared with the cell sap and the roots might not absorb any water and it will ultimately lead to wilting.

Hence the correct option is D, Wilting of the plants.

Note: Fertilizers are important for providing nutrients to the soil, their increased concentration leads to ill effects on the plant due to the toxicity produced by those nutrients. Water from the soil can not be absorbed by the roots because of the high concentration of fertilizers.
