Though pesticides and herbicides kills pests that can destroy crops, this will also permanently harm the soil and even the crop itself. This may lead to a lesser harvest for the coming harvest season to come.

Overirrigation in dry areas can cause __________.plant growth that suffers as a result of high relative humidity from evaporation from the irrigation water
the formation of a plowpana buildup of salt in the soil to the point where it negatively affects plant growth
a minor problem that affects only a small area and is easily corrected

Answers

Answer:

the formation of a plow pana buildup of salt in the soil to the point where it negatively affects plant growth

Explanation:

The overirrigation can damage the roots of the plants and hence cause the soil to be leaky and accumulation of high salt contents. Thus the plants will suffer from the salt-laden water and thus creating water stress. Hence adequate drainage is essential for the plants to develop and irrigation should take place with clean water.

Final answer:

Overirrigation in dry areas primarily results in a buildup of salt in the soil, also known as soil salinization, which can negatively impact plant growth.

Explanation:

Overirrigation in dry areas can primarily cause the buildup of salt in the soil, also known as soil salinization. This occurs as a result of the evaporation of irrigation water, which leaves behind residual salts that are not sufficiently flushed away by rainfall in dry areas. Over time, these salts accumulate and can reach levels that are harmful to the plant growth.

While it's true that overirrigation might cause other problems like high relative humidity that may indirectly impact plant health, or the potential for minor localized issues, the key problem specifically linked with overirrigation in dry areas is the buildup of salt in the soil.
