What is the process of chemicals being washed out through the soil called?

Fertilizer Analysis
Leaching
Evergreen
Urea-formaldehyde

The correct answer is: Leaching

Leaching is the correct term for the process of chemicals being washed out through the soil. This occurs when water moves through the soil and carries dissolved substances with it. Fertilizer analysis, evergreen, and urea-formaldehyde are all incorrect choices because they do not accurately describe this process. Fertilizer analysis refers to the testing and analysis of fertilizers, while evergreen is a type of tree. Urea-formaldehyde is a type of resin, which is not related to the process of chemicals being washed out through the soil.
