True or False: Herbicides that are adsorbed to the soil are inactive.

Herbicides that are adsorbed to the soil can indeed become inactive in the sense that they are no longer available to effectively control target plants. When a herbicide binds strongly to soil particles, it reduces the likelihood of the herbicide being absorbed by plant roots or leaves, which diminishes its potential to act as a chemical agent against weeds.

This process of adsorption can lead to a scenario where the herbicide is present in the soil but is not in a form that is accessible to the target plants, thus limiting its efficacy. However, it's important to note that some herbicides can still exhibit some activity even when adsorbed, depending on their chemical properties and the environmental conditions.

In this context, the answer is true because, generally speaking, when herbicides are adsorbed to the soil, they are rendered inactive in terms of their ability to control unwanted vegetation. However, the level of inactivity may vary depending on specific herbicide properties or soil conditions.
