What is the relationship between traffic intensity and nitrogen needs?

The correct choice reflects the understanding that higher traffic intensity leads to increased nitrogen needs for plants. When an area experiences higher traffic, such as from vehicles or foot traffic, the soil structure can become compacted. This compaction not only affects root growth but also limits the availability of nutrients, including nitrogen, essential for plant health.

As compaction occurs, plant roots cannot access nutrients as efficiently, and consequently, they may require additional nitrogen to support healthy growth and recovery from stress. Therefore, when traffic intensity increases, plants often need supplementary nitrogen to compensate for the adverse effects of compaction on nutrient uptake.

This relationship highlights the importance of assessing traffic patterns when planning fertilization strategies in areas susceptible to heavy use, ensuring that plants receive sufficient nutrients to thrive despite external stressors.
