Why are surface-applied fertilizers often preferred in certain situations?

Surface-applied fertilizers are often preferred because they are easy to apply and economical. This method allows for quick and efficient fertilization with minimal equipment or labor, making it accessible for both residential and commercial applications. The application process is generally straightforward, requiring less specialized knowledge and tools compared to other fertilization methods, such as sub-surface or incorporation techniques.

In addition to being user-friendly, surface-applied fertilizers typically have a lower cost compared to other options. This cost-effectiveness makes them an attractive choice for maintaining landscapes and gardens, particularly for those managing budget constraints.

Furthermore, the quick release of nutrients from surface-applied fertilizers can lead to rapid uptake by plants, enhancing their growth and health in a short amount of time. This immediate impact can be particularly desirable in situations where prompt nutrient availability is needed.

Other answer choices, while they might have some merit in different contexts, do not capture the primary reasons for the preference of surface-applied fertilizers in many situations. For example, while deep soil penetration is beneficial for certain applications, it's not a characteristic typical of surface application. Similarly, the requirement for more frequent applications might indicate a limitation rather than an advantage, and changes in soil structure through fertilization tend to be a more indirect effect that surface applications
