What does landscaping involve in relation to agricultural practices?

Landscaping primarily involves the modification of land to improve its aesthetic appeal. This can include the design and arrangement of plants, trees, flowers, and other features in both residential and commercial spaces. The practices within landscaping often focus on enhancing the visual aspects of an area, creating pleasing outdoor environments, and utilizing space effectively.

In contrast, the other options reflect agricultural activities that have different emphases. Studying soil health and nutrition is a fundamental practice in agriculture focused on enhancing crop growth and productivity rather than aesthetic considerations. Growing and harvesting fruit is a specific agricultural endeavor aiming at food production. Similarly, planting cover crops for soil management is a technique used to improve soil health but does not pertain to the visual enhancement of landscapes. Therefore, option B stands out as the most accurate representation of landscaping's main function in relation to agricultural practices.
