How would you modify a polygon feature to reflect two different crops grown on a plot of land?

To reflect two different crops grown on a plot of land, the most effective approach is to split the polygon and update the attributes. By splitting the polygon, each resulting shape can represent a different crop area within the same plot. This allows for precise representation and management of the land use, as each sub-polygon can have its own attribute data, such as crop type, yield, irrigation needs, and other relevant information.

Updating the attributes of the newly created polygons is crucial for accurately reflecting the crops grown in each area. This method ensures that all spatial and attribute information is correctly aligned and facilitates better analysis and decision-making regarding land management and agricultural practices.

The other options do not adequately address the need to differentiate between the two crops. Keeping the polygon intact without changes would not allow for distinguishing between crops, while splitting the polygon without updating attributes would fail to provide the necessary information about each distinct crop type.
