_______ is considered better than _________ for incorporating broadcast fertilizers.

The choice indicating that plowing is considered better than disking for incorporating broadcast fertilizers is accurate because plowing typically provides a deeper and more thorough incorporation of the fertilizer into the soil. This deeper incorporation ensures that the nutrients are more effectively integrated into the root zone where they can be accessed by plants.

Plowing turns the soil over, which allows for better mixing and can help to maintain soil structure and porosity. It also helps to break up compacted layers and incorporates organic matter, which can enhance soil fertility and improve nutrient uptake.

On the other hand, disking is generally used for shallower soil mixing and may not achieve the same level of incorporation as plowing. While disking can be faster and require less energy, its effectiveness at integrating fertilizers, especially at a greater depth, is less than that of plowing.

Therefore, the distinction between the two methods is based on how well they incorporate fertilizers into the soil profile, making plowing the preferred choice in this context.
