Which statement is true about the advantages of cultivation as a weed control method?

• A. It reduces soil erosion and enhances soil structure
• B. It requires high energy and uses chemicals
• C. It can increase vine vigor and damage soil structure
• D. It provides no chemicals and incorporates fertilizers

Answer: (D)

Cultivation controls weeds by physically disturbing them and does so without herbicides, while also allowing surface-applied fertilizers to be mixed into the soil where the vines can access them. This combination—no chemicals for weed control and active incorporation of fertilizers—is what makes it advantageous. The other statements describe outcomes that aren’t typically considered benefits of cultivation: tillage can disturb soil structure and increase erosion; weed control that relies on chemicals or energy-intensive processes isn’t a characteristic advantage of cultivation; and while cultivation can influence vine vigor, the main point is the chemical-free weed control with nutrient incorporation, not boosting vigor or implying soil damage as a benefit.
