Question 1 Report

Which of the following practices is an example of a cultural weed control method?

Answer Details
Mulching is an example of a cultural weed control method. Mulching is the practice of placing a layer of organic material, such as leaves or straw, over the soil surface to suppress weed growth. The mulch acts as a physical barrier, preventing light from reaching the weed seeds and preventing them from germinating. Additionally, mulch can help retain moisture in the soil and suppress weeds by suppressing the growth of weed seeds that are already present in the soil. This is an example of a cultural weed control method because it does not rely on the use of chemicals or other external inputs and instead relies on natural processes to control weed growth.
