Which of the following practices should be carried out by a farmer to encourage regrowth of pasture species?

To encourage regrowth of pasture species, a farmer should carry out controlled burning. This involves burning a small area of the pastureland, which helps to remove dead plant material and promote the growth of new shoots. Burning also helps to control invasive species that may be competing with desirable pasture species for nutrients and sunlight. However, it is important to note that controlled burning should only be carried out under appropriate conditions and with proper safety precautions in place to prevent the fire from spreading and causing harm to people or property.
