Which of the following management practices could decrease the production of herbage on a grazing land

Overstocking is a management practice that could decrease the production of herbage on a grazing land. This means that if there are too many animals grazing on a piece of land, they will consume more vegetation than the land can produce, leading to a decrease in the amount of available herbage. Overgrazing can also damage the soil and vegetation, making it harder for new plants to grow. On the other hand, practices such as irrigation, paddocking, and reseeding can increase the production of herbage on grazing land by providing the plants with the water and nutrients they need to grow, and by allowing the land to rest and recover between grazing periods.
