Which of the following is not a method of improving range land?

Overgrazing is not a method of improving rangeland. In fact, it is a harmful practice that leads to the degradation of rangeland. Overgrazing occurs when too many animals are allowed to graze on a particular area of land for an extended period of time, without giving the plants enough time to recover. This leads to the depletion of vegetation, soil erosion, and other negative impacts on the ecosystem. On the other hand, controlled stocking, rotational grazing, use of fertilizers, and introduction of legumes are all methods that can be used to improve rangeland. Controlled stocking involves managing the number of animals that graze on a particular area of land to prevent overgrazing. Rotational grazing involves moving animals from one area of land to another to give the plants time to recover. The use of fertilizers can provide essential nutrients to the soil, while the introduction of legumes can increase the diversity of plant species and improve soil health. Overall, overgrazing is not a viable method for improving rangeland, and can have serious negative impacts on the environment.
