Grasslands need time to rest when cattle and other animals are feed on them. Moving animals from 1 one area of pasture to another can provide the time needed for new growth. This is called . rotational grazing, and we received a question from Zhang Guohui in China about how it works.

Experts say rotational grazing is good for the land and the animals, and it can save money. This form of grazing can reduce the need for pesticide treatments by reducing the growth of weeds. And it can limit the need for chemical fertilizers by letting animals animal waste do the job of natural fertilizer. Rotational grazing can even help prevent wildfires by keeping grasslands in good condition.

Letting animals feed continually and intensively in the same grazing area can require costly replanting. . Animals eat the most desirable growth first. When that keeps happening, the roots do not have enough time to recover. As a result, less desirable plants may replace them.
