问题 How does rotational grazing reduce the need for pesticide treatments? [br]  
Grasslands need time to rest when the cattle and other animals feed on them. Moving animals from one area of pasture to another can provide the time needed for new growth. This is called rotational grazing. Experts say rotational grazing is good for land and 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 the animal waste do the job of natural fertilizer.
