How does rotational grazing reduce the need for pesticide treatments? [br] [ori

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.

For much of the year, record prices for oil made oil-producing nations rich. Now these nations are trying to cut production to support collapsing prices. Less than six months ago, oil traded at a record one hundred forty-seven dollars a barrel. Governments and oil companies in Russia, Brazil and Saudi Arabia spent billions of dollars to develop new oil fields. Now, oil is trading for less than forty dollars a barrel—down over seventy percent.
