Goats help regenerate the soil by aerating and fertilizing the land with their hooves
HOW GOATS EAT WEEDS
If a weed is simply cut, it will react quickly to reseed itself, often returning stronger and heartier. But goats eat weeds in a way that stops that from happening. By eating the flower first, then each leaf off of the stem, the weed is left with no way to photosynthesize - and opens up space for the soil below.
Goats eliminate the need for pesticides, which are more expensive, harmful, and don't eradicate weeds effectively.
