How many cows can grass graze only on 20 acres?

The number of cows that can graze on 20 acres of grass depends on various factors, including the type of grass, the quality of the pasture, and the grazing management practices used. On average, a general rule of thumb is about 1 cow per 1.5 to 2 acres for good quality pasture. Therefore, 20 acres could support approximately 10 to 13 cows, but this can vary widely based on specific conditions. Proper rotational grazing can also help increase the carrying capacity of the land.
