A headland is sort of like a driveway for tractors and other big machines on a farm. You know how your parents have a driveway for your car to park on? Well, farmers have a special spot where they can turn their tractors around and drive back in the other direction.
This special spot is usually at the end of a row of crops. The farmer needs to turn the tractor around because they can’t just drive over the plants. It would crush them and they wouldn’t grow right. So, instead, they drive to the end of the row, turn around in the headland, and then drive back down the next row.
Sometimes, the headland area is left unplanted so that the farmer always has a place to turn around, and sometimes it’s just wider than the rest of the rows. Either way, it’s an important part of farming because it helps keep the crops healthy and the farmer’s equipment safe.
