Earth ponies are one of the three main species of ponies found in Ponyville. Originally the founders of Equestria, they are closely linked to farming. The Apple family keeps orchards all around Appleloosa and Ponyville. Most earth ponies also do a lot of labour work, from plowing and sowing fields to scoring the ice and clearing the snow on the ground. However, not all of the earth ponies are farmers. For example, Hoity Toity and Cheerilee are examples of earth ponies that are not farmers.
Even though they don't have anything like horns or wings, they still have one type of magic. The type is that out of three species of ponies, when Earth ponies plant or touch soil, seeds, plants, etc., it seems to grow about twice as fast.
