Corn maze

Mazes may cover . Larger mazes can have more design details. In 2012, a maze in Lacombe, Alberta, Canada earned the Guinness World Record for the largest scannable QR code on Earth. == Designs ==

Designs may be simple lines, or they may produce an overall image that can be seen from above. Many are based on artistic designs such as characters from movies. Some mazes are even created to tell stories or to portray a particular theme. Complex designs include those featuring popular singers, farming themes, patriotic themes, Complex designs may be produced by a specialty company. A large maze may be broken into several sections. In other cases, the corn is planted to form the maze, using GPS mapping technology. == Revenue ==

Corn mazes are usually created because they can bring money into a family farm. Some farms also donate a portion of the proceeds to a charity. == History ==

The first full-size corn maze is said to have been created in Annville, Pennsylvania in 1993, although the Los Angeles Times mentioned the existence of a corn maze at the R&H Ranch, in Lancaster, California, in 1989. == Creation ==

In order for farmers to create a corn maze they must carefully plan their production, design, and marketing techniques in advance: • Planting the correct variety of corn is important for the success of a corn maze. Farmers must consider stalk strength and height when selecting the right hybrid to plant. • Farmers must watch for stalk rot since it is one of the most frequently observed diseases. Key factors for stalk rot include improper fertilization, moisture stress, and disease development. • Moderate plant population (about 20,000 plants per acre) would be considered ideal. If moderate plant population is not followed crop crowding can occur. • Since farmers planting for corn mazes are not growing the crop for maximum yield they should not apply too much nitrogen fertilizer. Rutgers Cooperative Research and Extension recommends the total nitrogen rate for the season should not exceed about 125 pounds per acre (140 kg per hectare). • Corn maze crops should be planted from mid to late May in the northern hemisphere, or mid to late November in the southern hemisphere. This is two to three weeks later than crops being planted for grain. • When cutting the walkways farmers must cut the internal growing point of the stalk off to avoid regrowth. Some farmers use herbicides, roto-tillers, or mowers to cut the walkways. ==See also==
