About Ponwith Farms

Corn: A Relative of Grass

The field corn is related to the grass you have at home in your lawn. The biggest difference in these corn species is that your lawn puts on a seed head where the field corn puts on a cob. On a typical ear of corn, there is approximately 600 kernels on each corn cob.

Corn can take almost six months to grow to the nine foot tall plant shown in the video. One plant could potentially provide 3-4 ears, however, farmers want one big ear per plant.

About Field Corn

Sweet corn is a different variety that you can eat with your family as a delicious treat for dinner. Field corn is a different species. It doesn't have as much sugar in it. This corn speciality is starch and energy. The reason this is grown is for fuel, fiber and food. On the Ponwith Farms, their corn goes to an ethanol plant in Janesville, Minnesota that goes into vehicles on the road.

The rest of the corn that is left after being used at an ethanol plant is distillers grain. Distillers grain is a great source of food for livestock. Corn kernel can also be used for feed. It will get ground up at a feed mill with additional ingredients to be added in to feed livestock.

Let's Check Out the Combine

The combine's job is to take the husk into the corn head and remove the ear from the plant. The ear is brought to the center of the combine and processes it to take the kernels off of the cob. The leftovers (chaff) is disbursed back onto the field.

For more about combines, make sure to check the video above as Ryan and Emily provide great information about combines in terms that are easy for everyone to understand.
