Though we call these “hay rides” – the grassy substance beneath the riders is actually straw – read on to learn more.

Oct. 9, 2018 – There are a lot of fun sayings out there that involve the word “hay”. “We better make hay while the sun shines.” “It is time to hit the hay,” and so on. In the fall, folks in the U.S. see hay stacked up around people’s front door. We go for “hayrides.” I have even seen giant, round bales of hay sitting out in fields that are decorated to look like jack-o-lanterns!

The funny thing is, most people never realize that most of the “hay bales” around their front door or the hay on a hayride are not hay at all!!

Most of these bales are made from straw, not hay. The next obvious question – what is the difference between hay and straw?

Straw refers to the plant material that is left over after grains like wheat and barley are harvested. The stems left behind become straw. Most of the nutrition of grain crops lies in the grain. The stalks that are remaining – the straw – are generally very low in quality and not very healthy for animals. It can be used as a part of animal’s diet if there is nothing else to eat, but it is usually considered a waste product and is harvested in bales and used for other purposes.

Straw can be used as bedding for animals, as stuffing for a mattress, and can be used to make things like a basket or a straw hat. Recently, straw has been used as a fuel source for bioenergy. There are also some handy uses of straw around the house, such as a mulch to prevent erosion when seeding your lawn or placed around strawberry plants to prevent the fruit from laying on the soil. Straw has also become popular as a building material. The walls of houses or buildings can be insulated with bales of straw – a natural product that is relatively cheap to use!! And, of course, straw is a very popular decoration for the front porch during the fall season.

When we talk about “making hay”, we are really talking about making something that an animal can eat. Hay is usually gathered up into bales, and stored for the animals to eat during the winter when the grass is not growing. In many parts of the world, farmers depend on hay to feed their cattle, sheep, or horses during the long winter period. In periods of drought, hay can also be used to feed animals when normal grazing is not enough. Many farmers specialize in growing hay that they sell to other farmers in their region.

We want hay to come from plants that are good and healthy for animals to eat. This could mean nutritious grasses like ryegrass or bermudagrass or from legumes like clover or alfalfa. Hay will often be a mixture of plants that can make it more nutritious. Growers need to be careful to not include plants that are poisonous. Hay is typically produced on perennial crops and often on land that may not be suitable for grain production. As such, it provides a valuable use for lands that would not be productive for other things.

The biggest difference between the production of hay and straw is that hay is typically harvested before the plants make seed and are just growing leaves. These leaves are packed full of nutrients and easy for an animal to digest compared to the low-quality stems left behind as straw. Those nutritious leaves are also more sensitive to the environment and can become moldy or damaged if they are rained on after harvest. So, the way growers store their hay is very important.

So, this fall, when someone asks you to go for a hay ride, you can let them know that it is technically a “straw” ride. While correct, I doubt that name will stick!
