We all love our teachers, but looking back there are things we wish somebody had told us. Here are six things about agriculture that I wish were taught in school.
Food is not easy to grow.
On TV you always see farmers portrayed as a bunch of uneducated hillbillies, but that is not the case! There is a lot more to growing food than most people realize; farming is a science. Farmers have to be masters of chemistry, agronomy, physics, mathematics, economics, and meteorology. In fact, there are over 70 colleges across the country that offer degrees in Farm Management. Who knew?
Most of the corn we see in the fields isn’t sweet corn.
There are several different types of corn grown in the US, but the main type is field corn, also called dent corn. This corn is used for animal feed and also processed into ethanol, corn syrup, and other products like makeup and plastic. Less than 1% of the corn grown in the US is sweet corn! Check out this math lesson teachers could use to teach students about corn.
Dirt is not the same everywhere you go.
Have you ever wondered why Arizona soil is so much redder than the dark black soils we have here in central Illinois? It turns out there is much more to dirt than meets the eye. All soil is made up of a combination of three components: sand, silt, and clay. The way a soil looks, feels, and even how well crops can be grown in it can all be predicted by looking at the age of the soil (some soils are thousands of years old!), mineral composition, topography of the land, and what the native vegetation was. There are even people whose whole job is studying soil!
Hamburgers and milk don’t come from the same place.
Everyone has seen the Chick-fil-a commercials where the black and white cows are telling you to eat more chicken, but besides being a cute marketing strategy it doesn’t actually make sense. Holsteins, like the Chick-fil-a cow, are one of hundreds of breeds of dairy cattle that are milked to make cheese and ice cream, but very rarely used for meat. A more accurate commercial would have a Black Angus because they are the most common beef breed in the US. These are the cattle that are raised for their meat to be processed into steaks, roasts, and burgers.
Farmers do care about the environment.
The media is always pointing its finger at the agriculture industry for polluting the atmosphere or causing global climate change, but farmers really do care about the environment. In fact, they are affected even more than the rest of us by global climate change. As the climate patterns change over time, new pests invade our fields that they are not equipped to handle. This in turn lowers their yield and actually costs them money!
There are chemicals in your food. Gasp!
Pyridoxine, Natamycin, and Carboxymethylcellulose, oh my! Find out what these chemicals are. Just because something has a long name doesn’t mean it’s bad. In fact, all food is naturally made out of chemicals called vitamins, minerals, and antioxidants. A chemical-free diet would mean that you couldn’t eat anything!
