Humanity has spent tens of thousands of years developing the grain harvesting process, a process that is inextricably linked to the practice of agriculture itself. What began at the end of the hunter-gatherer era has stayed with us to the modern day, with humankind enjoying the same plants as our ancestors, albeit in slightly different final forms. While this story spans millennia, read on to learn a quick history of the grain harvesting process.

Agricultural Origins and Early Cultivation

A decline in nomadic tendencies marked the end of the hunter-gatherer era. As people stopped moving around with each passing day and settled in specific places, it quickly became apparent that they needed sustainable solutions for food. Otherwise, it wouldn’t take long for people to hunt all the wildlife and eat all the edible plants in each area.

As villages cropped up, so too did crops. We know that people started eating wild grains at least 105,000 years ago, although it is possible that this began even before that. At some point, after people started eating grains, they took to planting and harvesting them.

After 9500 BC, we saw “founder crops” appear. Founder crops were the main types of grain domesticated in Southwest Asia, which became the foundation of agriculture worldwide. The founder crops included barley, bitter vetch, chickpea, einkorn wheat, emmer wheat, flax, lentil, and pea.

100 BC to 1600 AD

Throughout the Middle Ages in Europe, grain harvesting and other agricultural efforts grew to a massive scale. Although no large machines were pumping out carbon dioxide, efforts across the globe to domesticate cattle saw an incredible increase in methane. From 100 BC to 1600 AD, methane emissions grew by around 31 million tons yearly. To put that in perspective, a Toyota Camry weighs about 3,500 pounds—that’s almost 18 millionToyota Camrys worth of methane every year.

Suffice it to say, 100 BC to 1600 AD was a big turning point for global agriculture. While grain was still being harvested manually (typically with scythes and sickles), incredible amounts of grain were harvested. That’s because about 80 percent of the entire European population were farmers.

By the year 900, European farmers had also implemented three-field crop rotation, a process in which one field is left as fallow every year. This was an incredible change in the nutrient content of grain in Europe and also improved productivity.

The 1600s to 1800s

After the introduction of the potato to the European diet in the late 1500s, European nutrition improved dramatically. By the time the 1700s rolled around, the potato was a staple crop that increased the food supply and even reduced disease and mortality rates. The potato allowed people to become less reliant on grain, which was a direct response to multiple national and regional famines that arose when grain crops failed.

Unfortunately, potatoes could not escape the same fate, and a growing dependence on tubers led to the European Potato Failure and countless deaths all over Europe.

Around this time, new farming techniques were invented around Europe, like the seed drill in 1701 and the stationary-steam-engine-driven threshing machine in 1812. As these advancements made it over the pond, agriculture was at a height like never before.

Eventually, a combination of factors (namely convenience and capitalism) led to the creation of steam-powered grain elevators in Buffalo, New York. Shortly after the completion of the Erie Canal, it became clear that Buffalo’s position on the water made it uniquely suited as a grain kingpin in the United States.

Through the 1830s, Buffalo’s port grew more and more outdated until the invention of the steam-powered elevator in 1843. This invention made it easier to store grain, benefiting both farmers and the producers who would buy the grain.

The 1900s

The dawn of the 1900s (more accurately, a year later in 1901) saw the invention of the first gas-powered tractor. Draft animals became things of the past, and self-propelled harvesters grew and grew in popularity. With fertilizers increasing the nutrients and success of crops, productivity grew like a weed. However, as farming became more accessible, the number of farmers dropped. By the 2000s, American farmers fell from 24 percent to just over one percent!

Green Revolution

From the 1940s to the 1970s, the world saw some of its most significant leaps forward in grain harvesting and other agricultural efforts. Irrigation infrastructure expanded, management techniques entered the modern era, and hybridized seeds were widely distributed. These revolutionary ideas were championed by Norman Borlaug, a man who is now credited with saving more than one billion people from starvation.

Modern Harvesting

Today, grain harvesting is still a hugely important part of culture worldwide. People in the United States can’t enter a grocery store without seeing the benefits of grain harvesting, and people worldwide rely on annual grain crops as their primary food source. Now, we enjoy the benefits of tens of thousands of years of growth and evolution, with giant combines making the harvesting process occur in mere minutes.

Gigantic grain storage bins and grain elevators make the once-complicated storage process a simple matter, and it’s easier than ever for farmers to avoid spoiled yields with all we know about the optimal moisture content of grain.

Even things you may not expect to influence grain harvesting, like computers and the internet, have a hand in the success of the grain industry today. Tracking fertilization and yields and managing genetic maps and feed additives are all made simpler with new technology.

Now that you know this quick history of the grain harvesting process, we hope you have a greater appreciation of the incredible strides that humanity has taken to get to where we are today. Remember, this is a quick history.
