How has agricultural land use evolved?

Land use in the United States has undergone a dramatic transformation over the past few centuries. From the early days of horse-drawn plows to the modern era of self-driving tractors and renewable energy, our relationship with the land evolves to meet changing demands. But how did we get to this point? Read on to learn about significant milestones in our history that have shaped modern agriculture land use.

The first American agricultural revolution

From the 1850s to the early 1900s, farmers relied heavily on manual labor and practiced subsistence farming. Agriculture was the backbone of the economy, so innovations in farming were crucial for improving yields and feeding a growing population. The transition from hand power to horses was the most significant step in this revolution. However, by 1850, about 70-90 labor-hours were still needed to produce 100 bushels of corn.

Industrial revolution

In the early 20th century, the introduction of tractors and other motorized machinery made farming much more efficient and productive. With these technological advances, farmers were able to cover more land and produce crops using less manual labor, which helped meet the growing demand for food in the United States.

Sustainable farming

To decrease chemical applications and farming's impact on the environment, farmers began adopting natural pesticides and sustainable farming practices like crop rotation and planting cover crops. They started this practice in the 1980s, which also coincided with the introduction of GMOs (genetically modified organisms). This helped farmers grow more food using less water, land and pesticides.

The present and future of farming

As technological advances have made farming more efficient, the focus has shifted to making land use more environmentally friendly. Practices like less intensive tilling and carbon farming have become increasingly popular ways to store and limit greenhouse gas emissions.

Today, agricultural land use in the U.S. is the most diverse it has ever been. For example, approximately one third of the U.S. corn crop (5 billion bushels) is used to create ethanol. Biodiesel is another clean-burning fuel in high demand, and it’s made in part from soybeans. However, these aren’t the only renewable energy products that come from our farms. Agriculture partners are also helping to expand the base of energy production by leasing their land for wind and solar projects.

That might sound like it could reduce the capacity for food production; however, a recent study from Clean Wisconsin found that solar farms can produce more energy on significantly less land and at a lower cost than growing corn for fuel. The study also found that solar farms can meet the state’s future energy needs with as little as 3% of the state’s agricultural land, so there’s plenty of land available for both.

With farmers' focus shifting to environmentally friendly farming practices and the adoption of renewable energy, the future of land use in the United States looks bright. As we continue accelerating our transition to renewables, we are also focusing on contributing to a thriving agricultural community that benefits all and preserves the land for future generations of farmers.
