Which advancement lead to agricultural revolution?

✭ The United States' Agricultural Revolution was a period of U.S. history where major advances in agriculture were occurring. There was a rapid increase in agricultural productivity as well as massive improvements in farming technologies. This revolution took place around the same time as the American Industrial Revolution. However, the Industrial Revolution mainly took place in the Northern states, which the Agricultural Revolution too place in Southern and Western states. It was the first time that farmers began using inventions that were purchased outside of their farm. They began using fertilizers to help their crops grow larger and more efficiently. They also fed their animals artificial preservatives. Because of all this new technology, the time between the 1830s and 1870s became known as the Second Agricultural Revolution.

✭ Many farmers were not only beginning to use these new technologies, but they were also finding them more efficient. It took less time for them to plant and harvest, yet they had more crops than they had before. The new inventions of this era had opened new windows of opportunity for many farmers, and those who bought from the farmers as well. Major products that were being grown during this time were cotton and wheat. With the help of the modern technology, farmers were making more money off of these crops, and they were flourishing.
