What you need to know about the Pennsylvania agriculture revolution

It’s the second agricultural revolution in the United States and the third agricultural revolution to hit the state in the last 100 years.

The Pennsylvania Agricultural Revolution was sparked in the late 19th century by the rise of the American cotton boom.

Today, farmers across the country are trying to replicate the success of Pennsylvania’s farmers.

The revolution has been accompanied by a major economic boom.

In recent years, the U.S. economy has boomed, creating millions of jobs, boosting the state’s gross domestic product by more than $3 trillion and spurring the expansion of the middle class.

But the success story has been tempered by concerns about environmental issues and the lingering effects of the Great Depression.
