Which period of agricultural development in the 17th and 18th centuries increased productivity through mechanization and crop rotation?

• A. Second Agricultural Revolution
• B. First Agricultural Revolution (Neolithic)
• C. Green Revolution
• D. Third Agricultural Revolution

Answer: (A)

The period being described is the second Agricultural Revolution, the era when farming productivity rose in the 17th and 18th centuries through a combination of crop rotation and early mechanization. Crop rotation practices, like rotating crops to preserve soil fertility with nitrogen-producing plants such as clover and turnips, kept soils healthier and allowed more crops to be grown over time. Innovations in planting and harvesting—such as the seed drill, which sows seeds at the right depth and spacing, and later steam-powered tools—made farming work faster and with less manual labor. These changes together boosted yields and laid the groundwork for larger, more productive farms and the broader changes that accompanied the Industrial Revolution. By contrast, the first Agricultural Revolution refers to the shift from hunting and gathering to farming in ancient times, while the Green Revolution and the later Third Agricultural Revolution describe 20th-century developments in high-yield crops and biotechnology, not the 17th–18th-century improvements in Europe.
