This builds off of the previous section, which focused on the evolution of agriculture overtime and the diffusion agricultural practices. The Second Agricultural Revolution was a major turning point in agriculture, so you should focus on the major advancements and significant impacts that it had on agricultural techniques. 
Now let’s dig deeper: 
The Second Agricultural Revolution was huge! It all started in England, around the 1600s and lasted until the late 1800s, where it soon spread to Europe, North America, and eventually other parts of the world. New agricultural techniques, such as new crop rotation methods and selective livestock breeding were introduced which led to a great big increase in food production. The Industrial Revolution and a surge in population occurred around the same period as the Second Agricultural Revolution, with the introduction of new technologies benefiting the Second Agricultural Revolution. 
*Important to note that it diffused hierarchically.
In short…
