Farming changed a lot in Britain. This was called the British Agricultural Revolution. 

The British Agricultural Revolution was a time of huge change in farming. It happened between the mid-1600s and the late 1800s. During this time, farmers learned to grow much more food on the same amount of land. 
Farmers used new methods to keep their soil healthy and strong. One major way was through a process called crop rotation. This means planting different types of crops in a specific order. 
New tools and ways of managing land also helped a lot. Farmers used new machines like the seed drill to plant crops. They also used a better version of the heavy iron plough. This plough was adapted from designs used in China. 
These changes happened in many different places around the world. While many call it the British revolution, it happened elsewhere too. In the Netherlands, farmers saw huge growth even earlier than in Britain. In the United States, production of wheat and corn grew very fast between 1860 and 1890. 
The Agricultural Revolution changed how the whole world worked. Because farmers could grow more food with fewer workers, many people moved to cities. This provided the workers needed for the Industrial Revolution. 
The British Agricultural Revolution refers to a period of massive growth in food production. This change occurred between the mid-17th century and the late 19th century. It involved much higher productivity from both land and labor. This means farmers grew more food using the same amount of space and fewer workers. Many historians view this as an essential foundation for the Industrial Revolution. Because fewer people were needed on farms, they could move to cities to work in factories. This shift provided the large workforce required for modern industry to grow.
One of the most important changes was the shift in crop rotation. In the Middle Ages, farmers often used a two-field or three-field system. In these systems, a portion of the land was left fallow. Fallow land is ground that is left unplanted to let the soil rest. This was necessary to prevent nutrients from being completely used up. However, leaving land empty meant less food could be grown. The Norfolk four-course system changed this by using different crops in a specific sequence. 
These specific crops worked in different ways to help the soil. Turnips are deep-rooted plants that can be grown in the winter. Their long roots reach deep into the earth to gather nutrients that shallow crops cannot reach. Clover is a legume, which is a type of plant that performs a special task. Clover has bacteria on its roots that can fix nitrogen from the atmosphere. This process turns nitrogen into a natural fertilizer that stays in the soil. By rotating these crops, farmers could keep the soil fertile without leaving it empty. This allowed for much more intensive farming on light soils.
Technological innovations also played a major role in this period. Farmers began using new machinery to make work more efficient. One example was the seed drill, which helped plant seeds more accurately. They also used an adapted version of the heavy, mould-board iron plough. This tool was based on designs from China and was easier to pull. It required fewer oxen or horses to move through the dirt. 
Changes in how land was managed and moved also occurred. A process called enclosure involved removing common rights to land. This allowed individuals to establish exclusive ownership over specific plots. Enclosure made it easier for farmers to try new methods without interference. At the same time, transportation infrastructure improved significantly. New roads, canals, and eventually railways were built to move goods. A national market also developed because barriers like tariffs and tolls were removed. This made it easier to sell food across the entire country.
These changes had a massive impact on the human population. In England and Wales, the population grew from 5.5 million in 1700 to over 9 million by 1801. By the 19th century, the population reached over 35 million. Between 1700 and 1850, the productivity of each individual laborer increased by a factor of 2.5. This massive increase in food helped support more and more people. While domestic production was high, the country eventually began importing more food as the population continued to rise. 
While the term "British" is common, these changes were not limited to Britain. The Netherlands saw huge growth even earlier, between 1500 and 1650. In the Netherlands, agricultural output per laborer rose by 80% during that time. Many British landowners even adopted Dutch methods and techniques. Similar patterns appeared in other parts of the world as well. In Russia, cereal yields increased by 48% between 1867 and 1915. In the United States, the production of wheat, corn, and cotton grew rapidly between 1860 and 1890.
