The second agricultural revolution is generally said to have occurred along with the Industrial Revolution. It came about in part because of the Industrial Revolution and it helped allow the Industrial Revolution to happen. The second agricultural revolution was based on a greater use of technology. It happened in the 1800´s. In the second agricultural revolution farming really changed from using hard labor to using machines to do all the work.
The third agricultural Revolution was a period in time when new agricultural practices were created to help farmers all over the world. It was an international effort that was planned to eliminate hunger by improving crop performances. This plan provided new practices that allowed farmers to produce more of the same product within the same amount of land. This meant that the farmers could get more out of their land than they used to. This rapid diffusion of more productive agriculture techniques occurred throughout the 1970s and the 1980s. The plan had two main practices, the introduction of newer higher-yield seeds and the expanded use of fertilizers. This would lead to the increase of the agricultural productivity at a global scale, which increased faster than population growth. The third agricultural revolution answered questions from experts about massive global famine
When a gene from one organism is purposely moved to improve or change another organism in a laboratory, the result is a genetically modified organism. It is also sometimes called "transgenic" for transfer of genes. There are different ways of moving genes to produce desirable traits.
Commercial farming is typically done on a very large scale, often by agricultural corporations. The goal of commercial farming is to make profits, which is done through maximizing crop yields through labor-saving techniques and technology. In subsistence farming, farmers grow a wider range of crops based on the anticipated needs of their families or communities. Traditionally, subsistence farmers have eaten what they grow.
