First Agricultural Revolution
Dating back 10,000 years, the First Agricultural Revolution achieved plant domestication and animal domestication
genetic modification of a plant such that its reproductive success depends on human intervention
Second Agricultural Revolution
tools and equipment were modified, methods of soil preparation, fertilization, crop care, and harvesting improved the general organization of agriculture made more efficient
a form of subsistence agriculture in which people shift activity from one field to another; each field is used for crops for a relatively few years and left uncultivated for a relatively long period
farming that provides for the basic needs of the farmer without surpluses for marketing
