Crop rotation: This is when farmers alternate the types of crops they grow in a specific area over time. For example, one year they may plant corn, and the next year they may plant beans. This helps maintain soil fertility and prevent disease.
Subsistence agriculture: Similar to traditional subsistence farming, this term refers to agricultural practices aimed at producing enough food for immediate consumption by the farmer's family or community.
Agricultural surplus: This refers to an excess amount of agricultural products (crops or livestock) that can be sold or traded beyond what is needed for immediate consumption.
