Agricultural systems refer to the various methods and practices used to cultivate crops and raise livestock. These systems can vary widely based on factors such as climate, soil type, and available technology. Common types include conventional agriculture, which relies on chemical fertilizers and pesticides, and organic farming, which emphasizes natural processes and sustainability. In addition to crop production, agricultural systems also encompass agroforestry, which integrates trees and shrubs into farming, and permaculture, a design philosophy that seeks to create sustainable and self-sufficient agricultural ecosystems. Each system aims to optimize food production while considering environmental impacts.
