Conventional: dominant farming practice in a region, in technology driven regions, this includes. Genetics/chemicals: heavy input style, generally produces more. Sustainable: strives to view agriculture as an entire system, manages natural resources instead of purchasing and applying inputs, also known as: Early agronomic practices: domestication of plants. Began in the fertile crescent in 8000 bc. Began with wild barley, emmer, and einkhorn wheat: irrigation. Began in the fertile crescent in 5000 bc: hand tools. Began in egypt in 3500 bc: crop rotations. Began in the roman empire in 200 ad: terraces. Andean terraces: ag crops on steep slopes (rome) Results: growth on steep slopes, efficient water use due to gravitational drainage, rock walls that compose the terrace heat the ground longer, prevent temperature fluctuations. Modern agronomic practices: mechanization (hand tools tractors, synthetic fertilizers (~1910)
