Alfalfa is a perennial forage crop of high agronomic value, appreciated for its high protein content and excellent regrowth capacity. It adapts well to temperate climates and deep soils with good drainage and a neutral or slightly alkaline pH. It stands out for its taproot system, which improves soil structure and promotes biological nitrogen fixation, reducing the need for external nitrogen inputs. Proper management requires effective weed control during establishment, a cutting schedule that preserves forage quality, and fertilization focused on phosphorus, potassium, and essential micronutrients. Thanks to its productivity, stability, and nutritional value, alfalfa is a key component in both intensive and extensive livestock systems.
