Alfalfa is a deep-rooted perennial legume considered the "queen of forage crops" for its high protein content and yield. It fixes 150-250 lb of nitrogen per acre annually and can produce 3-6 cuttings per year in favorable climates. Alfalfa requires well-drained soils with a pH of 6.5-7.5 and does not tolerate standing water. It establishes slowly but persists for 4-8 years once established. Inoculation with Rhizobium bacteria is essential. Plant in spring or late summer into a firm, weed-free seedbed.

How to Calculate Square Feet
Rectangle or Square
Square Feet = Length × Width
Example: 20 ft × 30 ft = 600 sq ft
Example: 20 ft × 30 ft = 600 sq ft
Circle
Square Feet = 3.14 × Radius × Radius
Example: radius 10 ft = 3.14 × 10 × 10 = 314 sq ft
Example: radius 10 ft = 3.14 × 10 × 10 = 314 sq ft
