Alfalfa, a highly nutritious and versatile forage crop, is widely used in pasture systems for livestock production. Its high protein content, palatability, and ability to adapt to various soil conditions make it an ideal pasture for cattle, sheep, and horses. This comprehensive guide will provide you with detailed instructions on how to grow alfalfa pasture successfully.
Site Selection and Soil Preparation
Site Selection: Choose a well-drained site with a pH between 6.5 and 7.5. Alfalfa prefers deep, fertile soils with good water-holding capacity. Avoid areas with poor drainage or excessive acidity.
Soil Preparation: Test the soil to determine its fertility and pH. Amend the soil with lime if the pH is below 6.5. Incorporate organic matter, such as manure or compost, to improve soil structure and fertility.
Alfalfa Varieties
Select alfalfa varieties that are well-suited to your climate and intended use. There are numerous varieties available, each with its own advantages and disadvantages. Consider factors such as yield potential, disease resistance, and winterhardiness when choosing a variety.
Seeding and Establishment
Seeding Rate: The recommended seeding rate for alfalfa is 20-25 pounds per acre.
Seeding Depth: Plant alfalfa seeds at a depth of 1/4 to 1/2 inch.
Seeding Time: The best time to seed alfalfa is in the spring or early fall when soil temperatures are warm enough for germination.
Irrigation and Fertilization
Irrigation: Alfalfa requires regular irrigation, especially during hot, dry weather. Water deeply and infrequently to encourage deep root development.
Fertilization: Fertilize alfalfa annually with phosphorus and potassium according to soil test recommendations. Nitrogen fertilization is generally not necessary, as alfalfa can fix nitrogen from the air.
Weed Control
Pre-emergent Herbicides: Apply pre-emergent herbicides to control weeds that emerge from seeds.
Post-emergent Herbicides: Use post-emergent herbicides to control established weeds. Follow herbicide label instructions carefully to avoid damage to alfalfa plants.
Pest and Disease Management
Aphids: Aphids can transmit diseases and cause damage to alfalfa plants. Control aphids with insecticidal soap or neem oil.
Weevils: Weevils can damage alfalfa stems and leaves. Control weevils with insecticides or biological controls.
Bacterial Wilt: Bacterial wilt is a serious disease that can kill alfalfa plants. Use disease-resistant varieties and practice good sanitation to prevent the spread of the disease.
Grazing Management
Grazing Rotation: Rotate livestock on alfalfa pastures to allow for plant recovery.
Grazing Height: Maintain a grazing height of 4-6 inches to promote healthy plant growth and prevent damage to crowns.
Harvest and Storage
Harvesting: Alfalfa can be harvested as hay, silage, or green chop. Harvest when plants are in the bud stage for optimal quality.
Storage: Store alfalfa hay in a dry, well-ventilated area to prevent spoilage.
Final Thoughts
Growing alfalfa pasture can be a rewarding experience for livestock producers. By following the steps outlined in this guide, you can establish and maintain a thriving alfalfa pasture that provides high-quality forage for your animals. Remember to regularly monitor your pasture for pests, diseases, and weeds, and adjust management practices as needed. With proper care and attention, your alfalfa pasture will thrive and provide a valuable source of nutrition for your livestock for years to come.
