AvatarBySheryl Ackerman Uncategorized

When it comes to establishing a thriving clover stand, one of the most common questions farmers and gardeners ask is, “How much clover should I plant per acre?” Whether you’re aiming to improve soil health, provide nutritious forage for livestock, or enhance your pasture’s biodiversity, getting the right seeding rate is crucial. Planting too little clover can lead to poor coverage and competition from weeds, while planting too much might be an unnecessary expense and could affect the balance of your pasture ecosystem.

Understanding the appropriate amount of clover seed to sow per acre involves considering several factors, including the type of clover, soil conditions, and your specific agricultural goals. Different clover varieties have varying seed sizes and growth habits, which influence how densely they should be planted. Additionally, environmental conditions and management practices play a role in determining the optimal seeding rate to ensure a healthy, productive stand.

This article will guide you through the essentials of clover planting rates, helping you make informed decisions tailored to your land and objectives. By exploring key considerations and best practices, you’ll be better equipped to maximize the benefits of clover in your fields and pastures.

Recommended Clover Seeding Rates per Acre

Determining the appropriate amount of clover seed to plant per acre depends on several factors, including the clover species, soil fertility, intended use (forage, cover crop, or soil improvement), and whether the clover is being planted alone or in a mixture with grasses or other legumes.

For pure stands of clover, seeding rates are generally higher, while lower rates are used when clover is overseeded into existing pastures or mixed with grasses. The seed size, germination rate, and seed purity also influence the effective seeding rate.

Below are typical seeding rates for common clover species when planted alone:

  • Red Clover: 8 to 12 pounds per acre
  • White Clover: 2 to 4 pounds per acre
  • Alsike Clover: 5 to 8 pounds per acre
  • Crimson Clover: 15 to 20 pounds per acre
  • Sweet Clover: 3 to 5 pounds per acre

Factors Affecting Clover Seeding Rate

Several key factors must be considered to adjust the seeding rate appropriately:

  • Seed Purity and Germination: Seed labels often provide purity and germination percentages. Adjust the seeding rate by dividing the desired pure live seed rate by the decimal equivalent of purity and germination.
  • Soil Fertility and pH: Clover thrives in well-drained soils with pH between 6.0 and 7.0. Lower fertility or pH may reduce stand establishment, sometimes warranting increased seeding rates.
  • Planting Method: Drill seeding typically requires less seed than broadcast seeding due to better seed-to-soil contact.
  • Mixture or Pure Stand: When planting clover with grasses, reduce the clover seeding rate to avoid excessive competition or dominance.

Adjusting Seeding Rates Based on Seed Quality

To ensure the correct amount of viable seed is planted, calculate the Pure Live Seed (PLS) rate. PLS accounts for both seed purity and germination percentage.

The formula is:

Seeding Rate (bulk seed) = Desired PLS rate ÷ (Purity × Germination)

For example, if the desired PLS rate for red clover is 10 pounds per acre, seed purity is 90%, and germination is 85%, the bulk seed rate is:

Bulk Seed Rate = 10 ÷ (0.90 × 0.85) = 10 ÷ 0.765 = 13.07 pounds per acre

This means you need to purchase approximately 13 pounds of seed per acre to achieve 10 pounds of viable seed.

Typical Clover Seeding Rates Table

Clover Species Pure Live Seed Rate (lbs/acre) Bulk Seed Rate Range (lbs/acre)
(Assuming 90% purity, 85% germination)		 Common Use
Red Clover 8 – 12 10 – 16 Forage, soil improvement
White Clover 2 – 4 3 – 5.5 Pasture, erosion control
Alsike Clover 5 – 8 6 – 11 Forage, wet soils
Crimson Clover 15 – 20 18 – 26 Cover crop, forage
Sweet Clover 3 – 5 4 – 7 Soil improvement, forage

Seeding Rate Recommendations for Mixed Plantings

When clover is seeded in combination with grasses or other legumes, reduce the clover seeding rate to avoid excessive competition and to balance plant populations. A typical adjustment is to plant 50–75% of the pure stand seeding rate for clover.

For example:

  • If red clover pure stand rate is 10 lbs/acre, use 5 to 7.5 lbs/acre when mixed with grasses.
  • For white clover, reduce from 3 lbs/acre pure stand rate to approximately 1.5 to 2 lbs/acre in mixtures.

This approach helps maintain a balanced sward and prevents clover from overwhelming other species.

Additional Considerations for Clover Planting

  • Planting Depth: Clover seeds are small and should be planted shallowly, typically ¼ to ½ inch deep, to ensure good emergence.
  • Planting Time: Timing depends on species and climate. For instance, red clover is often planted in early spring or late summer, while crimson clover prefers fall planting.
  • Seedbed Preparation: Prepare a firm, weed-free seedbed to maximize seed-to-soil contact and minimize competition from weeds.

Recommended Clover Seeding Rates Per Acre

Determining the appropriate amount of clover to plant per acre depends on the specific clover species, intended use (forage, cover cropping, soil improvement), and planting method. Proper seeding rates ensure optimal stand establishment, maximize nitrogen fixation, and improve soil health without wasting seed or risking overly dense stands.

Below are commonly recommended seeding rates for various types of clover planted per acre:

Clover Type Seeding Rate (lbs/acre) Recommended Planting Method Notes
Red Clover 8 – 12 Broadcast or drilled Often mixed with grasses; does well in well-drained soils
White Clover 2 – 5 Drilled or broadcast Common in pastures; lower seeding rate due to fine seed size
Crimson Clover 15 – 20 Broadcast or drilled Used as winter cover crop; prefers well-prepared seedbed
Sweet Clover (Yellow or White) 10 – 15 Drilled or broadcast Deep-rooted; good for soil improvement and erosion control
Alsike Clover 8 – 10 Drilled or broadcast Prefers wet soils; often used in mixtures with grasses

Factors Influencing Clover Seeding Rates

Several agronomic and environmental factors must be considered when deciding on the clover seeding rate per acre:

  • Seed Purity and Germination Rate: Adjust seeding rates based on seed test results. High purity and germination percentages allow for lower seeding rates.
  • Planting Method: Drilling typically requires lower seeding rates than broadcasting because seed-to-soil contact is better, improving germination.
  • Soil Fertility and pH: Clover thrives in well-drained, fertile soils with pH between 6.0 and 7.0. Poor soil conditions may require adjustments in seeding density or soil amendments.
  • Intended Use: For pasture renovation, higher seeding rates may be necessary to compete with existing vegetation. For cover cropping, moderate rates suffice.
  • Seedbed Preparation: Well-prepared seedbeds enable lower seeding rates due to improved seed-soil contact and moisture retention.
  • Climate and Growing Season Length: Regional climate influences establishment success and may dictate adjustments to seeding rates to ensure rapid coverage.

Adjusting Seeding Rates for Mixed Plantings

Clover is frequently seeded in mixtures with grasses or other legumes to improve pasture quality or soil health. When planting in mixtures, the clover seeding rate per acre should be reduced proportionally to accommodate companion species.

Consider these guidelines when planting clover in mixtures:

  • Reduce the pure clover seeding rate by 25-50% depending on the proportion of clover in the mix.
  • Balance seeding rates to prevent either species from dominating, ensuring complementary growth and resource use.
  • Use compatible species that have similar establishment requirements and growth habits.
  • Consult mixture-specific recommendations for precise seeding ratios.
Mixture Type Clover Seeding Rate (lbs/acre) Companion Species Notes
Red Clover + Orchardgrass 5 – 7 Orchardgrass (10 – 15 lbs/acre) Balances forage quality and persistence
White Clover + Perennial Ryegrass 1.5 – 3 Perennial Ryegrass (10 – 12 lbs/acre) Common pasture mix for grazing systems
Crimson Clover + Small Grains (e.g., Oats) 10 – 15 Oats (30 – 40 lbs/acre) Used for cover cropping and soil improvement
