Purpose of Study to Evaluation Clover Frost Seed Into Cool Season Grasses vs. no Clover • Cool Season Grass Paddocks were established in August, 2002. • Study to show important of nitrogen provide by clover vs. commercial nitrogen.

Ampac Paddocks • Quartet Perennial Ryegrass 7.5 lbs • Due Festuolium 7.5 lbs • Tekapo Orchardgrass 15 lbs • Starfire Red Clover 4 lbs* • Kopu White Clover 2 lbs* • * Clover were seed in March, 2003
Barenbrug Paddocks • Baradan Orchardgrass 11.25 lbs • Barcel Tall Fescue 14.75 lbs • Alice White Clover 2 lbs* • Freedom Red Clover 5 lbs* • Clover Seed March 2003
Pennington Paddocks • Max Q Tall Fescue 20 lbs • Patriot White Clover 3 lbs* • White Clover Seeded March, 2003
Frost Seeding of Clover • For the Ampac and Barenbrug Paddocks • 5 lbs Red Clove and 2 lbs White Clover frost seed in March each year. • For Pennington Paddocks 2 lbs White Clover frost seeded in March each year.
Percent Clover in Stand • When study begin in spring of 2008 the stands consisted of 60 percent cool season grasses and 40 percent clovers by dry matter content in all paddocks. Half of paddocks continue to receive clovers frost seeded annually and one half of paddocks received no clovers for 4 years from 2008 to 2011.

Advantages of Mixtures of Cool Season Grasses and Clovers • Legumes provide nitrogen for grasses • Legumes improve forage quality and reduce the potential for nitrate poisoning • The fibrous root system of grass helps in stabilizing slopes and reducing erosion • The stand life of forages is lengthended • Grasses reduce bloat potential when included with legumes
Clovers are generally higher in the following nutrients than grasses • Crude Protein • TDN • Calcium • Magnesium • Clovers maintain much higher levels of magnesium than grasses on wet soils in spring, reducing potential for cattle losses from tetany.

Frost Seeding • Frost seeding legumes and grasses is increasingly being used by producers as a means to improve pasture yields or change forage species composition within the pasture.
Keys to successful frost seedings • 1. Seed to soil contact • 2. Reduce plant competition with new seedlings • 3. Species selection and seeding rates • 4. Seeding time
Frost seeding pitfalls • 1. Seed planted into sod too tall. • 2. Legumes seeds not inoculated. • 3. Competition by taller grass. • 4. Poor soil fertility.
Summary: Benefits of Clovers • 1. Improved Quality • 2. Nitrogen Fixation • 3. Higher Yields • 4. Extend Summer Growth
Summary # 2: Cost of Clovers vs Commercial Fertilizers • The Cost for frost seeding clovers has ranged from$20 to $30 per year. • The cost for commercial nitrogen applied at 100 lbs. actual nitrogen per acre would range from $55 to $75 plus application cost per year.
