Does your pasture need help?

Fertilization Weed control Proper

management Renovation

USU, Logan, UT

Definitions

Establishment - planting a pasture where there is no existing pasture

Renovation - series of actions that lead to a long-term change in the botanical composition of a pasture Partial renovation Total renovation

Type of renovation

Partial renovation Rejuvenation or enhancement of existing

pasture Generally done when poor forage stands

result from winter injury, drought, flooding, or other stresses

Total renovation Destruction followed by reestablishment of

either the same species or another species

Definitions

Species - refers to the type of plant such as alfalfa, sweet clover, smooth bromegrass, etc.

Cultivar - refers to a specific variety within a specie. York, Saratoga, and Bravo are all improved varieties of smooth bromegrass.

Benefits of renovation

Replaces old or diseased pasture species with healthy improved varieties

Extends or increases productivity of pasture

Improves quality of forage Increases animal

productivity Reduces soil erosion Reduces pollution potential

When to renovate?

Renovate when: Pasture is in poor condition and even

proper management techniques will not improve pasture to desired level

You want to grow a different forage specie or variety

Seedbed preparation

Goal - Control weeds and provide a firm seedbed with just enough loose surface soil for shallow seed placement and good seed-to-soil contact

Seedbed preparation

Seed requirements Minimal soil temperature Moisture Oxygen Seed-to-soil contact Accomplish by creating a firm, moist

seedbed

Seedbed preparation

Importance of a firm, moist seedbed

Essential for: Proper seed placement Good soil-seed contact Successful establishment

Seedbed preparation

Deep tillage (plow) Disc Roller harrow or

cultipacker

Creating a firm seedbed takes proper tillage

Seedbed preparation

Purpose of tillage Eliminate existing

vegetation Turn under surface

weed seeds Loosen soil Incorporate fertilizer

and lime Provide firm seedbed

for seeding

Seeding guidelines

Planting dates Seeding depth Inoculation of legumes Why forage seedings fail

www.farmphoto.com

Seeding guidelines

Planting dates Late winter - early spring Late summer - early fall

               

Planting dates

Late winter- early spring seeding Late February to early May More common in northern U.S. Soil moisture usually good If too early soil can be cold, resulting

in fungal diseases If too late, soil can be dry and

seedlings desiccate

Planting dates

Late summer - early fall seeding August to mid-October Less competition from weeds Liming, fertilization, and tillage done during

drier weather thereby reducing compaction Fungal diseases reduced

Note: Seedlings need to have at least six weeks of growth before killing frost

Seeding guidelines

Seeding depth Approximately ¼ inch Varies with:

Soil type Soil moisture Time of seeding Firmness of seedbed

clay.agr.okstate.edu

Seeding guidelines

Inoculation of legumes All legumes should be

inoculated with the proper strains of N-fixing bacteria prior to seeding

Ensures that proper bacteria will be present for nitrogen fixation

Seeding methods Broadcast Cultipacker Drilled No-Till Frost seeding Companion crop USU

Broadcast seeding

Cheapest and easiest method of seeding

Typically drag or pack the soil after broadcasting the seed

Tilled seedbed Seed placement

not uniform

www.modernforage.com

Cultipacker seeding Consists of 2 sets of rollers with seed

boxes between them Commonly used on tilled seedbeds Don’t use on heavy soils

www.faivre.com www.faivre.com

Drill seeding

Directly plants each seed into tilled soil at the proper depth

Need to use a forage drill

Grain drills will have poor seed placement for small forage seeds

UNCE, Reno, NV

No-till seeding

Plants seed directly into existing sod or vegetation Solid planting Band planting

Requires a no-till planter Reduces erosion Conserves soil moisture Reduced fuel, labor, and time

requirements

www.usda.gov

Frost seeding

Seed broadcast in late winter on soil surface

Freezing & thawing action plus rain will cover seed

Works well with Red Clover

Companion crop seedingA companion crop is a small grain crop (i.e. oats) planted with spring-seeded grasses and legumes.

Advantages: Can be cut or grazed for feed Provides a quick ground cover Helps control soil erosion Reduces invasion of weeds

Disadvantages: Competes for nutrients, light, & moisture Good management essential

Forage use

Grazing vs. hay production Determine primary use Many forages that are good for hay

production are not good for grazing, and vice-versa. Upright growth habit - better for hay

production Trampling effects

Forage use: Continuous grazing vs. rotational grazing

Should I plant a mixture?

Advantages Higher yields Legumes fix nitrogen, reducing the

need for nitrogen fertilizer in grasses

Tolerate wider differences in soil conditions

More competitive against weeds

Should I plant a mixture?

Disadvantages Grazing management more

difficult, especially if growth habits not similar

If not managed properly grasses will dominate

Weeds more difficult to control
