     to cover seed, as this will place seed too deep to

    emerge. It is advisable to use the no-till method of

    seeding, as opposed to disking and ripping the soil

    first. Disturbing the soil can bring up unwanted

    plant species. Dryland pastures are seeded in the

    fall; prior to the occurrence of heavy winter rains.

    Seeding early in the fall allows plants to grow while

    temperatures are relatively warm and also reduces

    erosion hazards from high intensity rains. Long-

    range weather records show that the most

    favorable period to seed is from October 1 to

    October 15.

Fewer pounds of seeds per acre are needed on an established pasture. When to Plant Inoculation of sub clovers is crucial in establishing Dryland pastures are seeded in the fall; prior to the a good stand of clover. Only accept clovers that occurrence of heavy winter rains. Seeding early in have been inoculated within the last two months. the fall allows plants to grow while temperatures Inoculating the clovers yourself, assures higher are relatively warm and also reduces erosion counts of effective rhizobium, which means greater hazards from high intensity rains. Long-range success. weather records show that the most favorable period to seed is from October 1 to October 31. Types of Fertilizer to Use Nearly all of our range and pasturelands are How to Seed a Pasture deficient in nitrogen and phosphorous, and some Mix the various seed before broadcasting. Small acres are also deficient in sulfur. Properly acreages, up to ten acres, can be seeded using a inoculated sub clover should fix 40-50 lbs. of broadcast seeder by hand. This type of seeder will nitrogen per acre on a yearly basis, which can be normally broadcast seed over a 15 to 20 foot wide used by the grasses. The use of 200 lbs. per acre swath. Each swath should overlap so that of 0-45-0-2 (treble super phosphate) or 150-200 distribution is uniform. lbs. per acre of 11-52-0-2 (mono-ammonium phosphate) at the time of planting will supply The broad casted seed should then be covered by a adequate phosphorous and sulfur needed for the ? inch of soil. This may be accomplished by ring clovers. If only grasses are planted and/or rolling, or by using a spike tooth harrow with the nitrogen and phosphorus. How often fertilization is teeth sloped at a 45-degree angle.

If subterranean clovers are shaded by the grasses early in growth, they will not grow properly and could be lost. Yields from a newly seeded pasture Handout revised: 10/2009 will be approximately 60 percent of future yield.

    An important part of grazing management is implementing a controlled rotation grazing system that allows plants to rest and re-grow. Pastures should be managed to maintain animal health requirements while maintaining the needs of a new pasture.

What Type of Soil is Required?

    Most soils that are 18 to 24 inches deep will grow satisfactory dryland pastures. Soils less than 18 inches deep will produce less forage because the soil moisture is exhausted sooner following the last spring rains.

Use of Supplemental Feed on Pasture

    Supplemental feeding during certain periods will increase the utilization of the forage produced. Alfalfa hay, oat hay, or other appropriate food sources fed during the winter and summer months, may be necessary to need the nutritional requirements of livestock.

Quality of Forage from Pasture

    The quality of forage produced is superior to most of native pastures. Sub clover has a high percent of crude protein when green and will contain up to 12 percent crude protein in the mature, dry stage.

Acres Needed per Animal Unit

    An animal unit is a 1,000 pound animal and usually a horse is equivalent to 1.4 animal unit. An animal will consume approximately 2 3 % of

    its body weight per day, depending on its nutritional requirements. Therefore, on average, a horse will require 1,050 pounds of forage per month or six tons of hay or its forage equivalent on a yearly basis. Depending on the management of the pastures, an acre of irrigated pasture can produce enough forage to carry one horse for the entire year.
