winter wheat cover crop

Wheat is a plentiful source of straw and stubble. Managing Cover Crops Profitably explores how and why cover crops work, and provides all the information needed to build cover crops into any farming operation. Benefits and Concerns Nutrient Management. If wheat diseases or pests are a major concern in your area, rye or barley might be a better choice as an overwintering cover crop that provides a grain option, despite their lower grain yield. When it is well-established, winter wheat can tolerate cold to 25 degrees below zero Fahrenheit and prefers medium-rich loam soil. About 80 percent of the K is recycled if the stems and leaves aren’t removed from the field at harvest. “I only chisel plow wheat if it’s really rank,” he notes. Winter Rye. Some starter N (50 to 60 lb./A) can help the wheat establish. In the Corn Belt and northern U.S., undersow red clover or frostseed sweetclover into a wheat nurse crop if you want the option of a year of hay before going back to corn. After drilling wheat, Carter goes back and mows the cotton stalks to leave some field residue until the wheat establishes. Although it generally produces less than rye or barley, the residue can be easier to manage and incorporate. With no till, field pea grown as a cover crop before winter wheat allowed to reach grain yield similar to those observed in the tilled treatments. “It’s easier to manage than rye, still leaves plenty of residue to keep topsoil from washing away—and is an excellent double crop,” says Carter. Based in the College of Agriculture and Life Sciences, we reach millions of North Carolina citizens each year through local centers in the state's 100 counties and with the Eastern Band of Cherokee Indians. Hard winter wheat, Austrian winter peas, and tillage radish make good sisters. In Colorado vegetable systems, wheat reduced wind erosion and scavenged N from 5 feet deep in the profile (111, 114). “You want a good, competitive wheat stand and a vigorous potato crop if you’re depending on a banded herbicide mix and wheat mulch for weed control,” says Eberlein. It is increasingly grown instead of rye because it is cheaper and easier to manage in spring. In much of Zone 7, cowpeas would be a good choice after wheat harvest in early July or before planting winter wheat in fall.

To plant winter wheat as cover crop, rake the garden smooth, removing debris and large rocks. Adequate but not excessive N is important during wheat’s early growth stages (prior to stem growth) to ensure adequate tillering and root growth prior to winter dormancy. “Adding wheat and a cover crop can make the difference over time when faced with less than ideal conditions,” she explains. Normally we think about cover crops for fall planting, but there are also options to plant cover crops in March/April. That would defeat the primary purpose (N scavenging) of growing a small grain cover crop. Cover crops are used for a wide variety of reasons, from green manure to soil improvement to weed control. The foliage is pale green and the flowers are purple, pink or reddish. They also contribute to the reduction of mineral leaching and compaction , suppress the amount of weed growth, reduce insect pests and diseases, and increase crop yield. “In our initial study, we were effectively no-tilling potatoes into the Roundup-killed wheat,” says Eberlein. At the 2018 Wheat Field Day at the Princeton Research and Education Center, Dr. Erin Haramoto presented Using Wheat as a Cover Crop. The southeastern Georgia farmer no-till drills winter wheat at 2 bushels per acre right after cotton harvest, without any seedbed preparation. The discussion around adding winter wheat and a cover crop into a rotation to build soils and improve the bottom line is supported by concrete evidence, but some growers continue to resist the recommendation. The wheat goes to seed slower and can provide more biomass than an earlier killing of rye would, he’s found. Plant this hardy annual cereal grain from seeds, which are available at farm suppliers, online and some garden centers. Native to southwest Asia, winter wheat planting was first introduced by Russian Mennonites during the 19th century. If indicated by soil testing, P or K also would be fall-applied for the following potato crop. This hardy annual cereal grain provides a host of benefits to compacted and overused soil. The thick, lush growth protects the soil from winter’s fury. Diseases can be more of a problem the earlier wheat is planted in fall, especially if you farm in a humid area. Banding herbicide over the row when planting potatoes improved the system’s effectiveness, subsequent research shows, says project coordinator Dr. Charlotte Eberlein at the University of Idaho’s Aberdeen Research and Extension Center. Winter wheat is grown as a cash crop or a cover crop.Optimal growing conditions for winter wheat include high-drainage soil with medium texture. An irrigation option ensures adequate soil moisture—for the wheat stand in fall or the potato crop in spring, she adds. N/A by December, a Maryland study showed (46). Without a living cover crop growing through the winter and into the spring, nitrogen scavenging and nitrogen fixation cease, and the opportunity to grow more cover crop biomass to build organic matter is lost. A September-seeded stand absorbed 40 lb. Winter wheat makes a good grain for use as a overwintering cover crop Using Cover Crops to Improve Drainage. Having winter-hardy species in the mixture will help to maintain cover crop benefits throughout the winter and into the spring. “If you have sandy soil to start with and can kill winter wheat early enough to reduce water-management concerns for the potatoes, the system works well,” says Eberlein. Nitrogen uptake is only half of that of rye in the fall It builds soil and encourages helpful soil microorganisms. If weed control is important in your system, look for a regional cultivar that can produce early spring growth. The 100 days between winter wheat harvest and winter wheat planting are a fine time to grow short-season cover crop blends, according to Windom, Kansas, farmer Joe Swanson. See Wheat Boosts Income and Soil Protection. Soil builder and organic matter source. Also in Maryland, wheat produced up to 12,500 lb. If you sow sweetclover in fall with winter wheat, it could outgrow the wheat. And that protection extends to keeping weed seeds out as well. In regions where these crops survive winter, they will grow vigorously in early spring. In this study we killed the cover crop and planted potatoes with a regular potato planter, which rips the wheat out of the potato row, a grower then can band a herbicide mixture over the row and depend on the wheat mulch to control between-row weeds. Oats and spring barley will grow rapidly in late summer and continue until a hard freeze. Winter wheat can be grown as a cash crop or a cover crop, although you should manage each differently. Learn how to grow winter wheat to improve soil conditions, repair exposed areas and minimize erosion. It provides a cash-grain option while also opening a spot for a winter annual legume in a corn>soybean or similar rotation. Erosion control. When red winter wheat is baled solely as a cover crop to add more nutrients back into the soil, simply till the crop under in the spring once the ground is no longer too frozen and hard to complete the task. The root of the wheat houses the most nutrient-rich compounds. SARE Outreach operates under cooperative agreements with the University of Maryland to develop and disseminate information about sustainable agriculture. Prolific salads such as mache or corn salad may also be grown this way. There are many herbicides registered for use in wheat but good weed control for a cover crop should not be expensive and may not be needed.
