G93-1158 Questions And Answers About Atrazine, Fred Roeth, S.D. Comfort

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide addresses some of the current concerns about atrazine and water quality. Included are some questions and answers about atrazine regarding toxicity, EPA guidelines, presence in water supplies, weed resistance and best management practices. What is atrazine? Atrazine is a herbicide that selectively controls broadleaf (dicot) weeds, such as pigweed, cocklebur, velvetleaf and certain grass weeds in fields of corn and sorghum. Selective control means that the target weeds are controlled, with little or no injury to the crop. Atrazine is well tolerated by actively growing corn and sorghum, which absorb and metabolize the herbicide and thereby detoxify it.

G91-1010 Managing Corn And Sorghum Residues During The Ecofarming Fallow Period, Robert N. Klein, Gail A. Wicks

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains how to maintain an appropriate residue cover with ecofarming in the fallow period before winter wheat to reduce soil erosion and conserve soil moisture. Ecofarming is a system of controlling weeds and managing crop residues throughout a crop rotation with minimum use of tillage. This will reduce soil erosion and production costs while increasing weed control, water infiltration, moisture conservation and crop yields. In the winter wheat-ecofallow corn or grain sorghum-fallow rotation, corn or grain sorghum is no-till planted into winter wheat stubble in May. During the previous summer or fall the winter wheat stubble was treated …

G91-1009 Getting Started In Ecofarming: Growing The Winter Wheat Crop, Gail A. Wicks, Robert N. Klein, Drew J. Lyon

University of Nebraska-Lincoln Extension: Historical Materials

Cultural practices can improve the weed competitiveness of winter wheat in an ecofallow program, thus increasing the effectiveness of herbicides. Ecofarming is a popular conservation tillage practice used in Nebraska areas where winter wheat is produced. It requires a high degree of management, but the rewards through higher crop yields and erosion protection are worth the effort. In Nebraska the winter wheat-fallow rotation is the common rotation used in areas of less than 17 inches of rainfall, while in areas that receive 17 to 22 inches the winter wheat-corn or sorghum fallow rotation is most common. In 1988, 41 percent …

G88-884 Ecofarming: Selecting Corn And Grain Sorghum Hybrids, Planting Dates, And Planting Rates In A Winter Wheat--Row Crop--Fallow Rotation, Robert N. Klein, Gail A. Wicks, P. T. Nordquist

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses selecting corn and sorghum hybrids, factors that affect yield, plant populations, and more. Treating winter wheat stubble with herbicides after harvest, and then planting corn or grain sorghum in the untilled stubble the next spring, is a practice used for over 15 years in many parts of the Central Great Plains. The residue protects the soil from wind and water erosion. This method of farming is one of the most effective soil and water conservation practices adapted in this century.

G87-835 Ecofarming: No-Till Ecofallow Proso Millet In Winter Wheat Stubble, Robert E. Ramsel, Lenis Alton Nelson, Gail A. Wicks

University of Nebraska-Lincoln Extension: Historical Materials

No-till farming is gaining acceptance in semiarid areas of the Central Great Plains. Proso millet can be planted no-till into wheat stubble. This NebGuide tells you how. No-till farming is rapidly gaining acceptance in semiarid areas of the Central Great Plains. Corn and sorghum are now being no-till planted directly into undisturbed wheat stubble and grown successfully. They are planted the spring following wheat harvest. Proso millet can also be planted no-till into wheat stubble.

G86-809 Ecofarming: No-Till Sorghum Following Ecofallow Corn Or Sorghum, Robert N. Klein, Gail A. Wicks

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes using no-till sorghum in ecofallow rotations, including hybrid selection, planting and weed control methods, fertilizing, and possible insect and disease problems. The ecofarming system using a winter wheat-ecofallow corn or sorghum-fallow rotation has increased corn and sorghum yields because more water is conserved by controlling weeds with herbicides than with tillage. The land is fallowed the year following corn or sorghum and planted to winter wheat in the fall. Often enough precipitation is received during winter and/or early spring that another crop of sorghum could be grown instead of fallowing and planting wheat. If about 2000 lb/A …

G81-551 Ecofarming: Spring Row Crop Planting And Weed Control In Winter Wheat Stubble, Gail A. Wicks, Norman L. Klocke

University of Nebraska-Lincoln Extension: Historical Materials

Weed control, stubble management and planters for planting in winter wheat stubble are covered here.

Planting corn, sorghum or soybeans into untilled, weed-free winter wheat stubble that is 10 months old is an accepted practice in the Central Great Plains States. In Nebraska, this system is known as ecofallow. Treating the stubble with herbicides following wheat harvest (ecofallow) offers several advantages:

Weed and volunteer wheat growth can be eliminated. Weed growth robs valuable moisture that could be used by the next year's crop.

Standing stubble provides an excellent snow trap during the winter. Snow melt can provide moisture for the …

G81-546 Ecofarming: Fallow Aids In Winter Wheat-Fallow Rotation, Gail A. Wicks, Charles R. Fenster

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the use of ecofarming to control weeds and manage crop residues.

Ecofarming is defined as a system of controlling weeds and managing crop residues throughout a crop rotation with minimum use of tillage so as to reduce soil erosion and production costs while increasing weed control, water infiltration, moisture conservation and crop yields. Energy requirements are much lower with ecofallow than with normal fallow systems. The ecofallow period in the 3-year rotation is the period between wheat or other small grain harvest and the planting of corn or sorghum. The fallow period in the 2-year rotation occurs …

G81-550 Ecofarming Operating High Capacity Sprayers (Floaters) For Herbicide Application, Gail A. Wicks, Charles R. Fenster, Norman L. Klocke

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide will help you determine whether you are covered by or exempt from the Worker Protection Standard and provide information on how to comply.

Many flotation sprayers are only used to spray fertilizers and herbicides in the spring. Ecofarming, however, represents a March to November market for them. Successful ecofarming requires precision spraying of herbicides on the winter wheat stubble, and offers tremendous opportunities for professional applicators. Commercial application eliminates some of the field work for the farmer, which is an important element for more efficient farming. The commercial applicator is also able to do a better job since …

G80-500 Ecofarming: Selection Of Tractor Mounted Or Pull-Type Sprayers, Norman L. Klocke, G. A. Wicks, R. Fenster

University of Nebraska-Lincoln Extension: Historical Materials

Uniform application of dependable herbicides in the ecofarming program is a key to its success. A good sprayer is needed to accomplish this, and not every new sprayer available will do the job. The following sprayer components should be checked carefully: pump, tank, tank agitation, flow-control assembly, strainers and screens, distribution system (including boom), and nozzles. Each of the components is important if the sprayer is to do an accurate and uniform job of application.

G74-121 Sandbur Control In Field Corn (Revised January 1999), Gail A. Wicks, Robert G. Wilson Jr.

University of Nebraska-Lincoln Extension: Historical Materials

Sandbur can be a major weed problem in cornfields if not properly controlled. This NebGuide discusses mechanical and chemical alternatives for controlling sandbur.

Sandbur is a problem weed on coarse to fine-textured soil. The North Platte Valley, southwest and west central Nebraska, and the Sandhills are areas in the state where sandbur is a major weed problem in corn. Sandbur seldom becomes a primary weed problem in eastern Nebraska. Both field (Cenchrus pauciflorus Benth.) and longspine [Cenchrus longispinus (Hack.) Fern.] sandbur grow in Nebraska.
