G96-1362 Soil Temperatures And Spring Planting Dates, Steven J. Meyer, Allen L. Dutcher

University of Nebraska-Lincoln Extension: Historical Materials

Dates on which soil temperatures reach a threshold value are presented as a spring planting guide for agronomic and horticultural producers.

For a seed to germinate it must have good contact with the soil and be placed in a favorable soil environment. A good soil environment is one that has suitable soil temperature, adequate soil moisture, good aeration, and for certain seeds, light. Conditions necessary for germination depend on the species and variety of seed being planted. Alone, none of these factors guarantee germination; rather it is the interaction of these factors that affects seed germination.

In Nebraska, soil moisture …

Ec95-1873 Cultural Practices That Influence Wheat Diseases, John E. Watkins, Robert N. Klein, Paul C. Hay, Lenis Alton Nelson

University of Nebraska-Lincoln Extension: Historical Materials

The health of a wheatcrop is determined well before the crop is planted. It is often the result of subtle factors in the management history of the field, including varieties, seed quality, seedbed, planting date, residue management and post harvest weed control. Wheat health management practices before the crop is planted must limit, as much as possible, the number of production hazards that must be dealt with after planting. Important diseases influenced by cultural practices include crown and root rot, wheat streak mosaic, soil-borne wheat mosaic, barley yellow dwarf, leaf rust, smut diseases, scab, Cephalosporium stripe and tan spot.

Ec95-141 Nebraska's Manure Resource, D. H. Sander, J.E. Power, B. Eghball

University of Nebraska-Lincoln Extension: Historical Materials

Manure is a valuable resource that is sometimes perceived as a liability. For centuries, manure has provided needed nutrients which increased and stabilized food production. With the advent of inorganic chemical fertilizers, the value of manure as a nutrient source decreased because hauling and spreading costs were higher than the cost of chemical feritlizers. In addition, the water content of manure is high and even when the water is removed, its nutrient content is low compared to chemical fertilizers. Therefore, manure has often been viewed in American agriculture as a "waste" to be disposed of rather than a resource to …

G95-1132 Estimating Percent Residue Cover, David P. Shelton, Paul J. Jasa, John A. Smith, Roger Kanable

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide briefly describes the direct observation, line-transect, photo comparison, and calculation methods that are used to estimate the percentage of the soil surface covered with crop residue. Leaving crop residue on the soil surface is the easiest and most cost-effective way to reduce soil erosion caused by water and wind. Residue reduces water erosion by lessening the impact of the raindrops, thus reducing the amount of soil that is detached. It also slows flowing water, reducing the amount of soil that can be transported. Residue helps reduce wind erosion by reducing wind velocity near the soil surface and by …

G94-1198 Switchgrass And Big Bluestem For Grazing And Hay, Robert B. Mitchell, Lowell E. Moser, Bruce Anderson, Steven S. Waller

University of Nebraska-Lincoln Extension: Historical Materials

The grazing management and cultural practices discussed in this NebGuide can make switchgrass and big bluestem high quality summer forage. Switchgrass and big bluestem are native warm-season grasses that can provide abundant, high-quality forage during summer. Switchgrass and big bluestem produce 70 to 80 percent of their growth after June 1 in Nebraska, while more than 75 percent of cool-season grass growth, such as bromegrass and bluegrass, occurs before June 1. Therefore, switchgrass and big bluestem can provide forage to graze after cool-season pastures have been utilized. However, switchgrass and big bluestem must be managed differently than cool-season grasses. Poor …

Ec94-135 Understanding Pesticides And Water Quality In Nebraska, Steven D. Comfort, Patrick J. Shea, Fred W. Roeth

University of Nebraska-Lincoln Extension: Historical Materials

Groundwater is Nebraska's most important natural resource. The principal source of groundwater in Nebraska is the High Plains Aquifer System.

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.

• provides a varied habitat for many wildlife species;

• protects the soil from wind and water erosion;

• preserves a "germplasm bank" for many plant species that may become important for yet unknown uses;

• purifies and enhances the environment by cleasing the air, filtering the runoff to streams, increasing the intake of precipitation, and aiding …

G92-1076 Canola Production, Lenis Alton Nelson, Alan Grombacher

University of Nebraska-Lincoln Extension: Historical Materials

Canola, which produces a vegetable oil low in saturated fat, has potential for becoming an alternative crop for Nebraska agriculture. Canola produces an oil that has the lowest saturated fat content of any vegetable oil. Today, there is an increasing demand for this oil by diet-conscious consumers. In 1985, the U.S. Food and Drug Administration (FDA) recognized rapeseed and canola as two different species, based on their content and uses. Rapeseed oil is used in industry, while canola oil is used for human consumption. High erucic acid rapeseed (HEAR) oil contains 22-60 percent erucic acid, while low erucic acid rapeseed …

G92-1081 Factors That Affect Soil-Applied Herbicides, R. S. Moomaw, Robert N. Klein, Alex Martin, Fred Roeth, P.J. Shea, G.A. Wicks, R. G. Wilson

University of Nebraska-Lincoln Extension: Historical Materials

Characteristics of soil-applied herbicides are discussed, including site of uptake by weeds, solubility, adsorption, persistence, leaching potential, photodecomposition, and volatility. For best performance, preemergence and preplant herbicides must be placed in the top 0 to 3 inches of soil. Placement is important because the herbicide must enter the germinating weed seedling in order to kill it. Herbicides can be blended into the soil by mechanical incorporation, rainfall, or sprinkler irrigation, depending on the herbicide. Herbicide characteristics that determine their performance are site of uptake by weeds, solubility, adsorption, persistence, leaching potential, photodecomposition, and volatility. An understanding of these factors will …
