• Nitrogen in our Environment
• Alternatives When Excessive Nitrate is Present in Drinking Water
• Nitrates, Nutrites and Methemoglobinemia
• Nitrates, Nutrities, N-Nitroso Compounds and Nutrition
• Excessive Nitrate/Nitrite Exposure: Nitrate Poisoning and Related Animal Health Effects
• Nitrates and Ground Water Quality Protection Policies

Ncr90-379 Sheep Diseases, R.M. Jordan

University of Nebraska-Lincoln Extension: Historical Materials

Sheep do get sick, but fewer would die if producers recognized that a problem existed, made the correct diagnosis, and treated sheep in the most effective manner. Correct diagnosis is most difficult. It requires experience, and the only way to get that experience is to make the effort. Consulting with your veterinarian can be most helpful.

The following brief comments are intended to provide some help in diagnosing, treating, and preventing some of the more prevalent health problems of sheep.

Ec90-431 Juggling Time, Work And Family, Cheryl A. Burkhart-Kriesel, Sandy Hatter, Kathleen Prochaska-Cue

University of Nebraska-Lincoln Extension: Historical Materials

Everyone agrees that time is a valuable resource. Each of us has a limited amount of it to use for work, family and leisure activities. As more demands are placed on us, our decisions on how we use our time become more difficult. Making the most of it becomes a necessity.

This extension circular discusses how to set your objectives and priorities, streamline decision-making processes, recognize scheduling hints and tools and effectively handle interruptions. Juggling the time demands of work and family, while working at a business in the home, requires additional considerations.

G90-945 A Gardener's Guide For Soil And Nutrient Management In Growing Vegetables, E.J. Penas, Dale T. Lindgren

University of Nebraska-Lincoln Extension: Historical Materials

How to manage soil and nutrients when growing vegetables is discussed here, as is soil testing, soil pH, organic matter, and the use of commercial fertilizers.

Using fertilizers as nutrient sources in growing vegetables is one cultural practice that can improve production if done correctly. This means using the right fertilizer material, applying it at the correct rate and time, and using the proper method of application.

Fertilizer needs for vegetables depend on the kind of vegetable grown, chemical properties of the soil, previous cropping history, and adequate water for plant growth. Guidelines here are based on soil chemical properties …

G90-974 The Beaf Leaf Beetle In Soybeans (Revised September 1994), Thomas E. Hunt, J. F. Witkowski, Robert J. Wright, Keith J. Jarvi

University of Nebraska-Lincoln Extension: Historical Materials

The identification and life cycle of the bean leaf beetle are discussed along with scouting techniques, economic thresholds, and cultural control tactics.

The bean leaf beetle is a common insect found in Nebraska soybean fields. The insect also feeds on peas, snap beans, and dry beans. Although present in alfalfa and sweet clover in the early spring before soybean emerges, the insect is not known to damage either legume.

Use integrated pest management (IPM) when planning how to reduce bean leaf beetle damage. Integrated pest management is a sustainable approach to managing pests by combining biological, cultural, physical, and chemical …

G90-1001 Spray Drift Of Pesticides, Larry D. Schulze, Robert Grisso, Robert Stougaard

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses conditions that cause particle drift, and methods private and commercial applicators may employ to reduce drift potential from pesticide spray applications.

Spray drift of pesticides away from the target is an important and costly problem facing both commercial and private applicators. Drift causes many problems including:

1. damage to susceptible off target sites,

2. a lower rate than intended which can reduce the effectiveness of the pesticide, wasting pesticide and money, and

3. environmental contamination, such as water pollution and illegal pesticide residues.

Drift occurs by two methods; vapor drift and particle drift. This NebGuide focuses mainly …

G90-980 Rose Mosaic And Rose Rosette Diseases, John E. Watkins

University of Nebraska-Lincoln Extension: Historical Materials

The rose mosaic and rose rosette diseases may cause a variety of symptoms, including reduced plant vigor and flower quality. Early detection is essential to control.

Roses have been cultivated as an ornamental for 4,000 to 5,000 years and now are distributed worldwide. Rose virus and virus-like diseases occur wherever roses are grown. Since roses are vegetatively-propagated through budding or grafting, these pathogenic agents are easily spread during propagation. Infection by virus or virus-like agents may cause a wide variety of symptoms. These can range from latent, symptomless infections to mosaic leaf patterns and distortions, severely distorted canes, and finally, …
