Ec89-723 Irrigation Scheduling Using Soil Moisture Blocks In Silty Soils, William L. Kranz, Dean E. Eisenhauer

University of Nebraska-Lincoln Extension: Historical Materials

Irrigation takes some risk out of crop production by providing a reliable source of water that allows the producer to manage soil water. Monitoring soil water is fundamental to determining how much irrigation water should be applied, and when the soil is able to store the amount of water to be applied.

This publication describes how to use soil mositure blocks to schedule irrigations in fine textured soils.

Ec89-724 Irrigation Scheduling Using Tensiometers In Sandy Soils, William L. Kranz, Thomas Dorn, Dean E. Eisenhauer

University of Nebraska-Lincoln Extension: Historical Materials

Monitoring soil moisture is fundamental to determining how much irrigation water should be applied and when the soil is able to store the amount of water to be applied. Establishing when and how much water should be applied is often referred to as irrigation scheduling.

This extension circular discusses soil moisture terms; what is a tensiometer, its installation and use; and worksheet.

G89-923 Windbreak Maintenance And Renovation, Jon Wilson, Mike Kuhns

University of Nebraska-Lincoln Extension: Historical Materials

What are you doing to maintain your windbreak? Is renovation necessary? This NebGuide can help you decide.

Windbreaks are integral parts of many Nebraska farming and ranching operations. They protect man, animals, crops and buildings from cold winter winds, hot summer winds, and deep snows. Windbreaks prevent wind erosion and provide wildlife habitat.

All windbreaks, even well-designed ones, need regular maintenance. Some windbreaks, especially those that are older or neglected, may need more drastic treatment or renovation.

G89-950 Horse Insect Control Guide, John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

Insects that bother horses, and ways to treat them, are covered here.

People keep horses in Nebraska for a number of different reasons. Some are for 4-H projects and urban users (recreational), ranch and farm (work), breeding farms, and racing.

Some of the insect pests of horses are also pests of other livestock species. Other insects are specific to horses, but may be pests only on farm and ranch horses.

The best methods of pest control vary depending upon the type of horse production.

G89-932 Minimum Center Pivot Design Capacities In Nebraska, William L. Kranz, Derrel L. Martin, Greg Lackas

University of Nebraska-Lincoln Extension: Historical Materials

Factors to consider in choosing an appropriate center pivot design are covered here. Irrigators investing in a center pivot irrigation system need to consider this important question: How much supplemental water is required by the crop? Irrigation system capacity needed to meet crop requirements is defined in units of gallons per minute (GPM) or gallons per minute per acre (GPM/AC). If the system capacity is too low, crop stress occurs during some portion of the growing season. If the capacity is too high, surface runoff may result, or capital investment for the pumping plant and center pivot may be greater …

G89-906 Barley Yellow Dwarf Disease Of Barley, Oats, And Wheat, John E. Watkins, Leslie C. Lane

University of Nebraska-Lincoln Extension: Historical Materials

The symptoms of barley yellow dwarf are covered here, as are disease occurrence and spread, and control.

Barley yellow dwarf (BYD) is distributed worldwide. It is the most economically important disease of barley and oats in North America. Barley yellow dwarf, wheat streak mosaic (WSM) and soil-borne wheat mosaic (SBWM), are three virus diseases that caused serious cereal grain yield losses in Nebraska during the last decade.

Since the mid-1980s barley yellow dwarf has become increasingly widespread in Nebraska, and now is a serious concern to oat and wheat producers. Outbreaks occasionally reach epidemic proportions as occurred in wheat in …
