G77-328 Irrigation Water Quality Criteria, Gary W. Hergert, Delno Knudsen

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide is intended to provide guidelines to help understand and interpret chemical water quality test results.

All well and stream waters contain dissolved minerals. The amounts and kinds of minerals vary from one location to another and may vary with time. When irrigation water is applied, the mineral salts are left in the soil after the crop has used the water. Most of these mineral salts are beneficial to crop growth and soil condition, but in some cases they may be harmful. Irrigation water quality problems may be caused by (1) total mineral salts accumulating so that crops no …

G77-386 Wheat In Poultry Rations, T.W. Sullivan, E.W. Gleaves

University of Nebraska-Lincoln Extension: Historical Materials

This publication examines the advantages and disadvantages of wheat as a component of poultry feed.

Wheat is usually considered a source of human food rather than an ingredient for poultry and livestock feeds. This is especially true in the United States, where corn, milo and other feed grains are abundantly produced. In recent years one of every two bushels of wheat produced in the United States has been exported. If world production and supplies of wheat are high, a surplus develops and wheat prices are lowered. When this situation occurs wheat becomes an attractive alternative to corn or milo in …

G77-374 Seasonal Prices For Meat Animals, Allen C. Wellman Jan 1977

G77-374 Seasonal Prices For Meat Animals, Allen C. Wellman

University of Nebraska-Lincoln Extension: Historical Materials

Seasonal variations in livestock prices seem to follow a similar pattern from year to year. For some classes of livestock, these seasonal swings in prices have been quite consistent for a number of years; while others have changed considerably over time.

Seasonal price fluctuations result mostly from seasonal supply changes or variations in marketings. For any given year a cyclical change in price may override the season pattern. Seasonal price changes during the 1972-76 period also were influenced by a price freeze, as well as changes in supply and demand.

Seasonal price changes are important factors to consider in planning …

G77-358 Artesian (Confinsed) Aquifers And Effect Of Pumping, Darryll T. Pederson, Deon D. Axthelm

University of Nebraska-Lincoln Extension: Historical Materials

Nebraskans are concerned about declining water levels in some domestic and stock wells.

Nebraskans are concerned about declining water levels in some domestic and stock wells. Drought and irrigation well development have been major factors. Water level declines have been especially pronounced during the pumping season in places where the aquifer is artesian or confined (a confined aquifer is also referred to as an artesian aquifer). Many domestic and livestock pumps may have to be set deeper in order to yield water. In nearly all cases water levels recover rapidly when the pumping season ends. Large water-level fluctuations are normal …
