Increasing commercial fertilizer costs and regulatory mandates will encourage application of manure as a nutrient source in the future.


Ec95-815 Extending The Safe Drinking Water Act: Issues And Alternatives, Roy Frederick Jan 1995

Ec95-815 Extending The Safe Drinking Water Act: Issues And Alternatives, Roy Frederick

University of Nebraska-Lincoln Extension: Historical Materials

Author's note: This publication was written in the months immediately prior to the beginning of the 104th Congress in January, 1995. While the basic issues have not changed, the schedule for reauthorization of the Safe Drinking Water Act and the approach to issues may have been altered by the change in political-party leadership in the Congress. For example, contamination standards for drinking water may become a part of general "risk-assessment" legislation in 1995.

In 1974, Congress passed the Safe Drinking Water Act (SDWA), P.L. 93-523. Its purpose was to protect the nation's drinking water from harmful biological and chemical contaminants. …

University of Nebraska-Lincoln Extension: Historical Materials

Farmers' preferences are important in the development of farm bills. In that spirit, the Department of Agricultural Economics at the University of Nebraska-Lincoln and the Nebraska Agricultural Statistics Service recently asked a random sample of agricultural producers about their preferences for the 1995 farm bill. Similar surveys were undertaken in 1984 and 1989, prior to the last two farm bills. Each Nebraska survey was part of a larger, national effort. This year, 15 states, scattered across all regions of the United States, participated.

The purpose of this report is to summarize Nebraska producers' views on key issues likely to be …

Ec95-141 Nebraska's Manure Resource, D. H. Sander, J.E. Power, B. Eghball Jan 1995

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 …

G95-1135 Estimating Percent Residue Cover Using The Calculation Method, David P. Shelton, John A. Smith, Paul J. Jasa, Roger Kanable Jan 1995

G95-1135 Estimating Percent Residue Cover Using The Calculation Method, David P. Shelton, John A. Smith, Paul J. Jasa, Roger Kanable

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes how to use the calculation method to estimate the percent of the soil surface that will be covered with crop residue after using residue-disturbing implements and operations. Leaving crop residue on the soil surface is the easiest and most cost-effective method of reducing soil erosion. Research in Nebraska and other midwestern states found that leaving as little as 20 percent of the soil surface covered with crop residue can reduce soil erosion caused by rainfall and flowing water by one-half compared to residue-free conditions. Greater amounts of residue cover will further reduce erosion.

Survey Of Hematozoa And Intestinal Helminths Infecting Green-Winged Teal In Guthrie County, Iowa, Rick Klann, Bryan Hellyer

Journal of the Iowa Academy of Science: JIAS

Five helminths and one sporozoan were recovered from 21 hunter-killed green-winged teal collected from Lakin Slough in Guthrie County, Iowa during October and November of 1991. The sporozoan, Leucocytozoon simondi, was identified in blood smears from all 21 teal. The helminths recovered from the alimentary tract included three trematodes, Cotylurus flabelliformis, Echinostoma trivolvis and Zygocotyle lunata; a hymenolepid tapeworm; and one acanthocephalan, Corynosoma constrictum. The ecological factors associated with infection by these parasites are discussed.


Inheritance And Number Of Genes Affecting Quantitative Traits Within F2 Maize Populations, D. H. Schmidt, A. R. Hallauer Jan 1995

Inheritance And Number Of Genes Affecting Quantitative Traits Within F2 Maize Populations, D. H. Schmidt, A. R. Hallauer

Journal of the Iowa Academy of Science: JIAS

Populations derived from crosses of elite genotypes are commonly used in plant breeding programs. Knowledge of the genetic variation among individuals and their progenies within F2 populations is essential for effective selection of important traits. The genetic variation and number of effective factors affecting the expression of quantitative traits within 30 F2 maize (Zea mays L.) populations were determined by different methods suggested for study of F2 populations. Estimates of heritability and number of effective factors varied among F2 populations for each trait, primarily because of the differences in trait expression between parents of crosses and the environmental effects upon …
