Alternatives For Implementation Of Integrated Crop Management (Icm) Programs In Local Agricultural Input Firms, Roger G. Ginder Jan 1995

Alternatives For Implementation Of Integrated Crop Management (Icm) Programs In Local Agricultural Input Firms, Roger G. Ginder

Leopold Center Completed Grant Reports

Levels of fertilizer and pesticide usage in Iowa may change in response to at least two forces. One is growing public concern about the envi­ ronment, which has resulted in increased regu­ lation of the manufacture, distribution, and application of chemical pesticide products. Use of some products has been severely re­ stricted, while others are under evaluation.


Gis-Based Environmental And Economic Analysis Of Integrated Crop-Livestock Production Systems In Southern Iowa, U. Sunday Tim, Robert W. Jolly, Daniel Otto Jan 1995

Gis-Based Environmental And Economic Analysis Of Integrated Crop-Livestock Production Systems In Southern Iowa, U. Sunday Tim, Robert W. Jolly, Daniel Otto

Leopold Center Completed Grant Reports

Crop and livestock production are important economic components for many rural com­ munities. In 1992, Iowa led the nation in corn and hog production, and ranked second, third, seventh, and eighth, respectively in soybean, cattle and calves, poultry, and dairy cow pro­ duction. Livestock and livestock products generated over 64% of the state's total cash farm receipts during 1992—more than $6.5 billion sales at the farm level.


An Economic Investigation Into Railroad Pricing And Car Allocation Programs , Gregory Roy Pautsch Jan 1995

An Economic Investigation Into Railroad Pricing And Car Allocation Programs , Gregory Roy Pautsch

Retrospective Theses and Dissertations

The movement of grain by the railroad industry is plagued by the consistent presence of car shortages and surpluses. Due to these difficulties and others the Staggers Rail Act of 1980 was passed;In the pre-Staggers system, the railroad chooses its tariff and capacity before knowing demand which creates the persistent cycle of car shortages and car surpluses. Shippers order conventional rail service, with full information, on a spot basis;Recently, railroads have instituted car ordering systems offering guaranteed service as well as conventional tariff service. Guaranteed service is ordered by shippers in advance and before possessing full grain market ...


Self-Insurance And Self-Protection In Weed Control: Implications For Nonpoint Source Pollution, David Walter Archer Jan 1995

Self-Insurance And Self-Protection In Weed Control: Implications For Nonpoint Source Pollution, David Walter Archer

Retrospective Theses and Dissertations

This dissertation investigates producer's weed control decisions in three papers. Using an endogenous risk framework, the papers model weed control decisions as they are affected by uncertainty and as they are affected by policies aimed at reducing nonpoint source pollution;The first paper adapts the theory of self protection and self insurance to weed control decisions in order to model substitutions between fertilizer and herbicides. Our results suggest that an increase in the probability of weed damage will generally decrease both herbicide and fertilizer application rates. We also show that increased probability of weed damage leads to use of ...

Health Uncertainty And Food Consumption In Low-Income Households In Lima, Peru , Chris Daniel Gingrich Jan 1995

Health Uncertainty And Food Consumption In Low-Income Households In Lima, Peru , Chris Daniel Gingrich

Retrospective Theses and Dissertations

This study investigates the relationships between health uncertainty and food consumption among low-income households in developing countries. The particular sample households are from Lima, Peru's bottom expenditure quartile. Several food and nonfood inputs are important factors affecting health status and health variance. In addition, there is strong evidence that expected health status and health risk affect the consumption of several food commodities;The model also provides a means of analyzing the effects of policy alternatives on food consumption, expected health status, and health risk. The results show that education programs and price subsidies for tubers and dairy products are ...


G95-1262 Feeding The Beef Cow Herd--Part Ii Managing The Feeding Program, Richard J. Rasby, Ivan G. Rush, Don C. Adams Jan 1995

G95-1262 Feeding The Beef Cow Herd--Part Ii Managing The Feeding Program, Richard J. Rasby, Ivan G. Rush, Don C. Adams

Historical Materials from University of Nebraska-Lincoln Extension

Feed costs are the cow/calf producer's greatest expense in producing a weaned calf. To remain competitive, cow/calf operators must use economical feeding programs. It is important to match the available feed resources with the nutrient requirements of the first-calf-heifer and cow. Both over- and underfeeding the cow herd can lead to high production costs.

Nutrient requirements for heifers calving as 2-year-olds and cows calving as 3-year-olds and older are shown in Table I. Beef cows are seldom fed complete rations where ingredients are weighed daily. Generally, most of a cow's ration is forages such as: 1 ...

A Spatial Decision Support System For Livestock Production Planning And Environmental Management, Dharmesh K. Jain, U. Sunday Tim, Robert W. Jolly Jan 1995

A Spatial Decision Support System For Livestock Production Planning And Environmental Management, Dharmesh K. Jain, U. Sunday Tim, Robert W. Jolly

Agricultural and Biosystems Engineering Publications

Spatial decision support systems are used to plan production systems and direct the implementation management strategies that are compatible with environmental protection goals. They enable resource managers to select appropriate production technologies that minimize environmental damage, and evaluate alternative management practices. This article describes a spatial decision support system (SDSS) developed to facilitate planning and management of environmentally sound livestock production. The SDSS integrates a geographic information system, spatial and biophysical modeling, and a knowledge-based system into an interactive tool to select suitable watershed land areas for siting livestock production, to select fields for manure application, and to determine the ...
