More On Fobe, Neil Harl

Agricultural Law Digest

The family-owned business exclusion, enacted as part of the Taxpayer Relief Act of 1997 contained numerous omissions and ambiguities as enacted. A letter from the Joint Committee on Taxation to Sen. Charles E. Grassley of Iowa has provided additional insights into JCT’s view of how the statute should be interpreted.

Income Averaging, Neil Harl Dec 1997

Income Averaging, Neil Harl

Agricultural Law Digest

Although the possibility of a return to income averaging had been discussed for several years, enactment of income averaging for farm income came as a great surprise to many. The provision is not effective until 1998, and remains available for 1999 and the year 2000, and sunsets at the end of 2000 unless extended by legislative action.


Toward A Theory Of Food And Agriculture Policy Intervention For A Developing Economy With Particular Reference To Nigeria, Gbolagade B. Ayoola Dec 1997

Toward A Theory Of Food And Agriculture Policy Intervention For A Developing Economy With Particular Reference To Nigeria, Gbolagade B. Ayoola

CARD Working Papers

Following three months as a visiting scholar in the Department of Economics at lows State University, the author documents the results of his discussions regarding the policy process for agriculture and rural development in developing countries. His goal in this study is to initiate a process that will lead to a concise theory of policy intervention specifically suitable for the prevailing conditions in developing countries. He discusses the main features of the Nigerian agricultural polio environment to arouse interest in the analysis of that environment in relation to the advanced agricultural system of the United States.


Nafta And U.S.-Mexican Beef Trade: Long-Run Implications For Changes In Trade Flows From Technology Transfers, Bryan E. Melton, Wallace E. Huffman Dec 1997

Nafta And U.S.-Mexican Beef Trade: Long-Run Implications For Changes In Trade Flows From Technology Transfers, Bryan E. Melton, Wallace E. Huffman

Economic Staff Paper Series

This study examines potential long-term impacts on the U.S. and Mexican beef industries of the reduction in trade barriers under NAFTA and likely associated international technology transfers (of beef cattle, feeding methods, and meat packing) and foreign capital investments. The beef industry is represented as four subsectors: cow-calf production, post-weaning beef production, meat packing, and leather production. The analysis is accomplished through a multi-sector model of the U.S. and Mexican beef industries, estimation of key parameters, and simulation of long-run outcomes under three alternative scenarios. Our results show that Mexico will dramatically expand the size of its cow ...


Off-Farm Work Participation, Off-Farm Labor Supply And On-Farm Labor Demand Of U.S. Farm Operators, Wallace E. Huffman, Hisham El-Osta Dec 1997

Off-Farm Work Participation, Off-Farm Labor Supply And On-Farm Labor Demand Of U.S. Farm Operators, Wallace E. Huffman, Hisham El-Osta

Economic Staff Paper Series

An agricultural household model provides the framework for modeling off-farm work participation and off-farm and on-farm work decisions of farm operators. The empirical results are obtained from fitting the econometric model to data from a large national survey. In the estimated structural off-farm work participation equation, the operator's off-farm wage offer has a strong positive effect and other household income has a negative effect on the probability of off-farm work. For farm operators who participate in off-farm work, the wage elasticity of their off-farm labor supply is positive but of their on-farm labor demand is zero. The income elasticity ...


Agricultural Research: Benefits And Beneficiaries Of Alternative Funding Mechanism, Wallace E. Huffman, Richard E. Just Dec 1997

Agricultural Research: Benefits And Beneficiaries Of Alternative Funding Mechanism, Wallace E. Huffman, Richard E. Just

Economic Staff Paper Series

The United States has developed a very successful R&D system for agriculture. It is a system with shared cost/financing and performance by the federal and state governments and by the private sector. The paper presents an economic analysis of alternative organization, management, incentive, and funding mechanisms for agricultural research under budget constraints, including some emphasis on thekinds of benefits thatare generated and thegroups that receive them. We conclude that the private sector should bepermitted to carry outresearch that it finds profitable to undertake withminimal competition firom the public sector. The public research institutions should focus on general and ...


Informality, Size, And Regulation: Theory And An Application To Egypt, Marcelo M. Giugale, Sherif El-Diwany Dec 1997

Informality, Size, And Regulation: Theory And An Application To Egypt, Marcelo M. Giugale, Sherif El-Diwany

CARD Working Papers

The paper shows how, when the enforceability of regulations is size-sensitive, price competition can lock firms into informality and, thus, smallness, depending on the form of the production function. In that context, exogenous "help" packages targeted to informal firms "promote" micro and small enterprises (i.e., increase their numbers) but do not "develop" them (i.e., foster their growth). The "help" only generates a short-term span of abnormal profits for existing informal firms, and a long-term income transfer toward informal-market consumers. The model is tested in the context of Egypt's micro and small enterprise sector.

Agricultural Trade Liberalization And Capital Flows In The Americas, James Reitzes, Gordon C. Rausser, Roger Hickey, Jeremy Arnone Dec 1997

Agricultural Trade Liberalization And Capital Flows In The Americas, James Reitzes, Gordon C. Rausser, Roger Hickey, Jeremy Arnone

GATT Research Papers

In the second of three related papers, the authors develop a model that estimates the effects on prices, outputs, and trade flows arising from the elimination of U.S. import tariffs on contemplate agricultural commodities from Latin America. Eight agricultural commodities and six countries were selected for analysis. The authors also assess how the increased trade flows from Latin America to the United States are likely to create additional investment in the agricultural sector in Latin American countries.

Factors Influencing Wetland Use By Canada Geese, David E. Naugle, Jeffrey S. Gleason, Jonathan A. Jenks, Kenneth E. Higgins, Paul W. Mammenga, Sarah M. Nusser Dec 1997

Factors Influencing Wetland Use By Canada Geese, David E. Naugle, Jeffrey S. Gleason, Jonathan A. Jenks, Kenneth E. Higgins, Paul W. Mammenga, Sarah M. Nusser

Statistics Publications

Seasonal and semi-permanent wetlands in eastern South Dakota were surveyed in 1995 and 1996 to identify habitat characteristics influencing wetland use by Canada geese (Branta canadensis maxima). Position of a wetland within the landscape and its area were important landscape-scale features influencing wetland use by geese. Our delineation of potential Canada goose habitat using a wetland geographic information system indicated that distribution and area of semi-permanent wetlands likely limit Canada goose occurrence in regions outside the Prairie Coteau. Periodicity in hydrologic cycles within landscapes also may influence goose use of wetlands in eastern South Dakota.


Simulating Nitrogen Management Effects Of Subsurface Drainage Water Quality, A S. Azevedo, P. Singh, Ramesh S. Kanwar, Lajpat R. Ahuja Dec 1997

Simulating Nitrogen Management Effects Of Subsurface Drainage Water Quality, A S. Azevedo, P. Singh, Ramesh S. Kanwar, Lajpat R. Ahuja

Agricultural and Biosystems Engineering Publications

Increased level of NO3-N in the drinking water supplies is a major health concern these days. The long-term effects of actual nitrogen (N) fertilizer management practices are not well understood. The use of computer models allows the simulation of different N management practices on a long-term basis and their related effects on water quality. The RZWQM (Root Zone Water Quality Model, Version 3.0) was used to simulate the long-term (1978–1992) impacts of N management practices (single N applications at 50, 100, 150, and 200 kg per ha; and single and split N applications at 150 and ...


Cooperatives And Corporate Farming Laws, Neil Harl Nov 1997

Cooperatives And Corporate Farming Laws, Neil Harl

Agricultural Law Digest

In 1982, Nebraska voters approved Proposition 300, Nebraska’s anti-corporate farming law. The Nebraska provision has been criticized for its detailed, complex and not completely consistent approach to limiting corporations. The constitutional measure bars corporations or syndicates from acquiring real estate in the state except for family farm or ranch corporations; nonprofit corporations; Indian tribal corporations; and several other categories of corporate enterprises. The Nebraska Supreme Court has now ruled on whether a nonstock cooperative involved in hog production was exempt from the law as a “non-profit corporation.”

Effects Of Bt Transformation On Diseases Of Corn, Gary Munkvold, W. Mark Carlton, Richard Hellmich, Marlin Rice Nov 1997

Effects Of Bt Transformation On Diseases Of Corn, Gary Munkvold, W. Mark Carlton, Richard Hellmich, Marlin Rice

Proceedings of the Integrated Crop Management Conference

The availability of genetically engineered com hybrids that are resistant to insect pests is an exciting development for com producers and the entire com industry. These hybrids are likely to become very popular as they continue to demonstrate dependable insect protection and yield performance. But these hybrids have other advantages as well. Because of the relationship between com insects, particularly the European com borer, and certain diseases, Bt hybrids have shown reduced levels of these diseases in side-by-side comparisons.


Effects Of Swine Manure Management Options On Groundwater Quality, Thad Hardeman Nov 1997

Effects Of Swine Manure Management Options On Groundwater Quality, Thad Hardeman

Proceedings of the Integrated Crop Management Conference

In 1994, there were 31 hog farms across the United States owning at least 10,000 sows and in 1995, there were 44 (Freese, 1994). This increasing number of large hog farms is evidence of the growing swine industry. This growth, however, has independent farmers, neighbors, environmentalists, and legislators in a quandary as to how the industry will evolve. These growing pains are of both an economic and environmental nature. Many topics need to be addressed as the production expands. One of the primary concerns of the growing hog industry is the issue of swine (Sus spp.) manure production.


Controlling Corn Rootworms: Old Technology Versus New, Jon J. Tollefson Nov 1997

Controlling Corn Rootworms: Old Technology Versus New, Jon J. Tollefson

Proceedings of the Integrated Crop Management Conference

As is typical with corn rootworms, densities during 1997 varied dramatically throughout the Corn Belt and even within states. Iowa and some of the states east were abundantly blessed with corn rootworms. To the north and west of Iowa, the insect was less abundant, even hard to find at times. Within states where numbers were generally high, there were pockets of very high numbers spread among more typical densities. The result was that there were numerous reports of poor soil insecticide performance, usually clumped within areas. In Iowa I was in a "hot spot" east of Maquoketa where a number ...


Stress Related Soybean Diseases, X. B. Yang, Sourn Sanogo Nov 1997

Stress Related Soybean Diseases, X. B. Yang, Sourn Sanogo

Proceedings of the Integrated Crop Management Conference

Soybean plants are subject to a wide array of stresses that ultimately render the plants susceptible to pathogens. Stresses can be classified in four categories: physical, biological, chemical, and physiological. Physical stresses include extreme variation in factors such as temperature and moisture. Conditions such as cold and wet soils are unfavorable to soybean plant growth, but are conducive to many root diseases. Similarly, agricultural chemicals such as fertilizers and herbicides, when applied in excessive amounts, can lead to increase in root diseases in soybean. Infestations by other pests, such as soybean cyst nematode and insects, can stress soybean plants and ...


Reliability Of Manure Application Rates To Predict Availability Of Swine Manure-N In Cornfields, David J. Hansen, Alfred M. Blackmer Nov 1997

Reliability Of Manure Application Rates To Predict Availability Of Swine Manure-N In Cornfields, David J. Hansen, Alfred M. Blackmer

Proceedings of the Integrated Crop Management Conference

Efficient use of the nitrogen in animal manures is essential for economic and environmental reasons. It requires applying the manure appropriately and making adjustments for this N if commercial fertilizer also is applied. Estimates of the amounts of plant-available N supplied by animal manures commonly are based on amounts of manure-N applied. Adjustments are often made for expected losses of N soon after application. These estimates are made with the knowledge that there is unpredictable variability in amounts of N rendered unavailable by ammonia volatilization, surface runoff, inunobilization, leaching, or denitrification. Although it is known to be substantial, there has ...


Relative Emergence Of Weeds Of Corn And Soybean, Douglas D. Buhler, Robert G. Hartzler Nov 1997

Relative Emergence Of Weeds Of Corn And Soybean, Douglas D. Buhler, Robert G. Hartzler

Proceedings of the Integrated Crop Management Conference

The success of integrated weed management relies on matching control strategies to the specific weed problem in a field. This requires information not only on what weed species and how many of these weeds are present in a field, but also knowledge of the distribution of the weeds throughout the field and the stage of development of these weeds. Weed control recommendations typically provide information on appropriate tillage methods and herbicide selection. The information concerning weed infestations used to base these recommendations typically is not of sufficient detail to optimize the efficiency of these strategies. Information on weed populations can ...
