As increased attention is focused on the issue of water quality in the state of Iowa, policymakers must grapple with the pressures of balancing federal water quality requirements, tight conservation budgets, and citizen concern for environmental preservation and restoration of Iowa’s water resources. Efforts to improve water quality typically entail significant costs, either in the form of state resources to fund cleanup efforts or private costs associated with altering land uses, farming practices, municipal treatment facility expansions, or other investments.

On October 12–13, a workshop funded by the National Science Foundation was held at Iowa State University in Ames, Iowa with a goal of identifying research needs related to coupled economic and biophysical models within the FEW system. Approximately 80 people attended the workshop with about half representing the social sciences (primarily economics) and the rest from the physical and natural sciences. The focus and attendees were chosen so that findings would be particularly relevant to SBE research needs while taking into account the critical connectivity needed between social sciences and other disciplines. We have identified several major gaps ...


The Optimality Of Using Marginal Land For Bioenergy Crops: Tradeoffs Between Food, Fuel, And Environmental Services, Adriana M. Valcu-Lisman, Catherine L. Kling, Philip W. Gassman 2017 Iowa State University

The Optimality Of Using Marginal Land For Bioenergy Crops: Tradeoffs Between Food, Fuel, And Environmental Services, Adriana M. Valcu-Lisman, Catherine L. Kling, Philip W. Gassman

Catherine Kling

We assess empirically how agricultural lands should be used to produce the highest valued outputs, which include food, energy, and environmental goods and services. We explore efficiency tradeoffs associated with allocating land between food and bioenergy and use a set of market prices and nonmarket environmental values to value the outputs produced by those crops. We also examine the degree to which using marginal land for energy crops is an approximately optimal rule. Our empirical results for an agricultural watershed in Iowa show that planting energy crops on marginal land is not likely to yield the highest valued output.

Nonpoint source pollution from agriculture is the main source of nitrogen and phosphorus in the stream systems of the Corn Belt region in the Midwestern US. The eastern part of this region is comprised of the Ohio-Tennessee River Basin (OTRB), which is considered a key contributing area for water pollution and the Northern Gulf of Mexico hypoxic zone. A point of crucial importance in this basin is therefore how intensive corn-based cropping systems for food and fuel production can be sustainable and coexist with a healthy water environment, not only under existing climate but also under climate change conditions in ...

Nurse Cropping In Potato Systems, John M. Jemison Jr. 2017 University of Maine Cooperative Extension

Nurse Cropping In Potato Systems, John M. Jemison Jr.

Cooperative Extension - Agriculture

In the summer of 2016, a study was conducted at the Rogers Farm in Stillwater, Maine to study the effect of short-term nurse crops on potato yield and quality. The study was designed as a randomized complete block design with six replications. The study compared two sowing rates (winter rye at 100 vs. 200 lbs/ac) to 20 lbs of annual ryegrass or a check plot (no nurse crop). In addition, each of the winter rye treatments was either killed with an herbicide prior to one-pass hilling or just hilled. To address the question of how long to grow a ...


Use Of Endomaxx Mycorrhizal Seed Treatment To Improve Potato Production In Maine, John M. Jemison Jr. 2017 University of Maine Cooperative Extension

Use Of Endomaxx Mycorrhizal Seed Treatment To Improve Potato Production In Maine, John M. Jemison Jr.

Cooperative Extension - Agriculture

With the increasing cost of fertilizer and the ever-decreasing supply of apatite worldwide, improving phosphorus (P) uptake should be a goal for all producers. Due to our high levels of iron and aluminum oxides in Maine soils, P efficiency is very poor. As a result, potato farmers tend to over apply P to ensure that their crop will have adequate P. Over time, this has led to increasing plant available soil test P levels. I recently requested the Maine Soil Test Lab director for potato soil tests over the past ten years. The percentage of soils testing above 40 lbs ...


Setting Up Living Trusts, Neil E. Harl 2017 Iowa State University

Setting Up Living Trusts, Neil E. Harl

Neil E. Harl

The recent enthusiasm for setting up revocable living trusts is supported by two pluses — (1) a way to assure flexibility in management for property in those later years when individuals may not be in a good position to manage their assets and (2) an opportunity for some simplification in estate settlement. However, several factors of a technical or practical nature should be taken into account before the decision is made to establish a revocable living trust.


Joint Tenancy Disclaimers: What Can Be Disclaimed?, Neil E. Harl 2017 Iowa State University

Joint Tenancy Disclaimers: What Can Be Disclaimed?, Neil E. Harl

Neil E. Harl

For years the Internal Revenue Service resisted the disclaimer of joint tenancy interests on the grounds that the disclaimer had to occur within nine months of the creation of the joint tenancy. IRS eventually came to accept the disclaimer of revocable joint tenancies within nine months after death and even more recently indicated that the Service would not resist the disclaimer of joint tenancy interests in other than revocable joint tenancies where there was a predeath right to sever the joint interests The focus on when joint tenancies could be disclaimed obscured the question of what could be disclaimed.

Capitalizing Preproductive Period Expenditures, Neil Harl 2017 Selected Works

Capitalizing Preproductive Period Expenditures, Neil Harl

Neil E. Harl

Few have forgotten the provision in the Tax Reform Act of 1986 requiring the capitalization of preproductive period expenditures for animals or crops having a preproductive period of more than two years. The provision was repealed as to animals in the Technical and Miscellaneous Revenue Act of 1988. However, problems may now be encountered by those who elected out of the provision before 1989.


Cash Accounting For Farm And Ranch Corporations, Neil E. Harl 2017 Iowa State University

Cash Accounting For Farm And Ranch Corporations, Neil E. Harl

Neil E. Harl

As a new taxpayer, a farm or ranch corporation may elect the cash or accrual methods of accounting if the corporate books are so kept and the method clearly reflects income. Indeed, IRS has ruled that a corporation may report on the cash method of accounting even though books are kept on the accrual method if the corporation maintains work papers reconciling accrual method book income to cash method taxable income. The method of accounting should be elected clearly on the initial corporate income tax return.


Funding Revocable Living Trusts, Neil E. Harl 2017 Iowa State University

Funding Revocable Living Trusts, Neil E. Harl

Neil E. Harl

Without much doubt, the transfer of assets to the trust is the most critical part of the formation of a revocable living trust. Inasmuch as all of the grantor's property should be conveyed to the trust, the obvious question is whether the transfer triggers adverse consequences to the grantor. In general, conveyance of property to a revocable inter vivos trust can be accomplished without negative consequences but the property inventory should be subjected to an itemby- item review before the actual transfer occurs. Here are the major points to consider.


Family Estate Trusts, Neil E. Harl 2017 Iowa State University

Family Estate Trusts, Neil E. Harl

Neil E. Harl

The recent attention to revocable living trusts has led to some confusion with a far less useful concept, the trust referred to variously as the "family estate" trust, "pure" trust, and "constitutional" trust. The latest version of these trusts, all of which are valued as substantially less than worthless, is the two-trust off-shore version or the foreign tax haven double trust. The trusts are mostly sold door-to-door through local contacts who tout the trusts as devices to solve all of one's estate-planning problems. The trusts are purportedly irrevocable, generally for a 25-year term.


Handling Commodity Futures Transactions, Neil E. Harl 2017 Iowa State University

Handling Commodity Futures Transactions, Neil E. Harl

Neil E. Harl

In the same manner as other merchants and manufacturers, farm and ranch taxpayers buy and sell commodity futures to hedge against fluctuating prices. Likewise, farm and ranch taxpayers buy and sell commodity futures as speculators. The principal matter of concern from an income tax perspective in the farm and ranch area is the line between hedging and speculation.


An 8-Zone Iso-Ne Test System With Physically-Based Wind Power, Wanning Li, Leigh Tesfatsion 2017 Iowa State University

An 8-Zone Iso-Ne Test System With Physically-Based Wind Power, Wanning Li, Leigh Tesfatsion

Economics Working Papers

This study extends the agent-based 8-Zone ISO-NE Test System to include wind turbine agents, each characterized by location, physical type, and an output curve mapping local wind speed into wind power output. Increases in wind power penetration (WPP) are modeled as build-outs of investment queues for planned wind turbine installations. The extended system is used to study the effects of increasing WPP under both stochastic and deterministic day-ahead market (DAM) formulations for security-constrained unit commitment (SCUC).

For each tested WPP, the expected cost saving resulting from a switch from deterministic to stochastic DAM SCUC is found to display a U-shaped ...
