Veganic Agriculture In The United States: Opportunities For Research, Outreach, And Education, Alisha Utter, Mona Seymour

Journal of Extension

A growing number of farmers are excluding animal inputs from crop production, an approach commonly referred to as veganic or stockfree organic agriculture. This research-based article discusses the soil health and fertility strategies reported by a sample of U.S. veganic farmers. These approaches may be relevant beyond the veganic community to farmers seeking innovative methods for produce safety and nutrient cycling. Agricultural outreach professionals (AOPs), including Extension personnel, play a critical role in supporting veganic practices by serving as cross-pollinators between farmers and research institutions. Thus, the article endeavors to expand AOP familiarity with veganic practices and benefits.

Lrp-Feeder Cattle Insurance Usage Up With Recent Changes, Jay Parsons

Cornhusker Economics

Market uncertainties pose a significant risk to cattle producers, who have a substantial amount of money invested in breeding livestock, land, and other infrastructure. Live-stock Risk Protection (LRP) insurance became available in the early 2000s from the USDA Risk Management Agency to provide cattle and swine producers with a simple price risk management tool to protect against unexpected down-swings in the national market price. LRP is a single-peril insurance product that provides an indemnity to insured producers if a national price index falls below a selected coverage price on the end date of the policy. LRP insurance functions like a …


Commitment Behaviour In The World Trade Organization's Trade Facilitation Agreement, Russell Hillberry Jul 2021

Commitment Behaviour In The World Trade Organization's Trade Facilitation Agreement, Russell Hillberry

Department of Agricultural Economics Faculty Publications

We use a new database of commitments made during the process of ratifying the Trade Facilitation Agreement (TFA) to study variation in countries’ commitment behaviour. The TFA is a novel World Trade Organization agreement because it allows developing countries to select commitments from a menu of best practices in trade facilitation, rather than to consent, or not, to a comprehensive package of negotiated commitments. The operation of this á la carte approach to concluding trade agreements is worthy of study in its own right, but the commitment data also offer a high-level description of progress in an international effort to …

Farm Life In The Asset Economy: First-Generation Farmers And The Agrarian Question, Elizabeth Pickard Jul 2021

Farm Life In The Asset Economy: First-Generation Farmers And The Agrarian Question, Elizabeth Pickard

Theses - ALL

A massive transition of land ownership is currently underway in the U.S. as an increasing proportion of farmers near retirement age with no successor in place. The question of who will replace them has come to the fore as policy makers and food justice activists alike contemplate a shift to a more equitable and ecologically sustainable food system. Embracing a "beginning farmer theory of change," some scholars have called for an increase in the number of first-generation farmers to account for the labor- and knowledge-intensive methods required for agroecological production. Others have brought attention to the historical and ongoing racial, …

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Diversifying agronomic production systems by combining crops and livestock (i.e., Integrated Crop Livestock systems; ICL) may help mitigate the environmental impacts of intensive single-commodity production. In addition, harvesting row-crop residues and/or perennial biomass could increase the multi-functionality of ICL systems as a potential source for second-generation bioenergy feedstock. Here, we evaluated non-CO2 soil greenhouse gas (GHG) emissions from both row-crop and perennial grass phases of a field-scale model ICL system established on marginally productive, poorly drained cropland in the western US Corn Belt. Soil emissions of nitrous oxide (N2O) and methane (CH4 ) were measured during the 2017–2019 growing seasons …

WhiB7 represents a distinct subclass of transcription factors in the WhiB-Like (Wbl) family, a unique group of iron-sulfur (4Fe-4S] cluster-containing proteins exclusive to the phylum of Actinobacteria. In Mycobacterium tuberculosis (Mtb), WhiB7 interacts with domain 4 of the primary sigma factor (σA4) in the RNA polymerase holoenzyme and activates genes involved in multiple drug resistance and redox homeostasis. Here, we report crystal structures of the WhiB7:σA4 complex alone and bound to its target promoter DNA at 1.55-Å and 2.6-Å resolution, respectively. These structures show how WhiB7 regulates gene expression by interacting with both …


Joint Bidding In Conservation Auctions: An Experimental Study Of Policy Design And Performance, Simanti Banerjee Jul 2021

Joint Bidding In Conservation Auctions: An Experimental Study Of Policy Design And Performance, Simanti Banerjee

Cornhusker Economics

In designing conservation policies both ecologists and economists have argued that greater spatial coordination of producer land use adoption can improve environmental outcomes for a range of important environmental targets such as wetlands restoration, nutrient pollution reduction,and species conservation. Economists have suggested two types of incentive policies for achieving such spatial coordination: the Agglomeration Bonus (AB) (Parkhurst and Shogren, 2007) and spatially-connected auctions (Banerjee et al., 2015). However, a majority of the analyses to date have focused on incentives aimed at individual land manager participation in such schemes (e.g., Fooks et al., 2016). In contrast, a number of countries such …

Autonomous equipment for crop production is on the verge of technical and economic feasibility, but government regulation may slow its adoption. Key regulatory issues include requirements for on-site human supervision, liability for autonomous machine error, and intellectual property in robotic learning. As an example of the impact of regulation on the economic benefits of autonomous crop equipment, analysis from the United Kingdom suggests that requiring 100% on-site human supervision almost wipes out the economic benefits of autonomous crop equipment for small and medium farms and increases the economies-of-scale advantage of larger farms.
