Control Algorithm Development And Simulation For Comparing Evaporative Pads And Sprinklers For Grow-Finish Pigs, Brett C. Ramirez, Steven J. Hoff, Jay D. Harmon

Brett Ramirez

Seasonal variability attributed to heat stress (HS) has a large economic impact on the US swine industry by reducing daily gain and finishing market weights. Strategies to mitigate HS lack evidence showing effectiveness in different climates and have not been adequately controlled to provide a thermally optimum environment for pigs. Hence, the goal of this study was to describe the initial experimental design and instrumentation as well as develop innovative control algorithms for operating evaporative pads (EPs) and sprinklers. Located in northeast Iowa, a four room (~1,875 head per room) grow-finish facility featured side-by-side rooms separated by a hallway ...

Subsurface Mimo: A Beamforming Design In Internet Of Underground Things For Digital Agriculture Applications, Abdul Salam 2019 Purdue University

Subsurface Mimo: A Beamforming Design In Internet Of Underground Things For Digital Agriculture Applications, Abdul Salam

Faculty Publications

In underground (UG) multiple-input and multiple-output (MIMO), the transmit beamforming is used to focus energy in the desired direction. There are three different paths in the underground soil medium through which the waves propagates to reach at the receiver. When the UG receiver receives a desired data stream only from the desired path, then the UG MIMO channel becomes three path (lateral, direct, and reflected) interference channel. Accordingly, the capacity region of the UG MIMO three path interference channel and degrees of freedom (multiplexing gain of this MIMO channel requires careful modeling). Therefore, expressions are required for the degree of ...

Proof-Of-The-Concept Of Spent Mushrooms Compost Torrefaction - Preliminary Studies Of Process Kinetics And The Influence Of Temperature And Duration On Calorific Value Of The Biochar, Ewa Syguła, Jacek A. Koziel, Andrzej Białowiec

Agricultural and Biosystems Engineering Publications

Poland is the 3rd producer of mushrooms in the world. Mushroom production in Poland accounts for nearly 25% of the total production in the EU, and it is still growing. One type of waste generated during mushroom production is mushroom spent compost (MSC), with a 5:1 (MSC: mushrooms) production rate. We investigated valorizing the MSC to produce fuel via torrefaction (‘roasting’, a.k.a. low-temperature pyrolysis). Specifically, we developed models for the MSC torrefaction kinetics using thermogravimetric analyses (TGA) and the effects of torrefaction temperature (200~300 °C) and process duration time (20~60 min) on the resulting biochar ...

Techno-Economic Analysis (Tea) And Life Cycle Assessment (Lca) Of Maize Storage For Small And Middle Sized Farmers, Rashid Suleiman, Kurt A. Rosentrater

Agricultural and Biosystems Engineering Publications

Maize is the most widely cultivated cereal crop worldwide, currently ranked the third most important crop globally after wheat and rice. It is a key staple food in many developing countries. However, maize is produced on a seasonal basis, usually harvest once per year. To maintain a constant supply throughout the year, maize should be properly stored. But this may entail high cost and high-energy consumption, which can contribute significant amounts of greenhouse gas emissions. In this study, three storage capacities (25,000 bu, 250,000 bu and 2,500,000 bu) of maize were evaluated for economic analysis and ...


The Impact Of Different Data Processing Methods On Site-Specific Management Recommendation, Zhengzheng Gao 2019 University of Nebraska-Lincoln

The Impact Of Different Data Processing Methods On Site-Specific Management Recommendation, Zhengzheng Gao

Dissertations and Theses in Agricultural Economics

Understanding the impact of different data processing methods on site-specific management recommendation is vital to famers and consultants. This thesis investigates how data processing methods affect variable selection in production function estimation and the consequent economically optimal input use recommendation map. We utilized LASSO, a regression analysis method for feature selection. Data are collected from two years of on-farm trials from the same field in Hamilton county, Nebraska. Results suggest that the feature selection process and final recommendation about seed and nitrogen rates can be very sensitive to the way we process and analyze data, and the effects can be ...

Online Journal of Rural Research & Policy

To compensate the US producers affected by the “trade war” with China, the United States Department of Agriculture (USDA) offered direct payments to producers using 2018 production levels under the Market Facilitation Program (MFP). Results of the revenue efficiency analysis of the MFP payments show the average producers in 12 out of 14 major corn and soybean producing states were compensated such that their 2018 per acre revenue was more than their 2017 per acre revenue. Conversely, an average producer in those states that experienced drought was under-compensated, as their total per acre revenue after the MFP payment was less ...

Maize System Impacts Of Cover Crop Management Decisions: A Simulation Analysis Of Rye Biomass Response To Planting Populations In Iowa, U.S.A., Guillermo S. Marcillo, Sarah Carlson, Meghan Filbert, Tom C. Kaspar, Alejandro Plastina, Fernando E. Miguez

Alejandro Plastina

Cover crops provide environmental services that can effectively reduce the negative impacts from otherwise highly productive row-crop systems in the US Midwest. In this context, winter rye [(Secale cereale sp.)] is the most commonly used cover crop among producers because it overwinters and produces considerable biomass in the spring. While the soil and water benefits of a maize-rye system are well documented, the extent to which these benefits change under different rye planting densities has not been fully explored. In particular, shoot-biomass of a fall-seeded rye cover crop is expected to respond to increasing plant populations (PP), influence maize system ...


Is Arc-Co Acting As A Safety Net Program? Evidence From Iowa, Alejandro Plastina, Chad Hart 2019 Iowa State University

Is Arc-Co Acting As A Safety Net Program? Evidence From Iowa, Alejandro Plastina, Chad Hart

Alejandro Plastina

THE AGRICULTURAL Act of 2014, referred to as the 2014 Farm Bill, is the legislative backbone of federal farm income support programs and agricultural disaster assistance programs. These programs, combined with federal crop insurance, are what is typically referred to as the farm safety net. As the debate has begun for the next version of the Farm Bill, policy discussions have centered on improving the effectiveness of the safety net. However, in previous Farm Bills, there had been a concerted effort to utilize decoupled agricultural support to ensure that US farm programs would meet World Trade Organization (WTO) standards. The ...

The Effect Of Labeling Information Framing On Genetically Modified Food Choices: A Query Theory Account, Taylor Pruitt

Agricultural Economics and Agribusiness Undergraduate Honors Theses

The progression of policy that regulates genetically modified (GM) food in the US is a prime example of how the role of the government reformulates in relation to societal changes. Support for various labeling programs is formed around key themes which center on the benefits and costs associated with GM labels. The goal of this experiment was to explore the effect of information framing on GM food choices. This was accomplished by presenting information for or against GM labeling in terms of the benefits (positive framing) or costs (negative framing) to consumers. 1,410 consumers participated in an economic experiment ...

Comprehensive Poultry Supply Chain Model With Vertical And Horizontal Linkages: Implication Of Domestic And International Shocks, Hakan Unveren

Theses and Dissertations

According to USDA FAS, in 2017, the US was the largest broiler-producing country with 18.696 million metric tons and the second largest exporter of broiler products with 3.075 million metric tons (Brazil is the largest exporter with 3.847 million metric tons). Thus, around 83% of US production is consumed domestically. According to USITC, chickens are the most important protein source in the US, and Americans consume more chicken per capita than any other country. However, while the broiler industry is a key segment of US agriculture, it is underserved by large-scale supply-chain and trade models.
