Grocery Food Taxes And U.S. County Obesity And Diabetes Rates, Lingxiao Wang, Yuqing Zheng, Steven Buck, Diansheng Dong, Harry M. Kaiser
Agricultural Economics Faculty Publications
BACKGROUND: Grocery food taxes represent a stable tax revenue stream for state and municipal government during times of adverse economic shocks such as that observed under the coronavirus disease 2019 (COVID-19) pandemic. Previous research, however, suggests a possible mechanism through which grocery taxes may adversely affect health. Our objectives are to document the spatial and temporal variation in grocery taxes and to empirically examine the statistical relationship between county-level grocery taxes and obesity and diabetes.
METHODS: We collect and assemble a novel national dataset of annual county and state-level grocery taxes from 2009 through 2016. We link this data to ...
2020 Summary Of Herbicide Evaluations For Marestail (Horseweed) Control In Soybean, 2021 Iowa State University
2020 Summary Of Herbicide Evaluations For Marestail (Horseweed) Control In Soybean, Prashant Jha
Integrated Crop Management News
Marestail is one of the most widespread and troublesome weeds in Iowa croplands. It can grow to a height of 1.5 to 6 feet, produce up to 200,000 seeds, and can reduce soybean yields up to 80% if not controlled (Figure 1). Marestail seeds are light and disperse across landscapes with winds. Seeds have little dormancy and can germinate soon after seed shed. In general, 75% of seedlings germinate in fall, remain in rosette-stage until spring, begin stem elongation in April, and start flowering in July. About 25% of seeds germinate in the spring. Due to these unique ...

An Milp Model For Corn Planting And Harvest Scheduling Considering Storage Capacity And Growing Degree Units, Zahra Khalilzadeh, Lizhi Wang
Industrial and Manufacturing Systems Engineering Publications
Corn planting and harvest scheduling is an important problem due to having a significant impact on corn yield, balancing the capacities for harvest, transport, and storage operations. Different corn hybrids also have different planting window and poor planting and harvest schedules may cause erratic weekly harvest quantities and logistical and productivity issues. In the 2021 Syngenta Crop Challenge, Syngenta released several large datasets that recorded the historical daily growing degree units (GDU) of two sites and provided planting window, required GDUs, and harvest quantity of corn hybrids planted in these two sites. Then, participants of this challenge were asked to ...

Sectional Model Of A Prairie Buffer Strip In A Laboratory Flume For Water Quality Research, Andrew J. Craig, Michelle L. Soupir, Chris R. Rehmann
Agricultural and Biosystems Engineering Publications
Vegetative buffers have shown promising results in reducing runoff volume, sediment, nutrients, and manure‐borne contaminants in runoff from agricultural fields. Although these vegetative buffer systems have been extensively tested in field and plot‐scale studies that utilize either natural or simulated rainfall, studies of such systems under highly controlled conditions in the laboratory have been limited. Here, we present the development of a new system for laboratory testing of a full‐scale, sectional, physical model of a new practice under the Continuous Conservation Reserve Program (CRP) Clean Lakes, Estuaries, and Rivers (CLEAR) Initiative, CP‐43 Prairie Strips. This work ...

Developing Farmer Typologies To Inform Conservation Outreach In Agricultural Landscapes, 2021 Iowa State University
Developing Farmer Typologies To Inform Conservation Outreach In Agricultural Landscapes, Suraj Upadhaya, J. Gordon Arbuckle, Lisa A. Schulte
Understanding factors that motivate conservation behavior among farmers is crucial to addressing societal, soil, water, and wildlife conservation goals. Farmers employ soil conservation practices to maintain agricultural productivity while minimizing impacts to water and wildlife in the long-term. The majority of conservation programs are voluntary in nature and some farmers are more willing and/or able to implement conservation practices than others. To inform the development of more effective conservation outreach and incentive programs, we created a farmer typology using data from three waves (2015, 2016, 2018) of a longitudinal survey of 358 farmers from Iowa, a highly productive agricultural ...

Agricultural Innovation And Adaptation To Climate Change: Insights From Genetically Engineered Maize, Seungki Lee, Yongjie Ji, Giancarlo Moschini
CARD Working Papers
Climate change is one of the major threats to the global food supply, and adaptation by technological progress is believed to be essential. What is the scope of the required innovation tasks? To address this question, we estimate the yield gain in US maize production due to a major novel technology: genetically engineered (GE) varieties. Next, the yield model is used to extrapolate future expected yields given climate change projections from twenty large-scale models and two warming scenarios. We find that climate change entails significant yield shortfalls. The scale of these yield gaps, by the end of the century, ranges ...
