Quantifying The Combined Effect Of Abiotic Factors On The Decomposition Of Organic Matter In Semiarid Grassland Soils, Elnazsadat Hosseiniaghdam 2021 University of Nebraska-Lincoln

Quantifying The Combined Effect Of Abiotic Factors On The Decomposition Of Organic Matter In Semiarid Grassland Soils, Elnazsadat Hosseiniaghdam

Theses, Dissertations, and Student Research in Agronomy and Horticulture

Grassland ecosystems play a critical role in the global carbon cycle, and their cumulative carbon dioxide (CO2) emissions can be affected by animal grazing where litter (i.e., dead plant material) is trampled into the soil. However, the subsequent effects of trampling on litter decomposition are not well understood. Meanwhile, abiotic factors, especially temperature and soil moisture, are known to strongly affect litter decomposition. Due to the very small number of published studies that have considered litter placement, either litter on top of soil or litter mixed with soil as a factor in litter decomposition under different temperature and soil ...

Digital Urban Agriculture As Disparate Development: The Future Of Food In Three U.S. Cities Through The Lens Of Stakeholder Perceptions, Networks, And Resource Flows, Michael Carolan 2021 William & Mary Law School

Digital Urban Agriculture As Disparate Development: The Future Of Food In Three U.S. Cities Through The Lens Of Stakeholder Perceptions, Networks, And Resource Flows, Michael Carolan

William & Mary Environmental Law and Policy Review

Urban agriculture takes many forms. Often, the term elicits images of raised beds, hoop houses, and, in those instances where topsoil is both present and non-contaminated, in-ground gardens—what I call traditional urban agriculture (“TUA”). But that imagery is changing, especially in some parts of the country where vacant space is scarce and land prices dear. In those instances, cities are seeing growth in digital urban agriculture (“DUA”). DUA, as defined here, refers to farming within urban and peri-urban areas that incorporates elements of automation, software, and/or silicon-based hardware into their operations. While this definition is not meant to ...

Solanum Jamesii As A Food Crop: History And Current Status Of A Unique Potato, David Kinder, John Bamberg, Lisbeth Louderback, Bruce Pavlik, Alfonso Del Rio

Pharmacy Faculty Scholarship

Solanum jamesii is a wild potato found in the US southwest. There is ample evidence that this potato was used by ancestral Puebloans as a food source, where some researchers think it was used as a starvation food while others consider it to be regular food source. Currently this potato is being grown by Native Americans, notably the Navajo, as a specialty food as well as a food crop. There are several attributes to this potato that make it especially suitable for development as our climate changes and food needs become more demanding, including its drought tolerance and ability to ...

Crop Insurance Premium Subsidies Are A Means Of Income Redistribution, Charalampos Mavroutsikos, Konstantinos Giannakas, Cory Walters 2021 University of Nebraska-Lincoln

Crop Insurance Premium Subsidies Are A Means Of Income Redistribution, Charalampos Mavroutsikos, Konstantinos Giannakas, Cory Walters

Cornhusker Economics

The U.S. federal crop insurance is a major farm policy aimed at providing risk protection/reduced risk expo-sure to agricultural producers. A key component of this policy is the provision of multiple contract options and premium subsidies that reduce the cost of crop insurance to agricultural producers. Premium subsidies have been growing over time and accounted for more than $6 billion in government outlays in 2019, with $2 billion being applied to coverage levels of 80% and higher (USDA-RMA, 2020). While the government has justified the use of premium subsidies as a necessary means of increasing producer participation in ...

The Effect Of Anionic Surfactants On Herbicide Mixtures And Solutions, Ely Anderson 2021 University of Nebraska-Lincoln

The Effect Of Anionic Surfactants On Herbicide Mixtures And Solutions, Ely Anderson

Theses, Dissertations, and Student Research in Agronomy and Horticulture

Herbicide mixtures are popular for farmers to delay the evolution of herbicide-resistant biotypes from occurring and control existing herbicide-resistant weeds. Glufosinate is a contact herbicide that has been observed as a mixture partner with many herbicides. In many cases, antagonistic interactions have occurred when using glufosinate in mixture with other herbicides. The antagonistic interactions have resulted in applications with incomplete weed control. Adjuvants have been known to impact an herbicide application by increasing herbicide penetration, spreadability, and efficacy. Adjuvants added to glufosinate mixtures can impact spray applications and increase weed control. The objectives of this research were: (1) investigate the ...

The Wild Side Of Commodity Markets: Hedging In Times Of High Volatility, Fabio Mattos 2021 University of Nebraska-Lincoln

The Wild Side Of Commodity Markets: Hedging In Times Of High Volatility, Fabio Mattos

Cornhusker Economics

Commodity markets go through periods with low volatility when we generally see small variations in prices, as well as periods with high volatility, when we tend to see large swings in prices. Regardless of the degree of price volatility in the market, producers can always use marketing contracts as a way to hedge the price risk of their operation. Even though the general mechanics of hedging are the same in periods of low volatility and high volatility, some aspects of hedging become more evident in times of high volatility. In this article, we will discuss some of these aspects focusing ...
