Optimization Of In-Vessel Food Waste Composting: Enzyme Activity And Microbial Dynamics, Ayawovi Selom Ametepe
Optimization Of In-Vessel Food Waste Composting: Enzyme Activity And Microbial Dynamics, Ayawovi Selom Ametepe
Graduate Theses and Dissertations
A series of greenhouse-based, rotary-drum bioreactor experiments was designed to study microbial dynamics and enzyme activity during optimization of food waste composting. This work aims to optimize food waste composting by defining the best food waste-to-bulking agent proportion controlling conditions and by evaluating the food waste composting process when inoculated by a bacterial inoculant product compared to uninoculated compost. Three experiments were run in total. The two first experiments were conducted for 48 days with sampling at each step of composting, while the third experiment last 50 days and included one extra sampling date. In the first experiment, 50:50, 65:35 …
Impact Of Covid-19 On Arkansas Field Crop Farms, A. Durand-Murat, S. Stiles, B. Watkins, C. R. Stark Jr.
Impact Of Covid-19 On Arkansas Field Crop Farms, A. Durand-Murat, S. Stiles, B. Watkins, C. R. Stark Jr.
Research Reports and Research Bulletins
The coronavirus (COVID-19) pandemic is disrupting the global economy in unprecedented ways, and the agricultural sector is no exception. Prices of most commodities decreased since the pandemic began, which are affecting farm revenues and production costs. We assess the impact of COVID-19 on Arkansas field crop farms using the Representative Farm models, calibrated to the latest baseline published by the Food and Agricultural Policy Research Institute. The results show that COVID-19 decreases the net cash farm incomes of all five farms, increases the probability of having a negative net cash farm income, and increases the cost of commodity programs. Payments …
Relationship Between University Student Characteristics And Water Conservation Behaviors, Matthew A. Wise
Relationship Between University Student Characteristics And Water Conservation Behaviors, Matthew A. Wise
Graduate Theses and Dissertations
Water over-consumption is a critical issue due to it being a mismanaged, and virtually finite, natural resource. In order to convey this information to the public and promote change, it is important to understand the public’s current attitude towards the topic in order to develop more targeted teaching approaches. The purpose of this study was to determine college-age students’ perceptions about water resource usage, their personal levels of active engagement in water conservation, and if any differences existed between agriculture students and non-agriculture students. This study utilized an online quantitative survey, guided by the Theory of Planned Behavior, which was …
The Economics Of On-Farm Rice Drying In Arkansas, Clayton Parker
The Economics Of On-Farm Rice Drying In Arkansas, Clayton Parker
Agricultural Economics and Agribusiness Undergraduate Honors Theses
Globally, rice producers are faced with the temporal problem of deciding the optimal time to being rice harvest. When harvested, paddy rice is typically at a moisture content (HMC) between 15 and 22%. Upon delivery, the rice is subsequently dried by the mill to a moisture content (MC) of 12.5%. Riceland Foods Inc., the largest miller of rice in the world, uses a stair-step pricing model to charge farmers to dry in price/unit as the MC of grain decreases from a range of +22% to 13.5%. This study estimates an alternative linear relationship in the stair-step model to determine MC …
Evaluation Of The Arkansas Double Up Food Bucks Program, Colton G. Henderson
Evaluation Of The Arkansas Double Up Food Bucks Program, Colton G. Henderson
Graduate Theses and Dissertations
Fruit and vegetable consumption is particularly low in Arkansas with only a small percentage of residents meeting daily recommendations. Arkansas also has one of the highest percentages of food insecurity and obesity in the United States. Low-income households, such as Supplemental Nutrition Assistance Program (SNAP) recipients, are at a higher risk of these issues. Financial assistance programs have been implemented to help in aiding these problems. The Double Up Food Bucks program (DUFB) is one of these programs. DUFB provides matching financial vouchers for SNAP benefits recipients spend on fresh local produce at participating grocery stores and farmers’ markets. The …
The Impact Of Income On Nutrition: A Case Study Of Northern Mozambique, Hunter Swanigan, Lawton Lanier Nalley
The Impact Of Income On Nutrition: A Case Study Of Northern Mozambique, Hunter Swanigan, Lawton Lanier Nalley
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
In 2017, Mozambique ranked as one of the least developed countries in the world by measures of health, education, and income. With a minimal annual income, purchasing adequate food to meet recommended levels of nutrients for a healthy diet is difficult, leaving 40% of the country undernourished. This study analyzed what foods are available during the dry months (hungry season) of May through October in the Nampula province of Mozambique to determine if it is possible to meet recommended levels of nutrients from purchasing and growing food. Three different levels of income were used to determine what percentage of the …
