Can Soil Phosphorus Sorption Saturation Estimate Future Potential Legacy Phosphorus Sources?, A. N. Sharpley, K. R. Brye, J. M. Burke, L G. Berry, M. B. Daniels, P. Webb

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

Various soil extraction methods are used to indicate plant available P in soil but do not account for soil specific sorption of subsequent applications of P. Thus, estimates of soil phosphorus sorption saturation (PSS; estimated from Mehlich-3 extractable P, Al, and Fe) have been used in conjunction with Mehlich-3 extractable soil phosphorus (M3P) to overcome these limitations. As less is known about the effect of land management on PSS than M3P under field conditions, the effect of field management on PSS was investigated for three pastures over 5 yr (2014-2018). Swine slurry was applied to two fields (Field 1 received …

Grain and Other Field Crops Research Articles

Deep sands on the south coast sandplain of Western Australia (WA) have multiple soil constraints including water repellence, high soil strength, low nutrient levels and subsoil acidity. The aim of the study was to test contrasting methods of managing water repellence and to assess their impacts on one or more soil constraints to crop production. These methods included seeding tyne design (knife point, winged points, paired row), soil wetting agent addition, strategic inversion tillage (rotary spading, mouldboard ploughing to 0.35 m) and clay-rich subsoil addition (170 t ha−1 with incorporation by spading to 0.20 or 0.35 m). Limesand (2 t …

Market Trends In Food Consumption Expenditures Away From Home Prior To The Covid-19 Pandemic, Rebecca Weir

Undergraduate Economic Review

U.S. food consumption expenditures away from home increased from 19 percent of total food expenditures in 1955 to 48 percent in 2015. Simultaneously, female participation in the labor force grew by 52.7 million women from 35 to 57 percent, signifying increased opportunity cost for women to prepare meals at home. This research uses an ordinary least squares regression to examine socioeconomic factors influencing the rise in U.S. food consumption expenditures away from home in 2018. Results inform food production and service industries’ marketing strategies, and set the stage for whether a new pattern emerges in response to the COVID-19 pandemic.

Urban Agriculture In Asia To Meet The Food Production Challenges Of Urbanization: A Review, Onyekachukwu Akaeze, Dilip Nandwani

Agricultural and Environmental Sciences Faculty Research

Urban expansion in Asia is concentrated in metropolitan areas. This has adversely affected in-city food production by decreasing farmlands in and around urban centers. Asian countries have experienced fast disappearance of urban-fringe farmland which at some point provided 70% of the vegetables consumed by the city's population. Uneven distribution of incomes, along with an increase in urban poverty, has further exacerbated the already critical problems of low quantity and quality and high prices of wholesome food. In India, it is estimated that five out of every six urban families typically spend 70% of their income on food. The United Nations …

Dairy Product Purchasing In Households With And Without Children, Mario Ortez, Courtney Bir, Nicole Olynk Widmar, Jonathan Townsend

Department of Agricultural Economics Faculty Publications

Dairy products are considered a staple in the American diet due in part to their nutritious content and appealing flavor. Consumption patterns may differ among age segments influenced by preferences for fat content and taste in dairy. Furthermore, having children in their household may influence the amount, frequency, and type of dairy products that a consumer chooses to purchase. This study finds that households that frequently bought food for children generally purchased larger quantities of fluid milk and more fluid milk with a higher fat content. Households with children also bought yogurt more frequently than other households. Labeling information of …

Distillers Grains Pre, During, And Post Covid-19: Ongoing Recovery And Structural Demand Implications, Daniel Gertner, Elliott James Dennis

Cornhusker Economics

Prior to the shutdowns caused by the COVID-19 pandemic, distillers grains and other co-products of ethanol production played a crucial role in maintaining the rev-enue stream of dry mill ethanol plants (Irwin 2020). With low crude oil prices over the last half of the decade and corn prices holding steady over the same period of time, the margin for error in the ethanol industry was thin. More than a third of Nebraska’s ethanol plants either temporarily or permanently closed in 2019 (MacroTrends 2020); (York News Times 2019). To prevent similar outcomes, ethanol plants focused on diver-sifying their operations to produce …

Mechanistic Insights Into Strigolactone Biosynthesis, Signaling And Regulation During Plant Growth And Development, Kaiser Iqbal Wani, Andleeb Zehra, Sadaf Choudhary, M Naeem, M. Masroor A. Khan, Christian Danve Castroverde, Tariq Aftab

Biology Faculty Publications

Strigolactones (SLs) constitute a group of carotenoid-derived phytohormones with butenolide moieties. These hormones are involved in various functions, including regulation of secondary growth, shoot branching and hypocotyl elongation, and stimulation of seed germination. SLs also control hyphal branching of arbuscular mycorrhizal (AM) fungi, and mediate responses to both abiotic and biotic cues. Most of these functions stem from the interplay of SLs with other hormones, enabling plants to appropriately respond to changing environmental conditions. This dynamic interplay provides opportunities for phytohormones to modulate and augment one another. In this article, we review our current mechanistic understanding of SL biosynthesis, receptors …

Coal Char Affects Soil Ph To Reduce Ammonia Volatilization From Sandy Loam Soil, Dinesh Panday, Maysoon M. Mikha, Bijesh Maharjan

Department of Agronomy and Horticulture: Faculty Publications

Ammonia (NH₃) volatilization loss adversely affects N availability in soil-plant systems, reduces crop yield, and negatively impacts environment. Char (coal combustion residue), which contains up to 293 g kg⁻¹ total C by weight, has been shown to reduce NH₃ volatilization due to its considerably high surface area and cation exchange capacity. The NH₃ loss can be greatly affected by a shift in soil pH or urea hydrolysis. A 21-d laboratory study was conducted to evaluate the effects of char on soil pH, N transformations, and subsequent NH₃ volatilization in sandy loam soil. Two …

Tall fescue (Schedonorus arundinaceus) is a cool-season perennial grass that is widely used as a forage for many livestock species including sheep. An endophyte (Neotyphodium coenophialum) in tall fescue produces ergot alkaloids that enhance plant survival but produce toxicosis in animals. The objective of this study was to investigate the rumen microbiota from gestation and lactation in ewes grazing tall fescue pastures with high (HA) or moderate (MA) levels of endophyte infection, and their relationship with serum parameters. Data were collected at the beginning of the study (d1), the week before initiation of lambing (d51), and at …

Preserving Cultural Heritage Through The Valorization Of Cordillera Heirloom Rice In The Philippines, Subir Bairagi, Marie Claire Custodio, Alvaro Durand-Morat, Matty Demont

Agricultural Economics and Agribusiness Faculty Publications and Presentations

For centuries, heirloom rice varieties have been grown on the terraces of the Cordillera Mountains of Luzon, Philippines, terroirs known for their significant historical, cultural, and aesthetic values. However, heritage heirloom rice farming is gradually being abandoned, mainly because of its lower productivity and the struggle of the sector to create a sustainable niche market for heirloom rice by branding its cultural, social, and nutritional values. We propose several demand-side intervention strategies for the valorization of heirloom rice. To support the development of a segmented marketing strategy for heritage farming, we provide evidence on urban consumers’ willingness to purchase heirloom …
