Legacy Effects Of Long-Term Nitrogen Fertilizer Application On The Fate Of Nitrogen Fertilizer Inputs In Continuous Maize, Hanna J. Poffenbarger, John E. Sawyer, Daniel W. Barker, Daniel C. Olk, Johan Six, Michael J. Castellano 2018 Iowa State University

Legacy Effects Of Long-Term Nitrogen Fertilizer Application On The Fate Of Nitrogen Fertilizer Inputs In Continuous Maize, Hanna J. Poffenbarger, John E. Sawyer, Daniel W. Barker, Daniel C. Olk, Johan Six, Michael J. Castellano

Agronomy Publications

Nitrogen fertilizer management can impact soil organic C (SOC) stocks in cereal-based cropping systems by regulating crop residue inputs and decomposition rates. However, the impact of long-term N fertilizer management, and associated changes in SOC quantity and quality, on the fate of N fertilizer inputs is uncertain. Using two 15-year N fertilizer rate experiments on continuous maize (Zea mays L.) in Iowa, which have generated gradients of SOC, we evaluated the legacy effects of N fertilizer inputs on the fate of added N. Across the historical N fertilizer rates, which ranged from 0 to 269 kg N ha−1 yr ...


Exploring Multiple Operating Scenarios To Identify Low-Cost, High Nitrate Removal Strategies For Electrically-Stimulated Woodchip Bioreactors, Ji-Yeow Law, Michelle L. Soupir, D. Raj Raman, Thomas Moorman 2018 Iowa State University

Exploring Multiple Operating Scenarios To Identify Low-Cost, High Nitrate Removal Strategies For Electrically-Stimulated Woodchip Bioreactors, Ji-Yeow Law, Michelle L. Soupir, D. Raj Raman, Thomas Moorman

Agricultural and Biosystems Engineering Publications

Woodchip bioreactors are recognized as an effective best management practice in the Iowa Nutrient Reduction Strategy. This edge-of-field practice intercepts and removes NO3-N, thereby reducing the NO3-N concentration in tile drainage before being discharged into surface water. Actual NO3-N load reductions realized by woodchip bioreactors are impacted by bioreactor size, hydraulic retention time (HRT), and denitrification efficiency. A typical woodchip bioreactor in Iowa may have 0.07% bioreactor area with respect to treatment area, 4–8 h HRT, and 43% mean denitrification efficiency. Here, we explored the potential of using electrically stimulated woodchip bioreactors to achieve greater NO3-N removal, and ...


The Relationship Of Male And Female Pastoralist Income With Household Food Security And Nutrition Status In Tanzania: Maasai, Sukuma, And Barabaig Ethnic Groups., Henriette Gitungwa 2018 University of Nebraska - Lincoln

The Relationship Of Male And Female Pastoralist Income With Household Food Security And Nutrition Status In Tanzania: Maasai, Sukuma, And Barabaig Ethnic Groups., Henriette Gitungwa

Dissertations and Theses in Agricultural Economics

Although previous work provides a significant baseline for understanding the impact of gender on household decision making and resource (i.e. income and food) allocation, there are gaps in evidence for important groups, including East African pastoralists. Previous authors have noted that pastoralists’ gender roles and relations appear to be resistant to change, potentially impeding household development. This paper attempts to assess the relationship between male and female pastoralists’ income control and household food security and nutritional status in Tanzania. We use three surveys: a household-level livestock health and economics survey, a household food security survey, and an individual woman-level ...

Louisiana Urban And Suburban Homeowners’ Fertilizer Management Behavioral Beliefs, Intentions, And Past Behaviors, Natalie Levy 2018 Louisiana State University and Agricultural and Mechanical College

Louisiana Urban And Suburban Homeowners’ Fertilizer Management Behavioral Beliefs, Intentions, And Past Behaviors, Natalie Levy

LSU Doctoral Dissertations

Nutrient runoff of nitrogen and phosphorus from improper lawn and landscape fertilization practices contributes to water quality issues within the Mississippi River drainage basin and the Northern Gulf of Mexico (NRC, 2009a; Robbins & Birkenholtz, 2003). The implementation of fertilizer best management practices has become a critical strategy for reducing nutrient runoff (Carey et al., 2012a; Carey et al., 2013; U.S. EPA, 2005). The purpose of this study was to determine if relationships exist among selected perceptual measures regarding home lawn and landscape fertilizer management practices among Louisiana urban and suburban homeowners. Ajzen’s (1991) Theory of Planned Behavior (TPB) was the theoretical framework used to study Louisiana homeowners’ fertilizer management practices. An online semantic differential questionnaire assessed homeowners’ TPB perceptual measures ...

Price Seasonality In The Catfish Value Chain In Uganda, James O. Bukenya 2018 Alabama A&M University

Price Seasonality In The Catfish Value Chain In Uganda, James O. Bukenya

Professional Agricultural Workers Journal

Seasonal patterns in production and demand are common in many agricultural markets. Charting these patterns provides information that complements fundamental and technical analyses. It is in this spirit that this paper seeks to examine price seasonality in the catfish value chain in Uganda. The analysis draws on monthly prices taken from secondary source recorded data and uses moving average index to chart price patterns. The results reveal distinct seasonal patterns in the farm-gate, ex-vessel, retail, and wholesale market channels. Across market channels, the results for farm-gate versus ex-vessel prices reveal that farm-gate prices are more affected by seasonal effects compared ...
