Chemical Oxygen Demand Reduction Using The Algae Dunaliella Primolecta And Chlorella Vulgaris, Angeles L. Mora, Alejandro Hernandez, Alejandro Calderón-Urrea

STAR Program Research Presentations

Farm industry wastewater is characterized by high organic materials and by high chemical oxygen demand (COD). Farms with large livestock and poultry operations can be a major source of wastewater thus a major concern for effective environmental and industrial management. Effective environmental and industrial management are high in cost therefor biofuels produced from plants have a potential of replacing a portion of fossil fuel consumption with a renewable efficient alternative. Due to California’s water crisis in the recent years, it is questioned if a biological treatment system that uses algal growth to create renewable energy in the form of biodiesel …

Turfgrasses Of Kentucky, Gregg Munshaw

Agriculture and Natural Resources Publications

Roughly 7,500 grass species are grown around the world, but only 14 species are adapted as turfgrasses that have been used extensively. Kentucky is situated in the transitional climatic zone of the United States, the middle point between the cool north and the warm south, with warm summers and cool winters. Because of its unusual climate, no single grass is suitable for all situations and locations.

The Potential For Reducing N Fertilizer Inputs For Corn Production In The First Year Following Alfalfa, Earl Creech, Grant Cardon, James Barnhill, Jody Gale, Clark Israelsen, Boyd Kitchen, Mark Nelson, Mike Pace

All Current Publications

The objectives of the project reported in this fact sheet were to 1) examine current post-alfalfa N fertilizer credit guidelines and investigate the potential to further reduce N fertilizer rates (if possible) on first year corn after alfalfa across Utah, and 2) accordingly update the USU Extension corn management recommendations and promote grower awareness and adoption of the new guidelines.

Irrigated Alfalfa Variety Performance, 2011-2014; North Logan, Utah, Earl Creech, Thomas Griggs, Clark Israelsen, T J Bingham, Jason Clark, Mark Pieper

All Current Publications

Alfalfa is the most important crop in Utah, both in terms of acreage and revenue. Although often overlooked, one of the most critical decisions made in alfalfa production is determining which variety to plant. This fact sheet summarizes dry matter (DM) yields of alfalfa varieties during 4 years at the Utah Agricultural Experiment Station Greenville Farm in North Logan (Cache Co.).

Spider Mites In Corn, Alice Ruckert, Ricardo Ramirez, Clark Israelsen

All Current Publications

This fact sheet provides information about Banks grass mites and two-spotted spider mites, important agricultural pests of corn and a wide variety of other crop, garden, and landscape plants. It includes how to identify them, their life cycle, crop injury, and management strategies.

Nitrogen And Water Effects On Canopy Sensor Measurements For Site-Specific Management Of Crops, Nicholas C. Ward

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Water and nitrogen (N) are undoubtedly the two largest agricultural inputs globally. Coupled with advances in site-specific management technology their integration into production agriculture will allow for the most efficient use these crop input resources. Active canopy sensors offer the ability to measure biophysical plant traits rapidly and make assessments about plant status. Specifically, optical sensor measurements of light reflectance assess plant N status allowing for in-season and on-the-go N recommendations and applications; while infrared thermometers (IRT) measurement of canopy temperature can be used a tool for irrigation management. To evaluate how these technologies work among different plant stress environments …

The meeting lasted 2 hours 44 minutes, and the Board went into Executive Session after the meeting was adjourned.

Land Use And Water And Soil Management Practices Impacts On Potential Groundwater Recharge In Loess Regions Of South Central Nebraska, Gustavo Bosch-Rubia

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Sustainability of agro-ecosystems must consider land use and water and soil management effects on groundwater recharge. Water flow beneath the plant root zone through the intermediate vadose zone determines potential groundwater recharge. Different land uses, water and soil management practices control deep percolation as a result of changes on evapotranspiration and infiltration. This study of the impact of surface activities on deep percolation was conducted at six locations across Nebraska: Two center-pivot irrigated no-till planting systems fields were compared with one tilled center-pivot irrigated field, a furrow irrigated field with multiple tillage treatments, an eco-fallow dryland farming system, and a …

Cash Rent Increases When Is The Right Time To Give Up A Lease?, Tina Barrett

Cornhusker Economics

There has been considerable talk for many years about the increases in cash rent. This chart shows the data collected by Nebraska Farm Business, Inc. for the average cash rent paid in the prior 10 years. The average cost has doubled from $127.71 in 2005 to $258.11 in 2014 (peak of $274.74 in 2013) . The cost now accounts for 31% of the total cost of growing irrigated corn. It's no wonder that in times of narrowing margins, producers are considering ways to reduce this major expense.

Export Taxes And Their Effects On Farmers' Profitability And Risk In Argentina, Ezequiel M. Villamil

Department of Agricultural Economics: Dissertations, Theses, and Student Research

This main objective of this thesis is to analyze the effects of export taxes on the risk faced by farmers in different regions of Argentina in their cropping operations for wheat, sunflower, soybeans and corn. In the first chapter we introduce the variables and explain the agricultural environment in Argentina. A set of three profit function models with different export tax policies were specified in a Monte Carlo simulation template using data from 1985 to the present. A set of risk measures for the upper and lower partial moments along with the overall probability distribution statistics are used to asses …

Occurrence Of An Herbicide-Resistant Plant Trait In Agricultural Field Margins, Karla L. Gag, David J. Gibson, Bryan G. Young, Julie M. Young, Joseph L. Matthews, Stephen C. Weller, Robert G. Wilson

Department of Agronomy and Horticulture: Faculty Publications

Agricultural environments allow study of evolutionary change in plants. An example of evolution within agroecological systems is the selection for resistance to the herbicide glyphosate within the weed, Conyza canadensis. Changes in survivorship and reproduction associated with the development of glyphosate resistance (GR) may impact fitness and influence the frequency of occurrence of the GR trait. We hypothesized that site characteristics and history would affect the occurrence of GR C. canadensis in field margins. We surveyed GR occurrence in field margins and asked whether there were correlations between GR occurrence and location, crop rotation, GR crop trait rotation, crop type, …
