Faculty Work Comprehensive List

Summary presentation of research conducted over a 5 year period to determine which cropping systems best reduce nitrate leaching. Initial data was collected on nitrate concentration from individual wells in the Sioux Center, Iowa area which led to connections with the Iowa Department of Natural Resources Source Water Protection Program. A community group was then formed comprised of city representatives, Dordt College faculty, local farmers, Source Water Protection Program staff, and others. The group applied for and received a Leopold Center for Sustainable Agriculture grant to fund field experiments to identify cropping systems that retain nitrate and are workable for …

Tall Fescue Seed Extraction And Partial Purification Of Ergot Alkaloids, Huihua Ji, Franklin Fannin, J. Klotz, Lowell P. Bush

Kentucky Tobacco Research and Development Center Faculty Publications

Many substances in the tall fescue/endophyte association (Schedonorus arundinaceus/Epichloë coenophiala) have biological activity. Of these compounds only the ergot alkaloids are known to have significant mammalian toxicity and the predominant ergot alkaloids are ergovaline and ergovalinine. Because synthetically produced ergovaline is difficult to obtain, we developed a seed extraction and partial purification protocol for ergovaline/ergovalinine that provided a biologically active product. Tall fescue seed was ground and packed into several different sized columns for liquid extraction. Smaller particle size and increased extraction time increased efficiency of extraction. Our largest column was a 114 × 52 × …

Impacts Of Land-Cover Change And High Rainfall On Soil Erosion Among Three Farms In Cerro Punta, Chiriquí, Panamá., Madeline Happ

Independent Study Project (ISP) Collection

Soil erosion is a key source leading to the depletion of Earth’s natural resources. Beginning with deforestation, soils are stripped of their rich vegetation cover, leaving them vulnerable to wind, water, and sometimes total exhaustion. One of the major causes of deforestation, if not the primary cause, is for agricultural purposes. Extensive agricultural fields, steep slopes, and heavy rains characterize the highlands of Chiriquí; thus, the land displays potential for severe loss of soil. This paper illustrates and discusses the extent of soil erosion in Cerro Punta, Chiriquí, specifically considering the steep terrains and very wet environment that impact the …

Metabolic Engineering Of Oilseed Crops To Produce High Levels Of Novel Acetyl Glyceride Oils With Reduced Viscosity, Freezing Point And Calorific Value, Jinjie Liu, Adam Rice, Kathleen Mcglew, Vincent Shaw, Hyunwoo Park, Thomas E. Clemente, Mike Pollard, John Ohlrogge, Timothy P. Durrett

Department of Agronomy and Horticulture: Faculty Publications

Seed oils have proved recalcitrant to modification for the production of industrially useful lipids. Here, we demonstrate the successful metabolic engineering and subsequent field production of an oilseed crop with the highest accumulation of unusual oil achieved so far in transgenic plants. Previously, expression of the Euonymus alatus diacylglycerol acetyltransferase (EaDAcT) gene in wild-type Arabidopsis seeds resulted in the accumulation of 45 mol% of unusual 3-acetyl-1,2- diacyl-sn-glycerols (acetyl-TAGs) in the seed oil (Durrett et al., 2010 PNAS 107:9464). Expression of EaDAcT in dgat1 mutants compromised in their ability to synthesize regular triacylglycerols increased acetyl-TAGs to 65 mol%. Camelina and soybean …

Health Professionals’ Roles In Animal Agriculture, Climate Change, And Human Health, Aysha Z. Akhtar, Michael Greger, Hope Ferdowsian, Erica Frank

Michael Greger, MD, FACLM

What we eat is rapidly becoming an issue of global concern. With food shortages, the rise in chronic disease, and global warming, the impact of our dietary choices seems more relevant today than ever. Globally, a transition is taking place toward greater consumption of foods of animal origin, in lieu of plantbased diets. With this transition comes intensification of animal agriculture that in turn is associated with the emergence of zoonotic infectious diseases, environmental degradation, and the epidemics of chronic disease and obesity. Health professionals should be aware of these trends and consider them as they promote healthier and more …

Root Stimulation Using Vermi-Products In Grape Vine Propagations, Katerina M. Flores

Wine and Viticulture

Vermi-products are byproducts produced from earthworms digesting and decomposing a natural material into another. Liquid teas or extracts of vermi-products are another form of leachate material found in the completed compost bin. These products are not high in essential plant macronutrients, have an average neutral pH (around 7.0), and are known for living microbial population. Grapevine propagations cut from the Trestle Vineyard at California Polytechnic State University, San Luis Obispo were used to observe root growth development using steer compost, vermicompost, and vermi-extract. Propagations used were dormant Pinot Noir clone 777. Compost subsamples tested 5%, 10%, 20%, and 40% by …

Agricultural Experiences And Factors Of Undergraduates Who Enroll In A College Of Agriculture, Benjamin G. Swan, Ann M. De Lay

Agricultural Education and Communication

Industry partners and College of Agriculture, Food and Environmental Sciences (CAFES) faculty have observed students entering the college possessed fewer agriculture experiences and skills than their predecessors. They have also lamented the increasing pressure to develop industry-ready students, when the gaps are ever wider between their experience and skills entering college and what are required upon graduation. During the 2011 spring quarter, all CAFES students (N = 3,366) were sent an electronic survey that resulted in 911 responses (27% response rate). Three quarters of the students were female and one third were seniors. Prior to enrolling at the university, 34% …

This is especially important considering California is number one producer of agricultural commodities in the United States.

The Central Coast is defined as these three counties: Monterey County, San Luis Obispo County, and Santa Barbara County. An online survey was developed and sent …

Groundwater Trend Analysis And Salinity Risk Assessment For The South-West Agricultural Region Of Western Australia, 2007–12, G Paul Raper, Russell Speed, John Andrew Simons, A L. Killen, Andrew Blake, A T. Ryder, Rosemary H. Smith, Grant Stainer, L Bourke

Resource management technical reports

Dryland salinity is a hydrologically driven land degradation hazard in the south-west agricultural region of Western Australia (WA). Shallow-rooted annual crops and pastures transpire significantly less water than the native vegetation they replaced, leading to an increase in recharge, rising groundwater levels and the development of shallow watertables in areas where often none existed previously. Rising groundwater levels mobilise soluble salts, naturally stored at high concentrations in the regolith. These salts can be concentrated in the root zone of vegetation by evapotranspiration.

Grain Iron And Zinc Density In Pearl Millet: Combining Ability, Heterosis And Association With Grain Yield And Grain Size, Mahalingam Govindaraj

Mahalingam Govindaraj

Genetics of micronutrients and their relationships with grain yield and other traits have a direct bearing on devising effective strategies for breeding biofortified crop cultivars. A line × tester study of 196 hybrids and their 28 parental lines of pearl millet (Pennisetum glaucum (L.) R.Br.) showed large genetic variability for Fe and Zn densities with predominantly additive gene action and no better-parent heterosis. Hybrids with high levels of Fe and Zn densities, involved both parental lines having significant positive general combining ability (GCA), and there were highly significant and high positive correlations between performance per se of parental lines and …
