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 Dec 2014

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 × 61 cm (W ...

Impacts Of Land-Cover Change And High Rainfall On Soil Erosion Among Three Farms In Cerro Punta, Chiriquí, Panamá., Madeline Happ Dec 2014

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 ...

Energy Value Of De-Oiled Distillers Grains Plus Solubles In Beef Cattle Diets, Meredith L. Bremer Dec 2014

Energy Value Of De-Oiled Distillers Grains Plus Solubles In Beef Cattle Diets, Meredith L. Bremer

Theses and Dissertations in Animal Science

Ethanol plants are centrifuging off oil from the thin stillage stream as it has added market value currently. The impact of oil removal on cattle performance has been minimally researched. Thus four trials, one growing, one digestion, and two feedlot, were designed to determine the energy and feeding value of de-oiled distillers grains in beef cattle diets.

In growing cattle diets, diet concentration of modified distillers grains plus solubles (MDGS) impacted cattle performance more than oil content. Ending BW, ADG, and G:F did not differ between cattle fed de-oiled or full fat MDGS, however cattle fed de-oiled MDGS had ...

Proper Handling And Transportation Of Eggs For Sale At Kentucky Farmers’ Markets, Anthony J. Pescatore, Jacquie Jacob Dec 2014

Proper Handling And Transportation Of Eggs For Sale At Kentucky Farmers’ Markets, Anthony J. Pescatore, Jacquie Jacob

Agriculture and Natural Resources Publications

Regardless of the number of eggs produced, and whether the eggs are for home use or sale, careful egg handling is very important. The United States Food and Drug Administration (FDA) lists eggs as a potentially hazardous food, therefore careful handling is important. In Kentucky, if you sell more than 60 dozen eggs a week you need to purchase a retail license. The same holds true if you want to sell your eggs to a retail store to be re-sold or to a distributor that will sell them for you. If you produce fewer than 60 dozen eggs a week ...

Basic Sheep Genetics, Debra K. Aaron Dec 2014

Basic Sheep Genetics, Debra K. Aaron

Agriculture and Natural Resources Publications

Genetics is the science of heredity. It seeks to explain differences and similarities exhibited by related individuals. The application of genetics to livestock improvement is known as animal breeding. The objective of this fact sheet is to provide a refresher course on basic genetics and to show how knowledge of genetics can be used to improve sheep production.


Keeping And Using Flock Performance Records, Debra K. Aaron Dec 2014

Keeping And Using Flock Performance Records, Debra K. Aaron

Agriculture and Natural Resources Publications

Performance records serve as the cornerstone of any good livestock management program. Unfortunately, the task of collecting, maintaining and using performance records is the one area of livestock production in general that gets the least attention. This fact sheet provides ten reasons why all sheep producers need to keep performance records on their flocks. Then, some ways of maintaining and using those records are discussed.


Sheep Breeding: Heritability, Ebvs, Epds And The Nsip, Debra K. Aaron Dec 2014

Sheep Breeding: Heritability, Ebvs, Epds And The Nsip, Debra K. Aaron

Agriculture and Natural Resources Publications

Genetic improvement in a flock depends on the producer’s ability to select breeding sheep that are genetically superior for traits of economic importance. This is complicated by the fact that an animal’s own performance is not always a true indicator of its genetic potential as a parent.


Inbreeding In Sheep, Debra K. Aaron Dec 2014

Inbreeding In Sheep, Debra K. Aaron

Agriculture and Natural Resources Publications

Inbreeding is broadly defined as the mating of individuals that are related. Strictly speaking, however, all animals within a breed are related. So, in a sense, every purebred sheep producer practices some degree of inbreeding. In most cases this relationship is very slight. Therefore, inbreeding is more practically defined as the mating of individuals more closely related than the average of the breed. This practice includes mating brother to sister, sire to daughter and son to dam.


Crossbreeding Considerations In Sheep, Debra K. Aaron Dec 2014

Crossbreeding Considerations In Sheep, Debra K. Aaron

Agriculture and Natural Resources Publications

Crossbreeding is the mating of individuals from different breeds. To a certain extent, it is a simple concept, but embarking upon a crossbreeding program, in sheep or any other livestock species, involves long-term decisions.

The primary benefits of a crossbreeding program are heterosis and breed complementarity.

Agriculture and Natural Resources Publications

Burley and dark tobacco growers in the U.S. make hundreds of decisions every growing season that impact the yield and quality of the crops that they produce. These decisions may include choosing appropriate varieties, planning effective pest control measures or perhaps deciding the best time to top or harvest a crop. Increasingly, tobacco growers are being required by the industry to record and justify their management decisions and actions. The most comprehensive example of this is the U.S. Tobacco Good Agricultural Practices (GAP) program that was initiated during the 2013 growing season and expanded in ...


Student Mindset Compared To Performance On The Nebraska State Accountability Test, Ann E. Dvorak Dec 2014

Student Mindset Compared To Performance On The Nebraska State Accountability Test, Ann E. Dvorak

Theses, Dissertations, & Student Scholarship: Agricultural Leadership, Education & Communication Department

Carol Dweck’s research on fixed vs. growth mindset has led to many opportunities for educational research. According to Dweck, a person with a fixed mindset believes that his or her qualities related to a certain task are unchangeable while an individual with a growth mindset believes that his or her qualities related to a certain task can be changed and improved (Dweck, 2006). A correlative study was conducted to identify relationships that exist between student mindset and scores from the Nebraska State Accountability Test (NeSA). For this study, students in the 7th, 8th, and 11th grade ...

Agronomy Publications

Maize- and prairie-based systems were investigated as cellulosic feedstocks by conducting a 9 ha side-by-side comparison on fertile soils in the Midwestern United States. Maize was grown continuously with adequate fertilization over years both with and without a winter rye cover crop, and the 31-species reconstructed prairie was grown with and without spring nitrogen fertilization. Both maize stover and prairie biomass were harvested in the fall. We compared amounts of cellulosic biomass produced and harvested, carbohydrate contents as measured by both dietary and detergent methods, and estimated cellulosic ethanol yields per hectare. From 2009–2013, the cropping system with the ...
