Role Of Clover "Down On The Farm", Don Sorrell

Forage Symposium at the Kentucky Cattlemen’s Convention

In an effort to evaluate the Role of Clover ”Down on the Farm”, a survey was developed and then e-mailed to Agriculture and Natural Resources Extension Agents in Kentucky. Agents were asked to complete the survey based on their estimate of use and importance of clover in their particular county. Thirtytwo (32) surveys were returned. The following is a summary of those returned surveys.

Establishing Clovers In Pasture And Hay Fields, Garry D. Lacefield

Forage Symposium at the Kentucky Cattlemen’s Convention

Pasture renovation means to renew and improve. In Kentucky, this usually means adding lime and fertilizer, controlling weeds and insects and planting a legume such as red clover and/or white clover. The primary benefits come as a result of getting legumes established in grass-dominated fields.

Estimating Clover Percentage In Your Pasture, S. Ray Smith

Forage Symposium at the Kentucky Cattlemen’s Convention

You often hear Extension Agents and Extension Specialists talk about how important it is to add clover to your grass pastures. We talk about the advantage of free nitrogen, the added forage quality and yield, the benefit of diluting the toxic effects of tall fescue, and many other benefits. Usually after I give a presentation promoting all the benefits of clover the first question from the audience is, “How much clover do I need?” My standard answer is that 30 to 40% clover provides many of these benefits without compromising grass productivity. In fact, 30 to 40% clover in a …

Why Grow Clovers?, Don Ball, Garry D. Lacefield

Forage Symposium at the Kentucky Cattlemen’s Convention

Clovers have long been viewed as being special and beneficial pasture plants, but recently the incentives livestock producers have to grow them have further increased. Why are many people more interested than ever in growing clovers in pastures as companion species with grasses? Here are several reasons that collectively make a compelling case.

Maria Sibylla Merian's Frogs, Kay Etheridge

Biology Faculty Publications

Maria Sibylla Merian (German, 1647-1717) is best known for her magnificent 1705 publication, Metamorphosis insectorum surinamensium, although she published earlier works on insect metamorphosis. Merian wrote the text and painted all of the illustrations for her books, and for the early volumes she produced most of the engravings. Contemporary scholarship has focused primarily on Merian's detailed images of lepidopteran and host plant life cycles, but Merian's Surinam album also portrays anuram metamorphosis, including the first European depiction of Pipa pipa.

Combining A Dispersal Model With Network Theory To Assess Habitat Connectivity, Todd R. Lookingbill, Robert H. Gardner, Joseph R. Ferrari, Cherry E. Keller

Geography and the Environment Faculty Publications

Assessing the potential for threatened species to persist and spread within fragmented landscapes requires the identification of core areas that can sustain resident populations and dispersal corridors that can link these core areas with isolated patches of remnant habitat. We developed a set of GIS tools, simulation methods, and network analysis procedures to assess potential landscape connectivity for the Delmarva fox squirrel (DFS; Sciurus niger cinereus), an endangered species inhabiting forested areas on the Delmarva Peninsula, USA. Information on the DFS’s life history and dispersal characteristics, together with data on the composition and configuration of land cover on the peninsula, …

Impact Of Weed Management Practices On Grapevine Growth, Yield Components, Plant And Arthropod Abundance, And Carabid Seed Predation In Paso Robles Vineyard, Paolo Sanguankeo

Master's Theses

In the Central Coast of California, USA, wine grape growers are making efforts to identify weed control practices that promote biodiversity in their vineyards while maintaining yields. A field study was conducted in Paso Robles, CA in 2006 and 2007 evaluating the effect on Zinfandel grape-vine growth and production, groundcover plant, and ground dwelling arthropod communities of five weed control practices: 1) flumioxazin, 2) simazine, 3) cultivation, 4) cover crop, and 5) untreated control.

The herbicide treatments had the lowest weed biomass followed by the cultivation, being approximately 10 and 2 times lower than the weed biomass of either the …

Biofuels: Cultivating Energy, Not Invasive Species, Invasive Species Advisory Committee

National Invasive Species Council

Biofuels: Cultivating Energy, not Invasive Species, approved by ISAC on August 11, 2009

ISSUE

To provide alternatives to petroleum-based energy, the United States government has mandated a greater proportion of plant-based biofuels be integrated into its energy portfolio. However, certain plant species being proposed for biofuel production in the United States are invasive species or are likely to escape cultivation and become invasive. United States Executive Order (EO) 131121 defines invasive species as “alien [non-native] species whose introduction does or is likely to cause economic or environmental harm or harm to human health” and states: “Each Federal agency whose actions …

Mangrove-Exported Nutrient Incorporation By Sessile Coral Reef Invertebrates, Elise F. Granek, Jana E. Compton, Donald L. Phillips

Environmental Science and Management Faculty Publications and Presentations

Coastal mangrove forests were historically considered as a source of organic matter (OM) for adjacent marine systems due to high net primary production; yet recent research suggesting little uptake through the food web because of low nutritional quality, challenges the concept of trophic linkage between mangrove forests and coral reefs. To examine the importance of mangrove forests to coral reef nutrient availability, we examined sessile reef-forming invertebrate consumers including hard corals, sponges, a bivalve mollusc, polychaete annelid and tunicate, and potential sources of OM (decaying mangrove leaves, microalgae, macroalgae, and seagrass) in Bocas del Toro, Panama. Using stable isotope analyses …

Management Of Merino Weaners For Optimum Production, Patricia Harper, Keith Croker, Danny Roberts

Bulletins 4000 -

Sheep mortality during the first year of life is a large problem on many farms and poses a significant animal welfare issue for Australian agriculture. Post weaning mortality is estimated to cost the Australian sheep industry more than $89 million annually through reduced income, poor productivity and increased management expenses (Sackett et al. 2006).

A high mortality rate among weaners reduces the number of surplus animals available for sale and the number of potential breeding replacements. This, in turn, affects the selection intensity for desirable traits and the flock’s rate of genetic improvement.

Ill thrift and poor growth of weaner …

Extending Grazing And Reducing Stored Feed Needs, Don Ball, Edward N. Ballard, Mark Kennedy, Garry D. Lacefield, Dan Undersander

Forage Symposium at the Kentucky Cattlemen’s Convention

Why extend the grazing season? For most livestock producers, extending the grazing season for their animals, or otherwise filling gaps in pasture forage availability to reduce stored feed needs, should be a high priority objective.

Teff: What Is It? Where Does It Fit In Kentucky, Bret Winsett

Forage Symposium at the Kentucky Cattlemen’s Convention

Teff (Eragrostis tef (zucc)) is an annual, warm season grass native to Ethiopia. Throughout its history, teff has been used more as a gluten-free grain for flour than as forage. However, in recent years, forage agronomists and producers have become increasingly interested in its potential contribution as a hay crop. Teff is characterized by a fairly large crown, many tillers, fine stems, a very shallow root system, rapid growth and high tonnage capability. During the vegetative stage, teff plants look somewhat similar to tall fescue in size and color. Teff tends to germinate quickly with good moisture, regrow quickly after …

Weed Control Options For Pastures, Jon Doran

Forage Symposium at the Kentucky Cattlemen’s Convention

What is a weed? A pasture or hayfield “weed” is any plant that you deem as being out of place and/or a plant that is decreasing your desired forage production. Weeds may be classified in several ways including broadleaf weeds, woody plants, and undesirable grasses. Besides decreasing forage, weeds can also interfere with forage utilization, grazing distribution, etc. There are several methods available to control weeds and increase production of and access to desirable forages. The three main methods are cultural, mechanical, and chemical. The cultural method is quite simple-a thriving grass stand is an excellent form of weed control …

Selecting Clover Varieties Wisely, S. Ray Smith

Forage Symposium at the Kentucky Cattlemen’s Convention

Although there are not a lot of new red clover varieties, several companies and Universities have active red clover breeding programs. In some ways, red clover is the easiest species to make variety recommendations for. Simply put, “only plant certified seed of improved varieties, never plant common seed.” University of Kentucky research has shown that the difference between improved varieties and common seed can be 6000 to 10,000 lb/acre in higher yield and 1 to 1 ½ years longer stand life. Sometimes you may “luck up” and find that the bag of cheap common seed you purchased was actually an …

Curing Nature-Deficit Disorder: How Environmental Education Helps Kids Learn, Jamie Leigh Langley

Mahurin Honors College Capstone Experience/Thesis Projects

Walk into any public school and talk with the children about their experiences in nature and you will begin to see a pattern. Children have made few connections with the world around them. They do not spend much time outdoors and the time they do spend outdoors is not spent interacting directly with nature. Why does this matter? Look at these same kids and you will see another pattern emerging: Attention-Deficit Disorder, depression, obesity, emotional problems, etc. While not all of these problems are directly caused by a lack of interaction with the natural world, current research shows that there …
