The contributions of soil fertility and fertilizers are major production factors in all Arkansas crops. The studies contained within will allow producers to compare their practices with the university’s research efforts. Additionally, soil test data and fertilizer sales are presented to allow comparisons among years, crops, and other areas within Arkansas.

Alfalfa Disease Management, Paul Vincelli

Kentucky Alfalfa and Stored Forage Conference

Alfalfa can be a vigorous and productive forage crop for Kentucky farmers. Like all farm crops, however, alfalfa is subject to infectious diseases that can limit forage production. Managing these diseases is an important part of economical alfalfa production.

Weed Management In Alfalfa, Jonathan D. Green

Kentucky Alfalfa and Stored Forage Conference

The importance of weed control in forage production should not be overlooked, especially when you consider the high investment associated with alfalfa and other legume forages. Weed management strategies in forage legumes should first focus on cultural practices and then on chemical weed control options. Vigorous, densely growing forage legume stands tend to have fewer weed problems. Thus, cultural and management practices that promote a highly competitive forage stand help prevent many weed problems. These practices include: 1) liming and fertilizing fields based on soil test recommendations; 2) seeding well-adapted, vigorous, and long-lived varieties; 3) buying weed-free seed; 4) cutting …

Producing Quality Alfalfa Hay, Jimmy C. Henning, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

Hay is one of the most versatile of stored forages in that (1) it can be kept for long periods of time with little loss of nutrients if protected from weather; (2) a large number of crops can be successfully used for hay production; (3) it can be produced and fed in small or large amounts; (4) it can be harvested, stored and fed by hand or the production and feeding can be completely mechanized; and (5) hay can supply most nutrients needed by many classes of livestock. Hay is, therefore, the most commonly used stored feed on most farms.

Forage Testing & Marketing Program, Allen Johnson

Kentucky Alfalfa and Stored Forage Conference

Two thousand and three marks the 141^th year for the Kentucky Department of Agriculture for testing forages. We continue to strive to offer a quality service to producers at the very least cost possible. After all these years we continue to charge only $10.00 per lot or cutting and have expanded our services to try to meet the needs of our forage and livestock producers. In January 2002, we introduced the testing of haylages and have expanded this to cover most of the haylage crops harvested in Kentucky. In cooperation with The University of Kentucky Extension Service, the department …

Buying And Selling Alfalfa Hay, Garry D. Lacefield, Jimmy C. Henning

Kentucky Alfalfa and Stored Forage Conference

Alfalfa hay is an important agricultural product. Although often fed on the farms where it is produced, much alfalfa hay is also sold as a cash crop. It often constitutes a major source of income for those who sell it, or a major expense for those who buy it. Such transactions involve billions of dollars nationwide each year.

Alfalfa Haylage And Silage, Michael Collins

Kentucky Alfalfa and Stored Forage Conference

Even with extended grazing systems, typical winter weather conditions in Kentucky necessitate the production of some stored forage for livestock during winter. Hay has traditionally been the way of storing this forage. However, when rain occurs during haymaking operations, the losses can be severe both in yield and in forage quality. Harvest losses are greatest for very dry forage and are low for very wet material like direct cut silage. Silage offers an opportunity to avoid most of the rain damage during harvest because the crop only needs to be left out overnight in most cases to be ready to …

Alfalfa And Mrls: What We Know After One Year Of Testing, Jimmy C. Henning, Wayne Long

Kentucky Alfalfa and Stored Forage Conference

The onset of mare reproductive loss syndrome in April 2001 in Kentucky lead to much speculation about its cause. Some of these initial 'suspects' included the ergot alkaloids of tall fescue, potential cyanide content of white clover, wide Calcium/Potassium ratios in pasture, fungal mycotoxins and the presence of certain poisonous plants. Certain consultants also indicated that no one should purchase or feed any Kentucky hay in 2001. However, these statements were not based on any hard information, just one person's opinion. But great damage was done to the confidence in Kentucky grown hay.

Alfalfa, The Queen Of Forage Crops — Reflections After Sixty Years Experience With The Crop, Warren C. Thompson

Kentucky Alfalfa and Stored Forage Conference

Yes, it is true I have been involved with alfalfa for 60 years and then some. Fact is I was fortunate enough to pick the World's best forage on which to base much of my career about the same time I fell in love with and married the best lady I ever knew. Betty has stuck with me through these crazy wonderful years. She was largely responsible for matters at home and raising the family. She managed our family and home while I was on the move trying to encourage maybe even coerce farmers in Kentucky and then over the …

Alfalfa For Summer Grazing, Jason Sandefur

Kentucky Alfalfa and Stored Forage Conference

Jason manages the Berle Clay Farm in Paris, Kentucky. The farm has been in the Clay family since the 1770's. The Homestead was built in 1778.

The farming operation consist of approximately 680 acres of orchardgrass-clover, 300 acres of orchardgrass-alfalfa, 210 acres of tall fescue-clover, 100 acres of crops, 13 acres of tobacco and 70 acres in roads, buildings, etc.

Advances In Developing Better Alfalfa Varieties, Jim Moutray

Kentucky Alfalfa and Stored Forage Conference

Alfalfa breeders continue to actively pursue the development of varieties that will bring more benefits to farmers. Yield and better persistence are our highest priorities. Other traits under selection can make alfalfa easier and cheaper to grow, better and safer for livestock and more attractive to livestock.

The goal of this paper is to update you on the types of alfalfa research going on in the U.S., time tables on when you may expect to see these new developments and how they may help you in your operation.

Alfalfa Hay Quality: Terms And Definitions, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

At the 22^nd Kentucky Alfalfa Conference we discussed the relationship among Alfalfa - Yield-Quality-Persistence. In our presentation, we indicated that all three components must be considered for best management of alfalfa stands. Over the past week, I have looked through the past twenty-two years of Alfalfa Conference Proceedings. It's interesting, but not surprising that we have focused far more attention on yield than on quality and/or persistence.

Alfalfa yield (quantity) and quality are both important; however, it is easier for producers to recognize problems associated with quantity than quality because quantity can be easily assessed visually. Thus, forage quantity …

A Watershed Analysis Of Threemile Pond: Implications For Water Quality And Land Use Management, Colby Environmental Assessment Team, Colby College, Problems In Environmental Science Course (Biology 493), Colby College

Colby College Watershed Study: Threemile Pond (2003)

The 2003 Colby Environmental Assessment Team chose to study the Threemile Pond watershed. The Threemile Pond watershed is located in Vassalboro, China., Windsor, and Augusta, Maine. Threemile Pond is a popular site for recreation and is home to a wide range of flora and fauna. Like all other lakes in Maine, it is a young lake. However, intensive human activity in the watershed contributes a substantial amount of nutrients and the lake has algal blooms annually in the summer months. The purpose of this study was to assess the impact of land use and development on the water quality of …

Sedimentological And Plant Taphonomic Evaluation Of The Early Middle Devonian Trout Valley Formation, Jonathan Allen

Honors Theses

The Trout Valley Formation of Emsian-Eifelian age, outcropped in Baxter State Park, Maine, consists offluvial and coastal deposits preserving early land plants. Massive, crudely bedded conglomerate represents deposits of proximal braided channels on an alluvial fan complex. Lithic sandstone bodies in channel-form geometries represent deposits of river channels draining the Acadian highlands whereas associated siltstones represent overbank deposits, intertidal flats, and tidal channels. Localized lenticular quartz arenites represent nearshore shelf bar deposits that were storm influenced. The majority of plant assemblages preserved mainly in siltstone lithologies are allochthonous and parautochthonous, with only one autochthonous assemblage identified in the sequence. Plant …

Soils Of Mississippi County, Arkansas, J. M. Mckimmey, B. Dixon, H. D. Scott, C. M. Scarlat

AAES Research Reports and Research Bulletins

Along with air and water, soil contributes essential processes to the natural order of global cycles. With the exception of edibles from the sea, virtually everything we, and most other land-based animals, eat is derived from soil. Soil is a storage medium of essential minerals and nutrients for fulfilling our agricultural and nutritional needs. Humans work the soil to provide the basics of food, clothing, and shelter. We also use the soil as a medium to store and discard our waste. Virtually everything we do is in some way connected to soil

Property Planning Manual For The Swan-Canning Catchment - February 2002, Catherine Nind, Kylie Banfield, Brian Lloyd

Farm Systems and Economics published reports

Perth, its suburbs and adjacent semi rural and rural areas are part of the Swan-Canning catchment. Ona broad scale the Swan and Canning Rivers are part of a large drainage system that collects and drains water from across the catchment via a myriad of small channels, creeks, brooks and drains which, working together, concentrates the flow into a single water body, the Swan-Canning Estuary. This drainage system collects water both from the surface of the land and also from water, which seeps beneath the surface and moves underground.

The water may contain a considerable variety of potential pollutants, such as …

Communicator-In-Chief: Presidential Use Of Television Past, Present, And Future, Jenna Wasson

Honors Theses

This thesis seeks to determine how television has changed as a communication medium for presidents over the past half century. An evaluation of the evolving ways presidents use television to communicate with and to build support from the American people has been conducted. Presidential communication strategies have been identified by drawing primarily from primary sources written by presidents and White House staff. Television technology and the television audience have changed over the years. Presidents have taken a more pro-active, aggressive role in their efforts to harness television for their own purposes. Why have these changes occurred? What impact have these …

Package Options For Alfalfa, Michael Collins

Kentucky Alfalfa and Stored Forage Conference

Most of the hay crop in Kentucky is harvested as dry hay and stored in round bales of various sizes for feeding on the farm. Most of the round-baled hay in Kentucky is used on-farm in feeding beef and dairy cattle. When alfalfa hay in round bales is left outside without protection from the weather, large losses in DM yield and in forage quality usually result. We routinely measure DM losses in the range of 20- 35% for a normal length hay storage season. Our research has shown that several economical storage options exist for protecting this hay from weathering. …

Marketing Kentucky Hay, Billy Ray Smith

Kentucky Alfalfa and Stored Forage Conference

The production of hay and pasture crops is essential to a profitable future for Kentucky agriculture. The Commonwealth ranked seventh in the nation in hay production in the year 2000 with 6.2 million tons. These forages provide the bulk of the feed supply for our livestock industry. In addition, a significant portion of our hay crop is marketed, both to in-state and out-of-state buyers.

Innovative Loading And Stacking Systems For Custom Hay Sales, Tom Keene

Kentucky Alfalfa and Stored Forage Conference

As the face of agriculture continues to change, so does the hay industry. What was standard operating procedure twenty years ago is now no longer economically feasible in the cash hay industry. This is especially true in the loading and stacking end of the business.

The business has changed because new technology along with the dramatic decrease in the availability of "hand labor" has helped to drive the need for new loading and stacking systems for the hay industry. These two phenomenon will continue to drive us toward total mechanization in the hay industry in fact many hay producers are …

Designing A Grazing System For Alfalfa, Ken Johnson

Kentucky Alfalfa and Stored Forage Conference

As we think about grazing alfalfa, we should decide why we are considering alfalfa and where it fits. I want to address some of these issues from my prospective as a grazer with several years experience and as an agriculture employee working with many grazers over the years. Alfalfa is the most productive, high quality grazing forage we can grow in Kentucky; we need to be using it more.

Grazing Alfalfa At The Western Kentucky University Farm, Byron Sleugh, Raquel Stiles, David K. Stiles, Amanda Canty, Curtis Mitchell

Kentucky Alfalfa and Stored Forage Conference

Alfalfa has been around for centuries. In all this time, it was used in many different ways to provide high quality forage to livestock. In fact, in the area where alfalfa originated, the word actually means "horse power". We have come a long way since then and alfalfa is used for a wide range of animals, from rabbits to rhinos.

In order to maximize the efficiency of utilization of alfalfa, it has become necessary to graze it. Grazing is preferred over harvesting and storage for several reasons: less equipment and thus lower cost, less harvest loss, and greater quality forage …

Managing Alfalfa For Yield-Quality-Persistence, Garry D. Lacefield

Advances In Alfalfa Breeding — What Will The Alfalfa Variety Of The Future Smell, Taste, Look And Act Like?, Jimmy C. Henning

Kentucky Alfalfa and Stored Forage Conference

Alfalfa is the highest quality, highest yielding and arguably the highest value forage crop in Kentucky and in the US. It is useful as hay, haylage or pasture for a variety of species of livestock. It is well adapted to Kentucky and is an important part of the forage/livestock system.

Alfalfa breeders are actively working to develop varieties that will meet and exceed farmer expectations for yield and persistence. In addition, other traits are sought after to make the variety meet a special need or to have better marketability or attraction to the customer.

So what will the alfalfa of …

Organic Wheat : A Production Guide, Steven Mccoy

Bulletins 4000 -

Many people believe that organic agriculture systems can only work in high rainfall regions. However, some of Australia’s most successful organic farmers are the experienced organic wheatbelt growers who produce cereal, pulse and oilseed crops in different regions and soil types across the country.

Wheat is the major organic cereal crop grown in Australia - predominantly noodle and breadmaking wheats for export markets.

Farming systems developed by modern organic wheat growers can differ significantly in concept, strategies and techniques from those used by conventional growers. Successful conversion to organic requires careful planning and integration of the whole farming system over …
