Cost And Return Of Alfalfa Hay Production, Kenneth H. Burdine Feb 2009

Cost And Return Of Alfalfa Hay Production, Kenneth H. Burdine

Kentucky Alfalfa and Stored Forage Conference

The last few years have been nothing short of a roller coaster ride for Kentucky agriculture. Kentucky is coming off back-to-back drought years, which have challenged both livestock and crop producers. At the same time, farmers are dealing with decreasing output prices and rising input prices. This is a recipe for pure frustration and alfalfa producers have not been isolated from these challenges.

Keys To Success With Alfalfa Balage, Dennis W. Hancock Feb 2009

Keys To Success With Alfalfa Balage, Dennis W. Hancock

Kentucky Alfalfa and Stored Forage Conference

Baled silage (or Balage) has many advantages over conventional hay production. Losses during the curing, baling, storage, and feeding phases are each dramatically lower when the forage is conserved as Balage rather than hay. Of course, this comes at an expense. The cost of the wrapper (generally $14,000 – 21,000), plastic wrap (usually $4-6 per ton of DM), and added labor can make this system quite costly. Furthermore, there is an environmental cost for disposal of the plastic. However, Balage enables the alfalfa producer to quickly harvest a crop with more independence from unfavorable weather and to create a more …


Alfalfa As A Grazing Crop, Bill Payne Feb 2009

Alfalfa As A Grazing Crop, Bill Payne

Kentucky Alfalfa and Stored Forage Conference

Planning a “Forage Sequence” implies that a stockman provides nutritious and palatable forage crops for grazing for as many days of the year possible. Cool season perennial grasses and legumes give Kentucky forage growers an competitive advantage over those in many other states. That advantage declines during the heat of our summers, however. Providing a solution to our “Summer Slump” is a challenge to stockmen throughout the South. This “Summer Slump” is the result of low yield of cool season forages during the heat and drier conditions of July, August and September. Another factor hindering livestock gains is the fescue …


Alfalfa Hay For Horses: Myths Vs. Reality, Laurie Lawrence Feb 2009

Alfalfa Hay For Horses: Myths Vs. Reality, Laurie Lawrence

Kentucky Alfalfa and Stored Forage Conference

How Much Hay Does A Horse Need?

A horse owner once described their Quarter Horse gelding as “a hole in the stall that I throw hay into”! This description is certainly accurate… a 1200 lb gelding used for light recreational riding will consume about 700 lbs of hay per month during the winter in Kentucky. If the horse is kept in a place with minimal pasture, yearly hay consumption will be about 4 tons. Restricting hay intake can lead to digestive disturbances and behavior problems, so it is recommended that most horses be allowed access to 1.5 – 2.0 lbs …


Alfalfa Seed Price And Seeding Rate: Impact Of Production Cost, S. Ray Smith Feb 2009

Alfalfa Seed Price And Seeding Rate: Impact Of Production Cost, S. Ray Smith

Kentucky Alfalfa and Stored Forage Conference

I am often asked the question about what is the ideal alfalfa seeding rate, especially with the price of seed for most improved varieties over $4.00 per pound. Before giving the ideal seeding rate or recommended range of seeding rates, let me overview alfalfa seed size, seedling survival, and plant survival. Alfalfa has about 200,000 seeds/lb. If one pound was evenly spread over one acre (43,560 ft2), there would be about five seeds per square foot. Therefore if you take the seeding rate you are using and multiply by five, you will come pretty close to knowing how …


Rfv Vs. Rfq -- Which Is Better?, Tom Keene, Peter Jeranyama, Alvaro D. Garcia Feb 2009

Rfv Vs. Rfq -- Which Is Better?, Tom Keene, Peter Jeranyama, Alvaro D. Garcia

Kentucky Alfalfa and Stored Forage Conference

Determining the value of hay is often times a trying adventure but the rewards can be significant. It begs the question though, what do those numbers really tell me? Do they provide me pertinent information? There are so many numbers…which ones do I need to be concerned with? All of the numbers and information on the results sheets are important. However, certain numbers have greater bearing on some classes of livestock than others. As research continues to give us new parameters regarding, herd health, pounds of gain, pounds of milk, maintenance, etc. the importance of these will also likely change …


Art And Science Of Haymaking, Garry D. Lacefield Feb 2009

Art And Science Of Haymaking, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

In 2007, Kentucky was chosen as one of three states to participate in the making of a movie on Quality Haymaking. Case IH Agriculture in an effort to better serve their customer base and the forage industry invested resources to produce, edit and distribute a DVD on Quality Haymaking. A national project coordinator was hired who in turn contracted with a film company. When we were contacted and learned it was not going to be a commercial for any one brand or product, we agreed to participate.

Overland Flow And Rainfall Simulation Studies On Ornamental Vegetation, Compost, And Jute Netting, Brent G. Hallock, Candace Kimmelshue, Steve Rein, Michael Curto, Misty Scharff Feb 2009

Overland Flow And Rainfall Simulation Studies On Ornamental Vegetation, Compost, And Jute Netting, Brent G. Hallock, Candace Kimmelshue, Steve Rein, Michael Curto, Misty Scharff

Earth and Soil Sciences

The literature is replete with studies quantifying erosion control effectiveness from raindrop impact on various vegetation types and erosion control products. However, there is little published overland flow research documenting the effectiveness of ornamental vegetation and erosion control products in filtering sediment and nutrients from stormwater runoff. The California Department of Transportation and the Office of Water Programs, California State University, Sacramento, has conducted two studies at the Erosion Control Research Facility at Cal Poly State University, San Luis Obispo addressing the use of ornamental vegetation as an erosion control treatment. The first study addressed how well ornamental vegetation, jute …


Tree Canopy Types Constrain Plant Distributions In Ponderosa Pine- Gambel Oak Forests, Northern Arizona, Scott R. Abella Feb 2009

Tree Canopy Types Constrain Plant Distributions In Ponderosa Pine- Gambel Oak Forests, Northern Arizona, Scott R. Abella

Public Policy and Leadership Faculty Research

Trees in many forests affect the soils and plants below their canopies. In current high-density southwestern ponderosa pine (Pinus ponderosa) forests, managers have opportunities to enhance multiple ecosystem values by manipulating tree density, distribution, and canopy cover through tree thinning. I performed a study in northern Arizona ponderosa pine-Gambel oak (Quercus gambelii) forests to measure the influences of tree canopy types on understory plant communities and soil properties. On ten 2.5-acre (1-ha) sites, I sampled five 43-ft2 (4-m2) plots below each of the following five canopy types: openings; single ponderosa pine; and Gambel oak single stems, dispersed clumps, and thickets. …


Soil Ph In Northern And Southern Areas Of The Wa Wheatbelt, Chris Gazey, Joel Andrew Jan 2009

Soil Ph In Northern And Southern Areas Of The Wa Wheatbelt, Chris Gazey, Joel Andrew

Bulletins 4000 -

More than 80% of the topsoils sampled fall below the critical surface pHCaCl2 of 5.5 in the northern and southern wheatbelt study areas, with more in the south than the north. These results confirm soil acidity is a serious concern throughout the WA wheatbelt when considered in conjunction with the more intensive analysis of current soil pH throughout the Avon River Basin (2005–2008).

With low topsoil pH, it is likely that subsurface acidity is also a problem. For soil acidity to be managed, subsurface pH also needs to be known. In the Avon River Basin study, about half of the …


Survey Of Western Australian Agricultural Lime Sources, Chris Gazey, Dave Gartner Jan 2009

Survey Of Western Australian Agricultural Lime Sources, Chris Gazey, Dave Gartner

Bulletins 4000 -

As a service to WA wheatbelt farmers, to assist with cost effective management of soil acidity, a survey of agricultural lime availability and quality was conducted by the Department of Agriculture and Food, Western Australia.

The quality of agricultural lime surveyed varied widely between pits. High quality lime is available from limes and, limestone and dolomite sources. Twice as much of the lowest neutralising value lime surveyed would need to be applied compared to the highest to achieve the same increase in soil pH. Limes also varied in the distribution of particle sizes. Selecting limes with a high proportion of …

Integration Of An Extended Octagonal Ring Transducer And Soil Coulterometer For Identifying Soil Compaction, Santosh K. Pitla, Larry G. Wells, Scott A. Shearer Jan 2009

Integration Of An Extended Octagonal Ring Transducer And Soil Coulterometer For Identifying Soil Compaction, Santosh K. Pitla, Larry G. Wells, Scott A. Shearer

Biosystems and Agricultural Engineering Faculty Publications

The soil coulterometer is an "on-the-go" electro-mechanical system which collects impedance force data at multiple depths using an oscillating coulter. During the initial testing (summer 2006), only vertical soil impedance force data was collected using a pressure sensor. To improve the performance of the coulterometer, an extended octagonal ring transducer was integrated into the system to collect both the horizontal and vertical impedance forces given by the soil. In the summer of 2007, data was collected using the revised sensor from a typical central Kentucky field setting in a 0.8-ha (2-acre) plot. Four passes were made with the coulterometer. Seventy …
