The Economics Of Integrating Crop Land To Mig Grazing, Edward N. Ballard Nov 2003

The Economics Of Integrating Crop Land To Mig Grazing, Edward N. Ballard

Kentucky Grazing Conference

Illinois soils vary in their properties and producing capacities. Large areas of the state have soils that are among the most productive in the world. Other areas have soils that, because they are too steep or droughty or have some other undesirable features, are not the most productive for corn and soybeans.

However, over the past 30 years there has been a trend to place more acres in Illinois in corn and soybeans and less acres in small grains, legumes and pasture crops. Government incentive programs have encouraged more acres to be place into corn and soybean production.


Environmental Benefits With Improved Grazing, David Stipes Nov 2003

Environmental Benefits With Improved Grazing, David Stipes

Kentucky Grazing Conference

The public is becoming better educated about the environment and will continually question activities that are perceived as being harmful to soil, water, air, plants, people, animals and other concerns. Livestock producers who implement well-planned grazing management systems have an excellent opportunity to compliment both production and natural resource conservation considerations. All segments of the population involved in production agriculture will be held accountable for environmental impacts that result from their operation. A proactive approach is needed by livestock and other agricultural producers to sustain the protection of the environment that is in harmony with a healthy ecosystem. All those …


Grazing Systems For Beef Cattle, John Johns Nov 2003

Grazing Systems For Beef Cattle, John Johns

Kentucky Grazing Conference

Beef cattle represent the most important grazing livestock enterprise to Kentucky producers. As of January 1, 2003 there were 1,120,000 producing beef brood cows on 39,000 farms in the state. In addition, more than 600,000 yearling cattle are also produced. The number of total beef animals is increasing as producers put more economic reliance on beef and forage programs. In many cases, beef cattle represent the only practical method of converting high quality forage to income for producers.


Grazing Systems For Dairy, Donna M. Amaral-Phillips Nov 2003

Grazing Systems For Dairy, Donna M. Amaral-Phillips

Kentucky Grazing Conference

Forages which are grazed can provide anywhere from 25 to 100% of the forage consumed by growing dairy heifers, dry cows or the milking herd. In this paper, I would like to specifically deal with devising a grazing program for a dairy lactating or milking herd. Lactating dairy cows are a “high performance animal” and, as such, any decreases in the availability or quality of forage can quickly decrease milk production. Thus, the goal when designing a grazing system is to provide adequate quantities of high-quality, vegetative forage to prevent decreases in performance. These decreases in performance occur in all …


Opportunities For Warm Season Grasses, Ken Johnson Nov 2003

Opportunities For Warm Season Grasses, Ken Johnson

Kentucky Grazing Conference

Today I would like to do two things, first talk a little about warm season grasses, where they come from, and where they might fit in your grazing program; and second, talk about the four major native grass species and two introduced species.

Native warm season perennial grasses were an important part of the native forage species of Kentucky, supplying food and cover for deer, buffalo, and other wildlife when settlers arrived into Kentucky. With settlers plowing, overgrazing, and the introduction of other forages, Native Warm Season Grasses (NWSGs) were on the brink of extinction. These grasses included switchgrass, eastern …


Optimize Grazing--Minimize Stored Feed, Garry D. Lacefield Nov 2003

Optimize Grazing--Minimize Stored Feed, Garry D. Lacefield

Kentucky Grazing Conference

The title “Optimize Grazing – Minimize Stored Feed” appears to be a bit redundant at first glance. Indeed if we optimize grazing, we will certainly minimize the amount of stored feed required to winter our animals. Putting both concepts together can serve as a reminder of the tremendous benefit of both.

Grazing represents the cheapest source of nutrients for our beef industry. Several studies have shown that the best predictor of profitability in the beef industry is cost of stored feed. In Kentucky, specifically, that means cost/amount of hay required to winter on beef animals.

The Development Of Relationships Between Constituent Concentrations And Generic Hydrological Variables, Carmen T. Agouridis, Dwayne R. Edwards Mar 2003

The Development Of Relationships Between Constituent Concentrations And Generic Hydrological Variables, Carmen T. Agouridis, Dwayne R. Edwards

Biosystems and Agricultural Engineering Faculty Publications

The collection and analysis of samples from storm events constitutes a large portion of the effort associated with water quality research. Estimating concentrations or loads from these events is often difficult. The equipment necessary to analyze the samples and the required laboratory resources are typically significant expenses incurred by the researcher. One potential method to reduce these costs is through the development of generic relationships between concentrations and easily measured variables such as dimensionless flow rate or time. The benefits recognized from such an effort include a reduction in the number of required samples, resulting in a reduction in cost. …


Alfalfa Disease Management, Paul Vincelli Feb 2003

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 Feb 2003

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 Feb 2003

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 Feb 2003

Forage Testing & Marketing Program, Allen Johnson

Kentucky Alfalfa and Stored Forage Conference

Two thousand and three marks the 141th 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 Feb 2003

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 Feb 2003

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 Feb 2003

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 Feb 2003

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 …

Advances In Developing Better Alfalfa Varieties, Jim Moutray Feb 2003

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 Feb 2003

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

Kentucky Alfalfa and Stored Forage Conference

At the 22nd 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 …

Value Of Nutrients In Poultry Litter When Applied In The Fall, Monroe Rasnake, George Kelley Jan 2003

Value Of Nutrients In Poultry Litter When Applied In The Fall, Monroe Rasnake, George Kelley

Soil Science News and Views

The value of nutrients in poultry litter depends not only on how much nitrogen (N), phosphorus (P) and potassium (K) it contains, but also on how it is handled and applied. The following table compares the value of 19 poultry litter samples from Hopkins County analyzed for N, P & K and the litter then spread in the fall. The samples include pullet, breeder and broiler manures, with storage times up to one year. Nutrient values were based on a comparison with urea (46-0-0) at $199/ton, triple super phosphate (0-46-0) at $215/ton and muriate of potash (0-0-60) at $165/ton.

Precision Farming In Central Kentucky: Evaluating Public And Private Sector Influence On The Adoption Decision, Rod Grusy Jan 2003

Precision Farming In Central Kentucky: Evaluating Public And Private Sector Influence On The Adoption Decision, Rod Grusy

Soil Science News and Views

The Cooperative Extension Service is challenged to assess the needs of customers who are unable or unwilling to try new production techniques with the potential to increase profitability. Precision Farming (PF) is a production technique that has the goal of maximizing economic potential by using technology that recognizes variability within fields. Ample research from the last decade shows that precision technologies hold promise for enhanced agricultural profitability. A study conducted in three Central Kentucky counties in 2001 shows that farmers obtain information for decision-making related to PF technologies from their local fertilizer dealer and the Cooperative Extension Service but are …
