Groundwater Test Pumping In The Tambellup Townsite, Louise Hopgood
Groundwater Test Pumping In The Tambellup Townsite, Louise Hopgood
Resource management technical reports
Previous studies have concluded that the township of Tambellup is underlain by a perched aquifer. Test pumping and groundwater modelling indicated that groundwater pumping may be an effective way of protecting townsite infrastructure by lowering the water table beneath the town. This report presents results of the test pumping and provides likely bore yields, prediction of pumping influence and likely optimum production bore spacing.
Efficient Grazing Systems: Putting Pieces Together, Charles T. Dougherty
Efficient Grazing Systems: Putting Pieces Together, Charles T. Dougherty
Kentucky Grazing Conference
Pros and cons of grazing systems are well-known to this audience. Efficient grazing systems, however, are a different story. What is an efficient grazing system? I think we could argue that topic until the cows come home and I do not believe we could come to any agreement. I am going to approach the subject of efficiency from several angles but you will probably see them differently. Economic efficiencies will not be covered.
Kentucky Goat Friendly Pasture Concepts, Terry Hutchens
Kentucky Goat Friendly Pasture Concepts, Terry Hutchens
Kentucky Grazing Conference
Goats are accomplished grazers of grass and browse plants. In addition, they can be managed within a grazing system both intensively or extensively as long as quality forage is made available. Goats are facultative browsers, they prefer to feed at eye level and upward and then feed on forage from the top of the plant down. Goats prefer to move freely from plant to plant-removing foliage from select portions of plants. Foliage meals are dictated by quality factors that insure adequate protein and energy levels. Each stem or leaf is clipped with precision leaving the forage residue standing equal in …
Effective Use Of Pastures For Horses, Robert Coleman
Effective Use Of Pastures For Horses, Robert Coleman
Kentucky Grazing Conference
Pastures can serve two very necessary functions for the care and maintenance of horses. Not only do these areas of grasses and legumes provide a place for the horse to exercise, they can provide a significant portion of the horse’s nutrient requirement. Horses evolved as a grazing animal, so it is reasonable that many classes of horse can be adequately maintained on well-managed pastures.
The Economics Of Integrating Crop Land To Mig Grazing, Edward N. Ballard
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
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
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
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
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
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.

Successful Field Pea Harvesting, Glen Riethmuller, Ian Pritchard
Successful Field Pea Harvesting, Glen Riethmuller, Ian Pritchard
Bulletins 4000 -
Many thousands of hectares of field peas are harvested trouble free each year. Growers experience together with recent machinery innovations and modifications have solved the majority of harvesting difficulties. Optimum harvesting conditions are in a crop of uniform density on a level soil surface with the machine either working into or across the direction that the crop has been laid by the wind.
To make harvest easier the receival standard for moisture in pulses has been lifted to 14 per cent, which allows harvest to begin sooner when the crop is the range of 14 to 15 per cent moisture. …

Rapid Catchment Appraisal aims to document salinity risk and management options by addressing all threats to the natural resource base, rather than isolating salinity as a separate issue.
Analysis Of The Effects Of Hypogeal And Epigeal Emergence On Seedling Competition In Legumes, Keith E. King
Analysis Of The Effects Of Hypogeal And Epigeal Emergence On Seedling Competition In Legumes, Keith E. King
McCabe Thesis Collection
Seedling emergence is either hypogeal or epigeal. In hypogeal emergence the cotyledons remain below the soil surface during seedling development, while in epigeal emergence the cotyledons extend above the soil surface due to elongation of the hypocotyl. Here we examine the effect of seed size, and emergence type, on seedling growth. Six legumes with variation in seed size and either epigeal or hypogeal emergence were grown under dark and light conditions. A competition study was also conducted where a hypogeal and epigeal legume were grown in combination with wheat and ryegrass. Legumes expressing epigeal emergence were cowpea (Vigna unguiculata), mung …
Assessing Storage Reliability Of Farm Dams, D Farmer, N Coles
Assessing Storage Reliability Of Farm Dams, D Farmer, N Coles
Resource management technical reports
This report provides information on a method to estimate the volume of water in a farm dam and to determine how long this water will last. During periods of low rainfall, dams with farmland catchments receive limited run-off. Alternative water sources or management strategies need to be considered before the water runs out. The methods provided in this report are intended to provide to the landholder an indication of water supply over short periods only (i.e. in the order of 4-20 weeks).

Alfalfa Disease Management, Paul Vincelli
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
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 …
Alfalfa Haylage And Silage, Michael Collins
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 …

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.

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

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.
