Bioaccumulation of trace metals in plant tissues can present a health risk to wildlife, and potentially to humans. The Passamaquoddy Tribe in Maine was concerned about health risks of cadmium (Cd) because of a health advisory for moose liver and kidney consumption due to high Cd levels. In addition to Cd, this study evaluated concentrations of aluminum (Al), calcium (Ca), copper (Cu), iron (Fe), potassium (K), magnesium (Mg), manganese (Mn), nickel (Ni), phosphorus (P), lead (Pb), and zinc (Zn) in four common terrestrial moose-browse species, associated forest soils, and two species of aquatic vegetation on Passamaquoddy tribal land in eastern …

Feed costs represent the major cost in most livestock production systems. A recently completed analysis of 225 Standardized Performance Analysis (SPA) Beef Cow Records on herds in Illinois and Iowa showed that feed cost was the overriding factor determining profitability, explaining over 57 percent of the herd-to-herd variation.
Dollars & Cents Of Intensive Grazing, Kenneth H. Burdine
Dollars & Cents Of Intensive Grazing, Kenneth H. Burdine
Kentucky Grazing Conference
A rotational grazing system can generally be defined as the use of several pastures with one being grazed while the others are rested. On the contrary, conventional or continuous grazing systems allow livestock access to the entire pasture area and let them decide where, what, and how long to graze. In most cases, Kentucky pastures employing continuous grazing systems are too large for efficient management and forage utilization. In such instances, cattle overgraze more palatable forages and areas close to shade and water, while other sections of the pasture are underutilized. This leads to lower animal output per acre than …

Uk Horse Pasture Evaluation Program, Tom Keene, S. Ray Smith
Kentucky Grazing Conference
The University of Kentucky is developing stronger ties with the state’s horse industry in the areas of research, extension and teaching. Many horse farms in the bluegrass region are interested in UK’s assistance with pasture evaluation. During the fall of 2005 a team from the UK Forage Extension Program (Ray Smith, Tom Keene, Jesse Morrison, Gabriel Roberts) conducted a pilot project to evaluate horse pastures on 14 central KY farms. One of the focuses of the pilot was the evaluation of pastures for percent tall fescue and the potential of fescue stands to cause fescue toxicity in pregnant broodmares. We …
Managing Pasture Growth And Quality With Grazing, S. Ray Smith
Managing Pasture Growth And Quality With Grazing, S. Ray Smith
Kentucky Grazing Conference
One of the keys to profitable livestock production is to minimize the costs of producing a marketable animal or animal product. Feed costs are commonly 70-80 percent of the cost of growing or maintaining an animal. Pastures provide feed at a cost of .01-.02 cents/lb of TDN while hay costs .04-.06 cents/lb TDN. Improved pasture management offers the single greatest opportunity to lower production costs, assuming that animal genetics, health, marketing procedures, and other areas of management have been addressed. A primary goal of livestock producers should be to utilize grazed forage for as many months of the year as …
Everyday Cattle Graze Is Money Saved, Garry D. Lacefield
Everyday Cattle Graze Is Money Saved, Garry D. Lacefield
Kentucky Grazing Conference
During one of my first visits to New Zealand over twenty years ago, I had the opportunity to visit many different dairy, beef, sheep and deer farms. While visiting a dairy farm, I remember the farmer telling me about his grazing program and their goal to “optimize grazing and minimize stored feed.” I remember him saying, “everyday grazed is money saved”. I admit, the reality of that statement didn’t truly sink in that day; but over the years, the truth of what he said has not only “sunk in” but has been reinforced by visits to other farms literally around …
Bermudagrass In Kentucky, David C. Ditsch
Bermudagrass In Kentucky, David C. Ditsch
Kentucky Grazing Conference
Interest in bermudagrass [Cynodon dactylon (L.) Pers] is increasing in Kentucky as livestock producers continue their search for warm-season perennial forages capable of filling in the mid-summer growth slump we commonly experience with our traditional cool-season grasses. This is partially due to the recent availability of seeded bermudagrass varieties with improved winter hardiness thereby reducing establishment cost and increasing the odds of success.
Grazing Corn, Chad Lee
Grazing Corn, Chad Lee
Kentucky Grazing Conference
Grazing is the cheapest form of feed for cattle. While perennial grasses and alfalfa are reliable components to a grazing system, another component could be corn.
Grazing corn is an option for a couple of situations: 1) as a bridge crop when pasture renovation is needed, and 2) as an insurance crop in an overall grazing system.

Sequential Extraction Of Copper And Zinc From Two Californian Soils, Katharine Carr, Christopher Appel, Craig Stubler, Shana Mccarthy
Sequential Extraction Of Copper And Zinc From Two Californian Soils, Katharine Carr, Christopher Appel, Craig Stubler, Shana Mccarthy
Earth and Soil Sciences
In order to understand how to remediate soils contaminated with heavy metals, it is important to first understand their sorption mechanisms. The objective of this study was to evaluate the bioavailability of elevated levels of soil copper (Cu) and zinc (Zn) via sequential extraction. Elevated levels of Cu and Zn were added separately and concurrently to a Mollisol and an Entisol from the central coast of California. The exchangeable amount of Cu and Zn was then extracted from the sorbed amount via 0.1 M NaNO3. The residual fraction was then extracted with 0.1 M sodium citrate (NaC6 …

Earth and Soil Sciences
The presence of large quantities of Chromium metal in soil and plants is of major concern due to its toxicity to humans. Total (USEPA 3050a) and bioavailable (USEPA 1311) levels of chromium were measured along a serpentinic Central Coast toposequence. Soil from the surface and subsurface, as well as the above ground plants of the toposequence were determined and compared to several soil chemical and physical properties using a least squares regression. The binding environments and oxidation states were found through XANES and EXAFS x-ray spectroscopies. The total and bioavailable chromium concentrations of the soil averaged 1457.1 and 1.6 mg …
Quaternary Deposits Near The San Emigdio Mountains, California: Evidence For A Paleolandscape?, Paul G. Lavelle
Quaternary Deposits Near The San Emigdio Mountains, California: Evidence For A Paleolandscape?, Paul G. Lavelle
Earth and Soil Sciences
Discontinuous low-relief surfaces are scattered throughout relatively high topography within the San Emigdio Mountains, California. These surfaces are considered anomalous, as they are preserved in a dissected, mountainous region that is affected by ongoing orogeny. Previous research has suggested that the low-relief surfaces may represent a once-contiguous alluvial surface. This project utilizes field mapping and sedimentological analysis to determine if the surfaces represent a paleo landscape. What is apparent from field work is the presence of two morphologically distinct lithologic units that most likely represent surficial geologic components of the same relict landscape.

Alstroemeria, Aileen Reid
Bulletins 4000 -
About 60 species of Alstroemeria grow wild in South America, in habitats ranging from the snowline of the Andes and high mountain plateaus down through the highland forests to the coastal deserts.
A member of the lily family, Alstroemeria grows from a rhizome that also develops tuberous storage outgrowths and fleshy roots. The aerial shoots can be either vegetative or reproductive. Normally shoots that have unfolded more than 30 leaves will not flower and remain vegetative.
The leaves of Alstroemeria are unusual in that they rotate through 180 degrees as they unfold, so that the upper surface becomes the lower …

Current Status And 25 Year Trends For Soil Acidity, Fertility And Salinity In The Coastal Catchments Of The Peel-Harvey, Robert Summers, David Weaver
All other publications
The current status and trends of soil analyses in the coastal catchment of the Peel Harvey estuary were developed from historical soil data (1982 to 1991) combined with a renewed sampling to greater depth (1 m). This report encompasses the data collected from the first year of the project. Soil phosphorus content was found to be high but has dropped slightly since 1991. Soil pH is very low and is likely to be limiting production but have risen slightly since 1991. Soil potassium content is generally so low that it may be limiting production especially to the west of the …

Semi-leafless field pea like Kaspa have lifted the benchmark set by the previous conventional varieties such as Parafield and Dunwa. Semi-leafless field pea have the same traits as conventional field pea: adaptation to a range of soil types; wide selection of weed control options (including crop topping); nitrogen input; disease break; and reduction in root lesion nematodes. Semi-leafless pea is easier to harvest and is less prone to pod shatter.

Why Dairy Farmers Need And Want High Quality Alfalfa Hay: Quality Of Hay = Performance And Profitability, Donna M. Amaral-Phillips
Why Dairy Farmers Need And Want High Quality Alfalfa Hay: Quality Of Hay = Performance And Profitability, Donna M. Amaral-Phillips
Kentucky Alfalfa and Stored Forage Conference
Why do dairy farmers want high quality forages, including alfalfa hay, to feed to their milking herds? Feeding high-quality forages results in greater feed intake and as a result, dairy cows produce more milk, and they often times can produce this milk more economically. With advancing stage of plant maturity, fiber digestibility and protein content of the alfalfa plant decreases while the amount of fiber increases. Consequently, less energy is available to the cow when it consumes more mature alfalfa. Energy is the nutrient that most often limits performance in dairy or beef cattle - not protein. The take home …
Alfalfa Hay For Horses, Robert Coleman
Alfalfa Hay For Horses, Robert Coleman
Kentucky Alfalfa and Stored Forage Conference
When horse owners consider hay for their animals a number of criteria are generally considered. Of major importance is the hay must be free of mold and dust, it needs to contain nutrients needed by the horse and it must be palatable. If these criteria are met, the type of hay should not matter. However, that is not the case with many horse owners. When discussing hay, many owners first consider the type of hay. Can it be alfalfa or should it be a grass or how about a mix of grass and a legume. If a group of horse …

Interpreting Forage Quality Test Reports, Donna M. Amaral-Phillips
Kentucky Alfalfa and Stored Forage Conference
Forages are the foundation for building diets for beef and dairy cattle, horses, sheep and goats. The quality of these forages directly impacts forage intake, animal performance, and, ultimately, the profitability to their owners. As the quality of forages decline, consumption of that forage decreases and the amount of grain or byproducts which must be fed increases. The cost for a unit of performance increases and/or the animal can not perform (i.e. milk or gain) to the optimum level thus lowering profitability to the animal owner. These relationships are especially true with young and high performance ruminants, such as high …

Moisture Management In Hay Making And Storage, Tom Keene, Doug Overhults
Kentucky Alfalfa and Stored Forage Conference
Making hay in central Kentucky can be one of the most trying on farm endeavors a producer can undertake. Our plentiful moisture, rolling topography, and climate make Kentucky ideal for producing high quality forage for either grazing or hay making. However, that same moisture, either in the form of rain or high humidity, can sometimes make it devilishly hard to make hay here in Kentucky.
