Post-Tillage Dynamics Of Soil Structural And Hydraulic Properties Induced By Capillary Forces And External Loading, Teamrat Afewerki Ghezzehei

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Tillage modifies the soil structure to create conditions favorable for plant growth. However, the resulting loose structure is susceptible to collapse by internal capillary forces and external compactive stresses with concurrent changes in soil hydraulic properties. Presently, limited understanding of these complex processes often leads to consideration of the soil plow-layer as a static porous medium. The objective of this dissertation was to develop physically based modeling of soil structural dynamics at the pore scale, based on soil mechanical and rheological properties. The basic geometrical framework of the models was based on regular packing of monosized spherical aggregates forming unit-cells. …

Arkansas Water Resources Center Technical Reports

Contamination of ground water has been a major concern in recent years of local, state and federal agencies involved with the management, quality, and quantity of water and their relationships with human health. The Springfield Plateau aquifer, which lies beneath the study area in northwest Arkansas, has been shown to have higher nitrate-N (NO3-N) concentrations than the national median. The dominant landuse (LULC) of this area is agriculture (primarily pasture/cattle and woodlands) and an encroaching urbanization. The major sources of nitrogen in the study area are poultry/cattle wastes, inorganic fertilizers (Peterson et. al., 1998) and septic filter fields. Many of …

Addressing Uncertainty In Tmdls: Short Course At Arkansas Water Resources Center 2001 Annual Conference, Marty Matlock, Matthew Murawski

Arkansas Water Resources Center Technical Reports

Management of a critical natural resource like water requires information on the status of that resource. The US Environmental Protection Agency (EPA) reported in the 1998 National Water Quality Inventory that more than 291,000 miles of assessed rivers and streams and 5 million acres of lakes do not meet State water quality standards. This inventory represents a compilation of State assessments of 840,000 miles of rivers and 17.4 million acres of lakes; a 22 percent increase in river miles and 4 percent increase in lake acres over their 1996 reports. Siltation, bacteria, nutrients and metals were the leading pollutants of …

Esperance Downs Research Station : Rehabilitation Report, Harvey Jones

Resource management technical reports

Esperance Downs Research Station (EDRS) was established in 1949 as an experimental farm. Knowledge from trials on the station has been instrumental in development of agriculture throughout the Esperance region. However, land degradation and in particular secondary salinity became widespread by the 1980s. With potential for similar problems to develop in the region, the EDRS rehabilitation program began in 1990/91. This report details the objectives of this project along with implementation procedures and an assessment of its achievements.

The stated aim of the rehabilitation was 'To research and demonstrate economic methods of obtaining production from land affected by salinity, waterlogging …

Calibration And Use Of A Combination Atmometer To Estimate Evapotranspiration And Monitor Soil Moisture Storage On Farmland Catchments In Western Australia, K J. Bligh

Resource management technical reports

The readily-operated combination method of estimating evapotranspiration was applied using simple atmometers, calibrated against absolute evapotranspiration. While 76.6 per cent of the variance of estimates was accounted for by the regression in the first season under wheat, no significant results were achieved in a further four seasons. Combined data for two seasons under legume pastures enabled 30.1 per cent of the variance of estimates to be accounted for.

Over the years we have all learned of the great potential alfalfa has as a forage crop in Kentucky. We have seen it used as hay, haylage and even pasture. Many aspects of our agri-business community have alfalfa as an important part of their business.

Alfalfa For Beef Cattle, W. Roy Burris

Kentucky Alfalfa and Stored Forage Conference

Alfalfa is sometimes said to be "too good" for beef cattle. Although it's nutritional value may sometimes exceed beef cows' needs, to dismiss it's potential for beef cattle would be a mistake. Alfalfa can be useful as a harvested feed or as a grazing crop.

Alfalfa For Dairy Cattle, Donna M. Amaral-Phillips

Kentucky Alfalfa and Stored Forage Conference

Alfalfa is known as the queen of the forage crops and for good reasons. Alfalfa is an excellent forage for dairy cattle because it provides nutrients needed by dairy cows in a package which is highly digestible and cost effective. Alfalfa can be grazed directly by cattle or harvested as hay, haylage, or batage. Dairy farmers will purchase locally-grown hay if it is high quality (RFV greater than 150). When marketing cash hay one needs to understand that the quality of alfalfa greatly impacts milk production and economics of a dairy operation. This impact is felt even when as little …

Alfalfa Hay For Horses, Laurie Lawrence

Kentucky Alfalfa and Stored Forage Conference

Horse owners frequently mention cleanliness, color and cutting when it comes to choosing hay. Cleanliness should be the most important factor in selecting horse hay. Hay that contains dust or mold can inflame the respiratory tract. It is also possible for hay mold to affect other systems in the horse such as the digestive system and liver. Some horses suffer from a chronic respiratory condition that seriously impairs their ability to breathe normally. This condition, commonly known as heaves, worsens when horses are fed moldy or dusty hay. Horses with heaves are exercise intolerant and thus have little value except …

Reducing The Risk Of Bloat, Patty Scharko

Kentucky Alfalfa and Stored Forage Conference

Bloat refers to excessive accumulation of gas in the rumen. Bloat results when an animal can not eructate or "belch up" gases produced in the process of rumen fermentation. The gas may be in the free form or may be mixed with rumen contents in the form of froth. It occurs both on pasture and in feedlots and can be a major cause of death in cattle wherever intensive farming is practiced. Additional losses can include decreased milk production and reduced rate of gain. Although legumes may increase the opportunity for bloat to occur, fear of bloat should not keep …

Am-Pm Cutting Of Alfalfa, Garry D. Lacefield, Michael Collins, Jimmy C. Henning

Kentucky Alfalfa and Stored Forage Conference

Over the past twenty years of this Conference we have spent considerable time discussing "Alfalfa Harvest Management." We have discussed the importance of stage of maturity and its impact on quality on many occasions. We have presented research on many aspects of hay and haylage management. An overall theme for all the discussions has been "harvest for quality," with emphasis on saving the leaves during the entire harvesting process. Our recommendations have, are, and will continue to be centered around those management practices that will result in the greatest opportunity for preserving alfalfa quality from standing crop to feeding.
