Development Of Local Hay Association, Roger Sparrow, Eric Hinton, J. H. Ragland

Kentucky Alfalfa and Stored Forage Conference

The need for a Hay marketing "system" had been obvious to hay sellers and agricultural leaders in Larue County for some time. Five or six hay producers had been selling mainly alfalfa hay to truckers, who would transport the hay to a buyer and reap the profit. Hay was mostly sold by the bale and at a low price. Because of the land and soil type, Larue County had a good potential to produce alfalfa as a cash crop. The development of this potential was being limited by an unreliable and unprofitable market. Given these conditions, the development of a …

Alfalfa From The Consumer Standpoint, John Williams

Kentucky Alfalfa and Stored Forage Conference

Traditionally, horsemen in this part of the United States have fed grass hay mixed with good red clover hay to their horses in training as well as their horses on the farm. Knowing that legume hay is high in protein, horsemen found this is a good source of the needed protein for their animals no matter what activity they were engaged in. A few problems were found with clover hay. First of all, it was usually dusty and, if not made under ideal circumstances, the hay was dark and in some cases moldy. The hay could never be purchased in …

Innovations In Hay Harvesting And Storing, V. L. Lectenberg, D. A. Holt

Kentucky Alfalfa and Stored Forage Conference

Haymaking in the humid parts of the U.S. is the most risky operation that farmers engage in. Standing hay is extremely high in moisture and must be dried to at least 25% moisture less before it can be stored without spoilage. Most farmers rely on natural field drying processes to cure their hay. Natural drying is often slowed by high relative humidity. Rainfall frequently occurs before the hay has dried which further slows the drying process and can result in serious nutrient and yield losses. Haymaking is also a labor-intensive farming operation and, until recently, involved a large amount of …

Breaking The Alfalfa Yield Barrier, J. Paul Mueller

Kentucky Alfalfa and Stored Forage Conference

During the past one-hundred or so years, alfalfa production has spread and flourished in the United States. It has contributed to progress in many phases of the livestock industry.

No-Till Establishement Of Alfalfa, Harlan E. White, Dale D. Wolf

Kentucky Alfalfa and Stored Forage Conference

The no-till concept has been widely accepted in Virginia for corn and soybean production. However, alfalfa is still commonly established by plowing and tilling the soil into a fine seedbed. Each year many tons of productive topsoil is eroded by rainfall on those prepared seedbeds. The resulting gullies remain in the hayfield for the life of the stand to damage equipment and "rattle the teeth" of the operator.

Current Disease Problems In Alfalfa, William C. Nesmith

Kentucky Alfalfa and Stored Forage Conference

Alfalfa is attacked by many fungi, bacteria, viruses and nematodes which USDA estimates reduces hay yields by 24% annually in the U.S. Even greater losses occur in Kentucky. However, it is the diseases of the root and crown which cause the greatest damage because they limit the number of years a stand can remain productive.

Quality Alfalfa Seed Production In The West, Vern L. Marble

Kentucky Alfalfa and Stored Forage Conference

Alfalfa seed production in the western United States has become a specialized business, and can no longer be considered as a "catch crop" to be harvested along with a hay production program in historical production areas in the Plains and Rocky Mountain states which produced approximately 80 percent of all of the seed produced in the late 1940's and early 1950's. In 1981 the seven western states of California (47.8 percent), Idaho (12.2 percent), Nevada (8.7 percent), Washington (7.7 percent), Oregon (4.2 percent), Montana (4.5 percent), and Utah (3.2 percent) produced 87.5 percent of the total 1981 production of 117 …

Preliminary Groundwater Investigations In Relation To Soil Salinity At Fitzgerald, Western Australia, C J. Henschke

Resource management technical reports

This study investigated soil salinity problems in relation to new land releases at Fitzgerald near the south coast of Western Australia. Fairly widely spaced set of bores was established to compare the groundwater hydrology regimes beneath cleared and virgin land. A large storage of soluble salts (over 100 kgm-2 in some profiles) was measured in the pallid zone clays under both cleared and virgin land conditions. Seasonal fresh to brackish perched watertables were found to overlie highly saline deep waterbles at a number of valley sites on land which has been cleared for agriculture during the past 15 years. Salinity …

Nitrogen Value From Plowing A Sod, M. Scott Smith

Soil Science News and Views

With economic conditions as they are, crop producers need to effectively use all the resources available to them. To help offset high N fertilizer prices, one resource that may be used to significantly reduce production costs is the organic N accumulated in and on soils. When crops are planted into a tilled sod the requirement for added N fertilizer will usually be less than on land previously in row crops. The following discussion considers the processes and factors determining the quantity and availability of N in a sod, and offers some guidelines for estimating the N value of a sod.

Ground-Water Flow Along The Total Shoreline Of Austin Lake And Its Environmental Contribution To Pollution Of The Lake, William Thomas Williams

Dissertations

The vertical direction of ground-water flow in Austin Lake was determined by placing minipiezometers along the entire shoreline at fifty randomly selected sites. Ground-water samples were taken at each site and the specific conductivity of the water samples was determined along with the chloride and phosphate content. The data were analyzed to determine if there were any relationships among water movement, chemical content, and the presence or absence of an onshore septic tank. The minipiezometer data show that the primary direction of water movement through the sediment-water interface is downward but may become reversed at localized regions as conditions vary. …

Band Vs. Broadcast Application Of Fertilizer, Kenneth L. Wells

Soil Science News and Views

Current fertilizer prices coupled with other increased production costs have renewed interest in band applications of fertilizer as a means of lowering fertilizer costs while maintaining crop yields. Fortunately, much basic soil fertilizer research has been conducted over the years which provides an understanding of the relative merits of band and broadcast placement. The following discussion outlines the basic considerations involved in deciding which of these two placement methods may be more economically useful for specific crop production systems. To better understand these considerations, certain principles related to adding fertilizer to the soil should be kept in mind. These are …

A Geochemical Study Of The Rhododendron And Dalles Formations In The Area Of Mount Hood, Oregon, Marshall W. Gannett

Dissertations and Theses

The Miocene Rhododendron and Dalles Formations in the Mount Hood area are accumulations of chiefly pyroclastic andesitic material, largely confined to the Dalles-Mount Hood syncline. These very similar units are geographically separated by overlying andesites including the present Mount Hood cone, and past workers have suspected that they may share a common source. Prior to this study, few geochemical data were available for the Rhododendron and the Dalles Formations, compared to the well studied Columbia River basalts underlying them and the overlying Pliocene andesites. This geochemical study was designed to investigate certain aspects of the Rhododendron and Dalles Formations such …

A Search For Ddt Residues In The Juneau Icefield, Alaska, Jon Edwin Barber, Russell S. Adams Jr.

Journal of the Minnesota Academy of Science

The objectives of this study were: 1) to determine if DDT residues occurred in the ice of the Juneau Icefield, and 2) to devise a simple, inexpensive method of sampling glacial ice for pesticide residues. No DDT was found in the samples of ice collected strata spanning the 1963 to 1970 period. However, phthalate plasticizers were found in all samples and were assumed to be· due to contamination during collection. The elution time of the phthalate by gas chromatography was identical to that of p, p-DDT. Conversion of DDT to DDD by ultraviolet light was found to remove the phthalate. …

Buried Bedrock Topography Of The Cannon River System Around Northfield, Minnesota, Timothy D. Vick, Clinton A. Cowan, Daniel J. Packer

Journal of the Minnesota Academy of Science

A geophysical survey in the area of Northfield, Minnesota, involving electrical earth resistivity profiling and seismic refraction soundings, showed sizeable buried river channels in the bedrock in the Cannon River Valley which greatly increase in size downstream of Northfield. The channels upstream from the Northfield appear to be continuous and connect with the large buried channel between Northfield and Cannon Falls. The major buried valley deviates from the modern course of the Cannon River within the City of Northfield, but appears to follow elsewhere.

Structure And Influence Of The Tillamook Uplift On The Stratigraphy Of The Mist Area, Oregon, Moinoddin Murtuzamiya Kadri

Dissertations and Theses

Fifty three sedimentary samples were analyzed for their minor and trace element concentrations utilizing instrumental neutron activation analysis. Concentrations of Na, K, La, Sm and Sc, and their ratios appear to establish significant trends. The data suggest a major break from a granitic-metamorphic provenance and a volcanic component dominated provenance between the Cowlitz and Keasey Formations respectively. The provenance of the Astoria Formation indicates the presence of flood basalts.

A Preliminary Investigation Of The Lithological Characteristics Of The Troutdale Formation In Portions Of The Camas, Sandy, Washougal, And Bridal Veil Quadrangles, David Lee Cole

Dissertations and Theses

The study area encompasses a region of about 80 square kilometers, centered about Corbett, Oregon. Sieve analyses suggest that the Troutdale Formation is composed of a conglomerate, a coarse-grained sandstone, and a siltstone lithofacies. Measured sections data show that 56 to 60 percent of the Troutdale Formation's exposures are composed of the conglomerate lithofacies. The coarsegrained sandstone lithofacies makes up 34 to 38 percent, while the siltstone lithofacies makes up only 4 to 8 percent. Pebble count data show that the representation of basalt varies from 69 to 100 percent, with an average of 85 percent, while quartzite varies from …

Liming Needs Of Kentucky Soils, William O. Thom

Soil Science News and Views

A sound liming program is the first step in building and maintaining soil fertility. Lime lowers the acidity (raises pH) of soil and prevents the adverse effects of high concentrations of soluble aluminum, iron, and manganese on crop growth--effects often associated with acid soils. Maintaining a suitable pH assures adequate levels of calcium and magnesium. Liming an acid soil increases the availability of most essential plant nutrients, increases the efficiency of fertilizers, improves the effectiveness of some herbicides, and makes beneficial soil organisms more active.

Regional Hydrology Of The Green River-Moab Area, Northwestern Paradox Basin, Utah, United States Geological Survey

All U.S. Government Documents (Utah Regional Depository)

The Green River-Moab area encompasses about 7,800 square kilometers or about 25 percent of the Paradox basin. The entire Paradox basin is a part of the Colorado Plateaus that is underlain by a thick sequence of evaporite (salt) beds of Pennsylvanian age. The rock units that underlie the area have been grouped into hydrogeologic units based on their water-transmitting ability. Confining beds consist of evaporite beds of mostly salt, and overlying and underlying thick sequences of rocks with minimal permeability; above and below these confining beds are aquifers. The upper Mesozoic sandstone aquifer, probably is the most permeable hydrogeologic unit …
