Arkansas Agricultural Chemical Ground-Water Management Plan, Gerald King, Darryl Little, Tim Jessup, Charles Armstrong

Technical Reports

The Arkansas Agricultural Chemical Ground-Water Management Plan (SMP) is based on the Draft State Pesticide Ground- Water Management Plan Guidance and The Pesticides and Ground-Water Protection Strategy prepared by the U.S. Environmental Protection Agency (EPA). The need for a plan to protect ground water from contamination by agricultural chemicals and agents arises from evidence nationwide that using these chemicals can, in some instances, lead to contamination. In February 1988, EPA proposed a strategy to regulate certain pesticides by prohibiting their use in areas vulnerable to leaching unless a state develops and implements an acceptable management plan. The advantage of a …

Arkansas Rice Research Studies 1991, B. R. Wells

Arkansas Agricultural Experiment Station Research Series

The research reports in this publication represent one year of results; therefore, these results should not be used as a basis for longterm recommendations. Several research reports in this publication dealing with soil fertility also appear in Arkansas Soil Fertility Studies 1991, Arkansas Agricultural Experiment Station Research Series 421. This duplication is the result of the overlap in research coverage between the two series and our effort to inform Arkansas rice producers of all the research being conducted with funds from the rice check-off.

Evaluation Of The Water Quality Impacts Of Land Application Of Poultry Litter, T. C. Daniels, D. R. Edwards

Technical Reports

Evaluating the effect of land application of animal waste on water quality is fraught with inherent variability due to differing infiltration rates, slope, rainfall intensity and etc . Simulated rainfall technology has been used in erosion research for decades. Generally, this technology is used on plots of sufficient size (25 x 5 m) to develop rill and interrill erosion. The object of this investigation was to adapt and modify existing rainfall simulation technology used in soil erosion research for use in evaluating water quality impacts of land application of animal waste, and to test, evaluate and demonstrate it's scientific validity. …

Effect Of Land Application Of Poultry Waste On Pesticide Loss, T. C. Daniel, D. R. Edwards

Technical Reports

The poultry industry in Arkansas is a large, concentrated, growing industry that produces a high volume of fecal waste. Most of this waste is surface applied as pasture fertilizer. Pesticides are commonly used in the poultry industry for fly and litter beetle contro land are often a component of the surface-applied poultry waste. No information exists in the scientific literature regarding the transport of this pesticide component to nearby water supplies.Our research focused on cyromazine, a feed-through larvicide used to control flies in caged-layer hen houses. Tetrachlorvinphos and carbaryl are also used in poultry waste, but these pesticides have a …

Effects Of Polyacrylamide On Rangeland Soils And Plants, Saud Leily R. Al-Rowaily

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The objectives of this study were to determine the effects of two forms of polyacrylamide (PAM) conditioners (Cross-linked and Non-cross-linked PAM) on evaporation, saturated hydraulic conductivity, water retention, crust and crack formation of soils, seed germination, and seedling and tubeling growth.

The two PAM conditioners, 0.2% concentration by weight, were mixed with seven soils of different textures (sandy loam, silt, silty clay loam, silt loam, fine sand, medium sand, and coarse sand) to investigate the effects on evaporation, saturated hydraulic conductivity, and water retention. Soil samples of different textures were brought to field capacity and placed in a growth chamber …

Soil Heterogeneity And Its Exploitation By Plants, Robert B. Jackson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In this dissertation I first examine the ability of individual plants in the field to garner localized soil nutrients. I then measure actual soil variability around perennial plants and use various statistics to quantify the scale and degree of that variability.

Soil patches on opposite sides of Pseudoroegneria spicata tussocks were treated with distilled water or a nutrient solution containing N, P, or K in three field experiments. When P was augmented in the enriched soil patches, rates of P uptake increased significantly for roots from enriched patches compared with roots in control patches. Rates of ammonium and potassium uptake …

RIPS values offer guidance in pesticide selection and identify situations where a detailed site-specific evaluation should be conducted.

Compact – A Reclamation Soil Compaction Model Part Ii. Sensitivity Analysis And Applications, Ronald L. Bingner, Larry G. Wells

Biosystems and Agricultural Engineering Faculty Publications

COMPACT, a physically based, event-oriented compaction model, was developed as a management or research tool to evaluate the influence of a surface mining system on compaction of soil material during reclamation. Two systems of area mining reclamation operations were simulated by COMPACT. The first system involved scrapers and bulldozers and the second also included trucks. Scrapers or trucks were used to pick up and deposit the soil material. Bulldozers were then used to shape the site for reclamation. The simulated results were compared with measured results and show how equipment patterns and soil parameters can affect overall soil compaction. This …

Compact – A Reclamation Soil Compaction Model Part I. Model Development, Ronald L. Bingner, Larry G. Wells

Biosystems and Agricultural Engineering Faculty Publications

A physically based, event oriented soil compaction model, known as COMPACT, was developed as a management or research tool to evaluate the effect of surface mining systems on compaction of soil material during reclamation. Simulation of compaction throughout the soil profile at a surface mining reclamation site requires information describing how equipment moves on the site. The compaction processes that are caused by vehicles throughout the soil profile are described by applying the pressure distribution of the surface contact area of a tire or track to determine stresses in the soil profile. A virgin compression curve is then used to …

Effects Of Waterlogging On Crop And Pasture Production In The Upper Great Southern, Western Australia, J F. Wallace, G A. Wheaton, D J. Mcfarlane

Technical Bulletins

Separate estimates of the effect of waterlogging on cereal yields were made using rainfall and crop yield statistics, and remote sensing. Both methods showed that waterlogging costs tens of millions of dollars each year in lost crop production in the Upper Great Southern Statistical Division. The costs will be over $100 m in wet years. Losses in pasture production are likely to be of a similar magnitude, but are harder to quantify.

Dollars And Sense Of Alfalfa: Marketing Your High Yield, High Quality Alfalfa At High Prices, David C. Petritz

Kentucky Alfalfa and Stored Forage Conference

It seems every farmer wants to be in the commercial hay business--growing hay for the cash market. Have you ever stopped to think about the amount of hay that would be produced if everyone who talked about producing hay actually produced hay?

Chemical, Biological And Machinery Aids For Quality Haymaking, Michael Collins

Kentucky Alfalfa and Stored Forage Conference

Hay and pasture crops are critical to Kentucky Agriculture and to that of the entire temperate region of the US. The sale of cattle, calves and dairy products provide 29% of Kentucky's farm income compared with 23% for tobacco. Beef cow-calf enterprises comprise the majority of cattle numbers in the state, however, dairy production is also significant. A substantial horse industry exists in Kentucky which is an excellent market for high quality alfalfa hay. At present a substantial amount of alfalfa for horse feeding in the state is imported.

Alfalfa In My Cash Hay Operation, Nicky Baker

Kentucky Alfalfa and Stored Forage Conference

I'm Nicky Baker, a fifth generation farmer from the Fredonia Valley's area in Western Kentucky. My current farming operation consists of 65 acres alfalfa, 100 · acres of row crops, (basically a corn, wheat, soybean double-crop rotation) and 2.5 acres of burley tobacco. I also have a 50 cow beef herd.

I remember having alfalfa on our farm before the weevil days of the '60's caused farmers to stop growing it. In those days, most of the farms had alfalfa and the majority of them had dairy cattle. The grain explosion of the '70's further curtailed alfalfa acreage, thereby providing …

Alfalfa In My Beef Operation, Jay Quisenberry

Kentucky Alfalfa and Stored Forage Conference

I have had two failures seeding alfalfa in the past few years. Once I seeded into land that had been in no-till com only one year. I found that fescue came back into that stand of alfalfa and took it in several years. Another time I seeded alfalfa into land that had been in com for a few years but had not been seeded down properly. I thought I could no-till alfalfa in that piece of ground and there would not be too much competition. But I was wrong again. I realize that both times I could have come back …

Alfalfa In Beef Backgrounding Programs, G. D. Cantrill

Kentucky Alfalfa and Stored Forage Conference

Alfalfa can be a very important part of most beef backgrounding operations. Today I want to look at two ideas about alfalfa.

First, why we should consider making alfalfa our most important crop on a farm that's backgrounding. Secondly, what are some of the ways to best utilize the alfalfa we do produce?

We can say a lot of positive things about why alfalfa can be important to a beef backgrounder. In preparing for this presentation, I talked with several producers about why they grow and feed alfalfa. Most often I came away with the thought: Alfalfa improves cash flow.

Advances In Grazing Alfalfa, Charles T. Dougherty

Kentucky Alfalfa and Stored Forage Conference

Many farmers are reluctant to develop a new enterprise based on the grazing of alfalfa if they have had no experience with grazing of this species. Their first negative reaction is usually based on their fear of legume bloat. Often their second reaction is that grazing will destroy the alfalfa stand in short order. Another response is that grazing is a wasteful and inefficient use of a valuable resource generating less income than conventional uses, such as hay and silage. Another reaction is based on the fear Alfalfa grazing, according to other sceptics, also requires lots of capital for fencing …

Is Ridomil Recommended When Seeding Alfalfa?, Paul C. Vincelli

Kentucky Alfalfa and Stored Forage Conference

Ridomil 2E® fungicide received a federal label in 1991 for control of seedling diseases of alfalfa caused by Pythium and Phytophthora fungi. Pythium fungi are widespread in Kentucky soils but can be controlled with Apron^® seed treatment. Phytophthora is less common in Kentucky soils. Where present, Phytophthora can usually be controlled with a combination of resistant varieties and Apron seed treatment. Occasionally, yield increases may be observed using Ridomil in fields highly infested with Phytophthora. However, broadcast applications of Ridomil at seeding are not recommended for most alfalfa fields in Kentucky.

Alfalfa Varieties, Jimmy C. Henning, Linda Brown, Garry D. Lacefield, Leonard M. Lauriault

Kentucky Alfalfa and Stored Forage Conference

Alfalfa (Medicago sativa) is the highest yielding, highest quality legume forage crop raised in Kentucky. This crop forms the basis of Kentucky's cash hay enterprise and is an important component in dairy, horse, beef and sheep diets. In 1990, 320,000 acres of alfalfa were produced in Kentucky, averaging 3.4 tons of dry matter yield per acre. At $75 per ton, the value of this alfalfa to Kentucky farmers would be $81.6 million.

This report will provide current yield data on alfalfa varieties currently in the Kentucky Alfalfa Variety Trials. Also, guidelines on selecting alfalfa varieties will be discussed.

Effects Of Tillage And Grass Filter Strips On Surface Runoff Of Water, Nitrate, Sediment, And Atrazine, C. E. Madison, Robert L. Blevins, Wilbur Frye

Soil Science News and Views

The contamination of streams and other natural bodies of water through agricultural runoff has become a very important environmental issue. Surface water runoff can contain heavy loads of sediment and/or agricultural chemicals, such as nitrogen and atrazine. Conservation tillage methods with vegetative filter strips downslope from cropped fields help· to combat this problem. Conservation tillage has proven effective in decreasing erosion by decreasing exposure of the soil surface to rainfall. Vegetative filter strips provide an area where sediment and agricultural chemicals from cropland can be deposited before the runoff reaches a body of water.
