Use Of Riparian Vegetated Filter Strips To Reduce Nitrate And Fecal Contamination In Surface Water, Mark S. Coyne, Robert L. Blevins, Rebecca A. Gilfillen

KWRRI Research Reports

This research assessed fecal bacteria trapping in surface runoff by grass filters and their potential to enhance NO₃^- removal via denitrification. Grass filter strips 9.0 m long trapped over 99% of the soil in surface runoff in 1992. Fecal coliform removal was less than 75%. In 1993, 9.0 and 4.5 m grass filter strips trapped 99 and 95% of the sediment, respectively. Fecal coliform trapping efficiency was 90% in 9.0 m grass filters and 75% in 4.5 m filters. Fecal streptococci trapping efficiency was 77% in 9.0 m grass filters and only 56% in 4.5 m filters. Fecal …

Correlating Soil Test Phosphorus Losses In Runoff, D. H. Pote, T. C. Daniel, P. A. Moore Jr., D. J. Nichols, D. R. Edwards, A. N. Sharpley

Technical Reports

Phosphorus in agricultural runoff is often a major cause of accelerated eutrophication of lakes and streams. Previous research has indicated that the amount of dissolved P (DP) in runoff is directly related to P content of the surface soil. Decades of fertilizer application at rates exceeding those of crop uptake have elevated soil test P (STP) levels in areas of intensive crop and livestock production, making this the major source of DP loss in runoff. The objective of our experiment was to relate STP content of Captina silt loam to P concentration and loss in runoff, and determine which STP …

Fundamental Principles Of Plant Pathology For Agricultural Producers, Paul C. Vincelli

Agriculture and Natural Resources Publications

All crop plants produced in Kentucky have the potential to become diseased under certain conditions. Diseases of crops can affect yield and/or quality of the harvested commodity. This can impact profitability and increase the risks of farming.

A plant is diseased when it is affected by some agent that interferes with its normal development. Some disorders are caused by noninfectious factors, such as temperature extremes or nutrient deficiencies. However, this publication focuses on diseases caused by infectious microorganisms.

Diseased plants exhibit a variety of symptoms. These can include stunting, yellowing, wilting, twisting, reddening, browning, blighting, root rot, fruit rot, …

Evaluating In Dual Economy Framework The Indian Industrial Performance During 1951-52 To 1989-90., R. Kavita Rao Dr.

Doctoral Theses

The primary goal of economic development is to achieve high rates of growth of outputs and incomes so to ensure high per as capita income and levels of living in the economy. In India, this was sought to be achleved, to a large extent, through a rapid expansion and growth of the industrial sector, as is evident in the emphasis placed on the industrialisation programmes in her various Five Year Plans. However, the growth of this sector has exhibited considerable ups and downs over the years, belying expectations. Quite expectedly, this has evoked substantial debate on the factors influencing and/or …

Interaction Of Price And Technology In The Presence Of Structural Specificities:An Analysis Of Crop Production In Kerala., Delampady Narayana Dr.

Doctoral Theses

The present study attempts to understand the agricultural economy of Kerala in terms of the structural characteristics specific to the state. This approach requires such aspects to be incorporated in the analysis, and also entails a shift from certain accepted modes of thinking and statistical treatment used in the analysis of field crops.The specificities arise from certain distinctive features on the demand and supply sides'. On the demand side, there is substi tution between rice and tapioca, and the two crops constitute the food group. The rest of the crops form the non-food group, and there is no substitution among …

Agricultural Tenancy In Palanpur., Naresh Kumar Sharma Dr.

Doctoral Theses

Institutions and arrangements governing the property and use of land are crucial to the development of productive forces. This is true, in particular, of triennial arrangements. The system of land tenures that prevailed during the colonial period was widely considered the main cause of economic stagnation at the time of India's independence (1947). It was also perceived as highly exploitative of the tenants. Thus, land reforms were accorded the highest priority by the new Indian Government. Soon all the State Legislatures started enacting land reform laws - starting with the Legislative Assembly of Bihar immediately after 1947 and the Legislative …

G93-1191 Glossary Of Water-Related Terms, William L. Kranz, Delynn Hay, James W. Goeke, David Gosselin

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide is a glossary of water quantity, quality and human health related terms involving water. Terms are defined in contexts that could affect Nebraskans. We depend upon water for our very existence. The impact of water quality and quantity issues has never been greater. Yet the terminology used to describe the water we drink, the water we provide to plants and animals, the water stored underground, in lakes, rivers, and oceans, is not well understood by many Nebraskans. This listing of water-related terms is intended to reduce the potential for misunderstanding presentations made by elected officials, environmental agencies and …

Rural Labour Markets And Seasonality: A Theoretical And Empirical Analysis., Anindita Mukherjee Dr.

Doctoral Theses

A large proportion of the labour force in India (that is, 66.56% of the main workers according to the Census of India, 1981) is engaged in agriculture. Just this simple fact would make a study of the functioning of agricultural labour markets highly important. But quite apart from this observation, there are several reasons for a detailed study of rural labour markets, particularly in the context of the problem of economic development.A major issue facing developing economies is industrial growth. The agricultural sector can foster growth by creating demand for industrial products, by providing a supply of certain primary inputs, …

Reconnaissance Survey Of Nitrate Concentrations In Ground Water In Howard And Pike Counties, Arkansas, Travis Thornton, Kenneth F. Steele

Technical Reports

In recent years, the rapid growth of poultry and hog production in Arkansas has caused concern regarding nitrate contamination of the ground water. In the study area of Pike and Howard Counties, the number of hogs has increased from 3,300 hogs in 1970 to 75,000 hogs in 1990. Poultr¥ production for the area has increased from 38,933,000 per year 1n 1970 to 62,774,000 per year in 1990. As animal production increases, so does the amount of animal waste that must be disposed. Hog production is of particular concern. Typical hog operations store concentrated animal waste in lagoons prior to land …

Determination Of Optimal Timing Of Poultry Waste Disposal By Meteorological, Hydrological, And Water Quality Modeling Techniques, D. R. Edwards, T. C. Daniel

Technical Reports

Approximately one million Mg of broiler litter were generated in conjunction with Arkansas' 1989 broiler production. Common practices for disposal of the waste have the potential to damage the quality of downstream rivers and lakes. This possibility is enhanced due to the concentration of broiler production in areas of the state with shallow soils, steep slopes, and limited suitable disposal area. Since the risk of pollution is greatest immediately following disposal and increases with rainfall depth and intensity, adverse water quality impacts may be mitigated by timing the application to coincide with low probability of surface losses of the nutrients …

The Relationship Between Soil Properties And No-Tillage Agriculture, Robert L. Blevins

Soil Science News and Views

I am highly honored to be invited to present the 3rd annual S.H. Phillips Distinguished Lecture on No-Tillage Agriculture. My interest and subsequent research efforts in the area of no-tillage agriculture began in 1969. Shirley Phillips encouraged my efforts through his interest and enthusiasm for this rather radical and new approach to farming without the use of tillage equipment. At that time, Harry Young, a western Kentucky farmer and pioneer of no-tillage agriculture along with Shirley, Jim Herron, Charlie Slack and other co-workers were excited about the potential of this new, innovative farming system and what it could do for …

G91-1025 Two Crops In One Year: Doublecropping, Russell Moomaw, Gary Lesoing, Charles A. Francis

University of Nebraska-Lincoln Extension: Historical Materials

Choice of crops, weed control, and other cultural practices for successful doublecropping are discussed here. Multiple cropping refers to growing two crops on the same field during the same year. One method of multiple cropping is doublecropping, which is when one crop is grown after the first crop is harvested. Prime USA regions for doublecropping are the eastern cornbelt, and southeastern and south central states where relatively long growing seasons and abundant rainfall occur. By contrast, shorter growing seasons and less frequent rainfall limit the potential for doublecropping in Nebraska. Irrigation is essential for successful doublecropping in Nebraska. Without irrigation, …

Disparities In Development: A Case Study Of Karnataka State (India)., Jayalaxmi Jayaram Dr.

Doctoral Theses

The Five Year Plans have recognised the need to bridge the developmental disparities across the regions and have formulated strategies for accelerated development of backward are as. However, the widening disparities between a few highly developed centres and vast areas of under development only bring out the inadequacies of the plans which are yet to integrate the resources of a region to its people. This study is an attempt to understand the spatial processes and patterns of development which offer an explanation to the intra/inter-regional contrasts in development. The study while high-lighting the importance of the Spatial approach has, in …

Multisectoral Model Of Income Distribution Poverty And Growth:Some Policy Exercies For Indian Economy., Debdas Bandyopadhyay Dr.

Doctoral Theses

The extent of poverty in any country depends upon two factors vlz, the average level of income anxd the degree of inequality in its distribution. The central theme in the continuing debate on the relationship between growth and poverty is whether past growth process in the developing countries has caused any signi.licant benefit to the poor. Kuznets (1955) was first to observe from cross country data that procosa of development is likely to be accompanied by increase in inequality, whhich would reverse itself only at a relatively advanced stage. This hypothesis has been subsequently confirned to some extent by several …

Agricultural Progress On The Ord, D A. Mcghie

Journal of the Department of Agriculture, Western Australia, Series 4

This is the first of occasional articles describing the experimental and commercial activity on the Ord River Irrigation Area (ORIA) in Western Australia's Kimberley region.

Against a background of extensive recources of land and water, a sometimes cimatic advantage and a complementary disadvantage of a remote location, agriculture on the Ord has swung from various monocultures to a broadly based and diversified production. In 1986, the value of agricultural production on the Ord will approach values equivalent to those of the cotton era for the first time since the demise of that industry 12 years ago.
