Investigation Of Optimum Sample Number And Timing For Determining Pollution Loads, T. S. Soerens, Marc A. Nelson

Technical Reports

In order to determine the impacts of non point source (NPS) pollution and to develop Total Maximum Daily Loads (Tr\tfDLs), accurate measurements of pollution loads in streams are critical. The objectives of this study were to accurately detemline pollutant loads at two sites by intensive storm sampling, to develop sub-sampling and other data analysis techniques, to detemline the effect of sample interval on load calculation accuracy, and to find the minimum sample interval required to determine storm loads at a required accuracy. The two stream sites used were a 1st order and a 3rd order stream in the Illinois River …

Dealing With A Dry Season, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

Farmers' approaches to adverse seasonal conditions whether they be frost, flood or low rainfall should be to acquire as much information as possible on the immediate agronomic and financial situations and make a judgement on the longer term implications for the following seasons. Once the information has been acquired, in consultation with advisers, it is necessary to construct and implement agronomic and business strategies to deal with individual situations.

The agronomic and stocking options for the dry season supplied in this booklet deal with questions and issues arising from the Year 2000 season, which has been characterised by a mid …

Ground Water In Northwest Arkansas: Minimizing Nutrient Contamination From Non-Point Sources In Karst Terrane, R. K. Davis, J. V. Brahana, J. S. Johnston

Technical Reports

The purpose of the project is to evaluate the effectiveness of Best Management Practices (BPMs) in preventing non-point source contamination of the ground-water resources in the karst terrane of northwestern Arkansas. Limestone and dolomite aquifers in the region are highly vulnerable to contamination. Ground-water studies performed in the region during the last two decades indicate degradation of these carbonate aquifers by nutrients and bacteria. The expeditious growth of the poultry industry during this period, in combination with the inordinate population growth of the region constitute a threat to the ground-water resources from both point sources and non-point sources of contamination. …

Does Elevated Nitrogen And Sulfur Deposition Lead To Net Base Cation Losses In Northern New England Forest Soils?, Ivan J. Fernandez, Stephen A. Norton, Jeffrey Kahl, Lindsey E. Rustad

University of Maine Office of Research Administration: Grant Reports

The aims of this research are to continue treatment and monitoring of a paired watershed experiment at Bear Brook in northern Maine, with an emphasis on changes in soil base cations, particularly calcium. Base cation depletion is well-recognised as a potential problem in soils that have been subjected to acidic N deposition but few data exist from well-controlled, long-term experiments. The Bear Brook watershed has been periodically treated with ammonium sulfate since the fall of 1989 and is believed to be approaching N saturation. Since 1993 the relationship between base cations and strong acid anions has changed, such that labile …

Economics Of Using On-Farm Reservoirs To Distribute Diverted Surface Water To Depleted Ground Water Areas Of The Southern Mississippi Valley Region, Eric J. Wailes, Kenneth B. Young, James Smartt, Gail L. Cramer

Technical Reports

Rapid ground water depletion has become a significant problem for parts of the Southern Mississippi River Valley. In 1997, the Arkansas Soil and Water Conservation Commission (ASWCC) declared six counties in the Grand Prairie of Arkansas critical ground water areas. A proposed solution to the ground water depletion problem in this region is to divert surplus flows from the White River by a canal system to the farmer stakeholders. To make the system work, on-farm reservoirs will be needed to store and manage the diverted surface water for crop irrigation use during the growing season.

Changes In Alfalfa Breeding — Where Is Alfalfa Headed?, Becky Greenwald

Kentucky Alfalfa and Stored Forage Conference

Alfalfa didn't earn the title "Queen of the Forages" just because of its good looks on rolling hills or sweet smell at harvest. Alfalfa was first described nearly 2,500 years ago, in 490 B.C in the desert regions of what is now Iran. From the Middle East, alfalfa was taken into Europe and South America by invading armies, explorers, and missionaries.

Little Known Facts About Alfalfa, Don Ball

Kentucky Alfalfa and Stored Forage Conference

During the previous nineteen Kentucky Alfalfa Conferences, many topics pertaining to alfalfa have undoubtedly been addressed. In fact, some topics such as establishment techniques, varieties, and factors affecting yield are important enough that they have probably been discussed in one form or another during most of these conferences.

However, a twentieth-year state commodity conference is a milestone that deserves some special consideration, and which should justify inclusion of one or more unique topics on the program. This line of thinking led to idea that for this presentation it might be interesting to discuss some facts about alfalfa that are not …

Reducing Alfalfa Harvesting Losses, Michael Collins

Kentucky Alfalfa and Stored Forage Conference

In some areas of the country, producers store a substantial portion of their forage for winter feeding as silage or haylage. However, hay remains the most popular storage method for forage. Hay stores well for long periods and is better suited to cash sale and transportation than silage. Mechanical conditioning, which gained acceptance during the 1950's is probably still the greatest single change in hay harvesting and storage technology during this century. However, a number of other noteworthy changes and innovations have occurred in recent years which have helped to reduce the extent of losses during hay harvesting and storage.

Opportunities For Alfalfa As A Grazing Crop In Kentucky, Ken Johnson

Kentucky Alfalfa and Stored Forage Conference

Why do we continue to hear people talk about Alfalfa as a grazing crop? In my opinion there are two words that come to mind when I think of grazing Alfalfa, quality and yield. Alfalfa is without a doubt the highest quality forage we can graze. Alfalfa is also one of the highest yielding forages we can graze and maybe the highest yielding widely known and widely grown forage available to Kentucky farmers.

Hay Testing And New Marketing Program, Allen Johnson

Kentucky Alfalfa and Stored Forage Conference

The Kentucky Department of Agriculture (Hay & Grain Branch) Hay testing program is now entering its 13^th year of testing hay for Kentucky producers. The Department continues to use NIR forage analysis equipment. The program has made many improvements and much information has been gained. We continue to strive for quality control and producing accurate results. Recently, many new updates have occurred. New hardware and software have been added, along with the recent purchase of a second hay testing van. By placing a toll free call (1-800- 248-4628) to the Department of Agriculture in Frankfort, we will find a …

An Alfalfa Disease Calendar, Paul Vincelli

Kentucky Alfalfa and Stored Forage Conference

The following calendar provides producers and agricultural professionals with insights that may improve alfalfa production in several ways. First, knowing when to expect certain diseases improves one's ability to diagnose disease problems, which is a fundamental foundation for disease management. The many UK Extension Service publications on alfalfa as well as publications like the Alfalfa Analyst and the Compendium of Alfalfa Diseases, all are useful for diagnosis, but none provides a precise calendar of when to expect activity of alfalfa diseases in Kentucky. An alfalfa disease calendar can also provide occasional insights into timely management practices. For example, being …

Fertilizing Alfalfa For Profit, Monroe Rasnake, Steven G. Isaacs

Kentucky Alfalfa and Stored Forage Conference

Alfalfa has the potential for producing high yields of high quality forage with good management. A key component of good management is supplying plant nutrients in adequate quantities and proper balance. In Kentucky, this requires fertilizing soils with agricultural limestone, commercial fertilizers and/or animal manures. Good soil fertility is necessary for alfalfa stand establishment, high yields and long stand life.

Profitable Canola Production In The South Coastal Region 2000, David Eksteen

Bulletins 4000 -

Why grow canola in the South Coast Region? Canola is a member of the Brassicaceae family, which also includes mustard, turnip, wild radish, cauliflower, cabbage and broccoli. It is a winter growing oilseed that can be produced in most arable areas of Australia where winter crops are currently grown. Originally known as rapeseed using the species B. campestris, the species of B. napus have almost completely replaced this earlier species in all the areas where the crop is grown.

Stocking Rate Guidelines For Rural Small Holdings, Swan Coastal Plain And Darling Scarp And Surrounds, Western Australia, Dennis Van Gool, Ken Angell, Lindsay Stephens

Agriculture reports

Small rural holdings are often owned by people who want to pursue a semi-rural lifestyle but who are inexperienced in land management issues. This can result in landholders stocking their properties with animals at rates higher than the land resources can sustain, leading to degradation problems such as soil erosion, water pollution and damage to vegetation. This document provides information and guidelines to help planners, developers, local authorities and land owners determine the base stocking rates for rural small holdings on the Swan Coastal Plain and Darling Scarp and immediate surrounds. The advice utilises Agriculture Western Australia’s rural stocking rate …
