Cover Crop Effect On Subsequent Wheat Yield In The Central Great Plains, David C. Nielsen, Drew J. Lyon, Robert K. Higgins, Gary W. Hergert, Johnathon D. Holman, Merle F. Vigil Oct 2016

Cover Crop Effect On Subsequent Wheat Yield In The Central Great Plains, David C. Nielsen, Drew J. Lyon, Robert K. Higgins, Gary W. Hergert, Johnathon D. Holman, Merle F. Vigil

David C. Nielsen

Crop production systems in the water-limited environment of the semiarid central Great Plains may not have potential to profitably use cover crops because of lowered subsequent wheat (Triticum asestivum L.) yields following the cover crop. Mixtures have reportedly shown less yield-reducing effects on subsequent crops than single-species plantings. This study was conducted to determine winter wheat yields following both mixtures and single-species plantings of spring-planted cover crops. The study was conducted at Akron, CO, and Sidney, NE, during the 2012–2013 and 2013–2014 wheat growing seasons under both rainfed and irrigated conditions. Precipitation storage efficiency before wheat planting, wheat ...


Cover Crop Biomass Production And Water Use In The Central Great Plains, David C. Nielsen, Drew J. Lyon, Gary W. Hergert, Robert K. Higgins, Johnathon D. Holman Aug 2015

Cover Crop Biomass Production And Water Use In The Central Great Plains, David C. Nielsen, Drew J. Lyon, Gary W. Hergert, Robert K. Higgins, Johnathon D. Holman

David C. Nielsen

The water-limited environment of the semiarid Central Great Plains may not produce enough cover crop biomass to generate benefits associated with cover crop use in more humid regions. There have been reports that cover crops grown in mixtures produce more biomass with greater water use efficiency than single-species plantings. This study was conducted to determine differences in cover crop biomass production, water use efficiency, and residue cover between a mixture and single-species plantings. The study was conducted at Akron, CO, and Sidney, NE, during the 2012 and 2013 growing seasons under both rainfed and irrigated conditions. Water use, biomass, and ...


Cover Crop Mixtures Do Not Use Water Differently Than Single-Species Plantings, David C. Nielsen, Drew J. Lyon, Gary W. Hergert, Robert K. Higgins, Francisco J. Calderon, Merle F. Vigil Jan 2015

Cover Crop Mixtures Do Not Use Water Differently Than Single-Species Plantings, David C. Nielsen, Drew J. Lyon, Gary W. Hergert, Robert K. Higgins, Francisco J. Calderon, Merle F. Vigil

David C. Nielsen

Recent recommendations advocating the use of cover crop mixtures instead of single-species in semi-arid environments require rigorous scientific studies. One of those stated benefits is greatly reduced water use by cover crops grown in mixtures. The objectives of this study were to characterize soil water extraction patterns and determine water use of cover crops grown in single species plantings and in a 10-species mixture and to compare cover crop water use to evaporative water loss from no-till fallow. The study was conducted at Akron, CO, and Sidney, NE, during the 2012 and 2013 growing seasons on silt loam soils. At ...

Travelling In Cuba, Fathi Habashi Feb 2013

Travelling In Cuba, Fathi Habashi

Fathi Habashi

Contact with Cuban scientists was established in 1986 when two researchers from Centro de Investigaciones para Industria Minero Metalurgica in Havana visited Laval University to get acquainted with research activities in the area of extractive metallurgy. This was followed in early 1987 by two more researchers from the same centre. Invitations were then received in late 1987, 1989, and 2008 to visit the nickel refineries in Cuba and to hold seminars at the University of Havana. The present report outlines these activities.

Container Plants For Desert Restoration, David A. Bainbridge Jan 2013

Container Plants For Desert Restoration, David A. Bainbridge

David A Bainbridge

Container planting is essential for most desert restoration work because direct seeding is rarely successful. The containers best suited for desert planting are often taller (deeper) to facilitate root development. Fertilizer management, inoculation, irrigation and pruning can be used to maximize root growth with minimal shoot development.

Magnesium: An Overlooked Nutrient?, Robert Mikkelsen Jun 2011

Magnesium: An Overlooked Nutrient?, Robert Mikkelsen

Robert Mikkelsen

Magnesium nutrition of plants is frequently overlooked and shortages can adversely impact plant growth. Many essential functions require adequate Mg supplies... the most visible being its role in chlorophyll and photosynthesis... but less visible reactions are also dependent on an adequate supply of Mg. When needed, a variety of soluble and slowly soluble Mg sources are available to meet crop demands.


Metalurgia Extractiva Y Política Nacional, Fathi Habashi Jan 2011

Metalurgia Extractiva Y Política Nacional, Fathi Habashi

Fathi Habashi

Should a country export its mineral wealth in form of concentrates or should it locally treat its ores to produce metals as final products? In the past centuries pyrometallurgy was the only route to extract metals from ores and this required a large capital investment many countries could not afford to raise. This situation encouraged marketing of concentrates. Today, metallurgists have the option to use the hydrometallurgical route to process ores and concentrates at a reasonable capital investment. This opened the way to the possibility of processing ores locally. When need arises to increase production new units can be added ...


Leaching Mechanism Of Semiconducting Minerals, Fathi Habashi Dec 2010

Leaching Mechanism Of Semiconducting Minerals, Fathi Habashi

Fathi Habashi

The mechanism of leaching of semiconducting minerals such as PbS, ZnS, UO2, etc., has been the subject of intensive speculation by hydrometallurgists in the early 1950s. The electrochemical mechanism proposed in 1970 by the author in volume 2 of his Principles of Extractive Metallurgy avoids the assumption of forming intermediate complexes that cannot be isolated or identified.


Metals: Typical And Less Typical, Transition And Inner Transition, Fathi Habashi Mar 2010

Metals: Typical And Less Typical, Transition And Inner Transition, Fathi Habashi

Fathi Habashi

While most chemists agree on what is a metal and what is a non-metal there is a disagreement with respect to what is a metalloid and what is a transition metal. It is believed that this problem can be solved if two new terms are adopted: typical and less typical metals. These new terms will also help reconcile the European Periodic Table versus the North American regarding numbering of groups as well as the IUPAC numbering which could be as well abandoned in favour of group names as will be shown in the manuscript.

Aqua Science Through The Ages. An Illustrated History Of Water, Fathi Habashi Jan 2010

Aqua Science Through The Ages. An Illustrated History Of Water, Fathi Habashi

Fathi Habashi

Water a component of the Four Elements considered by the ancient philosophers as essential for survival, played, and is still playing an essential role in society. Great civilizations in ancient times developed along great rivers. The ancient peoples knew how to manage water supplies by digging canals, controlling floods, and using water for irrigation. They designed equipment that used water to measure the time, to determine the density of solids, to fight fires, and to create vacuum. Modern engineers exploited water flow to design and construct huge hydroelectric power stations. Waterways and navigation systems were also an essential element for ...

Science, Technology, And Society, Fathi Habashi

Fathi Habashi

Science, technology, and society is a vast and complex question. It is discussed here from five points: social responsibility of scientists, migration and movement of scholars, philanthropy and its role in education and culture, enlightened despots and their influence on science and culture, and finally the social aspects of mining. The book is meant for the general reader but can benefit scientists as well. It is fully illustrated with colored pictures. It is hoped that it will serve as an introduction to this field to the young generation and inspire them to serve society.


Climate Change And Freshwater Resources, Noah D. Hall, Bret B. Stuntz, Robert H. Abrams Jan 2008

Climate Change And Freshwater Resources, Noah D. Hall, Bret B. Stuntz, Robert H. Abrams

Noah D Hall

The Earth’s climate is warming. This is the unequivocal conclusion of climate scientists. Despite the complexities of climatology, certain consistent trends emerge with implications for water availability: as the world gets warmer, it will experience increased regional variability in precipitation, with more frequent heavy precipitation events and more susceptibility to drought. These simple facts will have a profound impact on freshwater resources throughout the United States, as the warmer climate will reduce available water supplies and increase water demand. Unfortunately, current water law and policy are not up to the new challenges of climate change and resulting pressures on ...


Risks, Farmers’ Suicides And Agrarian Crisis In India: Is There A Way Out?, Srijit Mishra Jan 2008

Risks, Farmers’ Suicides And Agrarian Crisis In India: Is There A Way Out?, Srijit Mishra

Srijit Mishra

Poor returns to cultivation and absence of non-farm opportunities are indicative of the larger socio-economic malaise in rural India. This is accentuated by the multiple risks that the farmer faces – yield, price, input, technology and credit among others. The increasing incidence of farmers’ suicides is symptomatic of a larger crisis, which is much more widespread. Risk mitigation strategies should go beyond credit. Long term strategies requires more stable income from agriculture, and more importantly, from non-farm sources. Private credit and input markets need to be regulated. A challenge for the technological and financial gurus is to provide innovative products that ...


The Potential Role Of Probiotics In Reducing Poverty-Associated Infections In Developing Countries, Kingsley C. Anukam Oct 2007

The Potential Role Of Probiotics In Reducing Poverty-Associated Infections In Developing Countries, Kingsley C. Anukam

Kingsley C Anukam

Probiotics are defined by the Food and Agricultural Organization/ World Health Organization as “live microorganisms which when administered in adequate amounts confer a health benefit on the host” [1]. The potential benefits of their use have not been adequately investigated, especially in the developing world. Japan introduced Yakult, a probiotic fermented food drink in 1935, and in the Northern hemisphere, research and use of probiotics has gained an unprecedented momentum in the last decade [2]. Use of probiotics is not uncommon in Europe [3], but in many developing countries use of probiotics in its present definition is a foreign concept ...
