Making Time For Agricultural And Life Science Research: Technical Change And Productivity Gains, Daniel L. Prager, Jeremy D. Foltz, Bradford L. Barham Jan 2014

Making Time For Agricultural And Life Science Research: Technical Change And Productivity Gains, Daniel L. Prager, Jeremy D. Foltz, Bradford L. Barham

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

This work analyzes the research productivity of agricultural and life science faculty in U.S. Land Grant research universities from 1975 to 2005. Production function estimations that control for inputs and demographic characteristics reveal significant improvements after 1980 in faculty research productivity per unit time, especially in the non-top ten universities. Because, however, time available to faculty for research has decreased substantially in the past three decades, overall journal article output per faculty did not increase after the 1980s. Our findings demonstrate large productivity increases but raise concerns about the optimal allocation of faculty time.

Biochemical Acclimation, Stomatal Limitation And Precipitationpatterns Underlie Decreases In Photosynthetic Stimulation Of Soybean(Glycine Max) At Elevated [Co2] And Temperatures Under Fully Open Airfield Conditions, David M. Rosenthala, Ursula M. Ruiz-Vera, Matthew H. Siebers, Sharon B. Gray, Carl J. Bernacchi, Donald R. Ort Jan 2014

Biochemical Acclimation, Stomatal Limitation And Precipitationpatterns Underlie Decreases In Photosynthetic Stimulation Of Soybean(Glycine Max) At Elevated [Co2] And Temperatures Under Fully Open Airfield Conditions, David M. Rosenthala, Ursula M. Ruiz-Vera, Matthew H. Siebers, Sharon B. Gray, Carl J. Bernacchi, Donald R. Ort

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The net effect of elevated [CO2] and temperature on photosynthetic acclimation and plant productivityis poorly resolved. We assessed the effects of canopy warming and fully open air [CO2] enrichment on (1)the acclimation of two biochemical parameters that frequently limit photosynthesis (A), the maximumcarboxylation capacity of Rubisco (Vc,max) and the maximum potential linear electron flux through photo-system II (Jmax), (2) the associated responses of leaf structural and chemical properties related to A, as wellas (3) the stomatal limitation (l) imposed on A, for soybean over two growing seasons in a conventionallymanaged agricultural field …

Invited Review: Overview Of New Traits And Phenotyping Strategies In Dairy Cattle With A Focus On Functional Traits, C. Egger-Danner, J. B. Cole, J. E. Pryce, N. Gengler, B. Heringstad, A. Bradley, K. F. Stock Jan 2014

Invited Review: Overview Of New Traits And Phenotyping Strategies In Dairy Cattle With A Focus On Functional Traits, C. Egger-Danner, J. B. Cole, J. E. Pryce, N. Gengler, B. Heringstad, A. Bradley, K. F. Stock

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

For several decades, breeding goals in dairy cattle focussed on increased milk production. However, many functional traits have negative genetic correlations with milk yield, and reductions in genetic merit for health and fitness have been observed. Herd management has been challenged to compensate for these effects and to balance fertility, udder health and metabolic diseases against increased production to maximize profit without compromising welfare. Functional traits, such as direct information on cow health, have also become more important because of growing concern about animal well-being and consumer demands for healthy and natural products. There are major concerns about the impact …

Exploring Integrated Crop–Livestock Systems In Different Ecoregions Ofthe United States, R Mark Sulc, Alan J. Franzluebbers Jan 2014

Exploring Integrated Crop–Livestock Systems In Different Ecoregions Ofthe United States, R Mark Sulc, Alan J. Franzluebbers

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Large-scale, energy-intensive, specialized production systems have dominated agricultural production inthe United States for the past half-century. Although highly productive and economically successful, thereis increasing concern with unintended negative environmental impacts of current agricultural systems.Production systems integrating crops and livestock have potential for providing additional ecosystem ser-vices from agriculture by capturing positive ecological interactions and avoiding negative environmentaloutcomes, while sustaining profitability. A diversity of ecologically sound integrated crop-livestock sys-tems have been and can be employed in different ecoregions: sod-based crop rotations, grazing covercrops in cash-crop rotations, crop residue grazing, sod intercropping, dual-purpose cereal crops, and agro-forestry/silvopasture. Improved technologies in conservation tillage, …

Soil And Water Conservation: Our History And Future Challenges, Douglas Karlen, Gary A. Peterson Jan 2014

Soil And Water Conservation: Our History And Future Challenges, Douglas Karlen, Gary A. Peterson

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Remembering our past is an essential first step into the future. Building on that philosophy, we summarize two presentations from a 2012 Soil Science Society of America (SSSA) symposium focused on soil management challenges in response to climate change to examine: (i) how the Soil and Water Management and Conservation Division evolved, (ii) how soil management research approaches have changed since the division was founded, and (iii) how division scientists are helping an increasing global population respond to a dynamic and changing climate. Our division roots and much of soil science in general were literally and figuratively grounded in field …

Selected Global Examples Of Cellulosic Cropping System Trends, Douglas Karlen, Marcelo Valadares Galdos, Sarita Candida Rabelo, Henrique Continho Junqueira Franco, Antonio Bonomi, Jihong Li, Shi-Zhong Li, Jaya Shankar Tumuluru, Leslie Ovard Jan 2014

Selected Global Examples Of Cellulosic Cropping System Trends, Douglas Karlen, Marcelo Valadares Galdos, Sarita Candida Rabelo, Henrique Continho Junqueira Franco, Antonio Bonomi, Jihong Li, Shi-Zhong Li, Jaya Shankar Tumuluru, Leslie Ovard

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Plant biomass has been recognized globally as an important link to a sustainable energy future because it can be grown universally and converted into liquid transportation fuels or other material through biochemical, thermochemical, or catalytic conversion processes. However, those potential benefits must be viewed in the context of other global societal needs (i.e., food, feed, fiber, potable water, carbon storage in ecosystems, and preservation of native habitats and biodiversity) that must also be met by plant biomass growing on a finite amount of arable land. The development of cellulosic feedstocks for biofuels and other bioproducts must be accomplished in an …
