Soil Science Society of America (SSSA)
The Soil Science Society of America (SSSA) is a progressive international scientific society that fosters the transfer of knowledge and practices to sustain global soils. Based in Madison, WI, and founded in 1936, SSSA is the professional home for 6,000 members and 1,000 certified professionals dedicated to advancing the field of soil science. The Society provides information about soils in relation to crop production, environmental quality, ecosystem sustainability, bioremediation, waste management, recycling, and wise land use.
Runoff Phosphorus loss immediately after poultry manure application as influenced by the application rate and tillageAuthor: Antonio P. Mallarino, Daniel E. Kaiser, Mazhar U. Haq and Brett L. Allen
Excessive or N-based application of poultry manure for crops may result in significant risk of P loss with surface runoff. This study assessed P loss immediately after poultry manure application to ...
Genetic improvement of Sorghum as a biofuel feedstock: II. QTL for stem and leaf structural carbohydratesAuthor: Stephen Kresovich, Seth C. Murray, William L. Rooney, Sharon E. Mitchell, Arun Sharma, Patricia E. Klein and John E. Mullet
Digestion and fermentation of lignocellulosic biomass (i.e., structural carbohydrates) are predicted to deliver higher yields of energy per hectare than sugar and starch (nonstructural ...
Impacts of chemical amendment and plant growth on lead speciation and enzyme activities in a shooting range soil: An X-ray absorption fine structure investigationAuthor: Yohey Hashimoto, Hiroki Matsufuru, Masaki Takaoka, Hajime Tanida and Takeshi Sato
In situ chemical immobilization is a practical remediation technology for metal-contaminated soils because of its capability to reduce cost and environmental impacts. We assessed the immobilization ...
Mapping and confirmation of a new allele at Rpp1 from soybean PI 594538A conferring RB lesion–type resistance to soybean rustAuthor: Nanda Chakraborty, Joe Curley, Reid D. Frederick, David L. Hyten, Randall L. Nelson, Glen L. Hartman and Brian W. Diers
Soybean rust, caused by Phakopsora pachyrhizi (H. Sydow & Sydow), is a destructive soybean [Glycine max (L.) Merr.] disease and identification of new resistance genes is essential for effective ...
Organic and conventional production systems in the wisconsin integrated cropping systems trials: i. Productivity 1990–2002Author: Joshua L. Posner; Jon O. Baldock; Janet L. Hedtcke
During the last half-century, agriculture in the upper U.S. Midwest has changed from limited-input, integrated grain–livestock systems to primarily high-input specialized livestock or grain systems. ...
Teaching communication and information literacy skills
Undergrads often take communication courses unrelated to their major or discipline. The Iowa State University Department of Horticulture teamed up with the Library and English Departments to develop a course section to teach students to research and understand literature searchers and incorporate them into papers and posters.Andrea L. Dinkelman, Jeanine E. Aune, and Gail R. Nonnecke, Iowa State University faculty from the library and the Departments of English and Horticulture, developed the section in an...
Importance of ag research highlighted with funding
The continuing importance of agricultural research is evident with the proposed funding for the Agriculture and Food Research Initiative (AFRI) in President Obama’s FY 2012 budget. Strong AFRI funding will support land grant, USDA, and industry scientists in meeting global challenges including food security needs, maintaining soil ecosystem health, adapting crops to a changing climate, and producing renewable energy. In the President`s FY 12 budget AFRI funding increases from $262 million to $325...
Free webinar: Managing nutrients after the drought
Join a panel of experts as they discuss how to practice good nutrient management in the wake of this year`s drought Sponsored by the Agricultural Nutrient Policy Council and hosted by the American Society of Agronomy The drought of 2012 will long be remembered for its devastating effects on crops across a huge swath of North America`s most productive soils. And while late summer rains eased conditions for many, water is still critically short across large areas. Following such a different situation, it will...
Corn silage hybrids and seeding rates
Recent studies report that corn hybrids released in the late 2000s, especially Bt hybrids, require higher seeding rates than commercial hybrids released in the 1990s to reach maximum yields. Expectedly, corn seeding rates in the USA have increased significantly in the past 10 years. However, limited data is available on silage yield and quality responses of recently released hybrids to seeding rates.Cornell scientist William Cox investigated the response of eight hybrids (three Bt and a non-Bt hybrid, two brown...
Tillage and reduced-input rotations affect runoff from agricultural fields
A new study from researchers at the USDA Agricultural Research Service provides information about runoff under different management practices and can help farmers choose the practice that is best for them. No-till management practices can reduce soil erosion, but evidence suggests they can also lead to increased runoff of dissolved phosphorus from soil surfaces. Meanwhile, farmers looking to avoid herbicides often have to combat weeds with tillage, which causes erosion. With all of the tradeoffs of different...
