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.
Physiological determinants for pod yield of Peanut linesAuthor: A. Patanothai, N. Phakamas, S. Jogloy, K. Pannangpetch and G. Hoogenboom
The number of pods per unit area is an important component of pod yield of peanut. The goals of this study were to determine the relationships of (i) pod yield with number of pods per unit area and ...

Genomic changes in related species undergoing human-driven and natural selection are important and biologically interesting. The genus Agrostis is an ideal model for studying the evolution of plants ...
Agronomic performance of different pea cultivars under various sowing periods and contrasting soil structuresAuthor: Marie-Hélène Jeuffroy; Aurélie Vocanson ; Marie-Hélène Jeuffroy
Yield variability of spring pea (Pisum sativum L.) in farmers` fields is mainly due to soil compaction at sowing and abiotic stresses during the reproductive period. Winter peas flower earlier, and ...
Inheritance of resistance to stripe rust in three lines of soft red winter wheatAuthor: S.G. Markell, C.A. Griffey, E.A. Milus
Since 2000, stripe rust, caused by Puccinia striiformis Westend. f. sp. tritici Eriks., has been the most important foliar disease of wheat in the eastern United States. Three lines of soft red ...
Kansas senator honored with soil stewardship award
A long-time champion for agriculture, research, and the United States’ soil resources, Senator Pat Roberts, a Kansas Republican, will be presented today (Mar. 18) with the 2013 Excellence in Soil Stewardship Award by the Soil Science Society of America (SSSA). The award recognizes policy makers whose exemplary leadership has strengthened the U.S. agricultural enterprise and the natural resources that support it. A fourth generation Kansan who has served in the U.S. Senate since 1996, Roberts possesses an...
Organic Transitions Program (ORG)
The overall goal of the Organic Transitions Program (ORG) is to support the development and implementation of research, extension and higher education programs to improve the competitiveness of organic livestock and crop producers, as well as those who are adopting organic practices. In FY 2010, ORG will focus on environmental services provided by organic farming systems that support soil conservation and contribute to climate change mitigation. Practices and systems to be addressed include those associated with...
Crop performance matters when evaluating GHGs
Measuring the emission of greenhouse gases from croplands should take into account the crops themselves. That’s the conclusion of a study in the September-October issue of the Journal of Environmental Quality, which examined the impact of farm practices such as tillage on the greenhouse gas, nitrous oxide (N2O). Expressing emissions per unit of crop yield rather than on a more conventional areal basis produced very different results, says the study’s leader, Rod Venterea, research soil scientist with...
At the interface of humans and nature
A new book describes urban-rural interactions and the issues facing both people and ecosystems at those interfaces With the world population passing seven billion earlier this year, human activities are affecting more and more natural spaces as subdevelopments pop up in former corn fields and strip malls edge out forests. The ways in which people are changing and interacting with ecosystems is an emerging area of sustainability research, and scientists hope to understand how humans and nature can live in...
Helping quinoa brave the heat
Quinoa is a healthy food many know and love. As its popularity grows, more farmers are interested in planting it. However, the plant doesn’t do well in high temperatures, so plant breeders are trying to help. Many of the current methods for seeing if a quinoa plant is heat tolerant are time-consuming and expensive. Researchers, led by professor Kevin Murphy at Washington State University, have been looking into more efficient methods for determining heat tolerance in quinoa. “Temperatures above 95...
