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.
Phytoextraction of Phosphorus-enriched grassland soilsAuthor: Caroline van der Salm, Wim J. Chardon, Gerwin F. Koopmans, Jantine C. van Middelkoop, Phillip A.I. Ehlert
Received for publication February 7, 2008. High soil P contents in agricultural soils in the Netherlands cause excessive losses of P to surface waters. The reductions in P application rates in the ...
Parameterization and evaluation of the aquacrop model for full and deficit irrigated cottonAuthor: Hamid J. Farahani, Gabriella Izzi, Theib Y. Oweis

Simulating yield response of quinoa to water availability with aquacropAuthor: Sam Geerts, Dirk Raes, Magali Garcia, Roberto Miranda, Jorge A. Cusicanqui, Cristal Taboada, Jorge Mendoza, Ruben Huanca, Armando Mamani, Octavio Condori, Judith Mamani
The modeling of yield response to water is expected to play an increasingly important role in the optimization of crop water productivity (WP) in agriculture. During 3 yr (2004–2007), field ...
The putative mesoamerican domestication center of phaseolus vulgaris is located in the lerma–santiago basin of MexicoAuthor: Paul Gepts, Myounghai Kwak, James A. Kami
Mesoamerican food agriculture is defined by the milpa cropping system, consisting of maize (Zea mays L.), common bean (Phaseolus vulgaris L.), and squash (Cucurbita spp.). In recent years, a ...
Science societies support current Farm Bill recommendations
Movement on the 2012 Farm Bill, as previously planned by the Senate Agriculture Committee on Wednesday, April 25 is currently being rescheduled. But the American Society of Agronomy (ASA), Crop Science Society of America (CSSA), and Soil Science Society of America (SSSA) is applauding Senate Agriculture Committee Chairwoman Debbie Stabenow and Ranking Member Pat Roberts for crafting the bipartisan effort to date, and especially continuing investment in critical agricultural research, along with acknowledging the...
Microbes play important role in soil’s nitrogen cycleAuthor: Susan V. Fisk
Under our feet, in the soil, is a wealth of microbial activity. Just like humans have different metabolisms and food choices, so do those microbes. In fact, microbes play an important role in making nutrients available to plants. A recent review paper from Xinda Lu and his team looks at different roles that various soil microbes have in soil’s nitrogen cycle. Lu is a researcher at Massachusetts Institute of Technology. According to Lu, “Soil microbes catalyze most of the transformations of soil...

Cotton’s global genetic resources
A multinational collaborative effort among cotton scientists produced a report on the status of the global cotton genetic resources. According to the report, cotton production relies primarily on two species, with 48 other species catalogued in the various seed collections that have largely been poorly characterized and under-utilized in crop improvement efforts.Based on the findings of this report, there are four wild species not conserved or maintained within any of the eight collections. The report also...
New book explores history, future of international agriculture
For more than 100 years, scientists have made the American Society of Agronomy (ASA) a force for international change to improve agriculture. A new book, The International Dimension of the American Society of Agronomy: Past and Future, provides both a historical overview and a glimpse of the future of the world of agronomy. The contributions of science to agriculture over the last century are impossible to ignore. Despite a fourfold increase in world population and higher economic demand per person, efficiency...
