The American Society of Agronomy (ASA) is a scientific and professional society of agronomists and scientists of related disciplines, principally in the United States but with a large number of non-U.S. members as well. It was founded in 1907 with the objective of 'the increase and dissemination of knowledge concerning soils, crops, and the conditions affecting them.' One of its founding members was Charles Piper, who would become its president in 1914. The first president was Mark A. Carlton and the first annual meeting was held in Washington, D.C., in 1908. Two daughter societies were subsequently formed, the Soil Science Society of America and the Crop Science Society of America. The ASA is headquartered in Madison, Wisconsin, and publishes a number of scientific journals. The ASA holds annual meetings attended by thousands of its members.
A tale of two (soil) cities
As we walk along a forest path, the soil beneath our feet seems like a uniform substance. However, it is an intricate network of soil particles, pores, minerals, soil microbes, and more. It is awash in variety.
Recycled water, salt-tolerant grass a water-saving pair
Plants need water. People need water. Unfortunately, there's only so much clean water to go around—and so the effort begins to find a solution.
Better switchgrass, better biofuel
Using switchgrass to produce biofuel is one way to decrease the United States' dependence on oil, but growing it and making it profitable can be complicated.
When trees aren't 'green'
Most of us don't consider forests a source of pollution. As natural bodies, they should be good for the environment. But a recent study in Japan shows that older cedar and cypress plantations are causing ...
Food or fuel? How about both?
In the United States, federal mandates to produce more renewable fuels, especially biofuels, have led to a growing debate: Should fuel or food grow on arable land? Recent research shows farmers can successfully, ...
New planning toolset gives farmers more options for improving water quality
With agriculture increasingly on the hook to improve water quality, curb erosion, and meet other environmental goals, it only makes sense to target soil and water conservation practices to the places on the ...
Urban gardeners can take simple precautions to avoid contaminants
Green thumbs, do not fret. Pockets of soil in urban areas are still available for the increasingly popular practice of urban gardening.
A model approach for sustainable phosphorus recovery from wastewater
A new approach to wastewater treatment may be key in efforts to reduce, reuse, and recycle. Moreover, it can be profitable.
Going with the flow? Research provides better understanding of soils and water
When it comes to soil and water, predictability is important—but difficult.
Soils help control radioactivity in Fukushima, Japan
Radiation suddenly contaminates the land your family has farmed and lived on for generations. Can soil play a role in protecting crops and human health?
Tracing the course of phosphorus pollution in Lake Pepin
In recent years, many lakes in the upper Midwest have been experiencing unprecedented algae blooms. These blooms threaten fish and affect recreational activities. A key culprit implicated in overgrowth of algae in lakes is ...
'Tailored' water—the latest in lawn care
In Santa Fe, Albuquerque, and other major cities in New Mexico, nearly every public golf course is now watered with treated municipal wastewater rather than precious potable water supplies. Across the U.S. ...
Grain legume crops sustainable, nutritious
Popular diets across the world typically focus on the right balance of essential components like protein, fat, and carbohydrates. These items are called macronutrients, and we consume them in relatively large ...
Growing camelina and safflower in the Pacific Northwest
A recent study published in Agronomy Journal provides information important to farmers growing oilseed crops. In the study, camelina and safflower were grown in three-year rotations with winter wheat and su ...
Food security increased by new scientific model in agricultural production
Farmers are used to optimizing crop production on their own lands. They do soil tests to choose the right amount of fertilizers to apply, and they sometimes plant row crops on some fields while keeping others in pasture.
