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 tiny pest can cause huge losses to soybean farmers.
A (wo)man is only as good as his or her tools. In the case of soil scientists, they are only as good as the tools and methods they use. And when it comes to estimating soil organic carbon stocks, new research shows not all ...
Some relationships can be complicated. Take the one between sweet potato crops and soil nitrogen, for example.
Plants can't do without phosphorus. But there is often a 'withdrawal limit' on how much phosphorus they can get from the soil. That's because phosphorus in soils is often in forms that plants can't take up. That affects how ...
Add just enough fertilizer, and crops thrive. Add too much, and you may end up with contaminated surface and groundwater.
Healthy soil contributes to healthy crops. Farmers know this, so they do what they can to ensure their soil is in good shape. They send samples of their soil for lab testing to find out if it is low in any important nutrients. ...
Take a trip down into the soil beneath a field of crops. You won't find just dirt, water, and creepy-crawlies. You'll also find reactions that remind you of high school chemistry lab.
A heat wave sweeps through a city and people swelter, running indoors to find air conditioning. But crops out in a field aren't so lucky. For them, there is no escape.
The world produces more corn by weight than any other cereal crop. Corn, also known as maize, is a staple food in many countries. But farmers growing corn face many challenges, such as drought, diseases, and pests.
Outside Asia, no other country produces as much rice as does Brazil. It is the ninth largest rice producer in the world. Average annual yields are close to 15 million tons.
