Increasing soybean yield is the top priority of the Iowa Soybean Association
(ISA) board, and higher yield means more profit for farmers. More than
$2.1 million is allocated each year to solve problems important to Iowa
soybean producers.
|
|
|
|
The Iowa Soybean Association
addresses issues facing producers today – such as limiting yield
loss from insects and diseases – while keeping an eye on the horizon
to look for emerging issues. The key to solving problems quickly is to
fund cutting-edge research at top universities like Iowa State University.
From honing management practices to finding new sources of SCN resistance,
to breeding soybeans for healthy hearts and world markets, Iowa’s
soybean producers are investing in areas that ensure they will remain
profitable and competitive in a global marketplace.
