Gypsum is a Reliable Source of Sulfur for Soybean Production

May 19, 2025

Soybeans (Glycine max) are a crucial global protein source, making their nutritional enhancement essential for agriculture and food production. Sulfur improves the quality of soybeans by increasing sulfur-containing amino acids, and the total content of sulfur in seeds may serve as a proxy for amino acid levels. However, optimizing sulfur availability through sustainable management remains underexplored.

A recent study in Agricultural & Environmental Letters investigated whether integrating cover crops and flue-gas desulfurization gypsum—a by-product of coal combustion—could enhance soybean nutrition.

Video: Agriculture Secretary Rollins Speaks at American Farm Bureau Federation Convention in Anaheim

One of the highlights at the 2026 American Farm Bureau Federation Convention in Anaheim, California, was an address by U.S. Secretary of Agriculture Brooke Rollins. During her remarks, she thanked America’s farmers and ranchers and said the Trump Administration is fully aware that food security is national security.

She also acknowledged the challenging times in Farm Country with low commodity prices and high input costs and said that’s why the President stepped in to help with the recent Bridge Assistance Program.

Montana Farm Bureau Federation Executive Vice President Scott Kulbeck says that Farm Bureau members are appreciative of the help and looks forward to working with the American Farm Bureau Federation and its presence in Washington, DC to keep farmers and ranchers in business.

Secretary Rollins said the Trump Administration is also committed to helping ranchers build back America’s cattle herd while also providing more high-quality U.S. beef at the meat case for consumers.

And she also announced more assistance for specialty crop producers who only received a fraction of the $12 billion Farmer Bridge Assistance (FBA).

It’s important to note that producers who qualify for Farmer Bridge Assistance can expect the Farm Service Agency to start issuing payments in late February. For more information, farmers and ranchers are encouraged to contact their local USDA Service Center.
