Iron Deficiency Chlorosis (IDC) affects growers across the Upper Midwest, including Minnesota, and parts of North and South Dakota. This yield-robbing condition should be top-of-mind for growers knowing that its effects have the potential to be devastating. However, it’s important to remember that IDC is avoidable. Growers can take steps today to identify and prevent IDC in their soybeans tomorrow.
Iron Deficiency Chlorosis can be characterized by yellow leaves and dark green (interveinal chlorosis) veins, decreased plant vigor, stunted growth, leaf death, and decreased yield, which results when soybeans cannot access iron from the soil.
Soybeans are affected by IDC when they are unable to access optimal amounts of soluble iron. Without a healthy amount of iron uptake, the plants often develop chlorotic yellow leaves and dark green veins often referred to as interveinal chlorosis. The plants have less vigor, leading to issues with growth and yield.
These symptoms will typically first manifest on the youngest of the top leaves.
When IDC is severe, the leaf edges may die. This necrosis may advance to the point where the leaves fall off the plant and the death of the growing point, decreasing the tissue available for photosynthesis.
If IDC is left untreated or without preventative action, yield loss can be devastating and leave the field prone to IDC in the future. Although there may be ample iron in the soil, soil conditions can make it inaccessible to the developing plant.
Chelated with the purest ortho-ortho EDDHA that exists, Soygreen brands are the leading micronutrient for overcoming iron deficiency chlorosis in soybeans. Exclusively distributed by CHS Agronomy, Soygreen is an iron (Fe) formula developed for soybeans and other crops suffering from iron deficiency chlorosis. It has the purest and highest concentration of ortho-ortho EDDHA chelate compared to other premium micronutrient products. This chelating agent keeps the iron (Fe) soluble for uptake and even makes other nutrients in the soil available to the plant.
Soygreen is available in three different formulations to better fit your application needs. A dry water-soluble powder that is easy to mix and apply, a convenient liquid solution for ease and convenience, and a granular blend that is designed for the air seeder market.
Soygreen® is a powder iron product chelated with Levesol's ortho-ortho EDDHA, making it the most effective and proven IDC product on the market.
Soygreen® AST is a liquid ortho-ortho EDDHA chelated iron solution designed to minimize leaching and allow the product to be available in the root zone longer.
Soygreen® Granular 2.4 is a superior granular iron product containing Levesol’s ortho-ortho EDDHA chelate and is designed for air seeder application.
IDC does not have to be a death sentence for soybeans. With a keen eye on potential warning signs and preventative measures in place, such as utilizing Soygreen®, growers can mellow the yellow in their crop or avoid IDC altogether.
