Just like people, plants need nutrients to help them grow. Antonio Mallarino, professor of agronomy, has put together a team of scientists from across the Midwest to better understand how micronutrients aid growth and development of soybeans.
“Micronutrients are nutrients that are essential for crops but are only needed in very small amounts,” says Mallarino. “Those most commonly thought about by farmers are boron, copper, iron, manganese, molybdenum and zinc.”
Mallarino led a team of researchers and extension specialists from five universities in reviewing micronutrient research on soybeans in the North Central region. This included over 200 field trials conducted in five states since 2012.
Micronutrients are needed in very small quantities by plants, but are essential for their growth and production. A search for understanding how micronutrients can be better managed in the Midwest’s soybean fields has led to new research and a regional publication on the topic.
This research and general management guidelines are summarized in the publication “Micronutrients for Soybean Production in the North Central Region” (CROP 3135) and is available through the Iowa State University Extension Store. Antonio Mallarino, professor and extension specialist in agronomy at Iowa State University, led a team of researchers and fertility extension specialists from five universities across the Midwest who worked on the project.
