CALS Research Advances

Researchers in the College of Agriculture and Life Sciences at Iowa State University’s Iowa Agriculture and Home Economics Experiment Station advance knowledge through basic science and its application in the fields of agronomy, animal science, food safety, ecology, plant pathology and the social sciences, building on 130 years of leadership. The Experiment Station's work represents 15 departments and 32 centers, institutes and initiatives, and also supports research in other ISU colleges and in cooperation with scientists in other states and countries.

CALS Research Strengths

CALS ranks first out of 60 agricultural colleges for the number of faculty with federal research grants and third for the total number of federal grants, according to Academic Analytics comparisons (Feb 1, 2020). It also ranked second nationally for the number of faculty publishing findings in scientific journals.

Nearly $56 million in external funding was received by CALS/Agricultural Experiment Station-supported faculty and staff in the fiscal year ending June 30, 2020. Nearly 65 percent of the funding came from federal agencies. Over the past five years, CALS has brought in $275 million in external funding, averaging more than $55 million per year. These discoveries and inventions frequently are patented and licensed for development into products and services:

  • Research by CALS faculty and staff account for 80 percent of Iowa State University's 377 active technology licensing and option agreements (FY2020).
  • CALS and the Experiment Station received the largest share of royalty income at Iowa State for the last five fiscal years.
  • Nine of the top 20 income-producing technologies at Iowa State came from research in CALS and the Experiment Station in the last two years. 

How our Research is Funded


Research Highlights

Steven Hall in labNew study identifies climate change effects of poorly drained soils
A new study reported in the Proceedings of the National Academy of Sciences found that poorly drained agricultural soils emit enough of the greenhouse gas nitrous oxide that the resulting climate change effects could far exceed the benefits of using the same soils as a means of sequestering carbon. The Iowa State research team was led by Steven Hall, associate professor of ecology, evolution and organismal biology. More.

The Foundation for Food & Agriculture Research has awarded a $2,044,214 grant to Iowa State University to evaluate how maize breeding, field management and environment affect sustainable corn production. Led by Sotirios Archontoulis, associate professor of agronomy, the project will examine corn hybrid characteristics at an unprecedented scale to analyze yield trends in the U.S. Corn Belt. The project represents a $4,089,857 total investment, with additional funding from Iowa State, Bayer Crop Science, the Leopold Center for Sustainable Agriculture and others. More.

A diverse team of 18 scientists led by D. Raj Raman, Morrill Professor of Agricultural and Biosystems Engineering at Iowa State, received a five-year, $10 million grant from the U.S. Department of Agriculture’s National Institute of Food and Agriculture to study the potential environmental benefits afforded by perennial groundcovers, which grow every year without having to be planted or harvested, between rows of cash crops.

CALS agronomists help lead COALESCE 
Iowa State University faculty in mechanical engineering and agronomy are part of the research team on the COALESCE – COntext Aware LEarning for Sustainable CybEr-agricultural systems, project, which is receiving a five-year $7 million Cyber-Physical Systems Award from the National Science Foundation and the U.S. Department of Agriculture's National Institute of Food and Agriculture.
