How Fast Do Corn Roots Grow? ISU is Taking a Look June 22, 2017

Have you ever wondered how fast corn roots grow? Colleagues at Iowa State University have a number: more than 2 ¾ inches per leaf stage. That's about one inch per day!  Soil cores were taken in the row and in the center between two rows. They used the cores to identify the presence of roots (depth and lateral growth).

Nebraska Researchers on Multi-State Team to Study Psychology of Water Use May 17, 2017

Six University of Nebraska researchers will join colleagues at Penn State University, Arizona State University and the U.S. Department of Agriculture’s Agricultural Research Service (USDA/ARS) to develop a model for engaging communities and stakeholders around issues of sustainable water use. The project will help us better understand how farmers and other water users get information and make decisions about water usage in agriculture.

Multi-State Research Looks at Means for Optimizing Inputs to Enhance Profits April 21, 2017

Six researchers at the University of Nebraska-Lincoln are working on the USDA-NIFA-funded Data Intensive Farm Management (DIFM) project. DIFM is based at the University of Illinois, and also involves the Universities of Kentucky, Massachusetts, Maryland, and Illinois State. The overarching goal of the project is to collect production data after conducting large-scale, on-farm randomized input use field trials, and then using the information to inform growers of optimal input use practices to enhance their profits.

Proposed changes in top private agricultural chemical and seed research ownership

Mergers and Competition in Seed and Agricultural Chemical Markets April 10, 2017

Under recent merger proposals, the six global firms that dominate private agricultural chemical and seed research and production would be reduced to four. In the most recent edition of Amber Waves, a USDA Economic Research Service site, economic researchers examine possible effects of these changes in seed and ag chemical markets, including on prices and innovation. The “Big Six” — BASF, Bayer, Dow Chemical, DuPont, Monsanto, and Syngenta — emerged in the 1990s and early 2000s, arising from mergers among large chemical, pharmaceutical, and seed companies as well as from their acquisitions of many smaller seed and biotechnology companies.
