DuPont, University of Missouri and USDA-ARS Collaborate on Soil Mapping

Aim to enhance sustainable crop production with field and crop modeling

The public-private effort aims to enhance sustainable crop production through field and crop modeling that targets the specific soil, climatic, water-shed and production conditions within producers' fields with real-time information. The three-year exclusive agreement among DuPont Pioneer - the global seed and advanced plant genetics business of DuPont - the University of Missouri and USDA-ARS will bring together the respective strengths of each party in precision agriculture sensors and soil mapping, including the characterization of soil types, topography and water-sheds. Through a unique computerized process offered by DuPont that uses the latest high resolution technology, the collaboration will result in more accurate soil mapping units than ever seen before.

Higher-resolution soil information will enable improved placement and management of crop inputs such as nitrogen fertilizer. The enhanced soil maps build on public soil survey data and will support Decision Agriculture Services provided by DuPont to help crop producers make timely decisions to more sustainably improve yields and per-acre income. Soil analysis procedures will better identify unique land areas called Environmental Response Units (ERUs). These ERUs can then be used to develop a variety of management zones. A trusted Pioneer advisor will assist growers in tailoring input and management plans to fit their goals of the best possible per-acre yield. This University of Missouri and USDA-ARS collaboration will provide vastly improved soil mapping resolution. "DuPont Pioneer has long been dedicated to providing our customers with products and services that bring the greatest value to each acre through sustainable field management," said Paul E. Schickler, president, DuPont Pioneer. "This public-private collaboration with Missouri and USDA-ARS takes that effort to a higher level, helping growers increase yields while being better stewards of the environment. We are building these tools in the US, but intend to expand Decision Services offerings into other international markets over time." "Management decisions strongly depend on how crops respond to the soil and landscape," said Brent Myers, Ph.D., agronomist, University of Missouri. "Public soil maps are very valuable, but we can now track differences in fields at a much higher resolution than previously available. ERUs identify smaller areas within fields that can be similarly managed. This collaboration provides opportunities for connecting innovative soil and landscape science with decision-making for millions of acres in the US." By using high resolution elevation data and landscape watershed information, producers can better determine water and nitrogen movement on the section and county levels. Together with soil and productivity information, growers can more accurately plan, place and manage nitrogen applications on a real-time basis.
