Enhancing Water Productivity|
& Resilience.

The WCS-FARM project focuses on Water Productivity, Carbon, Field-Scale Agricultural Research Multi-Crop Systems. This initiative integrates multi-crop systems through field-scale research, aiming to enhance water use efficiency, carbon sequestration and profitability through advanced management practices, promoting resilience to the cropping systems in the US.

WCS-FARM — Water, Carbon, Sustainability, Field-Scale, Agricultural, Research, Multi-Crop Systems

A large-scale, multi-institutional project

Collaboration across the U.S. Corn Belt & Great Plains

With collaboration from universities and organizations spanning the U.S. Corn Belt and Great Plains, our research investigates how agricultural management influences soil microbial communities and ecosystem functions. FFAR, Kansas State University and Bayer Crop Science — together with Iowa State University, the University of Kansas and partner institutions — have driven this transformative initiative.

Project goals & research priorities

Building productive, resilient agroecosystems

The project's objectives align with critical aspects of agroecosystem productivity and resiliency — addressing knowledge gaps and developing tools and technologies for site-specific decision-making that connect farmers and scientists to co-create durable solutions.

1

Long-term productivity

Determine the long-term impact of multi-management factors on productivity and sustainability.

2

Soil microbes & carbon

Characterize how management practices affect soil microbial diversity and activity, and their link to soil carbon storage and greenhouse-gas emissions.

3

Process-based modeling

Use process-based modeling to predict and explain cropping-system productivity and soil-carbon contributions.

Rotation intensity Nitrogen application Tillage vs. no-tillage Cover crops

Innovative approaches & technologies

Sensing the field at high resolution

To achieve its objectives, WCS-FARM employs high-resolution soil sensors, water-monitoring wells, carbon modeling and detailed profitability analysis. The research explores crop-management practices — rotation intensity, nitrogen application, tillage versus no-tillage, and cover crops — to refine the knowledge, technology and practices that address water and environmental challenges.
