Determining the profitability of your cover crop may not be as crystal clear as calculating your net profits. Some benefits start small and increase each year the practice is continued. Cover crops offer benefits across farm management, so consider the following improvements outlined by Dr. Rob Myers in How to Measure Cover Crop Success when evaluating the success of your cover crop:
Cover Crop Costs & Benefits Calculators
There are several tools available to help determine and calculate cover crop costs and profitability. Each calculator is designed as a downloadable and fillable Microsoft Excel document that will help you calculate the profitability of different cover crops for your practice. The economics simulator is a web-based tool that comes with a detailed user guide.
Iowa Learning Farms created the Cover Crop Cost and Cover Crop Seeding Rate Calculators, Iowa State University Extension and Outreach created the Economics of Cover Crops Costs & Benefits tool, and Iowa Soybean Association created the Cover Crop Economic Simulator.
The Iowa Agriculture Alliance’s Iowa Cost Share Comparison page outlines helpful Cover Crop cost share program information for farmers to easily access. Their charts compare the services each program has to offer. Visit their webpage to download the charts to use their clickable weblinks to navigate the information with a breeze.
Shared here is IAWA’s chart showing which incentives stack.
IAWA also provides an Interactive Cost Share Comparison tool that allows producers to add and compare how different incentive stack and to help producers decide which Cost Share Programs to enroll in to get the maximum benefits for their practice.
Cover Crops will pay for themselves best when being used to meet multiple needs.
From the SARE Technical Bulletin, some ways to gain more profitability out of Cover Crops include:
While the District can help you apply for State cost share funds, there are opportunities for stackable funding through other privately organized cost share programs.
Some private cost share opportunities we are aware of include but are not limited to:
There are Federal Funding opportunities also available for cover crops that may not be stackable with State Cost Share, but may be an attractive alternative:

Peer group farmers are a valuable resource for anyone looking to start conservation projects or adopt regenerative farming practices. These experienced farmers have already implemented various conservation strategies on their own farms and can offer practical insights, advice, and support. By joining a peer group, you gain access to a network of individuals who understand the challenges and rewards of sustainable farming. They can provide guidance on best practices, share lessons learned, and even offer hands-on assistance. Engaging with peer group farmers can significantly ease the transition to new farming methods, helping you to avoid common pitfalls and achieve success more quickly. Their collective experience and willingness to share knowledge make them an indispensable part of the farming community.
