What Drives Financial Success in Cover Cropping? New Insights From a Three-Year Analysis of Farm Financial Data

By Mai Lan Hoang

Cover crops offer many benefits to farms and local communities, including building soil health and improving water quality. However, for farmers to adopt cover crops at scale, the economic return must be clear and measurable. Farmers need reliable data on how cover crops impact their bottom line, especially as they currently face significant economic uncertainty.

To meet this critical need, Environmental Defense Fund and partners have released a report that provides farmers with clear, reliable data on the financial impacts of cover crops gathered from real Minnesota farm records spanning several growing seasons. For the first time, the report compiles multi-year financial outcomes to provide a comprehensive analysis of cover crop costs, returns and their effects on primary crops from 2022 to 2024.

These findings provide valuable insights on how farmers, their partners and conservation programs can improve the financial viability of cover crop adoption. Here are the key takeaways:

1. Strong cost management sets profitable fields apart.

In our analysis, the most profitable cover crop fields consistently had lower per-acre costs compared to low-profit fields in our analysis. The total direct cost of growing cover crops for a typical high-profit field was only about half the cost of low-profit fields.

The study found that cover crop seeds and machinery repairs were the key expenses driving the cost differences between high- and low-profit fields. The more profitable fields used cheaper cover crop seeds and had fewer machinery repairs.

2. Cost-share programs play an important role, but gaps remain.

Cost-share programs – including state, federal and private sector funds that offset a portion of farmers’ costs to plant cover crops – play a critical role in supporting profitable cover crop adoption. The most profitable cover crop fields in the analysis consistently used cost-share payments to offset the financial costs of using cover crops.

For producers who had access, cost-share payments covered more than half (54% on average) of total direct cover crop costs. Unfortunately, only 27% of farmers in our study received these payments since many of these programs only support farmers in the first few years of implementing conservation practices like cover cropping. This demonstrates a significant gap and underscores the ongoing need for broader access to cost-share support to help more farmers adopt cover crops successfully.

3. Generating revenue from cover crops drives financial profitability.

Cover crops are typically planted in the fall to reduce soil erosion, retain soil moisture and provide soil nutrients, among other benefits. In some cases, they can also generate revenue when harvested for seed sales or animal feed.

The three-year analysis found that rye silage, when harvested for livestock feed, was the only cover crop to generate a positive return for participating farmers – not including its financial impact on the following cash crop. Other cover crop types, including rye and cover crop mixes, did not produce direct revenue to offset their costs.
