If Cover Crops are so Great, Why Aren’t More being Planted?

By Joe Christner, Water Quality Technician, Holmes SWCD

In my last article, Planning for Cover Crops, I wrote about the 101% increase in cover crop acres in Ohio over the past five years. While this is great progress, we still have a long way to go, as only about 7-10% of Ohio’s crop land is being seeded to cover crops. I found this somewhat surprising considering the many benefits of cover crops and the increased focus on water quality and soil health. Some of those benefits include:

· Prevent erosion

· Reduce soil compaction

· Improve rainfall infiltration (especially this year)

· Scavenge nutrients and provide nitrogen (legumes)

· Build soil organic matter

· Control weeds

· Encourage pollinators and beneficial insects

· Economic returns

So why aren’t farmers planting more acres to cover crops? As I thought about it, I was almost sure it had to do with the last benefit on the list: economic returns. This is because a simple, one-year budget analysis of cover crops, one that just compares the cost of seed and seeding to the impact on the next crop yield, may indeed show a loss. When evaluating average fields in average weather conditions, it can take three or more years for cover crops to pay off if no incentive payments are obtained and no special circumstances exist.

Used in a cover crop mix the rapidly growing daikon radish can, reduce erosion, sequester nutrients and alleviate soil compaction.

When it comes to making management decisions such as planting a new crop or buying equipment, farmers are running a business and the bottom line is always a huge consideration. If the idea doesn’t work out on paper, either by cutting costs or raising revenue, then it likely won’t happen.

Determining the economic impact of planting a cover crop is not as simple as one-year cost and return analysis. There are several factors to consider such as: How do I determine the dollar value of all these cover crop benefits in my operation? What does it really cost to include cover crops in my cropping system? How long does it take before cover crops start to pay? In spite of all the benefits, what is the bottom line? Last week our staff read a very informative technical bulletin from SARE (Sustainable Agriculture Research & Education) that does a great job of answering those questions based on research and farmer experience. The bulletin is titled: Cover Crop Economics, Opportunities to Improve your Bottom Line in Row Crops. The link to this bulletin is


It is rather long, but it is great resource to calculate the bottom line of cover crops in your operation, and the last page has a good summary. It explains the factors involved in economic returns from cover crops and assigns dollar values to those factors. It will help you make cover crop management decisions based on the bottom line for your farm.


This bulletin describes seven situations in which the profitability of cover crops can be accelerated.

Cover crops can pay their way more quickly when:

1. Herbicide-resistant weeds are a problem

2. Cover crops are grazed or harvested

3. Soil compaction is an issue

4. Cover crops are used to speed up and ease the transition to no-till

5. Excess soil moisture in the spring (like this spring)

6. Fertilizer costs are high, or manure nutrients need to be sequestered

7. Incentive payments are received for using cover crops

The farmers profiled in this bulletin have found that cover crops are most profitable when they provide benefits in multiple areas such as compaction and weeds.

Most farmers who have long-term experience with cover crops and who carefully keep their books have discovered that cover crops do in fact pay. These farmers usually look at cover crops from the broad, holistic standpoint of how they will improve the efficiency and resiliency of the entire farm over time.

Cover cropped fields can see a significant bump, and retention of soil organic material.

One of the most-often-cited economic benefits of cover crops by experienced users is their impact on the resiliency of the cropping system. Farmers are finding that by helping to minimize drought-related yield losses or sometimes allow­ing earlier planting in a wet spring, cover crops serve as a type of crop insurance. As with ordinary crop insurance, the pre­mium you pay for cover crops will pay off big in some years, but not every year. “Look at cover crops as an investment rather than a cost,” advises Justin Zahradka, who farms 900 acres in North Dakota and has been planting cover crops since 2011.

The deadline to sign up for potential cost share on cover crops through a Muskingum Watershed Conservancy District program is July 9. Participants may choose to participate in the aerial application program or drill/broadcast by a planting deadline date.
