• Cover crops and water• Status of cover crop adoption• Strategies to increase adoption• Examples of ag and water partnerships from Clean Water

It costs $4.8 billion annually to remove nitrates from drinking water, $1.7 billion from ag runoff.

How do cover crops improve water quality?

Reduce sediment runoff– N and P loading

Reduce nitrate leaching

Reduce need for fertilizer, chemical inputs

And by how much…?

Every 1% increase in soil organic matter can increase soil water storage by 16,000 gallons – NCAT

Winter rye cover reduced nitrate loss in tile drainage system by 43% - Kaspar, 2014

Cover crops reduce phosphorus pollution by 50% - Iowa Nutrient Reduction Strategy

5

Goal = 20 million acres by 2020

10.3 million acres of cover crops = 2.6% of cropland

911k, 3%

596K, 4.7%

328K, 23%

70K, 16%

Why don’t more farmers use cover crops?

Fact: Change takes time and costs moneyMyth: Cover crops won’t work in my region…Myth: Cover crops won’t work in my cropping system…Fact: Cover crops can work almost anywhere with proper

management, but there is a learning curve.

Roadmap to Increased Adoption

• Support the champions• Address policy barriers• Advance cover crop

research• Improve technology and

equipment availability• Develop a unified and

compelling message

County– Goal: 3100 lbs of P – Cost $40/lb

Wisconsin: 553K, 6%Clean Lakes Alliance

Miami River Conservancy District, Ohio

Nutrient trading program– EPA and USDA funding

Cost of POTW upgrades = $422 million

Conservation practices = $50 million– 572 tons of nutrient

reductions – $0.36-2.00/lb of P

Ohio: 357K, 3% Daniel Johnson Jr., flickr

Iowa Nutrient Reduction Strategy

Iowa: 379K, 1.4%

Practice potential– 28% less N– 50% less P

Increase cover crops to 60-95% of acres
