Deadline to Seed Cereal Rye Cover Crop Extended Additional 2 Weeks Statewide


DES MOINES, IOWA, Oct. 26, 2017— Iowa Deputy Secretary of Agriculture Mike Naig and State Conservationist Kurt Simon with USDA’s Natural Resources Conservation Service (NRCS) announced that farmers participating in state cost-share and most federal financial assistance programs now have an additional two weeks to plant their winter hardy cereal rye cover crop and still qualify for assistance.

The seeding date is extended following the announcement that only 61 percent of Iowa’s soybeans and 23 percent of corn were harvested as of Sunday, Oct. 22. “The crop report indicated both corn and soybean harvests are behind the five-year average,” said Naig. “Extending the deadline an additional two weeks will allow additional farmers to get a cereal rye cover crop planted, benefitting water quality.”

“Late seeded cereal rye provided adequate spring growth for erosion control in the past when allowed to grow to at least eight inches tall before termination,” said Simon.

The revised cover crop seeding dates for cereal rye are:

Zone 1 (Northern Iowa) Nov. 4 – 18

Zone 2 (Central Iowa) Nov. 11 – 25

Zone 3 (Southern Iowa) Nov. 19 – Dec. 3

Guidance from Iowa State University confirmed cover crops planted within these dates still have the potential to provide a substantial reduction in nutrient losses and soil erosion.

 The following applies to cover crops planted during the extension period:

Seed cereal rye as soon as possible after harvest of the principal crop.

The cover crop will be no-till drilled into crop residue.

Allow the cover crop to grow until at least 8 inches before spring termination.

It is recommended the seeding rate of cereal rye be increased to 75 pounds Pure Live Seed (PLS) per acre to adjust for reduced tillering.

The extension does not apply to all federal programs. Contact your local NRCS office if you have questions.

 Farmers approved for cost-share assistance who are still unable to plant cover crops should contact their local NRCS office.

Conservation Compliance Change Requires Treating Ephemeral Gully Erosion on Highly Erodible Land

DES MOINES, IA – Harvest is the season when many farmers discover areas of ephemeral gully erosion which had been hidden by plant canopies. Typically, many farmers smooth those areas with a tillage pass soon after harvest or in the spring before planting.

However, Iowa famers who participate in USDA programs will now be required to provide additional control of ephemeral gully erosion on their highly erodible fields, State Conservationist Kurt Simon said.

Ephemeral gullies are the smaller ditches in fields that farmers often smooth with a disc before planting crops. Simon, who heads the USDA’s Natural Resources Conservation Service (NRCS) in Iowa, said that previously, compliance was not an issue when fields contained only small areas of ephemeral gully erosion.

This change is in response to a recent Office of Inspector General (OIG) report comparing compliance review procedures in several states. OIG recommended modifications to NRCS’ compliance review procedures to provide more consistency across the nation. Thus, Iowa NRCS has made compliance review procedure adjustments that might impact farmers.

Since the passage of the 1985 Farm Bill, farmers have been required to control erosion on fields that are classified as highly erodible. Each spring, NRCS conducts compliance reviews on a random selection of highly erodible fields to determine if erosion has been adequately controlled.

“Affected farmers will need to consider installing additional conservation practices to better control ephemeral gully erosion,” Simon said.

A non-compliance ruling can affect benefits that farmers receive from USDA agencies in a number of ways—from Conservation Reserve Program payments to Price Loss Coverage.

Simon said NRCS employees will work closely with farmers to help them meet erosion-control requirements. He added that farmers may not be expected to complete these changes immediately. If erosion control issues are identified during compliance reviews, producers may be given time to make adjustments and install needed conservation practices. Typical practices used to control ephemeral gullies include no-till farming, cover crops, grassed waterways, and terraces.

He said Iowa NRCS offers financial assistance to help farmers install or implement conservation practices across the state. Landowners can sign up for voluntary Farm Bill conservation programs on a continual basis.

Simon stressed the importance for farmers to meet these erosion control requirements so they will remain eligible for Farm Bill program benefits, including federal crop insurance premium subsidies. NRCS staff are available to help farmers identify ephemeral erosion in their fields or where it may occur, and then assist them with applying the conservation practices that best fit their farming operations.
