Profiling Iowa's Conservation Successes in 2012 & 2013
Rogers Successfully No-tills River Bottoms
By erasing three words from his vocabulary – can’t, won’t and don’t – Woodbury County farmer Randy Rogers has effectively done what most local farmers have been unable or unwilling to do – successfully strip-till corn and no-till soybeans on the Missouri River Bottoms.
MRBI Conservation Practices Improving Soil Conditions, Too
Eagle Grove farmer Tim Smith’s participation in a USDA conservation program designed to reduce nutrient and sediment loading into local waterways – and eventually the Mississippi River – is also improving the health of his soils using fewer disturbing activities such as deep tillage, over-fertilizing, and keeping living roots in the ground longer through cover crops.
The number of cover crop acres has increased dramatically over the past five years in Iowa – from less than 10,000 acres in 2009 to about 300,000 acres this fall. One Iowa farmer who is helping to increase that number is Joe Kriegel who farms and grows cover crops on more than 2,000 acres in Poweshiek County with his three sons, Patrick, Nicholas, and Jared.
Many attribute Iowa’s agricultural soil erosion and water quality issues to row crop production. However, open – or continuous – grazing can also lead to gullies and cattle trails that can cause severe erosion and sediment runoff, as well as reduce forage tonnage produced on Iowa pastures.
Growing strong crop yields is important to farmer Don Elsbernd, but the National Corn Growers Association member is more interested in protecting his natural resources and improving profit margins through soil conservation practices.
Charter Oak farmer Craig Brodersen chose the right year to start using cover crops. He aerial-applied winter hardy cereal rye for the first time last fall into 400 corn acres, and it helped dramatically reduce erosion on much of his newly planted soybean ground this spring.
A unique wetland north of Charles City is helping to filter out upland sediment and other chemicals from ag runoff flowing into the Little Cedar River, and fulfilling a family’s goals by preserving the land and providing a wildlife haven on their farm.
Premier Iowa Hay Grower Discovers Soil Health with No-Till Alfalfa
Adair County farmer Dennis Lundy began no-tilling alfalfa hay for the first time five years ago to prevent soil erosion on his rolling, highly erosive Shelby soils. Now, he is not only reducing soil erosion but also improving his soil health and achieving better alfalfa stands.
