Conservation Chat: We must clean up our water sources voluntarily

Ben&Amy Johnson2

Ben Johnson and his wife Amy.

This month, host Jacqueline Comito has a conversation with a farmer in northeast Iowa. Ben Johnson is a sixth generation farmer that purchased his first farm with his brother Andy when he was a sophomore at Iowa State University. Conservation saves him one of his most valued resources on the farm: time.

Johnson takes part in our Conservation Learning Lab program with a small scale watershed and CREP wetland on a neighbors property. He and his family began using cover crops in 2013, a year that had a terribly wet spring. They had 200-300 acres that were too wet to plant and didn’t want them to sit bare all year so they took an old seeder and ran oats and radishes that August. He noticed an improvement in the soil tilth right away and in the beans produced that fall. 2013 was also the year that they introduced strip-tilling, increasing water absorption and yield in those areas.

Other conservation methods Johnson employs are buffer strips, prairie CRP, pollinator habitats, field windbreaks and a pheasant safe program. Johnson says, “The easiest place for somebody to start is no-tilling their beans. They don’t really seem to respond to tillage and it’s such a labor and money eater. That’s the biggest reason we switched. The most precious resource on my farm is time.”

“I hope my kids can be the seventh generation (to farm) so it means a lot to me to leave the land in as good or better shape than it was when I started,” that means the soil needs to be productive and the water needs to run clear “I want all my black soil still on top of my hills and not at the bottom of all of them, not in my road ditches and not in the Cedar River.”

Listen to this Episode of Conservation Chat to learn about the numerous benefits of strip-till, no-till and cover crops and how easy it can be to get started! You can subscribe to the podcast for future episodes as well.

Iowa’s Future Begins with Healthy Soils

Today’s guest post is by Marty Adkins, Assistant State Conservationist for Iowa Natural Resources Conservation Service (NRCS), a member of the Iowa Learning Farms Steering Committee.

The quality of Iowa’s soils make this a unique place. How we manage Iowa’s agricultural soils affects just about everything else here. From increasing wildlife to improved water quality to sustainable economic development, our future begins with healthy soils.

Janke-PheasantWildlife – Over 97% of Iowa’s land is privately owned, and a vast majority is a part of farms. Most Iowa wildlife spends some or all of their lives on farms.

The same practices that are good for Iowa soils – no-till farming, cover crops, buffer strips, diverse native plant seeded areas, waterways, diverse crop rotations, well-managed pastures – are good for wildlife. The practices provide cover, food and travel corridors. They protect water sources on which wildlife depends. Practices that protect and build soils are good for wildlife too.

Water Quality – Water bodies reflect the condition of their watersheds. Eroding fields deliver sediment and nutrients to streams and lakes. Soils protected from erosion keep that soil and associated nutrients in fields where they belong.

Fields protected by cover crops or other vegetation growing throughout the growing season retain nutrients in the root zone that would otherwise find their way into streams or ground water. Practices that protect and build soils are good for water quality

Economic Development – Over one-third of the largest 100 food manufacturers have Iowa operations. These companies are located in Iowa because the commodities they depend on are produced here.

HC-SoilStatistics from 2014 showed that agriculture and related industries contributed $31.6 billion to the Iowa economy and was responsible for 122,764 jobs. They also showed that 37 of Iowa’s counties derived at least one half of their economic output from agriculture and related industries.

The foundation of all of this economic activity, now and into the future, is Iowa’s productive soil.

No matter what issue you care about, you need to be interested in protecting and building Iowa’s soils.

Reducing Nutrient Losses While Building Iowa’s Soils and Economy

Today’s guest post is by Marty Adkins, Assistant State Conservationist for Iowa Natural Resources Conservation Service (NRCS), a member of the Iowa Learning Farms Steering Committee.

Iowa’s soils are globally precious and unique. These soils are the cornerstone of a vibrant and productive farming sector and make Iowa’s overall economy strong.  Protecting and building the productive capacity of Iowa’s soils is essential to Iowa’s future.  Happily, many of the same practices that help protect and build soils also have a positive impact on water quality.  This is especially true of cover crops, crop rotations that include small grains and forages, and no-tillage and strip-tillage planting.

Marty Adkins and his other passion in life; playing the ukulele.

The widespread adoption of cover crops will require increased availability of seed and seeding equipment.  There are new business opportunities related to the growing, cleaning, transportation, sales and custom planting of cover crop seed.  Iowa’s farm machinery industry can continue to design, build, sell and service equipment needed for cover crop seeding and management, and increased adoption of no-till and strip-till.

There are other farm business opportunities to consider when it comes to conservation farming practices.  Cover crops and extended rotations could provide more grazing for more livestock in more places, with more small-town businesses selling all needed goods and services to livestock farms.

In addition to increased economic activity in the farm and industrial sectors, there are other economic benefits to be gained from conservation practices.  An Iowa countryside that is green nearly all year-round, with the land covered and protected, would be a more attractive landscape for Iowa residents, and could attract visitors and new entrepreneurs.

Economic research shows that cleaner streams and lakes result in increased recreational opportunities (swimming, canoeing, boating, and fishing) and more tourism to towns and cities associated with these amenities.  More dollars stay in Iowa when Iowans vacation and recreate within the state.

The environmental benefits associated with better soil management are well documented.  But improved soil management can also contribute to Iowa’s economic well-being, now and long into the future.

Starting the Conservation Conversation

Land rental relationships can vary, but many face similar challenges of discussing new conservation practices with your tenant or landlord.  To help begin the conversation, Iowa Learning Farms created a new publication series with talking points and relevant research findings about a variety of conservation practices.

“A large number of Iowa cropland acres are rented every year; nearly 50% according to recent surveys. These rented acres are greatly influenced by the tenant who farms them,” stated Mark Licht, Iowa State University assistant professor of agronomy and Iowa Learning Farms advisor, who cultivated the idea of the series.

“Landowners are integral in the decision-making process: from leasing structure and understanding farming practices, to being considerate of practice costs and profitability.  With emphasis being placed on nutrient loss reduction and practices ranging from in-field to land use changes, it’s imperative for landowners and tenants to have conversations about reaching production, profitability, and environmental goals,” said Licht. “These conversations can lead to improvements of soil health and water quality, along with meeting productivity and profitability goals.”

Examples of leasing structures that can be used when adding cover crops included in the series.

As land is passed from one generation to another, or is sold, it can lead to uncertainty for tenants and landowners alike.

strip tillage benefits.png“We developed this series in response to questions we heard from landowners. They wanted to understand how conservation practices such as strip-tillage and cover crops would affect both their land and the tenant’s bottom line before asking them to add these practices to their management plans,” explained Jacqueline Comito, Iowa Learning Farms director.

“While the name of the series is ‘Talking to Your Tenant,’ the reverse is also true. We think tenants will find the series also helpful as they educate their landowners on implementing these important practices,” adds Comito.

The series addresses in-field practices like cover crops, no-tillage and strip-tillage, and edge-of-field practices such as denitrifying bioreactors and wetlands.

If you have ideas for future topics for this series, contact Liz Juchems at ilf@iastate.edu or call 515-294-5429.  The four-part series, along with other print and video resources, are available online. Copies will also be available at field days and workshops, or mailed to you upon request.

Real Cost Savings with Strip Till + No-Till

One of the common themes we hear from our farmer partners with Iowa Learning Farms is that you do your best thinking and decision-making when prices are low and margins are tight.

Significant cost savings in your farming operation can be realized in the form of reduced tillage. Every pass you make across the field with a tillage tool costs money in terms of labor, fuel, and wear-and-tear on equipment. A recent article in Successful Farming, titled Slash Tillage: Reducing the amount of tillage you do can cut costs, boost yields, and benefit the environment, highlights several farmers from across the Corn Belt who have recently adopted no-till or strip-till into their farming practices and yielded some very positive benefits.

One thing that really stood out to me was the cost savings with strip till. Farmer Dave Delhotal of West Brooklyn, Illinois, noted:

A few additional highlights from the story and words of wisdom:

If you’re thinking of switching to NO-TILL, start with soybeans. Mark Hanna, ISU Agricultural Engineer, notes that tilling ahead of soybeans can be difficult to justify:

No-tilling in corn can be more challenging, admits Hanna. Additional management considerations are a must, which can include installing tiles, adjusting combine settings, changing planter setup, and making shifts in weed control and fertilizer application.

Looking for a middle ground?

STRIP TILL provides the best of both worlds: a 6-12” strip of full tillage within the row to give each seed an ideal seedbed and no-till across the rest of the field. Producers have noted many benefits:

Nutrient management and strip till can also work very well in concert.

Travis Harrison of Wayne, Ohio, uses yield data and soil test results to determine his nutrient application rates and this in integrated right into his strip till operation:

Farmer Tim Smith on The Chat

Farmer Tim Smith took time to sit down with Jacqueline Comito to discuss his whole farm approach to soil health and water quality in this engaging episode of Conservation Chat.

aerial 9-29-2014

Cover crops showing off their true colors in Tim’s soybean field.

Tim started farming in his early 20’s and had always thought that he was doing what was necessary towards protecting his soil and nearby water bodies by minimizing his tillage passes and by installing filter strips along the stream bank. It wasn’t until he tested his tile lines for nitrates that he made a farm-changing discovery. “Even though I was doing the best that I could, it was still not solving the problem, and I was part of the problem.” Tim said.

This realization led Tim to add a suite of conservation practices on his 800-acre corn and soybean operation.

Click here to find out what else Tim has done on his farm, his future plans, and how he successfully reduced his nitrate levels to below the 10 parts per million EPA guideline for safe drinking water.
