General Guidelines for Winter Manure Applications

Mon, 26 Jan 2026 20:56:56 GMT

Winter weather arrived early here in the Midwest. Not only did it start early, but we also experienced large fluctuations in temperature and conditions. We saw subzero temperatures and accumulating snow before Thanksgiving, then temperatures in the 60s the week of Christmas. Winter weather can make manure applications very tricky. Each state and local government has regulations for winter manure application. General guidelines can help prevent runoff and nutrient loss, and protect water sources.

Create a Buffer

Most regulations on manure application aim to protect natural water sources. One simple way to help prevent runoff into streams, rivers, and lakes is to create barriers. Maintaining a buffer around surface water, tile inlets, and waterways has been shown to significantly reduce runoff. Research indicates that a 200-foot buffer can decrease nutrient runoff by 80% to 90%. Overall, runoff volume can be reduced by 35% to 90%.

Consider Crop or Residue Cover

Spreading on bare ground can lead to increased runoff. Using crop cover, either with cover crops or crop residue from fall harvest, can significantly reduce runoff. Crop residues or the presence of cover crops as the surface begins to thaw give manure nutrients something to adhere to. Research shows that cover crops can reduce runoff by 40% to 100%, depending on field, crop, and environmental conditions. Fields with less than 25% crop residue tend to have a higher risk of runoff. Low-yielding soybeans and fields used for corn silage often have less than 25% crop cover during winter months. Spreading on fields with cover crops, hay, or pastures would allow for more nutrient absorption.

Make Good Land Choices

Two major factors of land can significantly influence runoff and nutrient loss. The first is the slope of the ground. Avoid applying manure where the ground slopes exceed 15%. Slopes of less than 5% are ideal. The second consideration should be soil type and water-holding capacity. Soil with higher water-holding capacity will result in less runoff. Fine sandy, silty clay, and silt loam soils tend to have the best water retention.

Check the Forecast

If spreading on snow-covered or frozen ground is necessary, be aware of how weather impacts nutrient absorption. Avoid spreading manure before snowmelt or rainfall. Adding moisture to frozen ground will increase nutrient loss. The rate of snowmelt should also be considered. Slower snowmelts allow for increased soil absorption of manure nutrients. Therefore, checking future temperature and weather conditions is important to prevent runoff.

Winter manure spreading is often not recommended because it can lead to higher nutrient losses and harm water quality. Some states have even banned winter spreading. However, if storage capacity is limited and manure spreading is necessary, the guidelines above can help reduce nutrient loss.

Digging into Soil Health

Tue, 03 Dec 2024 22:14:48 GMT

One hundred years after the Dust Bowl blew away topsoil from nearly 200 million acres of American farmland, farmers and ranchers are slowly entering into a new relationship with the soils beneath their boots.

But is change happening quickly enough to make an impact on the future of our soil? Some experts are concerned.

Certainly the nomenclature “soil health” is more commonplace now across farm management plans and in everyday farm-gate conversations.

“In the early 2000s ‘soil health’ was a term hotly debated among scientists as a replacement for ‘soil quality’,” says Dr. Bianca Moebius-Clune, climate and soil health director of American Farmland Trust’s Climate and Soil Health Initiative.

More than 20 years later, Moebius-Clune says that “significant strides” have been made in normalizing the concept of soil health across the research and agricultural community.

But that normalization may not be translating to soil health practices on the ground fast enough.

“We need to scale up the drivers of adoption, because we don’t, as of yet, have a New Conventional Agriculture where soil health management systems are the new normal,” she says.

“Depending on which data we look at, no-till or reduced-till are in use on about half the acres at this point, and possibly still slowly growing, while cover crops increased from 10M acres in 2012 to about 15M acres in 2017 to about 18M acres in 2022 per the Ag Census, that’s 6% of today’s about 300M cropland acres,” she says.

“That’s progress, but not enough progress!”

Soil Health Principles

Moebius-Clune says that principles that promote healthy soil ecosystems are broadly applicable, but they need to be carefully adapted for success in a production system.

She points to four globally accepted principles that, together, can achieve an optimal soil health system:

- Maximize biodiversity
- Maximize living roots
- Maximize soil cover
- Minimize disturbance

Putting these into place on farms and ranches is to commit to stewarding what Moebius-Clune calls an “underground herd of livestock” or living organisms that contribute to a vibrant soil ecosystem and, therefore, high-functioning soils.

Beyond well-known practices like reduced tillage and cover cropping, those baseline principles can yield additional opportunities for farmers to invest in the health of their soil, including diversification of crop rotations, integrating livestock into cropping systems and precisely managing inputs. One innovative soil health tactic— biochar --has recently been included by USDA-NRCS through Soil Carbon Amendment Conservation Practice Standard 336, meaning financial and technical assistance is now available to help growers with implementation.

Soil Health Drivers

If the baseline principles are basic enough, why aren’t more farmers and ranchers jumping ahead in implementation?

Moebius-Clune says that adoption thus far has largely been driven by innovators, early adopters, researchers, NRCS and organizations like American Farmland Trust that have put time and effort into education, outreach and training. But, that work, she says, is not sufficient to take soil health adoption to the next level.

“We need to address the still significant social, financial and technical barriers to adoption,” she says.

American Farmland Trust is working in collaboration with partners across the value chain, including America’s Conservation Ag Movement , to break down those barriers through initiatives that develop farmer networks, science-and-practice grounded technical resources, decision-support tools and policy solutions to improve farmer access to resources.

Soil Health Benefits

Those soil health early adopters are seeing tangible benefits on farms and ranches, especially as climate extremes are becoming more prevalent.

“Healthier soils provide more resilience in extreme conditions,” says Moebius-Clune.

Moebius-Clune credits the “stable aggregates” of healthy soils for keeping pores open during periods of heavy rainfall events, allowing rainfall to infiltrate into the soil and store rather than washing topsoil downstream.

“This prepares systems to be more resilient during droughts when stored water in a deeper root zone remains available for longer,” she says, adding that diverse production systems are more likely to produce some crops that maintain yield when others fail.

The diversity of ecosystems in healthy soils can protect crops from pests and pathogens as well.

“There is even evidence in social science literature that farmers who manage for healthy soils may experience less stress and more inspiration, autonomy, confidence, freedom, flexibility and happiness,” she says.

Soil Health + Bottom Line

While soil health practices could lead to enhanced opportunities for farmers and ranchers looking to cash in on the carbon marketplace , Moebius-Clune cautions that there is still confusion and uncertainty holding many back.

But, even without that opportunity, American Farmland Trust has been putting soil health to the economic test by highlighting case studies where soil health penciled out in the bottom line.

“Our case studies show potential for return on investment through increased yields, decreased input costs, decreased long-term production system risk during extreme weather events and decreased maintenance needs and also quantify environmental benefits such as decreased erosion, nutrient and sediment pollution and increased carbon sequestration,” Moebius-Clune says.

“We know that farmers who successfully adopt these systems experience real economic returns on their soil health investments that can be quantified.”

Whenever you do your soil testing, Dennis Frame, a former University of Wisconsin Extension specialist and current nutrient management consultant, says you need to be consistent. In this video Frame offers advice on how to soil test the right way to get the best results.

Trusteed IRAs: why they are popular, who should consider them, what benefits they offer

Fri, 23 Sep 2022 20:01:45 GMT

Q: I’ve heard a lot about trusteed IRAs. How do they differ from traditional IRAs?

A: Simply put, trusteed IRAs offer potential tax benefits of traditional or Roth IRAs with the protection and control of a trust. They provide tax advantages that stretch into the future and offer the ability to control how, when and in what amounts assets are distributed. Trusteed IRAs have become more popular given some of the inherent limits of traditional IRAs and the growing prevalence of self-directed retirement accounts combined with the decline of pension plans. They also are more cost-effective than setting up a trust and are generally more compliant with tax laws.

Q: Who should consider a trusteed IRA?

A: There are several reasons why someone should consider a trusteed IRA, the most consequential of which is if an owner has an interest in controlling assets and realizing tax benefits beyond their lifetime. This can mean an owner is concerned with the financial discipline or sophistication of heirs.

Other reasons include if an owner remarries and wants to provide for a current spouse as well as children from a previous relationship and/or is concerned about IRA management in the event of incapacitation.

Q: I’m in the middle of estate planning. How can a trusteed IRA help with the process?

A: They can help process if only to preserve the potential tax-advantaged accumulation of IRA benefits to pass on to heirs. Under traditional or custodial IRAs, a beneficiary is required to withdraw at least the Required Minimum Distribution (RMD) each year. However, a beneficiary may withdraw additional amounts, for any reason, at any time—and incur possible fees or tax penalties.

Additionally, owners can restrict payouts to a beneficiary to the RMD, enabling it to operate as a spendthrift trust. At the owner’s death, the trusteed IRA would be automatically split into separate accounts for individual beneficiaries, with distribution terms defined for each account.

Another benefit is that estate plans don’t need to be rewritten or updated; trusteed IRAs can be added independent of an estate plan to protect IRA assets which legally pass outside of wills.

Q: Is a trusteed IRA better suited to farmers or owners of farm assets?

A: Not expressly, but a trusteed IRA can play an important role in legacy planning and preservation of farm assets over multiple generations. Given the growing generation gap among farming families, trusteed IRAs could be a way help preserve farm family values over generations from beyond the grave. Moreover, as farm economics continues to change, farmers may find value in the highly customizable nature of trusteed IRAs. In the event of a divorce in the family, for example, assets can be made to not leave the family’s bloodlines.

Q: Are there any downsides to trusteed IRAs?

A: Given that a trusteed IRA requires a corporate trustee, it’s harder to change ownership and family members cannot be named as trustees. Not all financial institutions offer trusteed IRAs so they may not be widely available to interested clients. Additionally, while they offer greater customization and more control, trusteed IRAs carry some limits. To have the highest level of customization and control, a trust would need to be created.
