Michigan’s soils, hydrology, and topography make tile drain systems an essential element of agricultural systems in many areas of Michigan, and the precipitation pattern seen in 2021 in our state spotlights opportunities to use this technology as a risk mitigation tool. This year, and in several recent years, periods of substantial drought are broken up by major rainfall events, delivering several inches of rain in a short period of time. This complicates management of water in fields, and can exacerbate dissolved P and N losses through tile drains.
Drainage water management (DWM) systems allow for the adjustment of the water table elevation in fields, allowing for a naturally high-water table during non-cropping times of the year. This allows for greater water infiltration to groundwater while keeping unnecessary water out of drainage systems. During the growing season, the water table can be lowered to the typical functional level of the drain tile system, providing all the same benefits of tile drainage that growers expect.
DWM systems also allow for raising the water table during drought events, retaining moisture in the soil profile for crop use. Unlike some other nutrient loss reduction practices, DWM systems don’t take farmland out of production or require changing in-field agronomic management. And they require minimal time to adjust water levels, taking just minutes to add or remove boards in the control structure.
Cost-share assistance programs are available in many counties. Growers are encouraged to contact their local conservation district offices to learn more about improving their tile drainage systems with drainage water management technology. As a conservation practice, DWM retains flexibility of in-field agronomic management, does not remove land from production, offers immediate yield increase potential, and has assessable cost-share opportunities – a unique combination and something to be considered in planning for 2022 and beyond.

The fall harvest season marks the start of planning for the 2022 crop, beginning with nutrient management. Fertilizer application plans combine soil test information, yield performance in the field, and detailed fertilizer recommendations to create nutrient management that optimizes crop performance while limiting environmental impacts. With fertilizer prices at higher levels than in past years, comprehensive nutrient management plans are more important than ever.
Nutrient management decisions should be driven by data, including assessments of existing soil nutrient levels. Intensive sampling approaches such as grid or zone soil testing provide high levels of resolution to precisely identify optimal nutrient application rates.
Fall is an excellent time to test soils for nutrient levels, both for fertilizer applications that might be made yet this fall, as well as complete nutrient management plans for the following year’s crop. Soil test data becomes even more powerful when combined with yield data to assess crop removal. Modern technology allows for nutrient application rates to closely match what’s been removed from the field through grain. Multiple years of data also allow for the identification of productivity zones in the field and provide a better determination of future yield targets than one year’s data alone.
Today’s fertilizer recommendations are the result of long-term determination of crop response to nutrient application rates, timing, and placement. Underpinned by scientific measurement, these recommendations are also the product of observed crop response in the field.
Putting all these pieces of nutrient management together is where crop advisors excel. Not only are these certified professionals current on new advances in nutrient management, but they also can see trends across a region that might not be seen on a farm level. As growers begin to prepare for the 2022 crop year, consulting with a crop adviser to implement purposeful fertilizer management plans is an important first step.
LANSING, Mich. – A recent report from the U.S. Department of Agriculture – announced on the 10th anniversary of the U.S. Government’s BioPreferred Program – shined a spotlight on the positive economic impact of innovative, biobased products in Michigan and across America. Biobased products include those manufactured with agricultural products, including Michigan-grown soybeans.
“Michigan’s soybean farmers are proud to contribute to a biobased products industry that generates billions of dollars in economic activity for our state and reduces America’s reliance on oil,” said Janna Fritz, CEO of the Michigan Soybean Committee. “From auto components, to cleaning supplies, to construction materials and beyond, Michigan-grown soybeans are used in thousands of products Americans use every day – providing renewable options for consumers and helping to bolster our state’s economy.”
The report noted Michigan is in the top ten states in direct value added to the biobased chemicals sector (9th), and direct value added in the biobased plastic bottles and packaging sector (6th). According to the report, the biobased products industry:
“This USDA report affirms the importance of biobased product manufacturing as a pillar of our economy here in Michigan, and across America,” said Chuck Lippstreu, president of the Michigan Agri-Business Association. “When new markets are developed for Michigan’s soybean farmers, rural businesses also benefit. This new report clearly demonstrates the value delivered back to our state by the creation of innovative new biobased products, including those made with Michigan-grown soybeans.”
