Mapping Tile Drain Systems: Using Technology to Find Grandpa’s Tile

How can you find old tile lines without spending hours digging holes? During our webinar on Wednesday, Kevin Erb, Conservation Professional Training Program coordinator at the University of Wisconsin-Madison, Division of Extension, discussed available strategies and tools, most of which use information that the farmer already has, or that is readily available.

Knowing where old tile lines are located makes upgrading easier, and due to the connectedness of tile systems, the impacts of tile issues can stretch beyond the field or property line. Erb shared some history of tiling, explaining that due to the difficulty of installing clay or concrete, tile systems were not installed in neat grid patterns, but instead from wet spot to wet spot, which can make locating them difficult generations later.

Erb explained that air photos can be a helpful tool, but that not everything that looks like tile on old air photos is tile. Because of this, it’s important to look at multiple years of air photos to determine what actually is tile. GIS software can be helpful to overlay the years of photos if you have it available, but you can also assess air photos by hand, by comparing multiple years of photos side-by-side. Google Earth’s time machine function allows you to click through multiple years of data, which can enable you to see things that show up on some years, but not on others, due to soil moisture and temperature variations.

With combinations of air photos, lower-level drone photos, and field observations, you’ll start to be able to map out where the drainage tiles are located. It’s also important to mark the location of tile blowouts when you see those in fields, to better understand the system. Yield maps can also be useful tools for determining drainage tile locations. Once you’ve started to create your tile map, yield data can help you located areas of unmapped tile and help you identify areas where your tile might not be working well.

As you build your tile map, Erb suggested color coding the tile lines by the sources through which you found them. This can help you see where there might be data missing and may help you identify areas that you need to do further research on to find the tile lines. It is also helpful to map more than just your field, including at least every field next to yours, if not the entire section, so that you can better understand the complete picture of tile drainage in your field.

To learn more about creating a tile map, other non-Google sources of air photos, the Budweiser/Euchre method, and other technology that can be used to map tile lines, such as ground penetrating radar, watch the full webinar!

December 2 Webinar: Mapping Tile Drain Systems: Using Technology to Find Grandpa’s Tile

Using readily available information to map drainage tile is the topic of the Iowa Learning Farms webinar on Wednesday, December 2 at noon.

Drainage tile is typically ignored after installation, until a problem develops, or the farmer wants to add onto the system. While there are unique ways of finding tile when you need to, such as witching, pressurizing, and smoking, there are also a number of strategies and tools that farmers can use to locate drain tile without digging a dozen holes with a backhoe.

Kevin Erb, Conservation Professional Training Program coordinator at the University of Wisconsin-Madison, Division of Extension, will discuss these strategies and the tools available. Most of the tools use information that the farmer already has, or that is readily available.

“One of the more frustrating parts of farming is spending the better part of a day (or more) digging random holes with a backhoe to find old drain tile. And waiting until the poorly drained areas show up on next fall’s yield maps means lost yield and profit. Investing time now and mapping out your tile systems is a worthwhile investment that will save time in the future,” said Erb. “There are free and low-cost options that make locating older tile systems simpler than ever before. And it can be fun to combine yield maps, air photos, and other resources to make it happen.”

In addition to managing the Conservation Professional Training Program, Erb’s extension programming includes manure management, soil moisture management, drainage, soil health, and managing agricultural systems in karst areas.

Managing Stormwater in the Urban Landscape—Don’t Run Off!

John McMaine, assistant professor and water management engineer extension state specialist at South Dakota State University, was the presenter of the Iowa Learning Farms webinar on Wednesday. During the webinar, McMaine explored urban stormwater management and the effect that low impact development can have on water quantity and quality.

McMaine explained how even small increases in impervious surfaces can have dramatic impacts on how much runoff there is. Water quantity then goes from being infiltration dominated to being runoff dominated, which can also lead to water quality problems.

Urban development leads to an increase in impervious area, which in turn increases peak flow and total water volume. New pollutants are also introduced to the area and there is no barrier that prevents these pollutants from reaching the water bodies. Changes in precipitation and climate can also impact the urban water cycle.

In order to address these issues, structural and non-structural practices can be used. Structural practices include the use of rain gardens, rain collection barrels, permeable pavers, and more. Non-structural practices include maximizing green spaces, minimizing impermeable surfaces, and protecting native soils, among others. While these practices can potentially benefit everyone, it can be difficult to know who is responsible for their implementation and the costs associated.

We have many great webinars available here, including this one from May that discusses specific urban stormwater management practices.

November 18 Webinar: Don’t Run off!—Managing Stormwater in the Urban Landscape

The Iowa Learning Farms webinar at noon on Wednesday, November 18 will explore urban water management and low impact development.  

Most rainfall in an urban area becomes runoff, which leads to greater peak flow and runoff volume than before the land was developed. Low impact development (LID), also known as green infrastructure or green stormwater infrastructure, is a paradigm of managing urban runoff by mimicking pre-development hydrology.

During this webinar, John McMaine, assistant professor and water management engineer extension state specialist at South Dakota State University, will explore how much impact LID can really have, the costs and benefits of the practice, and will challenge how we think about urban water management.

“Even small increases in impervious area (roofs, driveways, roads, parking lots) can lead to significant water quality and quantity issues. LID stormwater management mitigates these issues by restoring predevelopment hydrology,” said McMaine.

McMaine works with water management and water quality across agricultural and urban settings to research and develop practical water-centered solutions and empower stakeholders to implement strategies that improve water quality and quantity issues.

Finding the Right Fit for Soil Health Practices

Our webinar on Wednesday featured Dr. Abbey Wick, North Dakota State University soil health specialist and associate professor, who shared soil health approaches farmers have used in the northern plains and how they’ve tweaked those approaches to achieve their goals.

Wick explained the importance of creating the right mindset to try out new soil health practices and being willing to adjust the approach in order to meet the on-farm goals. She shared the experiences of farmers who she has worked with, both what practices they’ve tried, and also the lessons that they’ve learned. Some of the lessons learned that were highlighted were:

  • Pick your goal
  • Ask questions
  • Treat cover crop like a cash crop
  • Cover crop by soil texture
  • Find out why something worked or didn’t work
  • Try things out on your worst acres
  • Simple is okay
  • Share what you’re learning with others and get their input

Wick explained these lessons learned, along with many other during the webinar. She also shared some positives results of soil health practices that farmers are seeing, such as improved water management during wet spring and fall periods and noticeable soil health improvements in clay soils.

November 11 Webinar: Finding the Right Fit for Soil Health Practices

How to create the mind-set needed to evaluate systems and develop a customized approach for adopting soil health practices that meet on-farm goals is the topic of the Iowa Learning Farms webinar at noon on Wednesday, November 11.

There isn’t a prescription for the adoption of soil health practices; it’s more of a pursuit. Farmers find a practice that could accomplish an on-farm goal and then adjust that approach as they learn how it fits their system. Dr. Abbey Wick, North Dakota State University soil health specialist and associate professor, will share approaches farmers have used in the northern plains and how they’ve tweaked those approaches to achieve their goals.

“The use of soil health practices varies by region, by farm and by field—learning how to think through a problem and pull together a set of practices is how new management approaches are successfully adopted on-farm,” said Wick who works alongside farmers, consultants, industry and researchers to come up with both science-based and practical soil health management approaches that can be adopted on-farm with reduced risk.  

Wick emphasized the importance of the thought process around soil health for the successful adoption of practices. She hopes the webinar will help participants think through some ideas to use on their farm, or in their program, research or business.

Nutrient Reduction Progress at Iowa Wastewater Treatment Facilities

The Iowa Learning Farms webinar on Wednesday discussed the progress that has been made by Iowa’s municipalities and industries toward reducing point source pollution reaching Iowa’s waterways. Adam Schnieders, water quality resource coordinator with the Iowa Department of Natural Resources (DNR), shared information about the progress to date, after eight years of implementation.

Iowa’s largest communities and industries have a significant role to play to help meet the state’s nutrient reduction goals. Understanding that role and the progress to date paints a clearer picture of how the many facets of Iowa’s Nutrient Reduction Strategy fit together and work today. Schnieders shared some background information about how far Iowa has come in terms of water quality, and the importantce of wastewater treatment facilities integrating nutrient removal technology into their operations.

The data from 1992 to 2013 in the chart above is an estimate that is based on population growth and increased flow at the wastewater treatment facilities. With the finalization of the Iowa Nutrient Reduction Strategy, total nitrogen and phosphorus annual load began to be measured at the facilities. Although there appears to be a sharp increase after 2013, this is likely due to the limitations of the previously estimated loads. Now that the loads are being measured, progress toward the goals of the strategy can also be measured.

November 4 Webinar: Nutrient Reduction Progress at Iowa Wastewater Treatment Facilities

Iowa Learning Farms will present a webinar at noon Wednesday, November 4, which will assess the progress made by Iowa’s municipalities and industries toward reducing point source pollution reaching Iowa’s waterways.

Iowa’s largest communities and industries have a significant role to play to help meet the state’s nutrient reduction goals. Understanding that role and the progress to date paints a clearer picture of how the many facets of Iowa’s Nutrient Reduction Strategy fit together and work today.

In 2013, the Iowa Nutrient Reduction Strategy called for significant nitrogen and phosphorus reductions from Iowa’s largest municipal and industrial wastewater treatment plants. The strategy laid out unique policy approaches to achieve these ambitious reductions. During the webinar, Adam Schnieders, water quality resource coordinator with the Iowa Department of Natural Resources (DNR), will discuss the progress to date, after eight years of implementation.

“I hope participants take away an appreciation of the magnitude of the lift Iowa’s communities and industries are undertaking to meet the point source goals of the Iowa Nutrient Reduction Strategy,” said Schnieders, who is responsible for management and coordination of clean water programs and policies for the DNR. “These efforts are resulting in significant progress not only toward nutrient reduction at Iowa’s wastewater treatment facilities, but also in partnerships and collaborations with farmers to help each other improve Iowa’s water quality for a variety of mutual benefits.”
