Bioreactors

Bioreactors are an edge of field conservation drainage practice that is installed to improve water quality by reducing the amount of nitrates in drainage tile water before it is released to surface waters.

Results of research on pilot scale and field scale bioreactors show reduced nitrate levels in drainage water by 10% to greater than 90%, depending on the bioreactor, the drainage system, and the weather patterns for a given year. Some materials can be added to bioreactors to reduce phosphorous levels if present in the tile drainage water.

A bioreactor is a subsurface trench located along the edge of a field that is filled with a carbon source, most often wood chips. The trench is usually lined with a polymer material prior to the addition of the carbon source material to manage the water flows in the structure. A fabric material and topsoil cover the top of the bioreactor. The carbon source in the trench serves as a substrate for bacteria that breaks down the nitrate through denitrification processes converting it to nitrogen gas.

Water level control structures manage the flow of water into the bioreactor and allow excess flows to bypass the system so that the tile drainage system isn’t restricted. Usually two water control structures are used in the bioreactor design and each structure plays a different role. The inflow structure routes the water into the bioreactor, allowing excess water to bypass the bioreactor in the existing tile main during high-flow events. The outflow control structure manages the water within the bioreactor, ensuring that there is the proper time to remove nitrates from the water as it flows through and before leaving the structure. Depending on the topography of the site, new design methods may allow one water control structure to manage both inflows into and outflows from the bioreactor.

Bioreactors can be retrofitted to nearly any existing tile drainage systems and do not usually require any change in the drainage system. Good planning and careful siting can lead to little or no land being taken out of production. Soil type is not a criterion for locating these structures, so they can go in just about any location. The lifespan of a bioreactor is estimated to be 15 to 20 years. The area immediately above the bioreactor is not suitable for field traffic as the materials in the bioreactor are generally soft and can compress. Any method to exclude traffic from that area is advised.

The USDA-NRCS has financial assistance available in most states for the installation of bioreactors. Many nonprofits, Conservation Districts and some state agencies also have funding available to assist with the cost of implementing these structures.

Reduce Nitrates and Phosphorus from Subsurface Field Drainage Systems

Nutrient loss through subsurface drainage systems is a major concern throughout the Midwest. This project sought to demonstrate and evaluate the effectiveness of a new conservation practice commonly referred to as a Saturated Buffer (SB). By hydrologically reconnecting a subsurface drainage outlet with an edge-of-field buffer this practice takes advantage of both the denitrification and plant nutrient uptake opportunities that are known to exist in buffers with perennial vegetation as a way to remove nutrients from the drainage water. The USDA-NRCS developed an interim practice standard (739 – Vegetated Subsurface Outlet) in conjunction with this project. Continue reading….

Manage Tile Drainage Water

Underground water control can regulate water levels, direct water into the soilor filter nitrates. 


THINK DIFFERENT

Nitrate management in tile water is a big reason why this water control structure has slowly gained a foothold in the Corn Belt, but its potential for providing timely water to corn and soybeans may spell the future for this underground tile water management tool. Some see the day when hundreds of thousands of acres of tile-drained land will use smart drainage systems to supply water as well as drain it away. Learn more here

Drainage Gains In Water Management

Drainage Gains In Water Management
Original source: Crop Life

Of the many practices available to stem nutrient losses, drainage water management is getting more attention. What’s ahead here? Charlie Schafer, president of Agri Drain Corp., Adair, IA, says site-specific structural practices — using an engineered watershed-scale systems approach — will manage and treat water that starts at the top of the slope where rainwater falls.WQ 1

In fact, automatically managed, swarm intelligence-based operating systems are being designed with built-in forecasting that drain, hold, and add water back into systems. Schafer says they offer quantifiable reductions that will provide the greatest benefit and lowest cost to producers and downstream communities.

But beyond drainage systems, he says growers can treat and reduce nutrient concentrations by installing edge-of-field practices such as bioreactors, saturated buffers, and nitrogen treatment wetlands. These options give producers the ability to manage water levels, maximize yields and reduce nutrients leaving their fields.

Then too, he adds, NRCS practices such as tile outlet terraces, improved grass waterways, ponds, water, and sediment control basins and wetlands will reduce nutrient loss and improve water quality. The array of choices is encouraging.

Ultimately, “if we utilize available practices, technology and water quality trading, there will be no need for regulations,” Schafer says.

Traditional funding sources, including USDA, will continue to support conservation practices. “But we need a game changer to get us to where we need to be, in an acceptable amount of time, due to increased weather variability and a growing world population,” he believes. “When we can manage, store, treat, and reuse water on-farm, the producer and downstream communities will benefit and will share in the associated costs through a market-based approach.”

Innovations in Water Management to Improve Crop Productivity and Water Quality

Several key innovations are coming on line to dramatically improve both agricultural productivity and water quality by management of water flowing through tile lines. The first of these is Drainage Water Management where water is held in the field during the dry periods of the growing season and during fallow periods to improve productivity, and water quality. The second is Sub-Irrigation, which uses the same subsurface tile lines used for drainage to irrigate crops. These two systems can dramatically improve farm economic viability and cost-effectively reduce nutrient loss to waterways.

DWM refers to controlling the flow of water discharged from tile lines to improve environmental performance and agricultural production. Without controls, tile lines drain water and associated materials from fields around the clock year round. However, drainage typically is only needed during
part of the year, and closing off drainage during most of the year will significantly reduce nutrient loss and improve yields.

Iowa League of Cities Receives Conservation Innovation Grant to Develop Water Quality Offset Program

 

United States Secretary of Agriculture Tom Vilsack announced today that the Iowa League of Cities will be one of the 2015 recipients of a Conservation Innovation Grant (CIG) that is administered by the Natural Resources Conservation Service (NRCS). The League will receive a CIG grant totaling over $700,000 over 3 years to fund the development of a Water Quality Offset Program in Iowa under the framework outlined in the Iowa Nutrient Reduction Strategy. The ultimate goal of an offset program is to generate the same or increased nutrient reduction at a reduced cost to municipalities and their ratepayers. The CIG program looks for innovative approaches toward increasing usage and effectiveness of conservation practices, and has funded other market based conservation efforts in the past.

 

The grant funds will leverage the ongoing watershed projects in the cities of Dubuque and Storm Lake who have utilized state programs to develop projects upstream from their communities. These cities have collaborated within their watersheds through the State Revolving Fund’s Sponsored Project Program and an Urban Water Quality Initiative award from the Iowa Department of Agriculture and Land Stewardship to develop projects with environmental benefits that have value to their citizens. These cities are holistically looking at their environmental impact to understand if this work can have a reduction of costs benefit to their citizens.

 

Upon the announcement, General Counsel for the Iowa League of Cities, Dustin Miller stated “We hope this grant acts as a catalyst to accelerate the development of a water quality offset system. Such a system in Iowa will not be the whole solution to water quality in the state, but what we have seen in other states is that, done the right way, such a flexible system can achieve the same or even greater environmental impact in a watershed at a reduced cost to ratepayers.”

 

The application was a partnership between the two cities, proven experts in the field environmental science, engineering firm Kieser & Associates and law firm Troutman Sanders with the goal of developing innovative, practical solutions that are right for Iowa. Combined these two groups have created over 25 different credit trading systems across the country.

 

As part of the grant, the League has created a Technical Advisory Committee that is made up of a diverse group of stakeholders from agriculture, environment, city, and industry. Members of the group will being meeting regularly to tackle questions around this framework development to come up with some sort of consensus about how a system should be structured in Iowa.

 

The announcement comes the same week that the EPA and USDA are hosting a National Workshop on Water Quality Markets in Lincoln, NE featuring regional water quality trading forums, conservation finance opportunities and recent developments in economics, science & technology. Experts in water quality markets from across the country have come together to discuss trends across the country and both agencies have asked the Iowa League of Cities to participate on panels related to water quality market development in the Mississippi River Basin and the impact of the CIG funding to spur this development.

 

 

The Iowa League of Cities is the oldest, continuously operating municipal league in the country. Founded in 1898, the League is a not-for-profit organization that serves at the unified voice for cities, providing advocacy, training and guidance to the cities of Iowa.
