ACTION
PLAN
The primary goal of the ADMS Task Force is to develop a national effort to
implement improved drainage water management practices and systems
that will enhance crop production, conserve water, and reduce
adverse off–site water quality and quantity impacts. The
Task Force will initially focus on reducing nitrate-nitrogen
losses from agricultural lands carried in drainage flows by about
30 percent and improving the economic return of agriculture drainage.
As this first goal is realized, the Task Force will look to implement
and develop multiple drainage water management practices and
systems that will address other site-specific water quality issues,
as well as the integration of other water, pest, and nutrient
management practices that are more suited to advanced drainage
water management technologies. The vision and motto of the ADMS
Task Force is “Save our Precious Resources from Going
Down the Drain.”
Agricultural
drainage improvements can be made to either the surface or the
subsurface system, or a combination of both. Subsurface drainage
is designed to remove standing water from the soil surface that
is not removed by surface drainage. Removing water from the surface
is important because it affects the water table depths and the
right amount of surface drainage can benefit riparian areas,
wetlands, and stream corridors. Improved drainage water management
includes land leveling and smoothing; the construction of shallow
ditches and grass waterways; the construction of shallow ditches
and grass waterways; and the construction of surface water inlets
to subsurface drains; which empty into open ditches and streams.
The Task Force is promoting three basic improvements in drainage
water management practices and strategies. These are structures
placed for management of surface and subsurface drains (controlled
drainage systems), management strategies to maintain water tables
within fields (subirrigation or water table management systems),
and replacement systems that can be managed (subsurface drainage
systems which are installed shallower than conventional systems).
In the
past, surface and subsurface drains were used to remove excess
water from the soil to provide conditions that are more favorable
for crop production. In recent years, science has shown that
improved drainage management is a key to enhancing surface and
ground water quality from agricultural lands. In addition to
reducing nitrate-nitrogen losses, science has shown that improved
drainage management is a major factor in: (1) reducing surface
runoff of pesticides, (2) designing and operating more efficient
wetlands and conservation buffers, (3) improving fish and wildlife
habitat, (4) reducing problems associated with invasive plants
in wetlands and water ways, (5) reducing hazards associated with
salts and toxic elements on irrigated lands, and (6) increasing
opportunities for enhancing water conservation on range, pasture
and crop lands while enhancing agricultural productivity without
requiring additional agricultural lands. Practical experience
has shown that modifications that allow for management of existing
drainage systems, or the replacement/installation of new systems
with improved designs allows for better management of quantities
and timing of water releases. Farmers are finding that these
modifications will reduce losses of nutrients, such as nitrates,
and additionally conserve water in the soil for crop uptake and
use during drier periods.
The initial
focus of the ADMS Task Force will be in the six states of Iowa,
Illinois, Indiana, Ohio, Minnesota, and Missouri. Previous research
in these states has shown that a large percentage of the nitrate
that migrates down the Mississippi and Ohio Rivers comes from
surface and subsurface drainage discharge and base flow in this
Midwest region. High concentrations of nitrate-nitrogen, phosphorus,
and pesticides can be major concerns in streams, rivers, lakes,
and reservoirs for either drinking, fishing, or swimming issues.
The Environmental Protection Agency (EPA) is currently reviewing
its ongoing implementation of Total Maximum Daily Load (TMDL)
program with particular emphasis on how to best address agricultural
nonpoint source pollutants. The nitrate-nitrogen loadings from
these key states are considered to be a significant contributor
to Hypoxia zone in the Northern Gulf of Mexico. Perhaps more
important to the Midwestern farmer, the economic and conservation
benefits of managed drainage systems are noteworthy, namely:
(1) with less nitrate loss from the cropland in drainage discharge,
smaller amounts of fertilizer may need to be applied, which would
reduce production costs, and (2) during dry growing seasons,
controlled-drainage conserves soil-water for crop use, thus improving
potential yields.
Initial
ADMS Objectives:
The ADMS
Task Force proposes first to integrate, synthesize, and recommend
applications of existing technologies for possible technical
and financial assistance by NRCS and other Federal and State
agencies. The ADMS Task Force will also assist in developing
educational and training materials needed to implement the science-based
management practices and technologies. Lastly, the ADMS Task
Force will recommend additional research and development activities
and priorities needed in the future to improve agricultural viability
and environmental quality. The four major objectives for the
ADMS Task Force are as follows:
- Provide additional
scientific and technical assistance information for the development
of environmental and societal goals and objectives, and performance
measures for improved drainage water management practices
and systems.
- Make sure that
the completed and ongoing data sets for drainage improved
water management systems are catalogued, cross referenced,
and integrated into a national agricultural database.
- Provide coordination
of the technical, educational, and extension materials on
the design, implementation, and operation of drainage water
management systems that supports its success and sustainability.
- Identify key technology
gaps in drainage water management systems and related agricultural
management systems and propose coordinated research, inventory,
data collection, modeling, and technical assistance information
programs to address the gaps.
- Initial

Based
on the four primary objectives, the ADMS Task Force has
initially proposed 14 action items:
