Subsurface Irrigation Helps Nebraska Producer Save Water, Energy and Money

Anyone who has gotten up at 4 a.m. to switch gates on irrigation pipe or untangle a center pivot after a wind storm, knows that despite all the advancements in irrigation, there is still a long way to go.

The Ogallala Aquifer Initiative

Using a comprehensive set of conservation practices, the Ogallala Aquifer Initiative (OAI) aims to reduce aquifer water use, improve water quality and enhance the economic viability of croplands and rangelands in Colorado, Kansas, Oklahoma, Nebraska, New Mexico, Texas, South Dakota and Wyoming.

Currently, the use of groundwater from the aquifer is unsustainable as withdrawals exceed the natural recharge of the aquifer. Intensive agricultural and industrial practices threaten the quality and quantity of the water source.

America’s stewardship of this natural resource is critical. Stretching from western Texas to South Dakota, the Ogallala Aquifer supports nearly one-fifth of the wheat, corn, cotton and cattle produced in the United States. Underlying approximately 225,000 square miles of the Great Plains, water from the aquifer is vital to agricultural, municipal and industrial development, making up 30 percent of all groundwater used for irrigation in America.

The Natural Resource Conservation Service (NRCS) State Conservationists in OAI states collaborated with local conservation districts, state environmental agencies, land grant universities and NRCS State Technical Advisory Committees to complete inventories and determine high priority resource concerns within the OAI area.

How does OAI Work?

OAI is designed to reduce the quantity of water removed from the aquifer, improve water quality using conservation practices and enhance the economic viability of OAI-area croplands and rangelands by:

  • Improving irrigation efficiency by a minimum of 20 percent on 3.7 million acres
  • Applying nutrient management and conservation cropping system practices on a minimum of 3.4 million acres
  • Establishing an equilibrium level of water recharge and water removal from the aquifer over time
  • Maintaining water quality to Environmental Protection Agency (EPA) standards
  • Helping agricultural producers save billions of gallons of water from the Ogallala Aquifer
  • Assisting agricultural producers in developing conservation plans and prescribed voluntary conservation alternatives specific to water quality and quantity resource concerns

To achieve these goals, NRCS will work with landowners to implement conservation practices such as:

  • Converting irrigated land to dry land
  • Planting non-irrigated permanent vegetation
  • Implementing nutrient and pest management
  • Adjusting cropping systems and perennial vegetation for haying, grazing, and wildlife habitat
  • Replacing inefficient, flood-irrigated systems to more efficient center pivot and Sub-surface Drip Irrigation (SDI) systems

Conservation activities are carried out using NRCS’s Environmental Quality Incentives Program (EQIP) and funding provided by state and local agencies.

The socially disadvantaged and limited resource farmers and ranchers in the project area have separate funding sources.

How does OAI Benefit Producers?

Agricultural producers will experience immediate benefits from participating in OAI through improved irrigation efficiency. Economic benefits include:

  • Improvements in irrigation water management help maintain the long-term viability of the irrigated agricultural sector
  • Water savings at the farm level help offset the effect of rising water costs and restricted water supplies on producer income

Improved water management reduce expenditures for energy, chemicals and labor inputs, while enhancing revenues through higher crop yields and improved crop quality.

How does OAI Benefit the Public?

Wildlife Protection – Increased river flow in the OAI region as a result of conservation measures will benefit the endangered interior least tern, whooping crane, pallid sturgeon and the threatened piping plover.

Water Conservation – Efficient irrigation systems and water management practices help conserve water and maintain farm profitability in the Ogallala Aquifer region. These practices also reduce the impact of irrigated production agriculture on water quantity and quality.

Water Quality – Improved water management helps minimize offsite water quality impacts of irrigated production agriculture by:

  • Lowering the amount of chemicals used in irrigated crop production
  • Decreasing field salinity and erosion
  • Slowing pollutant transport with drainage flows
  • Lessening pollutant concentrations in rivers and streams due to an increased flow of water

Partnership Opportunities

NRCS is building a foundation of partners from non-profit and private organizations, local, state, and federal governments and individuals across the Nation. Whether these partnerships augment funding sources, increase return on investment, or provide boots-on-the-ground support, NRCS and its partners are committed to helping people help the land.

NRCS collaborates with local conservation districts, state environmental agencies and land grant universities to complete inventories and determine high priority resource concerns within the OAI area.
