Conserve water in a landscape by following a prescribed sequence in designing and managing the site.

Beauty and utility traditionally have been the purposes of home landscapes. Because water -- in both quality and quantity -- is becoming a limited resource, conservation has become a third goal. The homeowner can achieve all three by using careful, comprehensive planning.

You can reduce water consumption by 40-80 percent by following an appropriate sequence in designing and managing your site.


Ec91-735 The Impact Of Nitrogen And Irrigation Management And Vadose Zone Conditions On Ground Water Contamination By Nitrate-Nitrogen, K.D. Frank, Darrell Watts, Andrew Christiansen, Edwin Penas Jan 1991

Ec91-735 The Impact Of Nitrogen And Irrigation Management And Vadose Zone Conditions On Ground Water Contamination By Nitrate-Nitrogen, K.D. Frank, Darrell Watts, Andrew Christiansen, Edwin Penas

The single largest contaminant found in ground water samples taken throughout Nebraska is nitrate-nitrogen (nitrate-N). Much of it reaches the ground water as a "non-point source" contaminant leached out of the crop root zone.

Nitrate-N is essential to corn production. However, when leached from the crop root zone it can become a major source of ground water contamination. There are serious contamination problems in shallow aquifers beneath several river valleys in Nebraska. Increasing nitrate-N concentrations are beginning to appear in deeper aquifer.


G91-1043 Water Runoff Control Practices For Sprinkler Irrigation Systems, William L. Kranz, David P. Shelton, Elbert C. Dickey, John A. Smith Jan 1991

This NebGuide describes techniques to help reduce water runoff from fields irrigationd with sprinkler irrigation systems.

Water runoff is often a problem associated with sprinkler irrigation systems operated on sloping terrain. Soil particles, fertilizers and pesticides can become part of runoff waters and can be moved from their target locations, causing degradation of surface water quality.

Other potential problems associated with runoff include a lack of soil moisture in localized areas of the field, crop nutrient deficiencies, washed-out seeds or plants, and increased irrigation water pumping costs.
