General Information
Research Title
Effects of irrigation non-uniformity on nitrogen and water use efficiencies in shallow-rooted vegetable cropping systems
Research Specifications
Crop: Carrot
Soil Type:
County, State: Kern, California
Year: 1999
Authors
Sanden, Blake, Mitchell, Jeff, Wu, Laosheng
Summary/Abstract from Original Source
Research Highlights
Design and Methods
- This report focuses on the effectiveness of conventional and alternative lateral spacing of sprinkler irrigators in reducing water usage and increase N fertilizer efficiency in a carrot cropping system.
Results
- Lateral sprinkler spacing between 33-47 feet did not differentially influence yield, N distribution, or nitrate leaching.
- The results of this study suggest that natural variability in soil characteristics, as opposed to lateral spacings, are the most important control of deep water percolation and nitrate leaching when irrigation is properly scheduled.
