Clogging of buried drip irrigation systems

Application of alternative fumigants through drip irrigation systems.

ABSTRACT Strawberry fields in California (9,500 ha annually) are pre-plant fumigated with methyl bromide and chloropicrin to prevent serious soil pest and disease problems. Although soil fumigation with methyl bromide has ensured stability of strawberry production, its use is being discontinued because of its effect on stratospheric ozone. The likely short-term alternatives such as 1,3-dichloro...

Design Considerations for Subsurface Drip Irrigation (SDI) Systems

Gary A. Clark Research Irrigation Engineer Quick Facts Subsurface drip irrigation (SDI) is a low-pressure irrigation system that uses polyethylene driplines that are permanently buried below the soil surface. Water drips to the surrounding soil through built-in emitters (specialized small openings). SDI places water directly into the root zone of the crop. It may improve yield due to high appli...

Optimize Above–ground Drip Irrigation Systems for Small Areas

Drip irrigation systems offer the potential for efficient irrigation of high value crops and have proven feasible from engineering and agronomic standpoints in the northern Great Plains. However, little information is available in this region regarding the optimum design and economics of these systems. The objective of this study was to develop a computerized model for design and economic optim...

Using Irrigation to Manage Weeds: A Focus on Drip Irrigation

Advantages and Disadvantages of Subsurface Drip Irrigation

The advantages and disadvantages of subsurface drip irrigation (SDI) as compared to alternative irrigation systems are conceptually discussed. Each category (advantages and disadvantages) is subdivided into three groups: 1) Water and soil issues; 2) Cropping and cultural practices, and 3) System infrastructure issues. The adaptation and adoption of SDI systems into diverse cropping systems, geo...
