The Role of Irrigation and Wastewater: Comparison of Subsurface Drip Irrigation and Furrow Irrigation

2003, Las Vegas, NV July 27-30, 2003, 2003
This study was conducted to compare two different irrigation systems, subsurface drip irrigation (SDI) and furrow irrigation (FI) in terms of water use efficiency as well as viral contamination and survival when tertiary effluent is used for irrigation water. The effluent was injected with bacteriophages of PRD1 and MS2.

Effect of Subsurface Drip Irrigation on Cotton Plantations

Water Resources Management, 2006
During the cultivation periods of 2001 (a dry year) and 2002 (a wet one), an experimental cotton field was irrigated using a subsurface and a surface drip system. Both systems included drip-lines 17-mm in diameter, with emitters discharging 3.8 l/h and spacing 1 m. The treatments included four irrigation levels.

Automation of Subsurface Drip Irrigation for Crop Research

World Congress of Computers in Agriculture and Natural Resources, Proceedings of the 2002 Conference, 2013
Automatic feedback control of precision irrigation scheduling allows the determination of optimum soil water potential for crops, close determination of N fertilizer requirements, and other measures of crop development and yield responses. Soil water potential (SWP) was measured with granular matrix sensors (GMS; Watermark Soil Moisture Sensors ...

SUBSURFACE DRIP IRRIGATION FOR BERMUDAGRASS WITH RECLAIMED WATER

Transactions of the ASAE, 2004
Subsurface drip irrigation was compared to sprinkler irrigation of bermudagrass turf in a multi-year experiment using reclaimed water. The experimental plots were established with sprinkler irrigation. During the following three irrigation seasons, plots were irrigated when the average soil water content in the upper 30 cm of soil decreased below 20%

Unique Challenges with Subsurface Drip Irrigation

2009 Reno, Nevada, June 21 - June 24, 2009, 2009
This paper will discuss from a conceptual standpoint many of the challenges of subsurface drip irrigation (SDI). Topics will include soil water redistribution as affected by soil type and soil characteristics, nutrient availability, differential crop response, system installation concerns, and system maintenance issues.

Effect of subsurface drip irrigation on onion yield

Irrigation Science, 2008
Subsurface drip system is the latest method of irrigation. The design of subsurface drip system involves consideration of structure and texture of soil, and crop’s root development pattern. A 3-year experiment was conducted on onion (Allium Cepa L., cv.

Corn Production: A Subsurface Drip Irrigation Approach

Applied Mechanics and Materials, 2014
Jilin Provincial Academy of Agricultural Machinery initiated studies in 2000 to develop the methodology for successful application of subsurface drip irrigation (SDI) for corn production on the deep silt loam soils of the northeast plains, China. Irrigation water use for corn can be reduced by 37–52% when using SDI compared with more traditional forms ...

Subsurface Drip Irrigation: Status of the Technology in 2010

Transactions of the ASABE, 2012
Subsurface drip irrigation (SDI), although a much smaller fraction of the microirrigated land area than sur- face drip irrigation, is growing at a much faster rate and is the subject of considerable research and educational efforts in the U.S. This article discusses the growth of SDI, highlights some of the research and extension efforts, and points ...

NITROGEN FERTILIZATION FOR SUBSURFACE DRIP–IRRIGATED CORN

Transactions of the ASAE, 2001
Microirrigation can potentially “spoon feed” nutrients to a crop. Accurately supplying the crop’s nitrogen (N) needs throughout the season can enhance crop yields and reduce the potential for groundwater contamination from nitrates. A 2–year study (1990–1991) was conducted on a Keith silt loam soil (Aridic Argiustoll) to examine combinations of both

Longevity and Performance of a Subsurface Drip Irrigation System

Transactions of the ASABE, 2017
Abstract. System longevity is an important economic factor to minimize amortized investment costs for subsurface drip irrigation (SDI), especially when growing lower-value commodity crops such as field corn. Kansas State University established a research site in 1989 at a research center to study SDI.
