Subsurface Drip Irrigation and Fertigation of Broccoli

Soil Science Society of America Journal, 2002
Subsurface drip irrigation offers potential for increased water and N fertilizer use efficiency, and decreased groundwater NO 3 pollution. Replicated factorial experiments consisting of four rates of N fertilizer application (60–500 kg ha −1 ) and three

Fertigation Frequency for Subsurface Drip‐Irrigated Broccoli

Soil Science Society of America Journal, 2003
Subsurface‐drip irrigation and fertigation with fluid N fertilizer sources offers substantial flexibility for N fertilizer management. Fertigation events can be scheduled as often as irrigation, up to several times per day. However, because of system or management constraints very frequent fertigation may not be possible or ...

Frequency of Irrigation for Subsurface Drip-irrigated Corn

Transactions of the ASAE, 1994
Four time-based treatments and four soil water depletion-based treatments were used to evaluate the effect of irrigation frequency on the production of subsurface drip-irrigated corn. Cumulative soil water depletion was calculated and replenished every 1, 3, 5, and 7 days for the time-based treatments.

SUBSURFACE DRIP IRRIGATION: A REVIEW

Transactions of the ASAE, 1998
A comprehensive review of published information on subsurface drip irrigation was performed to determine the state of the art on the subject. Subsurface drip irrigation has been a part of drip irrigation development in the USA since its beginning about 1960, but interest has escalated since the early 1980s. Yield response for over 30 crops indicated

Subsurface drip irrigation in California—Here to stay?

Agricultural Water Management, 2015
Abstract Subsurface drip irrigation (SDI) has been used in California for over 30 years. Adoption occurred first in high value annual row crops. Over the years as drip irrigation materials, installation equipment, and irrigation scheduling tools have evolved, SDI has gained wider acceptance and is now being used in perennial crops as well on a ...

13. Subsurface drip irrigation

2007
When compared with other irrigation systems, subsurface drip irrigation (SDI) has advantages and disadvantages that should be carefully considered. There are many design and management similarities to surface drip irrigation (DI), but there are also some unique differences that affect uniformity, operation, and system longevity. Factors that affect SDI

Evaluation of Drip and Subsurface Drip Irrigation in a Uniform Loamy Soil

Soil Science, 2012
AbstractDrip irrigation DI is considered one of the most efficient irrigation methods. Subsurface DI (SDI) is also a localized irrigation method, but laterals are deployed underneath the soil surface, leading to a higher potential efficiency.Among other factors, water distribution in SDI is ...

Irrigation Regime for Protection on Root Intrusion for Subsurface Drip Irrigation

Journal of Biobased Materials and Bioenergy, 2021
Root intrusion into emitters poses a threat to the service lives of subsurface drip irrigation systems. In an attempt to address this problem, an experiment was conducted on spring wheat grown in soil columns installed in a greenhouse to study the effects of irrigation regimes in protecting against root intrusion into emitters.
