Leaching Of Accumulated Soil Salinity Under Drip Irrigation, Charles M. Burt, Brett Isbell

BioResource and Agricultural Engineering

Conducted a reclamation leaching experiment in a drip-irrigated pistachio orchard south of Huron, California, during the winter of 2002-2003. The study was conducted to quantify the leaching water required to remove salts from the effective root zone of trees. This experiment tested a new reclamation leaching technique: multiple lines of low-flow drip tape were used to apply water to the area of salinity accumulation along a tree row. This new technique allows water to be applied where there is salt accumulation along the tree row, as opposed to putting water on the entire area of the field. Since reclamation leaching …

Soil Salinity Accumulation In Orchards With Drip And Micro-Spray Irrigation In Arid Areas Of California, Charles M. Burt, Brett Isbell

BioResource and Agricultural Engineering

A soil salinity accumulation study was conducted by ITRC during the summer of 2002 to examine the long-term impact of drip and micro irrigation on salinity build-up in orchards, focusing on the salinity concentration pattern across a soil profile. This study assessed the current level of salinity accumulation in orchards irrigated with drip/micro systems and provided information to support recommendations on the most effective and efficient leaching techniques.

There is a concern that soil salinity accumulation in orchards, which comprise large acreages in the Central Valley of California, will eventually require reclamation leaching. Not only would this consume large quantities …

Reclamation Leaching For Salinity Buildup Under Drip/Micro Irrigation Of Trees, Charles M. Burt, Brett Isbell

BioResource and Agricultural Engineering

ITRC conducted a reclamation leaching experiment in a pistachio orchard in order to quantify the leaching water required to remove salts from the effective root zone of trees. This experiment tested a new reclamation leaching technique - multiple lines of low-flow drip tape were used to apply water to the area of salinity accumulation along a tree row.

Salinity Patterns: On Row Crops Under Subsurface Drip Irrigation (Sdi) On The Westside Of The San Joaquin Valley Of California, Charles M. Burt, Othman Al-Amoudi, Alejandro Paolini

BioResource and Agricultural Engineering

The objectives of this study were to identify if there was detrimental salinity buildup in the upper layers of soil caused by the usage of SDI on row crops, identify the extent of any detrimental salinity buildup, and identify successful and/or essential practices used by farmers who use SDI.

Soil Salinity Accumalation In Orchards With Drip And Micro-Spray Irrigation In Arid Areas Of California, Charles M. Burt, Brett Isbell

A soil salinity accumulation study was conducted to examine the long-term impact of drip and micro irrigation on salinity build-up in orchards, focusing on the salinity concentration pattern across a soil profile. The study assessed the current level of salinity accumulation in orchards irrigated with drip/micro systems and provided information to support recommendations on the most effective and efficient leaching techniques.

Long-Term Salinity Buildup On Drip/Micro Irrigated Trees In California, Charles M. Burt, Brett Isbell, Lisa Burt

BioResource and Agricultural Engineering

The Irrigation Training and Research Center (ITRC) of Cal Poly State University, San Luis Obispo, CA, hypothesized that there is salinity accumulation in the root zone of tree crops that have been irrigated with drip or micro-spray irrigation systems, located in arid and semi-arid regions. Therefore, a study was conducted by ITRC during the summer of 2002 to examine the long-term impact of drip and micro irrigation on salinity accumulation in orchards, focusing on the salinity concentration pattern across a soil profile. The project also provided information to support recommendations on the most effective and efficient leaching techniques.
