Mitigation Site Soil Characteristics And The Effects Of Inoculation, Nursery Fertilizer Practices And Irrigation On Survival And Growth Of Mesquite (Prosopis Glandulosa) In The Coachella Valley, California, David A. Bainbridge, Marcelle M. Darby Jul 2014

Mitigation Site Soil Characteristics And The Effects Of Inoculation, Nursery Fertilizer Practices And Irrigation On Survival And Growth Of Mesquite (Prosopis Glandulosa) In The Coachella Valley, California, David A. Bainbridge, Marcelle M. Darby

David A Bainbridge

Prosopis glandulosa var. torreyana (mesquite, honey mesquite) is a small to medium sized leguminous tree that was once common in the low desert of California. Widespread destruction of mesquite woodlands in the Coachella Valley of southern California for fuel wood, agricultural and urban development, and urbanization has reduced once vast stands to isolated remnants. The rerouting and widening of Highway 86 in the Coachella Valley was a typical example of ongoing mesquite woodland removal. Despite the recognized need for mitigation, relatively little information on mesquite establishment in California is available. This research explored mesquite establishment by replanting on an abandoned …


Soil Penetrometer, David A. Bainbridge Jan 2014

Soil Penetrometer, David A. Bainbridge

David A Bainbridge

A simple easy to build impact soil penetrometer can provide very useful information on soil strength. This can be very important for restoration planning and management of soils in agriculture and forestry.


Soil Solarization, David A. Bainbridge Jan 2014

Soil Solarization, David A. Bainbridge

David A Bainbridge

Soil solarization makes use of the energy of the sun to heat soil and kill weeds and pathogens. Single, double, or bubblepack plastic and be used to increase soil temperature. Multiple growth benefits are often realized.


Deep Pipe Irrigation, David A. Bainbridge Jan 2013

Deep Pipe Irrigation, David A. Bainbridge

David A Bainbridge

Deep pipe irrigation uses a vertically placed section of pipe to deliver water to the roots of plants. This reduces evaporation and increases water use efficiency. Deep pipes can be filled by hand, drip or rainwater catchment.


Planting Desert Sites, David A. Bainbridge Jan 2013

Planting Desert Sites, David A. Bainbridge

David A Bainbridge

Desert planting requires great care in preparing plants, handling plants and planting. With proper consideration of soil, climate and water availability plants can be established despite severe conditions of high temperatures, high winds, herbivory and lack of water.


Site Assessment For Environmental Restoration, David A. Bainbridge Jan 2013

Site Assessment For Environmental Restoration, David A. Bainbridge

David A Bainbridge

Restoring degraded desert ecosystems is challenging but it can be done. The first key step is understanding the site history and understanding the disturbance and current site conditions. With this information the appropriate steps can be taken to improve the site ecosystem function and structure.


Container Plants For Desert Restoration, David A. Bainbridge Jan 2013

Container Plants For Desert Restoration, David A. Bainbridge

David A Bainbridge

Container planting is essential for most desert restoration work because direct seeding is rarely successful. The containers best suited for desert planting are often taller (deeper) to facilitate root development. Fertilizer management, inoculation, irrigation and pruning can be used to maximize root growth with minimal shoot development.


Buried Clay Pipe Irrigation, David A. Bainbridge Dec 2012

Buried Clay Pipe Irrigation, David A. Bainbridge

David A Bainbridge

The buried clay pipe method of irrigation is one of the most efficient systems known and is ideal for gardeners and small farmers. Buried clay pipe irrigation uses a buried, unglazed clay pipe filled with water to provide controlled irrigation to plants as the water seeps out through the clay wall at a rate that is influenced by the plant's water use. It has been used for more than one hundred years.This auto-regulation leads to very high efficiency--considerably better than drip irrigation and many times better than conventional surface irrigation. This also reduces weeds, increases yields, and can speed maturity …


Super Efficient Irrigation With Buried Clay Pots, David A. Bainbridge Jan 2012

Super Efficient Irrigation With Buried Clay Pots, David A. Bainbridge

David A Bainbridge

Buried clay pot irrigation was first described in an agricultural extension bulletin in China more than 2000 years ago. The clay pot provides demand responsive irrigation at very high efficiency. Clay pot irrigation can be 5-10 times more efficient than conventional irrigation. It is being used more widely in Asia, Africa, Latin American and the US.


Buried Clay Pot Irrigation, David A. Bainbridge Jan 2011

Buried Clay Pot Irrigation, David A. Bainbridge

David A Bainbridge

Buried clay pot irrigation was first described in Chinese texts from more than 2000 years ago. It uses a porous clay pot to provide demand responsive irrigation. Efficiency is often 3-10 times conventional surface irrigation.


Alternative "More Efficient" Irrigation Systems, David A. Bainbridge Jan 2010

Alternative "More Efficient" Irrigation Systems, David A. Bainbridge

David A Bainbridge

Many traditional irrigation systems work well for ecological restoration projects. These demand responsive systems are very water efficient and robust and have proved themselves in the most extreme desert conditions.

Ecocomposite Materials, David A. Bainbridge

David A Bainbridge

Ecocomposite materials combine fibers, resins and natural materials for added strength and durability. These materials can be fully and easily recycled by nature.


Soil Treatment For Restoration Projects, David A. Bainbridge Jan 1999

Soil Treatment For Restoration Projects, David A. Bainbridge

David A Bainbridge

Soil treatment is a critical step in restoration projects. When soil problems are ignored restoration projects fail. Erosion, compaction, limited infiltration and other problems can make a site very different from its historic function and structure. Treatment can be done with equipment or by hand and will greatly improve chances for success.


Forest Gardens Of The Maya, David A. Bainbridge Jan 1988

Forest Gardens Of The Maya, David A. Bainbridge

David A Bainbridge

The lowland Maya supported very high populations in an area with limited water and soil. Much can be learned from studying their sophisticated management practices. Forest gardens and agroforestry helped provide key nutrients, materials, and inputs for improved soil.


Use Of Acorns For Food In California: Past, Present, Future, David A. Bainbridge Jan 1987

Use Of Acorns For Food In California: Past, Present, Future, David A. Bainbridge

David A Bainbridge

Acorns are a neglected food for people, livestock, domestic fowl, and wildlife in California. Acorns are easy to collect, store, and process. In addition to the nutritious nut and meal, acorns yield an oil comparable in quality and flavor with olive oil. The existing acorn market could be greatly expanded and provide new income for rural people. A serious effort to identify and propagate the best oak acorn cultivars for these products is long overdue. It is particularly appropriate for this research to be done in California, which once had an acorn based economy.
