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 …

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.

Comparison Study Of Different Ionic Liquid Pretreatments In Maximizing Total Reducing Sugars Recovery, Kiat Moon Lee, Gek Cheng Ngoh Dr, Adeline Seak May Chua Dr, Li Wan Yoon, Teck Nam Ang Dr., Min Gyu Lee Prof

Teck Nam Ang Dr.

A process scheme combining the most suitable ionic liquid pretreatment, followed by solid acid and enzymatic saccharification was used to maximize the reducing sugars recovery from sago waste. Three types of ionic liquids, i.e. 1-butyl-3-methylimidazolium chloride ([BMIM]Cl), 1- ethyl-3-methylimidazolium acetate ([EMIM][OAc]) and 1-ethyl-3-methylimidazolium diethyl phosphate ([EMIM][(EtO)2PO2]) were evaluated based on their performance in terms of the total reducing sugars recovery, chemical cost, and pretreatment energy requirement. The results showed that all the ionic liquids assisted the saccharification processes by dissolving and depolymerizing the carbohydrates of the sago waste into shorter chain soluble oligosaccharides, as well as disrupting the biomass structure …


Infiltrometers For Restoration Site Evaluation, David A. Bainbridge Dec 2013

Infiltrometers For Restoration Site Evaluation, David A. Bainbridge

David A Bainbridge

Infiltration is a key factor in site disturbance and recovery as it determines soil moisture into the soil. Field evaluation can be done with an infiltrometer or sprinkling infiltrometer. Low cost field tested methods include: double ring, single ring and microsprinkler infiltrometers.
