Our Vast Experience

Who is Wallace Laboratories

Garn Wallace and Co-Founder Arthur Wallace are former staff members of University of California with over 600 publications concerning Soil Science, Plant Nutrition, Plant Physiology, and Heavy Metal Toxicity. We extend their university training and experience to your particular needs. We also offer the State of the Art recommendations.

Please, if you have any questions, please contact us and we’ll be glad to answer anything you ask!

Our Credentials

Wallace Labs provides analytical testing and consulting on soil, fertility, plant physiology, water quality, land restoration, salinity, toxicity, trace minerals, composts, amendments, soil conditioners and most related areas to plant growth, establishment of vegetation, erosion control and plant propagation.

The lab is located in Los Angeles County adjacent to LAX. Services are provided world-wide. The lab is equipped with simultaneous optical emission spectrophotometers, atomic adsorption, carbon/nitrogen/hydrogen/sulfur/oxygen instrument, microwave digester, and related instruments. It services federal, state, local, foreign governments, corporate and individuals.
