About the founder


Founder/Soil Scientist

Dr. Rita Abi Ghanem holds a Ph.D. in Soil Science from Washington State University with an emphasis in soil microbiology and sustainable agriculture. Her career focus aimed at developing more sustainable agricultural management practices to produce higher quality food while protecting the environment.

Dr. Rita Abi-Ghanem has extensive experience in humic acids and soil health. She previously led a team developing and testing carbon-based soil and plant liquid-nutrition products and coordinated with scientists in the United States and worldwide to set up research projects to test the efficiency of the products. She also built an advanced soil fertility and chemistry laboratory and hired a team of scientists.

Dr. Abi-Ghanem was a member of the Humic Products Trade Association Science Committee, the Fluid Fertilizer Foundation Research and Education Committee, and a member of the Agricultural Science Committee of the U.S. Environmental Protection Agency’s (EPA’s) Science Advisory Board (SAB) and the Science Communication Editor of the Soil Science Society of America Journal.

Among the projects on which Dr. Abi-Ghanem has collaborated internationally are the United Nations- Biodiversity Program — for which she evaluated foliar and seed-borne diseases on wheat and barley landraces in Lebanon — and the Bill and Melinda Gates Foundation Agricultural Research Connections (ARC) workshop during the summer of 2013 in Kenya for improving soil-plant-microbe interactions and natural nitrogen supplies. She has provided education to Iraqi scientists in agricultural methods and soil ecology through sessions held in Egypt, Syria, and Jordan. Dr. Abi Ghanem also served as an executive board member of the Association of International Agriculture and Rural Development (AIARD) headquartered in Washington DC and has extensive experience working worldwide.

I have known Dr. Rita Abi-Ghanem since 2009 when I was affiliated with the U.S.-based Association for International Agriculture and Rural Development, and she was as selected as one of our Future Leaders from a very competitive group of outstanding young professionals. That designation as a Future Leader certainly was prescient — since that time she has proven to be an outstanding soil scientist, plant pathologist, and science enterprise manager, and has been duly recognized as a leader in her field. She is delightful to work with, highly qualified and experienced, and a dedicated service-oriented professional who I would highly recommend.

Dr. Abi-Ghanem shares her incredible depth of knowledge using a clear, interactive approach that brings to life the important world of soil health.

Allan Hancock College

I have known Dr. Rita Abi-Ghanem since she was in graduate school at Washington State University. We worked together on several international research and extension projects in Egypt, Syria and Jordan. Rita not only worked with teams from WSU International Programs on these projects but led many. Probably the most impactful project she led was with a team of WSU women faculty training Iraqi women extension agents. I look forward to working with her in the future and watching AG Consultant Services grow.
