Personnel Profile

Dr. David Ruppert , Assistant Professor

Dr. David Ruppert

Coming to A&M-Kingsville from Washington, D.C., David Ruppert has traded the udults of the Nation's Capital for the ustalfs, usterts, xerids and ustolls of South Texas.  It's been a long journey starting in physics and ending in soils.  While primarily teaching high school physics and chemistry, the chance to teach an environmental science course left David impressed with the dependence of all living things on a functioning environment.  The discovery of soils as an object of study, as the necessary substrate for ecosystems, and as the seat of most ecosystem services makes David grateful for his career and excited to be a member of the A&M - Kingsville community.

Curriculum Vitae


B.S. in Physics, University of Dallas - 1992

M.S. in Physics, Dartmouth College - 1995

Ph.D. in Pedology and Nutrient Management, University of Maryland - 2012

Research Background and Interests

David's research background is diverse with undergraduate involvement in neutron scattering and plasma physics, and master's level work in the magnetosphere.  For his PhD, David got back down to earth studying the phosphorus retention and release behavior of ditch soils.  David's overall research interests are in the sustainable use of soil resources, the reversal of soil degradation, the building of soil quality, and the maximization of ecosystems functioning.  Specific research interests include the sustainable production of citrus, the closing of nutrient cycles between rural and urban areas, and the intersection of soil quality, production systems and nutrition among small-holder farmers.

Outreach and Community Service

While a student at the University of Maryland, David created the Great Oaks of Maryland in which several hundred seedlings of ecosystems-service-maximizing native tree species were (and still are) distributed to the public.  David enjoys meeting with prospective students, determining courses of study for undergraduate majors, and collaborating with graduate students.  David maintains active membership in the Soil Science Society of America, the American Society of Agronomy, the Crop Science Society of America, and the American Geophysical Union.
