The University of Delaware Soil Testing Laboratory was established in 1947 to provide a rapid, accurate soil analysis service to Delaware farmers. Prior to that time, soil testing was performed by individual agronomists to obtain research data or to assist in the diagnosis of problems in the field for growers. The opening of the laboratory coincided with a serious effort by agronomists both locally and across the nation to promote the proper use of lime and fertilizer to maintain and improve the fertility of soils and to maximize crop yields.
The Soil Testing Laboratory has changed dramatically since those early years. Initially, the laboratory relied on graduate students for labor and faculty laboratories for facilities. Today, the laboratory has evolved into a full scale, self contained program that employs four full-time staff and one half-time secretary as well as additional seasonal help as needed. The modern UD Soil Testing Program occupies two laboratories in Worrilow Hall on the College of Agriculture and Natural Resource campus in Newark and is equipped with modern, state of the art equipment and analytical instrumentation. The program and its staff participate in numerous regional and national organizations associated with soil testing, soil science and agriculture including the USDA Northeast Coordinating Committee for Soil Testing (NEC-1007), the Mid-Atlantic Soil Testing and Plant Analysis Work Group, the North American Proficiency Testing Program, the Soil and Plant Analysis Council, the American Society of Agronomy and the Soil Science Society of America. Such participation is critical to remaining at the leading edge of soil testing services.
