State Soil of Virginia

In 1999 the National Cooperative Soil Survey Program will have been in existence for 100 years. During the last 100 years, soils information has played a vital role in issues such as land-use planning, erosion control, increased crop yields, and protection of the environment and natural resources. Without soil, life as we know it could not exist! Without soil we could not grow crops to eat or feed livestock, grow lumber to build houses, play in sand at the beach, use soils to filter and dispose of our pollutants (drainfields, landfill), and the list continues.The Natural Resource Conservation Service (NRCS) of the United States Department of Agriculture (USDA) has asked that each state adopt, through legislation, a “State Soil.” This is one way the public will recognize the significance of soil in our lives. NRCS asked the Virginia Association of Professional Soil Scientists (VAPSS) to select a soil for Virginia. While Pamunkey has not been officially recognized by the legislature as the state soil, it is the soil that has been proposed.

Why Adopt a State Soil? In recognition of the 100 years that the Soil Survey program has provided valuable information necessary for planning growth and for protection of our natural resources and environment, each state in the Nation is adopting a “State Soil”. Soil is a basic resource that we rely on for most of our food, fiber and national economy.Fourteen other states have already adopted a State Soil by legislation or proclamation. There are twenty more including Virginia currently in the process of adopting a State Soil. Several years ago, Governor Allen tried to adopt Pamunkey as the State Soil by proclamation and found that it could not be accomplished using that means.In selecting a “State Soil” for Virginia, we were faced with dilemmas that many other states would not be faced with. Virginia covers some 450 miles along its southern boundary, five Physiographic Provinces and nine Major Land Resource Areas. With this kind of diversity in the state, it is hard to select a soil which represents the state as a whole.Fortunately, Virginia is also blessed with rivers whose watersheds cover each Physiographic Province as well as a history that is older than our Country. The James River crosses the entire State and brings sediments from each of the provinces it flows through. These sediments are deposited on flood plains and on deltas along its course to later form Pamunkey soils on low stream terraces.This soil, originally mapped as Wickham soil series, was first recognized in Hanover County. Chemical laboratory data revealed that the base saturation (natural fertility) was greater in these soils than is allowed in the Wickham series. The soil was named Pamunkey, the name chosen for a nearby river, which in turn was named for the Pamunkey Indian Nation that lives along the river.The Pamunkey soils were first used to sustain the Pamunkey Indians, and many other tribes, and later to grow crops by the settlers at Jamestown. The high natural fertility and high crop yields associated with these soils may be one reason that the Jamestown settlement survived. Pamunkey soils are prime agriculture soils in Virginia. Extensive areas of Pamunkey soils have been mapped in Hanover, Chesterfield, New Kent, Charles City, Surry, Henrico, James City, York, and other Tidewater counties.A soil profile of the Pamunkey soil, to be presented to the General Assembly, was taken from a soil pit which VAPSS members excavated under supervision of the National Park Service on Jamestown Island.

Facts about Pamunkey Soil Pamunkey soil is formed from sediments which originated in every physiographic province in the Commonwealth and therefore represents the WHOLE state better than most other soils.The farm where the representative profile of Pamunkey soil was excavated, near Jamestown, is the oldest continuously worked farm in the United States. In spite of encroaching development, this historic farm has been put into a conservancy program for the use of agriculture by the County of James City.The Pamunkey soil, on this oldest working farm in America, produced the world corn yield (308 bushels/acre) and the world record wheat yield (140 bushels/acre) in 2000.The first settlers at Jamestown grew their crops on Pamunkey soil which may be the very reason they survived. Prior to Jamestown being settled the River Indian Tribes, including the Pamunkey Tribe, recognized the high natural fertility of this soil. Its very likely Pocahontas saved Capt. John Smith’s life on this soil.

Soil Classification for Pamunkey Soil Pamunkey soils are  very deep, well drained soils formed in Piedmont and Coastal Plain fluvial sediments. They are on nearly level to sloping stream terraces. Slopes range from 0 to 15 percent. Mean annual precipitation is about 48 inches, and mean annual temperature is about 59 degrees F.  Pamunkey soils typically have a sandy loam surface layer and a sandy clay loam subsoil underlain by sandy and loamy substrata.Soil Classification: fine-loamy, mixed, semiactive, thermic Ultic Hapludalfs.

Constitution & Bylaws

PREAMBLE: Recognizing that soils are natural bodies on the earth’s surface, and that the utilization of this natural resource is of utmost importance to the Commonwealth, the Virginia Association of Professional Soil Scientists hereby declares that this organization further increase the dissemination of information concerning all phases of Soil Science in order to contribute to the general welfare of the Commonwealth.


The name of this organization shall be the VIRGINIA ASSOCIATION OF PROFESSIONAL SOIL SCIENTISTS.


The purposes of this Association are (1) to provide a forum for soil scientists, (2) to promote and enhance communication with other technical disciplines, and (3) to serve as a body of opinion on matters relating to Soil Science.Section 1: The objectives of this Association shall be the advancement of the profession of soil science. This shall be deemed to include the following:

  1. Promote the utilization and conservation of soils as a natural, non-renewable resource.

  2. Protect the public welfare by encouraging all qualified soil scientists to participate in the affairs of the Association.

  3. Advance the professional interests of soil science.

  4. Promote the liaison and exchange of information between soil scientists and other disciplines.

  5. Promote high standards of education and training in soil science

  6. Enhance public awareness and appreciation of the profession.

  7. Establish and maintain high standards of ethical conduct in all professional matters.



Section 1.0 Soils: Soil, as used in this text, is the collection of natural bodies of the earth’s surface, in places modified or even made by man of earth materials, containing living matter an supporting or capable of supporting plants out-of-doors, Its upper limit is air or shallow water, at its margins soil grades to deep water or to barren areas of rock or ice. Its lower limit to the not-soil beneath is perhaps the most difficult to define. Soil includes the horizons near the surface that differ from the underlying rock material as a result of interactions through time of climate, living organisms, parent materials, and relief. In the few places where it contains thin-cemented horizons that are impermeable to roots, soil is as deep as the deepest horizon. More commonly soil grades at its lower margin to hard rock or to earth materials virtually devoid or roots, animals or marks of other biological activity. The lower limit of soil, therefore, is normally the lower limit of biological activity, which generally coincides with the common rooting depth of native perennial plants[1].Section 2.0 A Professional Soil Scientist is a person who has acquired special knowledge of those physical, chemical, mineralogical and biological principles plus the experience necessary for their application to the profession of soil science. Experience is the effect of measured, observed, and inferred soil properties and their uses, and the conveyance of this information to others. It shall include the preparation of any soil information reports for public or private use.


Membership in the Organization shall be as established in the By-Laws. Membership divisions to meet the special needs of soil science disciplines are encouraged within the Virginia Association of Professional Soil Scientists. Each division shall be granted the authority and responsibility of establishing its own professional requirements upon approval by constitutional amendment.

The professional soil scientist should recognize such a standard, not in passive observance, but as a set of dynamic principles guiding her/his conduct and way of life. It is her/his duty to practice the profession according to these Cannons of Ethics.As the keystone of professional conduct is integrity, the professional soil scientist will discharge duties with fidelity to the public, employers, and clients, and with fairness and impartiality to all. It is her/his duty to interest oneself in public welfare and to be ready to apply her/his special knowledge for the benefit of mankind. She/He should uphold the honor and dignity of the profession and avoid association with any enterprise of questionable character. In her/his dealings with fellow professional soil scientists, she/he should be fair and tolerant.Professional LifeSECTION 1 The professional soil scientist will cooperate in improving the profession by exchanging information and experience with other professional soil scientists and students and contributing to the work of soil societies, associations and schools.SECTION 2 The professional soil scientist will avoid all conduct or practice likely to discredit or do injury to the dignity and honor of this profession.SECTION 3 As a professional soil scientist, service will be rendered to every human being without distinction of gender, race, religion, cultural background, economic or social condition.SECTION 4 The professional soil scientist will endeavor to extend public knowledge of soil science and will discourage the spreading of untrue, unfair and exaggerated statements regarding soil science.SECTION 5 The professional soil scientist will have due regard for safety of life and health of the public and employees who may be affected by the work for which she/he is responsible.SECTION 6 The professional soil scientist will express an opinion only when it is founded on adequate knowledge and honest conviction while she/he is serving as a witness before a court, commission or other tribunal.SECTION 7 It shall be considered unprofessional and inconsistent with honorable and dignified bearing for any professional soil scientist to advertise her/his work or merit in self-laudatory language, or in any other manner derogatory to the dignity of the profession, professional work and reputation. Solicitation by lobbying, criticism of competitors or self-laudation is degrading to the profession and is unethical. Advertising shall be limited to listing the name, address, telephone number and type of service rendered.SECTION 8 The professional soil scientist will not attempt to practice in any field of soil science in which she/he is not proficient.Relationships with Clients and EmployersSECTION 9 The professional soil scientist will act in professional matters for each client or employer as a faithful agent or trustee.SECTION 10 The professional soil scientist will engage or advise her/his client or employer to engage other experts and specialists whenever the client’s or employer’s interests are best served by such service.SECTION 11 The professional soil scientist will disclose no confidential information concerning the business affairs or technical information and data of clients or employers without their consent, unless required to do so by a court of law.SECTION 12 The professional soil scientist will not undertake work which she/he believes will not be successful without first advising her/his client of her/his opinion.Relationships with Other Soil ScientistsSECTION 13 The professional soil scientist will endeavor to protect the soil science profession, collectively and individually, from misrepresentation and misunderstanding.SECTION 14 The professional soil scientist will endeavor to provide opportunity for the professional development and advancement of soil scientists under her/his employment.SECTION 15 The professional soil scientist will not, directly or indirectly, injure the professional reputation, prospects, or practice of another soil scientist.SECTION 16 The professional soil scientist will not accept an appointment with a client or employer to replace another soil scientist while knowing that a just claim for compensation or damages of the previous soil scientist remains unpaid.SECTION 17 The professional soil scientist will not become responsibly associated with soil scientists who do not conform to ethical practices, with a corporation or partnership, as a cloak for unethical acts, but must accept responsibility for any such act to the extent of her/his authority.SECTION 18 The professional soil scientist will report to the Ethics Committee all violations of ethics.draft March 2012Attachment 2VIRGINIA ASSOCIATION OF PROFESSIONAL SOIL SCIENTISTSPROFESSIONAL WORK STANDARDSPurpose: To establish minimum work standards acceptable to the profession and the Virginia Association of Professional Soil Scientists.
