Professional Soil Classifiers

Act 460 of 1975 of the State of Arkansas established the profession of Soil Classifying and provided for the regulation of the profession by the Arkansas State Board of Registration for Professional Soil Classifiers. The act established standards and requirements for licensing soil scientists and provided that a licensed soil scientist be in charge of all practice of soil science by a corporation, partnership, or sole proprietorship in Arkansas.

Act 691 of 2023 abolished the Arkansas State Board of Registration for Professional Soil Classifiers and transferred its authority to the Arkansas Natural Resources Commission.

The practice of soil science encompasses many activities related to environmental quality. These include investigating and evaluating the interactions among water, soil, nutrients, plants, and other living organisms. The preparation of assessments on subsurface ground absorption waste disposal systems, land application of municipal and industrial wastes, soil recommendation of residuals, soil erodibility and sedimentation, and identification of hydric soils are part of the definition of the practice of soil science. The performance of such activities is clearly related to the public welfare.

Each soil classifier-in-training not receiving their experience in the National Cooperative Soil Survey Program must prepare a training plan with their supervisor and submit it to the Natural Resources Division for approval prior to the beginning of the training period. At the end of the training period, the supervisor must submit signed documentation to support completion of the approved training plan including, but not limited to, training dates, training locations, and description of training. The supervisor must also submit a signed letter stating that the training is complete and that the trainee has received sufficient experience to apply for registration as a soil classifier.
