Section 611.10 - Standards, guidelines, and plans(a) NRCS conducts soil surveys under national standards and guidelines for naming, classifying, and interpreting soils and for disseminating soil survey information.(b) A soil survey Memorandum of Understanding (MOU) is prepared prior to the start of each soil survey project, or a work plan is prepared for soil survey maintenance activities. These documents provide specific details and technical specifications to support the interpretive and data needs of the area to be surveyed. The MOU is signed by representatives of NRCS, land grant universities, and in some States representatives of other State agencies. Federal land administering agencies also sign the MOU if federal lands are included in the survey.
