For purposes of this subsection, location shall include a factory, warehouse, or establishment.
(2) Sampling and analysis shall be conducted in accordance with methods published by the AOAC International or in accordance with other generally recognized methods.
(3) The director, in determining for administrative purposes whether any product is deficient in plant nutrients, shall be guided solely by the official sample as defined in subdivision (11) of section 81-2,162.02 and obtained and analyzed as provided for in subsection (2) of this section.
(4) The results of official analysis of any official sample shall be forwarded by the director to the person named on the label when the official sample is not in compliance with the act or the rules and regulations adopted pursuant to the act.
