Missouri Revised Statutes Title XVII. Agriculture and Animals § 266.530. Samples, how taken, number required

1. Samples of agricultural liming materials within the meaning of the act shall be obtained by taking the sample from the producer's production belt as the material is being produced or from stockpile. Sampling of stockpiles may be made when there is a stockpile having no certification of the calcium carbonate equivalent, magnesium content, fineness, effective neutralizing material, and effective magnesium as herein provided. A total of eight or more samples shall be taken at locations where there are permanent fixed plants during the year in which agricultural liming materials are being produced or distributed but not more than one official sample per day may be taken from each individual stockpile or production belt.

2. Samples shall be taken at locations where there is no permanent fixed plant during the month that a portable plant is at a given location until a total of eight or more samples are accumulated for a fiscal or calendar year from either production plant or stockpile.

3. Samples shall be taken of agricultural liming materials until a total of three representative samples have been accumulated and submitted for analysis to determine an average after which a sample shall be obtained and tested with the average recalculated for guaranteed analysis by dropping the analysis of the oldest sample and using the analysis of the most recently taken sample to establish a new average.

4. Samples for analysis may be taken from the production belt by the producer or distributor or authorized representative in the presence of a person appointed by the director. Samples from stockpiles for analyses shall be taken only by persons authorized and appointed by the director upon prior notification of the producer or distributor involved. Samples may be taken from trucks and at other points but will not be used in computing the average for purposes of the guaranteed analyses at source of production or stockpile.

5. Producers or distributors of agricultural liming materials shall notify the director, or persons appointed or authorized by him, of the production or distribution of agricultural liming materials so that samples may be taken in compliance with this section.

6. All samples for analysis shall be taken according to official sieve analysis of agricultural liming materials methods as set forth in the regulations.
