NAC587.190. Samples: Quantity and size.

     1. Bulk seeds or screenings must be sampled by inserting a long probe or thrusting the hand into the bulk as circumstances require in at least seven uniformly distributed parts of the quantity being sampled. At least as many trierfuls or handfuls must be taken as the minimum which would be required for the same quantity of seed or screenings in bags of a size customarily used for such seed or screenings.

     2. For lots of six bags or less, each bag must be sampled. A total of at least five trierfuls must be taken.

     3. For lots of more than six bags, five bags plus at least 10 percent of the number of bags in the lots must be sampled. (Round off numbers with decimals to the nearest whole number raising 0.5 to the next whole number.) Regardless of the lot size, it is not necessary that more than 30 bags be sampled.

     4. Samples must be drawn from previously unopened bags except under circumstances where the identity of the seed has been preserved.

     5. In sampling seed in small containers, it is not practical to sample as required in subsection 2. A portion of one previously unopened container or one or more entire unopened containers may be taken to supply a minimum sample as required in subsection 6.

     6. The following are minimum sizes of samples of agricultural seed, vegetable seed and screenings to be submitted for analysis, test or examination:

     (a) Two ounces of grass seed not otherwise mentioned, white or alsike clover or seeds not larger than these.

     (b) Five ounces of red or crimson clover, alfalfa, lespedeza, ryegrass, bromegrass, millet, flax, rape or seeds of similar size.

     (c) One pound of sudangrass sorghum proso hemp or seeds of similar size.

     (d) Two pounds of cereals, vetch or seeds of similar or larger size.

     (e) Two quarts of screenings.

     (f) Vegetable seed samples shall consist of at least 400 seeds.
