Ninety-two samples of complete fertilizers showed a deficiency in one or more elements of plant food out of a total of 1,741 samples analyzed, or considerably less than six per cent. This shows excellent chemical control on the part of the fertilizer manufacturers.

0f the 335 complete commercial feed samples, 90 were deficient in one or more of the guaranteed constituents. Twenty-nine samples were deficient in protein. Sixteen samples were deficient in fat. Fifty-seven samples were deficient in nitrogen-free extract (of this number, eighteen were deficient by reason of the fact that protein and fat exceeded the guaranteed analyses). Twenty-nine samples were excessive in fiber.
