Crude Chile nitrate, raw rock phosphate, and limestone rocks may contain enough iodine to influence the iodine content of forage crops and vegetables when applied in adequate amounts to soils deficient in iodine. 2. Plants may absorb relatively large amounts of iodine without producing any signs of toxicity. 3. It is a simple matter to increase the iodine content of forage crops and vegetables by adding appropriate amounts of potassium iodine to the soil in which they are grown. 4. Tests by dialyses and the separation of various protein fractions of a sample of corn that contained a relatively large amount of iodine showed that this element was present in organic combinations and therefore in suitable form for assimilation by livestock and man.
