1974) stated that adequate fertilization with nitrogen, phosphorus, potassium, calcium, magnesium, manganese, boron, and iron was essential for normal plant growth and adequate yields of high-quality nutritious crops. Harris (1975) summarized that the principal effects of improvement of soils was to increase the yield rather than to enhance the nutritional quality of crop plants. Endemic goiter caused by a deficiency of iodine was probably the only evidence of the direct relationship between soil deficiency and malnutrition.

Green (1962) estimated that iodine deficiency caused endemic nontoxic goiter in all but 4% of the cases. Of this 4%, it could not be demonstrated that goitrogens in brassica vegetables were the major causal agents. Cauliflower and kale, among the crucifers, have high concentrations of thiocyanate. However, a daily intake of about 10 kg of cauliflower or kale would be required to furnish a goitrogenic concentration of thiocyanate in the blood. Nevertheless, according to Salunkhe et al. (1974), these thyrotoxic substances could be a matter of concern to food technologists in developing new or improved processing methods for reasons of economy, convenience, nutrition, flavor, or aesthetic appeal.
