Abstract
A summary of four micronutrient surveys conducted between the years 1961 and 1967 revealed that one or more of the six micronutrient elements are recommended in every state. Micronutrient recommendations may be found for all the major field, forage, vegetable, fruit and nut crops grown in the United States. Forty‐three .states recognize and make recommendations for B, 16 for Cu, 23 for Fe, 31 for Mn, 24 for Mo and 39 for Zn. Most of the recognized micronutrient deficiencies occur in specific areas and on specific crops. Cu seems to be the only micronutrient for which this is not true. The tonnage of all micronutrient fertilizers sold in 1968 represents only 0.25% of the total NPK tonnage, although its dollar value is about 2% of total dollar value of all NPK fertilizers sold.Keywords
