Increases in crop yields from application of B, Cu, Fe, Mn, Mo, and/or Zn occur in many parts of the world including numerous regions of the USA. There is growing awareness that micronutrient deficiencies may limit crop yields even though exceedingly small amounts are required by plants (Table 15-1). Various reasons can be provided to account for the current increased recognition of micronutrient needs in crop production. These include (i) improved soil test and tissue analysis methods for diagnosis of micronutrient deficiencies; (ii) accumulated data on crop responses to micronutrient applications on diverse soil types; (iii) micronutrient removal from long-term crop production; (iv) increased use of high-analysis fertilizers with low amounts of micronutrient impurities; (v) higher micronutrient requirements accompanying higher crop yields; (vi) less use of animal manures in crop production; and (vii) induction of micronutrient deficiencies by high P concentrations from long-term applications (Berger, 1962; Vitosh et al., 1981). Attention will be directed in this chapter toward correction of B, Cu, Fe, Mn, Mo, and Zn deficiencies in plants grown under diverse management regimes. Literature on Cl, Co, and Ni deficiencies also will be discussed.
