Abstract

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.
