Manganese is generally required with zinc in foliar spraying of commercial citrus. Other crops may show deficiencies induced by high levels of iron, copper, zinc, calcium or magnesium.

Zinc controls the synthesis of indoleacetic acid, an important plant growth regulator that promotes cell division, directs the flow of food and other plant auxins. Zinc promotes growth hormones, starch formation and seed development/maturation. Terminal growth areas are affected first when zinc is deficient. Deficiency is most common in sandy and alkaline soils (high pH) or soils with low organic matter content that are high in available phosphorus.
Mn is essential in the “Hill” reaction of photosynthesis – the splitting of water to yield 4e- and O2
H20 + A + light -> O2 + H2A
Copper serves as an activator of numerous plant enzymes and plays a role in the development of plant pigments. Copper deficiency interferes with protein synthesis and has been observed on trees and vines growing on organic soils and sandy soils. Copper deficiency may be associated with high phosphorus, zinc or nitrogen levels. Foliar diseases are increased, and lignification is reduced or absent, with copper deficiency.
