Randall P J and Bouma D 1973 Zinc deficiency, carbonic anhydrase and photosynthesis in leaves of spinach. 32, 433–442. Zinc deficiency occurs when plant growth is limited because the plant cannot take up sufficient quantities of this essential micronutrient from its growing medium. This service is more advanced with JavaScript available, Zinc in Soils and Plants Walker C D and Welch R M 1987 Low molecular weight complexes of zinc and other trace metals in lettuce leaf. As a component of proteins, zinc acts as a functional, structural, or regulatory cofactor of a large number of enzymes. Thus, Zn deficiencies affect plant color and turgor. Agron. Absorption and Function of Zinc in Plants Zinc is taken up predominantly as a divalent cation (Zn 2+), but at high pH it is probably absorbed as a monovalent cation (ZnOH +) .Zinc is either bound to organic acids during long distance transport in the xylem or may move as free divalent cations. Agr. In addition, once visual symptoms appear, yield loss has already occurred. The cost to the farmer, associated with loss of production, is by far higher than the cost of testing the soil and plant tissue and applying zinc fertilizers. Plants differ in their need for micronutrients, and we will focus here only on those elements that are generally accepted as essential for all higher plants: boron (B), chloride (Cl), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), nickel (Ni), and zinc (Zn). Exp. Plant. Sommer A L and Lipman C B 1926 Evidence on the indispensible nature of zinc and boron for higher green plant.

It is needed by plants in small amounts, but yet crucial to plant development. 73, 132–186. Am. Plants require zinc in small but critical concentrations for several key actions, including: membrane function, photosynthesis, protein synthesis, phytohormone synthesis (e.g. Zinc is either bound to organic acids during long distance transport in the xylem or may move as free divalent cations.
