Micronutrient Facts:



Micro nutrient Facts:

Manganese (Mn)
Manganese is essential to plants but too much is toxic. Manganese functions in chlorophyll development & serves as a catalyst in several enzyme systems in the oxidation-reduction process. Manganese deficiencies are very similar to iron deficiencies & appears in the younger leaves of the plant first. Colour may be pale between the veins of broadleaf plants.
Boron (B)
Boron is vital to the growth & development of the plant. Without adequate Boron, new growth ceases. It is necessary in the pollination & seed production stages. Boron is essential for maintaining a balance between sugars & starches. A small amount of Boron is beneficial to plants but too much can be toxic to plants.
Copper (Cu)
Copper is important as a co-enzyme. It is needed to activate several plant enzymes, including building & converting amino acids to proteins. Since Copper is an immobile nutrient, deficiency symptoms usually occur on new growth. Copper deficient plants will become chlorotic &take on a bleached appearance. New growth may die.
Zinc (Zn)
Zinc is necessary for starch formation and proper root development. It is also essential for seed formation & maturity. The most common nutrient deficiencies include interveinal chlorosis on older leaves with shortening of the intermodal area. This shortening often leaves a short compressed plant with a rosetted appearance.
Molybdenum (Mo)
Molybdenum is required by plants for utilization of nitrogen. Plants cannot transform nitrate nitrogen into amino acids. Without molybdenum legumes cannot symbiotically fix atmospheric nitrogen.*
Iron (Fe)
Iron is required for the formation of chlorophyll in plant cells. It serves as an activator for biochemical processes such as respiration, photo-synthesis and symbiotic nitrogen fixation.*
Magnesium (Mg)
Magnesium is the key element in the molecule of chlorophyll. It regulates the uptake of other nutrients in the plant and acts as a carrier of phosphorous in the plant. Deficiencies usually occur in sandy soils or in soils with extremely high pH. Magnesium deficiencies cause corn plants to develop light yellow or white appearance between the parallel veins.
Calcium (Ca)
A secondary element in plant nutrition, calcium is needed in the plant to promote early root formation and growth. Improves general plant vigor and stiffness of stalk. With Calcium deficiencies, leaves have a wrinkled or crinkled appearance and in some instances, young leaves may never unfold. Roots are also short and are very bunched.
