Micronutrients & Enzymes
One of the most important components of any fertilizer program is the
MICRONUTRIENTS!
The Micronutrients Most Discussed
Average Quantities of Micronutrients in Soil
Elements Recognized in Plant Nutrition
Micronutrient Availability Related to pH
Enzymes
Enzymes are just protein clusters until activated by a specific metal ion!
Less Energy is Required if Enzymes are Available.
Enzymes lower the activation energy for biochemical processes.
Plant Metabolic Cycle
Photosynthesis: CO2 plus H2O sugars amino acids protein, the building blocks of living tissue.
All require Enzymes.
Some Enzymes & Required Metal Ions
Phospholipase manganese, MnAuxin enzyme zinc, ZnCytochrome iron, FeGlutamic dehydrogenase copper, CuStarch phosphorylase boron, BNitrate reductase
molybdenum, Mo
Making of Phospholipids
Some Functions of Enzymes
Phospholipase (Mn) Controls the synthesis of
phospholipids formation. Auxin enzyme (Zn)
Growth ordering and regulator.
Refines tryptophane into raw auxin or indoleacetic acid.
Cytochrome (Fe) The electron carrier in
oxidation. Facilitates the ADP-ATP
process in the Krebs Cycle. Enzyme transport.
Glutamic dehydrogenase(Cu)
Chlorophyll formation Formation of protein & some
amino acids Starch phosphorylase(B)
Starch formation –phosphate sugar bond
Nitrate reductase(Mo) Reduces nitrate to
ammonium ion, allows amino acid production.
