ROLE OF MICRONUTRIENTS

ROLE OF MICRONUTRIENTS

All 21 nutrients required by the plant, including Macronutrients, Micronutrients, and Secondary Nutrients must be in BALANCE in order for the plant to maintain it’s utmost HEALTH to defend against un-favorable environmental conditions.
A proper Soil and Tissue Sampling program is key tool in managing plant nutrition.

KEEP IN MIND THAT PHOSPHORUS IS THE “ WORK HORSE “ IN THE PLANT.
Phosphorus moves EVERY NUTRIENT up & down the plant daily.


WHY USE ALPINE ?

Even though micronutrients are required in minute quantities, they are essential for healthy plant growth & profitable crop production. ALPINE micronutrients provide an economical source for correcting nutrient deficiencies & improving plant health. ALPINE micronutrients are fully chelated & can be used in both foliar & soil applied applications.

 

BORON (B)

SUGAR MOVER
Boron moves plant sugars up and down the plant daily. During the night time, Boron moves plant sugars from the plant to feed the root system, which in turn feeds the soil biology. During night, the soil biology exudes food for the roots and then Boron moves this food from the roots up into the plant during the day. This process takes place daily.
CELL DEVELOPMENT
Boron functions in plants in the differentiation of meristematic cells. Without Boron, cells may continue to divide, but structural components are not differentiated. Missing florets (seeds) in timothy and alfalfa heads. Larger cereal heads and fuller Canola & legume pods. Now let shave a look at why there can be missing seeds in canola pods.
MISSING SEEDS
At the top and the bottom of the pod is a hormone called GABA. This hormone must move in the pod to fertilize each and every seed in that pod. No GABA no SEED. The nutrient that moves GABA throughout the pod is Boron along with mainly Phosphorus, Manganese, Calcium and other nutrients. Remember BORON along with Phosphorus moves SUGARS in the plant daily, so if there is an interruption of this or a lack of nutrients - the SEED DOES NOT BECOME FERTILIZED SO THEREFORE NO SEED.

MANGANESE (MN)

THE ELEMENT OF LIFE
NO MANGANESE = NO LIFE. Mn assists Iron in Chlorophyll production. Mn affects lignin building qualities and is critical in preventing lodging & disease. Mn is crucial when growing oats. Glyphosate has been linked to Mn deficiencies With glyphosate translocating within the root mass of weeds and RR crops thus leaking into the root rhizosphere. This can immobilize Mn which is required for the growth of many plants.
Manganese is not available when soils are cold in spring because Mn starts out in the Mn4+ state, must convert to the Mn3+ state and then convert to the Mn2+ state to be available to the plant. The fungus “ Take-all ” root rot oxidizes early Mn availability, reducing lignification of roots, making them more susceptible to infections. This is where a GREAT SEED TREATMENT WORKS. Low pollen fertility and reduced 1000 kernel or bushel weight are symptoms of Manganese deficient crops. Foliar, Seed Placed or Seed Treated with Manganese are ways to correct Mn deficiencies but Seed Treated and Seed placed treatments are preferable. Like ALPINE’S new ASN.

 

COPPER (CU)

PLANT DISEASE PREVENTION
Cu is important in plant disease prevention. - Plant Diseases - i.e.: Net Blotch, Ergot and Pig Tailing. Cu affects lignin building qualities and is crucial in preventing lodging. Cu greatly affects kernel size and kernel weight. Cu and other micro deficiencies are enhanced by too much up-front NITROGEN early in spring. The window of opportunity to correct a Copper deficiency lasts until just before heading.


DEFINITIONS


Lignin
 - A polymer found extensively in the cell walls of all woody plants. It combines with hemicellulose materials to help bind the cells together and direct water flow.
Lignification - A change in the character of a cell wall, by which it becomes harder. It is supposed to be due to an incrustation of lignin.
Chelate - A chelate is a complex organic molecule that surrounds the nutrient ion. Chelates are used as carriers for micronutrients, to keep them in solution & protect them from reactions that cause the micronutrient to become insoluble and unavailable to the plant.

ZINC (ZN)

FLOWER FORMTION
Zinc is crucial in flower formation. i.e. Canola. Zinc acts like “Antifreeze” in the plant to give early and late frost protection. Zinc controls the synthesis of many plant growth regulators. Animals deficient in Zinc require twice as much feed to attain the same weight. Zinc is unavailable in high pH soils. Zinc improves germination rate and plant vigor.

MOLYBDENUM (MO)

PLANT NODULATIONThe most misunderstood micronutrient, but one of the most important. Without Moly – plants cannot transform nitrogen into amino acids and legumes cannot symbiotically fix atmospheric NITROGEN. Moly is very important for plant nodulation (Peas, Beans, Alfalfa).

IRON (FE)

CHLOROPHYLL FORMATION
Iron is required for the formation of chlorophyll in the plant. Iron is essential for plant respiration, photo-synthesis and symbiotic nitrogen fixation. Iron along with Molybdenum help plants fix atmospheric NITROGEN out of the air. Also keep in mind that the air is 78% Nitrogen & all plants can fix Nitrogen out of the air. Most soils in Western Canada are sufficient in iron.

MAGNESIUM (MG)

CHLOROPHYLL MAKER
Magnesium is the center of the chlorophyll molecule. Magnesium along with Manganese and Iron are the chlorophyll makers in the plant. These 3 nutrients make the plant green. Most Western Canadian soils are abundant in Magnesium and plant uptake is usually good.

SULPHER (S)

PROTEIN SYNTHESIS
Sulpher is made up of three amino acids and essential for protein synthesis. Sulpher is a leachable and mobile nutrient. It can be the most variable nutrient within fields in Western Canada. Sulpher deficiencies can be identified with yellowing of the newer leaves in cereals and purpling in canola.
