WHAT IS FOLIAR FERTILIZTION AND WHY SHOULD DO I NEED IT?

Foliar Fertilization is the application of foliar sprays of one or more

mineral nutrients to plants to supplement traditional soil applications of fertilizers. Foliar feeding is a good, reliable method of feeding plants when ground application is not efficient enough. It has proved to be the fastest way of curing nutrient deficiencies and boosting plant performances at specific physiological stages. With plants competing with weeds, foliar spraying focuses the nutrient application on the

target plants.

Amino Plus Foliar fertilizer is a form of foliar fertilizer. It is 100% biodegradable and derived from

natural sources. It contains concentrated form of nutrient and can be diluted up to 13 mL/Liter of water.

It can be easily applied through common equipment for foliar feeding, i.e. spray, back pack sprayer, fan sprayer, etc.

 

Foliar application overcomes some disadvantages of soil fertilization like leaching, incompatibility of different nutrients in the soil, precipitation of insoluble fertilizer salts and fixation/absorption reactions of phosphorus and potassium (Fixation results in only about 10 to 30% of applied phosphate fertilizer being utilized by the crop in the first season, some may be utilized in subsequent years, but in progressively lesser amounts.)

Foliar feeding can also be used to overcome root problems when they are less effecient due to low/high temperatures, lack of oxygen in flooded fields, nematode attack damaging the vascular system, and a decrease in root activity during the reproductive stages where more of the photosynthetic creation is transferred for reproduction with less for root respiration

HOW IS FOLIAR FERTILIZER ABSORBED BY PLANTS?

In order for a foliar fertilizer nutrient to be utilized by the plant for

growth, it must enter into the leaf prior to entering the cytoplasm of a cell in the leaf. To achieve this the nutrient must effectively penetrate the outer cuticle and the wall of the underlying epidermal cell. Once penetration has occurred, nutrient absorption by the cell is similar to absorption by the roots.

THE LEAF CUTICLE

The leaf Cuticle is a thin covering on the outside of the leaf and

other organs which protects the plant from the extremes of the

environment. (It’s basically like the outermost layer of our skin). It consists of lipid and hydrocarbon polymers, impregnated with wax.

WAIT, WHAT?

Lipids, hydrocarbon polymer and wax, share common features: they are hydrophobic and lypophilic. (hydro = water , phobic: fear). THEY DON’T GET ALONG WELL WITH WATER. (lypo=fat, philia = love). Just as oil and water cant be together.

SO WHAT IS YOUR POINT TELLING ME ABOUT THIS TRAGIC STORY BETWEEN HYDROPHOBES AND WATER?

Of all the components of the pathway of foliar-applied nutrients, the cuticle offers the greatest resistance. Every foliar fertilizer out there shares a common challenge: they have to get through the hydrophobic layer that protects the outermost layer of the leaf.

Most fertilizers are in the form of salts, dissolved in water. And yes, you are right, its going to have a though time getting through the army of hydrophobes.

But as they say, if you cant beat them, join them. So the solution? A fertilizer that can join the water-haters-club. Thus, most foliar fertilizers add oil-based wetting agent (or surfactants) to increase adhesion of sprays to the leaf of the plants. With Amino Plus Foliar fertilizer, you do not need to buy another product to increase penetration of spray. It already contains natural wetting agents in a form of polyunsaturated fatty acids naturally present in fish.

The natural, low temperature process of Amino Plus Fertilizer retains the valuable oils from fish: Omega 3 oil. Omega 3 oil is highly penetrative, helping to push foliar nutrients to the plants. It overcomes the waxy surface of the plant by forming a thin surface film to spread the spray evenly.

 

SO IS FOLIAR FERTILIZATION THE HOLY GRAIL OF PLANT NUTRITION?

Im sorry to disappoint you, but No. As emphasized earlier (obviously because its written in bold letter), foliar fertilizers supplement traditional soil applications. There never exists a product that offers all-in-one solution for plants nutrition. It is all about balance, and knowing what your plant needs. Foliar fertilization has the advantage of quick response to nutrient deficiency but does not replace the long-term advantage offered by a healthy soil.

Amino Plus Bio-fish fertilizer can also be applied to soil. It contains beneficial microorganisms that helps promote the biological balance in the soil.

 

I WANT TO GIVE MY PLANTS MAXIMUM SUPPLEMENTATION, AND CAN I FOLIAR-FEED AS MUCH AS I WANT?

No. The advantage of foliar fertilization does not excuse you for a foliar feeding frenzy. High concentrations of foliar fertilizer can cause leaf burns. It gets worse by applying fertilizers during intense sunlight. (Remember foliar fertilizers are oil-based and not water-based: water plus heat creates water vapor, but oil plus heat fries your chicken)
