Foliar feeding through Mate Ranges

Fertilisers

Micronutrients involve in different vital

plant physiological activities.

Micronutrients can enhance plant

growth and stress tolerance.

They should be absorbed into the

plant and transported where they can

do their job.

Otherwise, deficiencies will appear.

Why Micronutrients …

Forms

Micronutrients come in many different forms that affect their solubility and

reaction (salts, oxides, chelates) in water and their uptake and usage by plants.

Foliar feeding

Fast way of getting nutrients into plants compared with soil application.

Especially important for the correction of nutrient deficiencies and the addition of micronutrients.

Chelation is a term that describes an encapsulation

process.

Chelates (chel”, meaning a crab’s claw in Greek) are

molecules with a neutral charge.

Benefits of Fulvic acids

FEATURES BENEFITS

Medium size complex organic molecules that readily penetrate plant tissue (no decomposing required)

Supports the growth of (feeds) beneficial micro-organisms

Readily taken up by plants by roots or leaves as carbon food, stimulating plant growth

Very water soluble Easy to use, compatible with all other chemicals (at suitable concentrations)

Binds to metals Gentle chelates metals and makes them mobile through leaf cuticle (improved foliar absorption)

Helps metal mobility within plant tissue (natural carrier)

Softens the effects of organic molecules and high ionic strengths solutions (reduces leaf burn)

One of the ingredients of Omnia’s mate ranges is Fulvate

When and where

• Any Foliar application to :- • improve plant responses• improve tank mix compatibility• reduce burning effects from ‘hot’ spray mixes

• May be used regularly in fertigation applications

Literature …(from reputable journals)Postbloom Humic- and Fulvic-based Zinc Sprays Can Improve Apple Zinc NutritionG.H. Neilsen, E.J. Hogue, D. Neilsen and P. Bowen

HortScience February 2005 vol. 40 no. 1 205-208

Zinc supplied as a fulvic-based Zn compound was absorbed and retranslocated to unsprayed new growth as effectively as zinc sulphate in apple seedlings of low Zn status grown hydroponically in the greenhouse. Similarly, fulvic- and humic-based compounds were as effective as zinc sulphate at improving short-term growth and Zn uptake into new tissues in Zn-deficient apple seedlings, with the best growth occurring at spray concentrations of Zn at 500 mg·L-1. Under field conditions, Zn concentration of peeled and washed `Jonagold' apples at harvest was increased, without phytotoxicity, by two or four postbloom sprays of fulvic Zn. It is therefore possible to use this material safely as an effective Zn-source after bloom.
