The smallest element on the periodic chart is a major component of all
biostimuiants and structural components of the plant such as carbohydrates,
amino acids and hormones. The hydrogen ion [H+] is also used by the plant to
drive certain membrane functions for proper nutrient absorption from the soil.
boron

B
10.811
B: Boron
Boron is deficient in most sandy soils but is needed in very small quantities
by the plant. It plays no role in enzymatic functions but is needed for sugar
transport, cell wall synthesis, lignification, and carbohydrate metabolism. Foliar
feeding is the most effective method for supplying boron to the plant.

N: Nitrogen
Plant tissue content of nitrogen is usually in the 4-5% range making it one of the
most needed supplemental nutrients. It is a major component of Chlorophyll,
amino acids, proteins and key biostimulants. It is very mobile within the plant
and the soil. Plants will take up and utilize nitrogen as nitrate (NO3), ammonium
(NH4) and urea (CO(NH2)2).

O: Oxygen
Oxygen plays many roles in plant function. It is a basic reactant for the
respiration reaction. The oxygen content in dry plant tissue can be over 40%.
Oxygen is a major component of the plant's carbohydrate and biostimulant load –
including sugars, cellulose, hemicellulose, proteins, hormones and many others.
Elemental oxygen is used by the plant as a free radical for stress response. The
plant absorbs dissolved O2 from the soil solution through the roots.

Mg

Mg: Magnesium
The primary and best known use of magnesium must interact with several
enzymes before it can be inserted into the chorophyll molecule. It also pays a big
role in protein synthesis and RNA function. Another important enzymatic function
of magnesium deals with the generation and use of ATP. Plants will readily use
both soil and foliar applications of magnesium compounds.

Si: Silicon
Silicon is the second most abundant element in the earth's crust but is one of
the most unavailable. However, it plays critical roles within the plant in structural
integrity, membrane operation, stress defense and cell division. It doesn't appear
to play any enzymatic roles and combines mainly as repeating units of (SiO).
Supplemental applications of both soil and foliar silicon are almost always recommended.

P

P: Phosphorus
The role of phosphorus in plant function is centred mainly in energy in the form
of ATP. It has others duties as a structural component of DNA and RNA and in
the metabolism of lipids. It is extremely reactive and will tie up readily in the soil
with calcium and micronutrients. Deficiencies of phosphorus result in slow and
inefficient growth. Foliar supplements are highly recommended for by-passing
the soil tie ups and ensuring proper phosphorus levels in the plant.

S: Sulfer
Sulfer exists in the soil, is absorbed by the roots and is stored in the plant as the
sulfate ion (SO4--) from. It is used in the production of amino acids, proteins,
antioxidants and enzymes. Sulfur deficiency results in slow, inefficient growth.
Shortages in the soil are infrequent and SO4 ties up readily with calcium.

K: Potassium
Tissue content of potassium is around 2.5% making it one of the most needed

maintaining proper stomata control, and facilitating photosynthesis and protein
building. It exists (within a plant) only as the K+ component of things such as
enzymes or cell walls. It is readily absorbed by the roots of the foliage.

CA: Calcium
Calcium is important for cell wall formation, cell division, and overall growth of
the plant, accomplishing these tasks as an elemental regulator. A particular
compound, calcium pectate, is crucial for a plant's response to stress from
mowing and pathogen attack. Most soils are high in stored calcium but low in
available calcium. This deficiency can be easily overcome by frequent liming and
foliar feeding of calcium compounds.
