Fertilization ( Macro & Micro elements )

Fertilization (Macro & Micro)

1.Macro N (Nitrogen)
In the Vase vegetative N elements who need a lot more to the formation of protein that is required

in cells formation, tissues and organs. N elements is divided into two: ammonium nitrate, NO3-and

NH4 + ( third form of urea is used as organic fertilizer by the presence of carbon and

microorganisms modified enzyme urease into ammonia)
When the plants were given ammonium, it will be absorbed very quickly ... because of the small

cation. Therefore, the protein rapidly formed and there was a giant cells (fast growing plants) and

the cell wall would be vurnerable. This should be a concern,cos plants will be susceptible to

mycelial fungi and when the humidity falls below 50% will quickly wither.
If given nitrate, absorbed more slowly because they have passed the stage .. amonification.Cells

generated will be more compact and dense and therefore contributes to plant resistance, and

subsequent gains in terms of faster generative vase  ... flowers appear straighter, brighter colors

.

2.Macro P (phosphorus)
Phosphor binding of solar energy in the process of photosynthesis ... the process of hydrate who

used for proteins formation.
The provision will give effect: Rooting growing rapidly and many. When the ratio of increase will

trigger a transition Vase, Vase vegetative to generative.

3.Macro K (potassium, potassium)
function as a regulator of MLP process of photosynthesis, turgor pressure, and protein synthesis.
Granting the elements of K increased in accordance with the rate of plant growth, blooming size in

the Vase needs can achieve a number of N:K=1:2. if the element K is excessive it will arise

antagonism of Ca and Mg, who will result of Ca and Mg deficiency symptoms.

4.Macro Ca (Calcium)
Enhance the resilience of Ca function, cell wall and take a role in cell division so that cells

formed in good quality.
When Ca deficiency often have malformations or other forms of plants that are not normal.In

fertilizer market afloat, usually containing less Ca ... and there is little concern if the Ca met

sulfate & phosphat  will precipitate potassium sulfate-potassium phosphat Both can not be absorbed

by the roots, so that the deficiency symptoms of Ca, S, and P. To overcome it need fertilizer mix

of A-B.

5. Macro Mg (magnesium)
Magnesium is a core element of chlorophyll, a very important role in photosynthesis.Indication of

Mg deficiency symptoms are not uniform green color, more obvious on older leaves - Mg as the mobile

elements are unloaded and distributed to the more need it.

6. Macro S (sulfur)
Without these elements will not produce the protein, S deficiency and stunted plants will be pale

leaf color, especially on young leaves.

7. Micro Fe (Ferrum)
MLP plays respiration process, activate oxygen to produce energy MLP. Ferro valency 2 and soluble

in water often indicates the electrical element behaviour with other, to overcome the valence

should be wrapped with chelating agent, who later was chosen EDTA (ethylene diamine tetracetate) to

form Fe-EDTA, who can either wrap fe (disabling the electrical charge ). Stability can only survive

up to pH 6.0 more than that .. begin to slack ... so that the pH of 6.5 Mangan will be able to

issue blanket fe from chelating agent,will react Ferry phosphate-phosphate formed sedimentary and

can not be absorbed (pass chlorosis)

8. Micro Mn (manganese), Cu (copper), Zn (zinc), B (borium) and Mo (molybdate)
Essential elements who must also be available, although a small amount of preformance ... and its

concentration should not be increased arbitrarily to prevent antagonisme with another element.This

elements helps expedite the process of physiological growth.
