Role of Macro Nutrient

Role of Macro Nutrient

Nitrogen
To increase the plant height and stimulate growth of young plants. Creating more green plants because much of the chloroplast. As a constituent of chlorophyll of leaves.

Phosphorus
Growth of root, flower and ripening fruit or seed.

Potassium
Streamlining photosynthesis.
Increase the resistance of plants
against pests and diseases.

Magnesium.
as chlorophyll-forming material.

Calcium
The formation of fine roots, harden wood / stem of the plant, stimulates the formation of grains.

Sulfur
Assist the formation of chloroplasts, make the color of leaves become more green.

Source of Nutrients in Soil

Source of Nutrients in Soil

Nitrogen (N):
N source: the decomposition of organic materials from plants / animals.
N absorbed by plants in the form of ions NH₄⁺ or NO₃^-

Phosphorus (P):
P source : decomposition of organic materials and minerals apatite and calcium-phosphate (Ca₃(PO₄)₂).
P absorbed by plants in the form of ions HPO₄^2- or H₂PO₄^-

Potassium (K):
K source : mineral ortoklas (KAlSi₃O₈), leucit (KAl(SiO₃)₂), muscovite (KH₂Al₃(SiO₄)₃) and biotite (HK)₂(MgFe)₂(AlFe)₂Si₄O₁₂.
K is absorbed by plants in
form of K⁺ ions.

Calcium (Ca):
Ca source : mineral augite, hiperstin, hornblende and calcite (CaCO₃).
Calcium is absorbed by plants in
form of Ca²⁺ ions.

Magnesium (Mg):
Mg source : amphibole minerals (Ca(MgFe)₂Si₄O₁₂), biotite, chlorit and dolomite (CaCO₃MgCO₃).
Magnesium is absorbed by plants in
Mg²⁺ ions form

Sulfur (S):
S source : mineral gypsum (CaSO₄), barite (BaSO₄) and pyrite (FeS₂).
Sulfur absorbed by plants in
SO₄^2- ions form

Chlorine (Cl):
Cl source : mineral halite (NaCl) and sylvite (KCl). Chlor absorbed by plants in the form of Cl^- ions

Iron (Fe):
Fe source : mineral hematite (Fe₂O₃), magnetite and limonite. Fe absorbed by plants in the form of Fe²⁺ ions

Manganese (Mn):
Mn source : mineral pirolusit (MnO₂) and manganit (MnO(OH)) and braunit (MnSiO₂). Mn absorbed by plants in the form of Mn²⁺ ions

Copper (Cu) and Zinc (Zn):
Source of Cu and Zn : minerals secondary. Cu is absorbed by plants in the form of Cu²⁺and Zn in the form of Zn²⁺

Boron (B):
B source : termalin and borate minerals.
B Absorbed by plants in the form of BO₃^2-, HBO₃^2-, H₂BO₃^- and B₄O₇^2-

Molibdenium (Mo):
Mo source : granite rocks. Mo absorbed by plants in the form of molybdate ions (MoO₄^2-).

Fertilizer

Fertilizer is material to adjust the physical, chemical or biological properties of soil in order to be better for the plants.
Fertilizers containing nutrients as the raw material for plant growth.
Fertilizer is given to meet the nutrient needs of the crop.
Fertilizers can be organic or inorganic (mineral).
In addition there is also a plant supplement that function as hormones in plants to help smooth the process of metabolism, supplements are usually given for a specific purpose, for example to restore the condition of the plant after disease, supplements are usually added on commercial fertilizers.

Dieffenbachia

Dieffenbachia can be recognized by the characteristic green color of leaves varied with white or
yellow patches.
Dieffenbachia leaf tends to be darker when placed in the room, but becomes bright color when planted outdoors in sunlight.
Some literature states that dieffenbachia contains little toxic substance.

Adiantum

Adiantum can be grown inside or outside the room but can not stand direct sunlight. Adiantum can be grown on a medium rich in organic matter.
Fertilizers containing nitrogen suitable for Adiantum. The formation of spores need fertilizer with phosphorus and potassium. Adiantum grow on medium slightly moist and not too wet.

Bromelia

Bromelia are still a family of pineapple. There are many species of bromelia with a variety of colors and sizes. in nature bromelia grow on large trees, soil and rock.
Bromelia do not need much water and the roots should not be submerged in water. Bromelia do not like direct sunlight. Bromelia are relatively resistant to diseases / pests.

Sansevieria

Sansevieria trifasciata / mother-in-law's tongue, some literature states that this plant absorb harmful gases cause pollution, so Sansevieria widely planted in the room to fix the air condition in the room.
Sansevieria plants can live with a lot or a little sunshine (in the room). when stored indoors, drying plants once a week in order to keep the plants fresh.
Sansevieria does not require a lot of water, watering should only be done once a week.

ROSE

Rose is a plant with very pretty flower with thorny stems, a rose is a common shrub thrives on the cool temperate regions. rose plants require sunlight for 5 to 7 hours a day and watering in the afternoon. Roses need to be fertilized with a balanced level so that the plants grow lush with beautiful flowers, avoid grass and other plants in a pot of roses to prevent seizure of nutrients,

ORCHID

Orchids largely come from the tropics, in the nature of tropical forests orchids that grow in the ground, on big tree trunks, rocks and in the rest of the dried leaves and decayed wood that has been decomposed into humus.
Orchids generally require little sunlight and little water. Orchids have many kinds of beautiful flowers and colorful, orchid flowers can last a long time even orchids can be grown in the room with the help of the light beam.
Orchids are very easy to maintain even be grown indoors, keep in mind that orchids need less water and little sunlight regularly, and appropriate planting medium.
