Important Nutrients

Nitrogen (N) = material

Nitrogen is the most well-known power supply element. Plants mostly take nitrates for their nitrogen supply. Nitrogen is necessary for:

The growth of all the green parts and formation of vegetable proteins.
The formation of chlorophyll for more energy production.
Delaying aging of plants. Plant will continue to produce more leaves and will flower at a later stage and / or ripening.
A nitrogen deficiency is indicated by:

The yellow color of old (er) sheets.
The residue of old (er) sheets.
Phosphorus (P) = building material

The phosphorus element is found in the soil in phosphate and is also absorbed by the plants in this form. Phosphates can bind to soil particles, especially when they contain a lot of calcium, iron and aluminum. The phosphor material:

Stimulates root formation.

• Makes for a good tillering of the plant.
• Is an important part of the genetic material (DNA).
• Ensures the budding and good hardening of the plant.
• A phosphorus deficiency can be recognized by:

• Dwarfism
• Darkening
• Dying leaves (spots in the magazine)
• Potassium (K)

Potassium is, in contrast to nitrogen and phosphate, no building material, but does not affect the firmness of the plant. Potassium is especially as ion (K +) in the cell fluid and keeps the cell voltage in position. Potassium is located in the soil in the form of potassium salts and dissolves relatively quickly in the soil moisture.

Potassium is required for:

• The improvement of moisture uptake by the root reduces the moisture release through the sheet. As a result, the plant is less prone to dryness and, for example, weather influences such as frost.
• The plant will get more and better quality fruits and / or flowers. Especially in fruit-bearing crops taste, smell, color and shelf life positively influenced.
• The improvement of the transports in the plant, causing important substances can be transported quickly to other parts of the plant.
• Increasing the resistance to diseases and pests, making plants less susceptible to infestation by fungi and bacteria.
• A potassium deficiency can be recognized by:

Die-off starting at the edges of the sheet.
Calcium (Ca)

The element calcium plays an important role in an active soil life. In the soil calcium is essential for the neutralization of the acidity, so that the soil is not too acidic. In general, the soil contains plenty of calcium for plant growth. A calcium deficiency in the soil has an indirect effect on the growth of plants because of the emergence of a (too) acidic soil. Many important nutrients for the plant can not be recorded in such a situation by the plant roots.
 
A calcium deficiency can be recognized by:
first yellow dots, after which the sheet dies, starting at the tip of the blade.
 
The operation of Calcium is:

•  Neutralizing value for the degree of acidity.
•  Building block in the cell walls.
• Sulfur (S)

A sulfur deficiency can be identified by cup-shaped leaves that turn purple.

Sulfur is necessary for:

• The production of vegetable proteins and amino acids.
• A favorable influence on the water balance in the form of sulphate.
• Magnesium (Mg)

A lack of magnesium gives yellowing between the veins of the leaves.

Magnesium is required for:

• The production of chlorophyll for photosynthesis (energy).
• Activation of processes in the metabolism, that have a beneficial effect on the growth quality of plants.
