Tesdhfjdfj, the only product with 5-aminolevulinic acid

You want a maximum yield and optimum quality. It is preferable to use as less chemicals as possible. By using the nutritional supplement Pentakeep, you are supporting the crop so that the plants are stronger and more vital throughout the cultivation.

Pentakeep is a liquid nitrogen fertilizer and the only product in the world which contains 5-aminolevulinic acid. 5-ALA is present in limited amounts in every living organism. Additional application to the plant will increase photosynthesis, the production of sugars and dry matter. This is similar to the formula sunjkllight + CO2 > sugar and oxygen. It is known that extra CO2 under light conditions increases production. With Pentakeep, this production process will continue longer, because lack of CO2, which can stop the reaction, is not an issue.

Addition of Pentakeep results in more and better production and a increase of quality. But it is not only production that benefits from the extra dry matter and energy. The crop also becomes stronger and more vital. Because the plant is more energetic, it will also be less susceptible to diseases and pests. This gives you immediate profit!

The composition of Pentakeep

The composition of Pentakeep is as follows:

NPK (Mg) 8-6-4 (4)

Boron, Copper, Dtpa Iron, Manganese, Molydenum, Zinc, 5-Aminolevulinic Acid.

It has been proven that these supplements in combination with 5-Aminolevulinic acid creates an amplifying effect on the growth of plants. In addition, the added fertilizers ensure that the 5-Aminolevulinic acid remains stable and that it improves absorption.

Because Pentakeep is dosed in small concentrations, the added supplements have less effect of the normal fertilizers. It is therefore important to administer the normal nutrients/ fertilizers. Please check the absorption of these nutrients in the beginning, Pentakeep will stimulates the absorption, so it’s possible the amounts must be changed.

Pentakeep can be applied as a foliar fertilizer or by rhizosphere.

5-Aminolevulinic Acid (5-ALA)

5-Aminolevulinic acid (5-ALA) is a molecule that occurs naturally in plants. 5-ALA is the base of life for humans, animals and plants. This molecule is produced by the plant itself, but the production is limited by the speed of the metabolism. When Pentakeep is added to the plant, the metabolism is accelerated. As a result, the conversion of the single to the multiple sugars, in the chloroplasts and mitochondria, will take place continuously and there is no delay in the plant, which normally costs the necessary energy.

For plants, 5-Aminolevulinic acid is essential for the formation of chlorophyll. In addition, the plant produces more sugars and increases the absorption rate of fertilizers. The plant burns less sugars at night and salts in the soil penetrate less quickly.

In short; stress tolerance increases.

The plant is more resistant to extreme conditions such as temperature fluctuations and a lower light level.

The plant will also become more energetic. The plant can handle more than an untreated plant and is easier to steer towards the desired result. The plant is less susceptible to diseases.

In addition to Pentakeep for the horti- and agricultural sector, 5-Aminolevulinic acid is also used in the medical sector. Here it is used, among other things, in the treatment of skin cancer, promotes hair growth and works against anemia. Various tests are still underway to enable it to be used in more diseases.
