to base of seaweed Ascophyllum nodosum


General Details

algaren is a nutritional catalyst with phytostimulant activity to base of seaweed Ascophyllum nodosum obtained through a productive process which mainteins unchanged the natural components.

algaren brings all the substances present in the seaweed (aminoacids, vitamins, phytohormones, alginates, Betaine, etc) that are essential for the plants.

The periodic use of algaren allows a balanced vegetative and productive crops development by facilitating the recovery when parasites or adverse causes (freeze, drought, herbicidal treatments, crisis of transplant, etc) interfere with the normal functioning of them.

Its use is especially recommended in the periods of greatest vegetative activity of the plants.


Extracts of Ascophyllum nodosum seaweeds: 30.0%
Total Nitrogen (N): 1,5 %
Potassium oxide (K2O) sol. in water: 5,0 %
Total organic Carbon (C): 10,0 %

Formulation: Liquid


The application of algaren in the vegetative phases allows:

• an increase of the resistance to environmental stress;
• an increase of leaf surface and chloropyllian photosintesys;
• an increase of root development in starting phases with a consequent greater capacity of absorption of nutrients;
• a reduction of the susceptibility to meso and micro-deficiencies;
• a better storage after the harvest and a greater resistance to the transport.

Doses and modality of use

Foliar use:  The dosage is referred to about 1.000 L of water for ha.

Grapes (wine and table), Apple, Pear, Peach, Cherry, Kiwi, Citrus, Olive, Plum, etc:
