Algae are mono or multicellular autotrophic organisms (i.e. photosynthetic organisms) living in a humid environment. They are used in fields of food and feed, in cosmetics, paper and textile industries, in medicine and in agriculture.
In L. Gobbi srl formulations, we can find two species of algae: Ascophyllum nodosum and Laminaria digitata.
The choice to use just one kind of algae or their mixture, in the different formulations, is related to the specific characteristics of each. Ascophyllum nodosum, richer in natural bio-regulator action substances, it is recommended close to flowering in order to improve fruit set and, in the meanwhile, to increase the resistance of the flower to the adverse conditions. For this reason, it is also associated with elements such as boron, often applied in these phases. Laminaria digitata, instead, is richer in carbohydrates and substances that facilitate the absorption and the translocation of nutrients. For that reason, elements having “movement” difficulties are associated to this alga. The mixture is proposed when you have both conditions above described .

Harvest, processing and yield of derived materials.
Algae extraction takes place in the cold seas of the North with the help of pickers boats equipped with special machines or manually on the seabed, during low tide.
Subjected to the constant motion of the tides, the algae live in stressful conditions. To survive in such conditions, they have developed unique internal adjustment processes that allow them not only to resist but even to have a balanced growth.
Algae usually are very rich in iodine and alginates (surfactant role) and oligosaccharides (elicitors of defense). Also very rich in growth factors (Gibberelline, Cytokinins, Betaine), which stimulate their growth that may reach peaks of 12 cm a day in Laminaria digitata.
The process involves a washing and subsequent dehydration in open air of the collected material. After this point the dry material can follow two roads. A portion of the dehydrated material is micronized until become a flour, while another part is rehydrated. On this portion, mineral salts, growth factors, some organic substances and carbohydrates, which will be concentrated by a low temperature process, will be extracted. Subsequently the two fractions will be mixed again to obtain the final product containing a higher useful substances concentration.
You need almost 20 kg of fresh seaweeds to produce one kg average of our concentrated algic matrix.


All alga based L. Gobbi products are characterized for having a high alginates content (for a better conveyance of nutrients trough and within the leaves), in vitamins and oligosaccharides (to increase the stress resistance) and microelements.

Thanks to its natural origin, algae have peculiar properties due to their components: mineral elements, carbohydrates, protein substances, bio-regulators, “anti-stress” substances, polyamines and Vitamins. Without any external integration!

Effects of brown algae on plants

Effects on nutrition:

  • Radical nutrient absorption increased and more rapid distribution of the same in the most actively growing tissues.
  • Foliar absorption of nutrients increased due to improvement of the cell membrane permeability.
  • More rapid and uniform translocation of nutrients in plant tissues.
  • More regular course of enzymatic reactions in which trace elements are involved as co-enzymes.

Effects on physiological phenomena:

  • Increasing of photosynthesis (and thus dry matter increasing).
  • Perspiration reduction.
  • Stimulation of vegetative growth and flowering.
  • Fruit set stimulation and fruits size increasing.
  • Improvement of the organoleptic fruits characteristics (average weight and size, flesh consistency, sugar, color).
  • Slowing down senescence (eg.: chlorophyll degradation).

Anti-stress effects:

  • Resistance to thermal changes increased (early frosts, high temperatures).
  • Resistance to water shortages and salinity increased.
  • Overcoming agrochemicals stress phenomena.
  • Natural defense mechanisms activated.

Algae for integrated fruit production and quality

Tips for best results:

  • intervene with specific formulated in topic phenological phases, to promote fruit set, fruit growth and improvement of organoleptic characteristics.
  • Intervene even in mixtures with agrochemicals.
  • Intervene in mixture with meso and micro elements.
  • Employ specific formulations for prevention of particular physiological disorders such as chlorosis, bitter pit or to increase the resistance of fruit to the post-harvest diseases and to the handling.
  • Intervene with anti-stress function (eg.: frosts).
