A UNIQUE REALITY ON THE ITALIAN AGRICULTURAL MARKET

WHY CHOOSE GRENA?

BECAUSE OF OUR PRODUCTION OF ORGANIC FERTILIZERS, ORGANO-MINERAL FERTILIZERS, AND BIOSTIMULANTS WITH AMINO ACIDS, PEPTIDES AND POLYAMINES

A unique reality thanks our processing system: THP® (Thermal Hydrolysis Process)

A unique reality thanks to our use of renewable resources: organic substance of animal origin

A unique reality thanks to the amount of amino acids present: biostimulants by nature

A unique reality thanks to the polyamines within: natural antistress

A unique reality thanks to the end results: growth, quantity, and taste

OUR FAMILY HISTORY

1956 The birth of Grena

The birth of Grena

The GRENA s.r.l. production site was launched in 1956 by the Founder, Teresio Grena Magagna, assisted by his wife Amalia, and they produced protein hydrolysates for zootechnical use.
1980 The turning point

The turning point

In the 1980s, the turning point took place: our production and marketing of organic fertilizers started from an intuition about the potential of the organic matrix that GRENA produced, and that intuition was soon refined by research in this direction.
Anni '90 Products

New products

In the 1990s, organic products were complemented by some organo-minerals and our liquid biostimulant distillate, IDROGRENA. This ensured then and continues now to make the range of GRENA products versatile even for the most demanding clientele.
1995 The launch of the Grena brand

The launch of the Grena brand

After fifteen years during which we produced fertilizers for third-party companies, in 1995 GRENA entered the market determined to assert its own brand.
2011 Products

New product lines

Since 2011, GRENA s.r.l. has further specialized its output, adding to the pellet production a new line of products in micro flakes form, something that has immediately had excellent feedback from customers. This is because it is even more versatile than pellets and therefore suitable for use in difficult soils, greenhouses and protected crops.
2022 Expansion

New Expansion

Development, business growth and improvement of services for our customers with the expansion of warehouse and production line.

GRENA IN THE WORLD

The presence of GRENA products is no longer confined to the national market but crosses borders in Europe and beyond.

Today it is possible to count French winemakers and Spanish olive growers among the users of our biostimulants, as well as the apple producers of Poland and Germany, the horticultural productions of Hungary, Slovenia and Bosnia, fruit growers from Croatia and raspberry producers from Serbia, strawberry-growers on the island of Malta and olive-growers from Greece, Morocco, and Lebanon, producers of pistachios in Iran and banana growers in the Dominican Republic and Ecuador.

Within the great convivial feast that GRENA has become, both Italian and foreign collaborators find space for growth, achievement and satisfaction, in a mutual meeting of ideas and development for the betterment of agriculture.

Our uniquely distinctive production of organic fertilizers

  • Processing system: THP®
  • Renewable sources: selected organic substance from animal origin
  • Amount of amino acids present: Nature’s biostimulants
  • Polyamines in IDROGRENA: natural antristress
  • Results: growth, quantity, and taste

These 5 items represent the solid foundations of Grena products, something to always rely on when recommeding products for different crops.
In particular, we want to emphasize that the THP® processing system stands for thermal hydrolysis; it is therefore a guarantee that no chemical element has entered our production cycle, but that it is instead pure and simple wet cooking of the organic matrix.
