PROPERTIES OF OUR PRODUCTS

GRENA products in 2mm micro-pellet form are obtained by crumbling the pellets. After being spread over the grassy land of vineyards, orchard, or steep terrains,

THEY REQUIRE NO FURTHER TILLAGE AND THEY DO NOT NEED TO BE BURIED IN THE SOIL.

This allows for a reduction of the doses and for a more homogenous distribution.

WHY USE GRENA FERTILIZERS?

Because our production is environmentally friendly

Because our products are obtained with low environmental impact techniques

Because we use renewable resources

PRESENCE OF AMINO ACIDS

The amino acids and peptides, which are naturally present in the soil, directly improve the supply of nourishment for plants and soil organisms. The remarkable presence of left-handed amino acids and peptides in GRENA products have an immediate effect on root proliferation. With a greater increase of the root surface, this allows faster and more effective absorption of the nutrients. Amino acids stimulate the activity of soil microorganisms.

THE IMPORTANCE OF POLYAMINES

Polyamines are essential molecules for the development of plants. They are the organic molecules obtained from breaking down amino acids. Polyamines confer resistance to drought stress and water stress. They contribute to the correct development of flower structure and to the maturation of the reproductive organs and fruits. They also aid in attracting pollinating insects and at the same time they protect the plant from the attack of pathogens.
