DUETTO

DUETTO for its particular content of organic nitrogen, potassium and phosphorus and trace elements (boron, iron etc.) is suitable for fertilization of crops with quick growth rates (leaf and fruit vegetables) and for crops that require great quantity of potassium, for which quality is the most important factor for production (vineyard, fruit plants, tobacco etc.).

DUETTO contains only organic potassium, which does not affect the plant development. Moreover, for its content of nitrogen in organic form only, DUETTO is the best fertilizer to supply nutrition to plants in soils with high salinity and alkalinity. It can also be used on soils with excess of chlorides and on chloride-sensitive crops.

Besides providing nutrition to crops, DUETTO also releases a great quantity of organic substance and humic acids, which improves the soil structure, increasing the water supply, and activates the micro-organisms of soil, reducing the soil tiredness.

DUETTO has a high fertilizing and nutrition capacity, which is 2-2.5 times that of mineral fertilizers.

DISTRIBUTION

DUETTO is suitable for basic and pre-sowing or pre-transplanting fertilization of crops as well as for autumn-winter fertilization of fruit plants.
The spreading season is very long, from winter to spring because the organic elements have no losses. We advise to spread the product until the two weeks preceding the probable bud burst time.
DUETTO is an organic fertilizer and it is preferably slightly ploughed at max depth of 15 cm, to exploit completely the physical and biological action of the organic substance.
DUETTO can also be spread on surface (vineyards, grass orchards, drill sowing) thanks to the remarkable features and processing of the organic substance, which is not carbonized and for this reason inflates and dissolves with moisture.
The continued use of DUETTO increases the level of organic substance of soil, improving its fertility and avoiding the risks connected with the continuous intake of mineral substances.
