Organic liquid fertilizers

The roots of the best crops

Humic acids are natural organic substances (polymers) that derive from the biological processes of decomposition of plant and animal waste. They are presented as complex macromolecules formed mainly by amino acids, carbohydrates and inorganic elements.


DUETTO LIQUID and DUETTO LIQUID PLUS constitute the result of a careful selection of organic substances of plant origin. It contains plant extracts produced by microbial fermentation as well as humic and fulvic acids.
Given the organic nitrogen and potassium content of the product, as well as the high quality organic matter, it is suitable for fertilizing either fast-growing crops (horticultural crops of leaves and fruits) as those of slower growth and demanding of potassium, in those that quality and production constitute the most important factor (vineyard, olive, fruit trees, tobacco, etc …).


DUETTO LIQUID and DUETTO LIQUID PLUS contain only organic nature potassium that positively influences the development of the plant. In addition, because of its nitrogen content also of an organic nature, they are able to nourish the plants in areas with high salinity and alkalinity. Its use is also advised in areas where there are excess chlorides or to fertilize crops especially sensitive to chlorine.

DUETTO LIQUID and DUETTO LIQUID PLUS, in addition to nourishing the crops, provide a large amount of organic matter and humic acids that improve the structure of the land, increase water reserves and activate soil microorganisms, reducing soil fatigue and improving soil fertility.
