DUETTO 3-3-7


DUETTO 3-3-7, due to its high content of organic nitrogen, phosphorous and potassium, as well as microelements (boron, iron etc) is suitable for fertilising both rapid growing crops (horticultural leaf or fruit crops) and slower growing or potassium demanding crops in which quality and production are the most important factors (plants, vines, olives, fruit trees etc).

DUETTO 3-3-7 only contains natural organic potassium which positively influences the plant’s development. In addition, due to its content of exclusively organic natural nitrogen, DUETTO is able to nourish plants in areas with high levels of saline and alkaline. Its use is also recommended in areas where there is excess chlorine or for crops particularly sensitive to chlorine.


In addition to nourishing crops, DUETTO 3-3-7 provides a large amount of organic matter and humic acids which improve the ground’s structure, increase hydric reserves and activate the soil’s micro-organisms, attenuating the ground’s fatigue, that is to say activating and improving soil fertility. As a result, DUETTO 3-3-7 has significant fertilising and nutritional benefits for the crops.
