Characteristics and nutritional targets

A liquid formulation produced from urea and sulphuric acid reaction, it is suitable for direct soil or in fertigation system applications. It provides slow release nitrogen and sulphur, improving vegetative build up and blossoming. It increases fruit size.
Urea Solfato has a strong acidifying effect that assists in freeing the nutritive elements already present in the soil but otherwise blocked in chemical form, making them available to the plant. It therefore increases the cation exchange capacity and chemical fertility of the treated soils.

Methods of application and dosages

Fruit trees: by fertigation at reawakening, at blossoming and during fruit growth, 4-5 applications with a dosage of 25-30 l/ha.
Horticultural crops: by fertigation during the whole crop cycle. Repeat applications frequently with a dosage of 25-30 l/ha.
Flower and ornamental crops: by fertigation system during the whole cycle. Repeat applications frequently with a dosage of 2-2.5 l per 1,000 m2.


The product can be mixed with other formulates. It is always advisable to make a small mixing essay to test compatibility.
