Description
Typology: NPK liquid | Contained elements: Nitrogen, sulphur | Appearance: Liquid | Use: Fertirrigation
Composition:
• Nitrogen (N) total: 17% | Nitric: 2.6% | Ammoniacal: 10.3% | Urea: 4.1%
• Sulphur trioxide (SO₃) water-soluble: 46%
Storage: Stable under ordinary temperatures and pressures. Store at 4°C–25°C. In case of spillage collect with sawdust and/or sand.
Characteristics:
Sulphur plays very specialised roles in the plant, as it is an important constituent of biologically active compounds. S-deficiency can
cause serious metabolic imbalances, as the plant is unable to produce proteins due to the lack of sulfur amino acids. It occurs as a
chlorosis that starts from the younger leaves. Sulphur contributes to lower pH in the soil solution, so it can be conveniently used to
correct excessively alkaline soils. For this purpose it might be distributed in fertirrigation by periodic treatments, respecting the
suggested doses. Some elements (Fe, P) in an alkaline environment are difficult to assimilate by plants; a sulphur supply makes
many other elements more available. It regulates nitrogen availability (since sulphur plays a key function in nitrification and urease
activity), thus increasing the fertilisation efficiency.
Dose Rates and Conditions of Use:
Crop | Fertirrigation
• Fruit trees: 15–18 Kg/1.000 mq
• Flowering: 10–15 Kg/1.000 mq
• Vegetable crops: 15–18 Kg/1.000 mq
• Industrial crops: 15–18 Kg/1.000 mq
In a protected environment reduce the recommended dosage by 20–25%. It is recommended to carry out a localised fertilisation
taking into account soil and crop parameters.
Miscibility: Do not mix with acid reaction products.
