The fertilizer (33-0-0 + 32 SO₃), also known as ammonium urosulfate, is a mixed nitrogen fertilizer that combines nitrogen (N) in stable ammonium and urea forms, providing both immediate and long-term nutrition. In addition, it contains 32% sulfur (SO₃), which is available to plants in the form of sulfate ion. Sulfur works synergistically with nitrogen, enhancing nutrient efficiency and overall crop productivity, while improving soil fertility.
Features and benefits
Composition
Sulfur improves nitrogen absorption and contributes to the synthesis of proteins, enzymes and sulfur compounds.
Quality improvement
It enhances the protein content, yield and taste of products.
Gradual release of nitrogen
Reduces losses due to evaporation and leaching, providing prolonged nutrition.
Application flexibility
Ideal for various types of crops and application methods.
33N Booster is suitable for a wide range of crops:
Cereals (wheat, barley, corn): Improves plant growth and yield.
Industrial crops (cotton, sugar beets): Increases crop productivity and quality.
Vegetables (potato, onion, cabbage): Enhances the quality, growth and preservation of fruits.
Fruit trees (olives, citrus fruits): Improves the growth and nutrition of fruits.
Grapevines: Increases production and quality of fruit.
Indicative doses (per acre) and application methods:
Cereals (wheat, barley)
20-25 kg/ha, applied as basic fertilization and superficially before flowering.
Corn
20-30 kg/hectare, in two doses: at sowing and during growth.
Cotton
20-25 kg/hectare, before flowering.
Potato
25-30 kg/hectare, during planting and before tuber formation.
Onion and cabbage
10-15 kg/ha, with one application at planting.
Olives
1-2 kg/tree, early spring.
Vines
10-15 kg/hectare, applied at the beginning of the growing season.
Notes: Exact rates depend on soil type, crop needs and climatic conditions. It is recommended to work with a qualified agronomist to ensure correct application and optimize yields.
