Ammonium sulphate 21% nitrogen(N) 25 kg
Ammonium sulphate 21% is a mineral fertiliser containing 21% nitrogen (N) in ammonia form and sulphur (SO3) in soluble form. This combination makes the product particularly suitable for crops that require a prolonged supply of nitrogen over time, while sulfur improves the absorption of other nutrients, particularly in alkaline soils.
What is ammonium sulfate used for?
Ammonium sulphate is a nitrogen fertiliser with multiple functions:
- Nitrogen supply: Nitrogen in ammonia form is slowly released into the soil, ensuring constant nutrition. This characteristic promotes vegetative development, improving leaf formation and photosynthesis.
- Soil acidification: Thanks to sulfur, ammonium sulphate lowers the pH of the soil, improving the availability of microelements such as iron and phosphorus, which in alkaline soils tend to become less accessible to plants.
- Improved crop quality: The combined action of nitrogen and sulfur promotes the formation of proteins and amino acids, helping to increase the quality of the final product, such as the protein content of cereals or the robustness of fruits.
The advantages of using Ammonium Sulphate 21%:
- Constant nitrogen nutrition: Sustained release of nitrogen into the soil, reducing the risk of leaching.
- pH improvement: Reduction of soil alkalinity to improve the availability of nutrients such as phosphorus and iron.
- Vigorous growth: Promotes vegetative development and increases crop yields.
