AM 21 is an ammonium sulfate fertilizer containing 21% ammoniacal nitrogen (NH₄) and 24% sulfur (SO₃). It is used for basal application and top dressing of various agricultural crops, including winter and spring wheat, barley, rapeseed, corn, sunflower, soybeans, peas, sugar beet, potatoes, vegetables, and fruit trees. The fertilizer is characterized by precise dust-free application, plant-available sulfur, rapid solubility, and composition stability, ensuring effective plant nutrition and contributing to increased yield.
Rapeseed, as an agricultural crop, requires a comprehensive approach to fertilization, including seed preparation, basal fertilization, pre-sowing fertilizer, and top dressing during the vegetative period. To ensure high rapeseed yield, it is necessary to correctly dose nitrogen, phosphorus, potassium, sulfur, and trace elements, taking into account soil type and fertility. Basal fertilization may include ammonium nitrate, urea, UAN, superphosphate, and other complex mixtures, while top dressing is carried out using ammonium nitrate, urea, and other nitrogen fertilizers.
When growing rapeseed, it is important to adhere to sowing deadlines, provide sufficient moisture, and regularly monitor plant health to prevent diseases. Rapeseed is resistant to some diseases but requires careful agronomic care. The use of AM 21 fertilizer contributes to optimal plant nutrition with sulfur and nitrogen, which is especially important for forming a high-quality rapeseed yield under various climatic conditions.
