The nitrogen is entirely in ammonium form (NH₄⁺), allowing for rapid plant uptake and immediate growth stimulation. The high sulfur content is essential for the formation of proteins and chlorophyll, and contributes to efficient nitrogen utilization.\u003c\/p\u003e\n\u003cp\u003eWith its natural acidifying effect, ammonium sulfate lowers the pH of calcareous soils. This enhances the availability of trace elements such as iron, manganese, and zinc, helping to prevent deficiencies and improve the plant’s nutrient uptake capacity. This makes it especially suitable for soils with a high pH or following fertilization with phosphate- and potassium-rich compost.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eFor Demanding Crops and Maximum Nutrient Efficiency\u003c\/h2\u003e\n\u003cp\u003eThis fertilizer is particularly well-suited for sulfur-demanding crops such as potatoes, cabbages, onions, leeks, asparagus, lettuce, and strawberries.

Preferably work it lightly into the top layer of soil or allow the granules to be washed in by expected rainfall. In dry conditions, watering after application is recommended to speed up nutrient uptake. Application is ideally done at the start of the growing season or as targeted supplementary fertilization during cultivation. Avoid applying together with lime-based fertilizers in a single pass to prevent nitrogen loss through ammonia volatilization.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eRecommended Dosage of Ammonium Sulfate\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eLawns and ornamental gardens: 50–80 g\/m²\u003c\/li\u003e\n\u003cli\u003eVegetable gardens and crops: 50–100 g\/m², depending on the crop and nitrogen requirements\u003c\/li\u003e\n\u003cli\u003eCabbages, leeks, rhubarb: up to 90 g\/m²\u003c\/li\u003e\n\u003cli\u003ePotatoes: approx. 70 g\/m²\u003c\/li\u003e\n\u003cli\u003eFruit crops and strawberries: 50–80 g\/m²\u003c\/li\u003e\n\u003cli\u003eFruit trees, berries, and grapes: 40–60 g\/m²\u003c\/li\u003e\n\u003cli\u003ePotted and container plants: 5–10 g per litre of potting soil, mix well\u003c\/li\u003e\n\u003cli\u003eCompost improvement: approx. 50 g\/m² per 20–30 cm layer\u003c\/li\u003e\n\u003cli\u003eProfessional use (agriculture): approx. 475 kg\/ha for 100 kg nitrogen requirement per hectare\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eApplication Period\u003c\/h2\u003e\n\u003cp\u003eAmmonium Sulfate Fertilizer can be applied throughout the entire growing period of the crop.
