Ammonium Sulfate 1 kg

Ammonium sulfate 1 kg

Ammonium sulfate (NH₄)₂SO₄ is a classic nitrogen-sulfur fertilizer that works on all soil types. It contains 21% nitrogen in the ammonium form and 24% sulfur. It is particularly effective on alkaline soils, where it acidifies the environment and improves nutrient uptake. An ideal choice for sulfur-loving crops: cabbage, onions, garlic, and legumes.

Specifications

Advantages

• Dual action: supplies plants with nitrogen and sulfur simultaneously
• The ammonium form of nitrogen does not leach from the soil and lasts longer
• Acidifies alkaline soils, improving the uptake of phosphorus and micronutrients
• Sulfur improves protein quality, taste, and aroma of fruits
• Dissolves well in water — suitable for root and foliar feeding
• Works even at low temperatures
• Cost-effective compared to other nitrogen fertilizers

What nitrogen and sulfur provide to plants:

• Nitrogen: a building block for proteins, chlorophyll, and enzymes. Stimulates the growth of leaves and shoots, increases yield.
• Sulfur: essential for the synthesis of amino acids, vitamins, and essential oils. Improves the taste, aroma, and shelf life of fruits.
• In summary: nitrogen without sulfur is absorbed less efficiently, so ammonium sulfate is the optimal combination for balanced nutrition.

Application guidelines:

Important recommendations:

• Don’t overdo it: excess nitrogen leads to plant legging, delayed flowering, and reduced disease resistance
• Spread evenly: when applying in dry form, the fertilizer should be spread evenly and worked into the soil to a depth of 5–10 cm
• Water after application: to dissolve the granules and ensure rapid uptake
• Do not use in late fall: nitrogen stimulates growth, which can reduce the winter hardiness of perennial crops
• Compatibility: mixes well with phosphorus and potassium fertilizers

For which crops is ammonium sulfate the best choice:

• Cabbage family: all types of cabbage, radish, radish, mustard — they thrive on sulfur to develop their characteristic flavor
• Alliaceae: onions, garlic, leeks — sulfur enhances phytoncidal properties and pungency
• Legumes: peas, beans, soybeans — improves nitrogen fixation from the air
• Cruciferous: rapeseed, mustard — sulfur is a component of glucosinolates
• Crops on alkaline soils: the acidifying effect improves the uptake of phosphorus and micronutrients

💡 Tip: It is better to apply ammonium sulfate in the spring rather than in the fall. Unlike nitrate, it doesn’t act as quickly, but it nourishes plants for a longer period. It’s ideal for soils with a pH above 7, where it acidifies the environment and makes nutrients more available.
