Product Description

Product:  Nitrogen-Rich Sulfate Fertilizer crystals

Molecular formula: (NH₄)₂SO₄ 

Description: Ammonium sulfate is widely used as a nitrogen fertilizer in agriculture. Its high nitrogen content (21% nitrogen) provides essential nutrients for plant growth. It is particularly suitable for crops that require high nitrogen levels, such as leafy greens, grains, and grasses. Ammonium sulfate helps improve crop yields, promotes healthy plant growth, and enhances nitrogen utilization efficiency.
1. Nitrogen Source: Ammonium sulfate is an excellent source of nitrogen for plants. It provides both ammonium (NH4+) and sulfate (SO4²-) ions. The ammonium form of nitrogen is readily absorbed by plant roots, supporting their growth and protein synthesis. The sulfate form contributes to sulfur nutrition, an essential nutrient for plant development.
2. Water Solubility: Ammonium sulfate is highly soluble in water, allowing for easy application and rapid nutrient availability to plants. Its solubility ensures efficient nutrient uptake by plant roots and minimizes nutrient losses through leaching.
3. pH Adjustment: Ammonium sulfate has an acidic reaction when dissolved in water. This property makes it useful for pH adjustment in various applications. In agriculture, it can help lower the pH of alkaline soils, making them more suitable for certain crops.

FAQ

Q1: What does this product do to the crop?
A: It's suitable for general soil and crops, can make branches and leaves grow vigorously, improve fruit quality and yield, enhance crop resistance to disasters.

Q2: What kind of fertilizer is this suitable for use as a crop fertilizer?
A: Ammonium sulfate can be used as base fertilizer, topdressing fertilizer and seed fertilizer.

Q3: What should I pay attention to when using this product?
A: Do not contact or mix with other alkaline fertilizers or alkaline substances to avoid reducing fertilizer efficiency.
Not suitable for application on acid soil.
It is not suitable to apply ammonium sulfate on the same cultivated land for a long time, otherwise the soil will become sour and cause compaction. If it is necessary to apply, can be appropriate with some lime or organic fertilizer. However, it must be noted that ammonium sulfate cannot be mixed with lime to prevent the decomposition of nitrogen loss. Generally, the combined application of the two should be separated by 3~5 days.
