AOLANSU Agricultural Ammonium Sulfate is a high-quality nitrogen sulfur fertilizer designed for modern agricultural production. It provides two essential nutrients, nitrogen (N) and sulfur (S), helping crops achieve balanced nutrition and supporting healthy growth throughout different development stages.
Manufactured by Shandong AOLANSU Environmental Protection Technology Co., Ltd., a professional fertilizer manufacturer in China, this product is produced through advanced crystallization technology with strict quality control. The fertilizer features high purity, excellent water solubility and stable nutrient content, making it suitable for global agricultural applications.
Unlike nitrogen-only fertilizers, Agricultural Ammonium Sulfate supplies both ammonium nitrogen and sulfur in one product. This combination makes it especially suitable for sulfur-deficient soils, alkaline soils and crops with high sulfur requirements.
Nitrogen is essential for chlorophyll formation, leaf expansion and plant growth. Sulfur participates in amino acid synthesis, protein formation and enzyme activity. When sulfur availability is insufficient, crops may experience reduced growth quality and inefficient nitrogen utilization.
AOLANSU Agricultural Ammonium Sulfate provides nitrogen and sulfur simultaneously, helping farmers achieve more complete nutrient management compared with traditional nitrogen fertilizers.
Many agricultural areas suffer from alkaline soil conditions where certain nutrients become less available to crops. Agricultural Ammonium Sulfate has mildly acidic characteristics and is commonly applied in alkaline soils to improve sulfur availability and support balanced soil nutrient management.
Produced through controlled crystallization technology, AOLANSU ammonium sulfate fertilizer features uniform white crystals, low moisture content and excellent storage stability. The product maintains good flowability during transportation, storage and fertilizer application.
Agricultural Ammonium Sulfate can be used for various crops including rice, wheat, corn, vegetables, fruit trees, cotton, tea and other commercial crops. It is particularly suitable for crops with higher sulfur demand such as garlic, onion and oil crops.
Both ammonium sulfate and urea are important nitrogen fertilizers, but they provide different nutrient functions. Choosing the right fertilizer depends on soil conditions, crop requirements and nutrient management goals.
| Comparison | Agricultural Ammonium Sulfate | Urea Fertilizer |
| Main Nutrients | Nitrogen + Sulfur | Nitrogen only |
| Nitrogen Form | Ammonium nitrogen, directly available for crops | Requires conversion before plant absorption |
| Sulfur Supply | Provides sulfur for protein synthesis and crop quality | Does not contain sulfur |
| Suitable Soil | Especially suitable for alkaline and sulfur-deficient soils | Widely used in general nitrogen fertilization |
| Crop Requirements | Suitable for sulfur-demanding crops | Mainly used for nitrogen supplementation |
AOLANSU Agricultural Ammonium Sulfate is manufactured under controlled production conditions to ensure consistent quality and reliable agricultural performance.
Qualified raw materials are carefully selected and tested before entering production. Key indicators including purity, moisture content and impurity levels are controlled to maintain stable fertilizer quality.
The production process adopts mature evaporation and crystallization technology. Through controlled crystallization conditions, the product achieves uniform crystal structure, high purity and excellent solubility.
Each production batch is tested for nitrogen content, sulfur content, moisture, particle size and appearance. Quality documents including COA and MSDS can be provided according to customer requirements.
Agricultural Ammonium Sulfate can be applied before planting and incorporated into soil. This method provides nitrogen and sulfur nutrients during the early growth stage and supports stronger root development.
During key crop growth stages such as tillering, flowering or fruit development, ammonium sulfate fertilizer can be applied as top dressing to supplement crop nutrient requirements.
Due to its good water solubility, Agricultural Ammonium Sulfate can be dissolved and applied through irrigation systems, allowing precise nutrient delivery to crop root zones.
The uniform crystal structure and good flowability make the product suitable for large-scale agricultural operations using fertilizer spreading equipment.

In some wheat-growing regions where soil alkalinity limits nutrient availability, growers use Agricultural Ammonium Sulfate as part of their nitrogen management program to supplement sulfur nutrition and improve fertilizer balance.
During field application, farmers reported that the product dissolved quickly, was easy to spread and provided stable nutrient supply during crop growth. The experience showed that ammonium sulfate fertilizer can be an effective option when additional sulfur nutrition is required.
Garlic is a sulfur-demanding crop, and sufficient sulfur availability plays an important role in crop quality development. Agricultural Ammonium Sulfate is commonly included in fertilization programs for garlic production to provide both nitrogen and sulfur nutrients.
Growers typically apply the fertilizer according to soil testing results and crop growth stages to achieve balanced nutrient management.
Agricultural Ammonium Sulfate is mainly used as a nitrogen and sulfur fertilizer. It supplies ammonium nitrogen for plant growth and sulfur for protein synthesis, making it suitable for grain crops, vegetables, fruit trees and sulfur-demanding crops.
High-quality Agricultural Ammonium Sulfate normally contains approximately 21% nitrogen and 23%-24% sulfur. The exact specification depends on product grade and manufacturing requirements.
Yes. Agricultural Ammonium Sulfate is commonly used in alkaline soils because its acidic characteristics help improve sulfur availability and support better nutrient management.
Yes. It can be applied to many vegetables and fruit crops. For sulfur-sensitive or sulfur-demanding crops such as garlic, onion and some fruit crops, ammonium sulfate can provide valuable sulfur supplementation.
The main difference is nutrient composition. Ammonium sulfate provides both nitrogen and sulfur, while urea mainly provides nitrogen. Farmers choose between them according to soil conditions and crop nutrient requirements.
Yes. AOLANSU provides customized packaging, labeling and fertilizer supply solutions according to customer market requirements, including distributor and bulk agricultural purchasing needs.
Shandong AOLANSU Environmental Protection Technology Co., Ltd. is a professional fertilizer manufacturer in China specializing in agricultural fertilizer production and international supply.
