Ammonium Chloride: High Ammoniacal Nitrogen Content in Fertilizer Components

1、Ammonium Fertilizers

Ammonium fertilizers are defined as inorganic fertilizers produced by the fixation of atmospheric nitrogen (N2), characterized by a typical δ15N value range between −6‰ and +6‰. You might find these chapters and articles relevant to this topic.

2、Ammonium Chloride in Fertilizer Blends – Benefits, Uses & Supply

With 25% nitrogen content, Ammonium Chloride serves as a powerful nitrogen donor in compound and blended fertilizers. It improves crop yields without nitrogen volatilization losses often associated with urea.

3、Dry Granulation of Ammonium Chloride for Fertilizer

Granular ammonium chloride can serve as an alternative nitrogen source in mixed fertilizers, addressing the inherent issues with ammonium chloride while improving its storage and transportation properties, thus resolving supply chain inventory shortages.

Ammonium Chloride

Ammonium chloride is an excellent source of both N and Cl- for coconut, oil palm, and kiwifruit, which are Cl responsive crops. Ammonium chloride is as acid forming as (NH4)2SO4 per unit of N, and this effect is undesirable in acidic soil, especially if liming costs are excessive.

Application of ammonium chloride in agriculture: rational use of

Ammonium chloride usually contains between 24% and 26%, which is cheaper than urea (46% nitrogen content), and can continuously and stably release nitrogen. This makes it a favorite among many farmers, especially suitable for growing fast-growing vegetables with short growth cycles.

Ammonium Chloride Fertilizer

Ammonium chloride serves as an effective source of both nitrogen (N) and chloride (Cl) for these Cl-responsive crops. This dual benefit ensures optimal nutrient availability for their growth and development.

Ammonium Chloride

In agriculture, ammonium chloride serves as an effective nitrogen source in fertilizers, helping to enhance soil fertility and crop yields. Its ability to release nitrogen slowly makes it particularly valuable for crops that require sustained nutrition over time.

Ammonium Chloride(N)

Ammonium chloride is a fast-acting nitrogen fertilizer made by the direct reaction of synthetic ammonia and hydrochloric acid. It contains 24-25% nitrogen and dissociates into chloride ions and ammonium ions in the soil.

Maximizing liquid fertilizer concentration during ammoniacal nitrogen

Abstract Hollow fiber membrane contactors (HFMC) can recover high-purity ammonium (liquid) fertilizer from wastewater with low energy and area footprint. Previous studies examined factors such as pH, initial ammonia concentration, flow rate, stream configuration, and acid-stripping solution.

SPIC Ammonia (Agricultural Grade)

When ammonium Chloride is applied as basal or top dressing for cultivated crops, loss of nitrogen is very less. Consequently more N will be utilized by the crop, thereby fertilizer use efficiency is increased. Ammonium Chloride fertilizer application is recommended for saline and alkaline soils

Ammonium chloride (NH₄Cl) is a commonly used nitrogen fertilizer, primarily composed of ammonium chloride. In agricultural production, ammonium chloride plays a significant role as a nitrogen fertilizer, promoting crop growth and increasing yields. The following sections provide a detailed analysis of its nitrogen content:

1. Chemical Properties of Ammonium Chloride Ammonium chloride is a white, crystalline solid that is highly soluble in water. Its chemical formula, NH₄Cl, consists of an ammonium ion (NH₄⁺) and a chloride ion (Cl⁻). The molecular weight of ammonium chloride is 73.56, with a nitrogen mass fraction of 21% and a chlorine mass fraction of 78%.

2. Nitrogen Content in Ammonium Chloride The nitrogen content refers to the amount of nitrogen (in grams) present in one kilogram of ammonium chloride. According to the national standard GB/T 2364-2025 Determination of Nitrogen Content in Fertilizers, the nitrogen content is determined by measuring a specific sample of ammonium chloride using methods such as titration or combustion analysis.

3. Standards for Nitrogen Content Based on GB/T 2364-2025, ammonium chloride is classified into three grades:

First-grade ammonium chloride (≥46% nitrogen content),
Second-grade ammonium chloride (≥40% nitrogen content),
Third-grade ammonium chloride (≥30% nitrogen content).

First-grade ammonium chloride has the highest nitrogen content, while third-grade has the lowest.

4. Factors Affecting Nitrogen Content The nitrogen content of ammonium chloride depends on factors such as the source of raw materials, manufacturing processes, and storage conditions. Generally, first-grade ammonium chloride has higher nitrogen content compared to third-grade. Additionally, variations in product quality among manufacturers may occur, so verifying the actual nitrogen content before use is critical.

5. Applications of Ammonium Chloride As a nitrogen fertilizer, ammonium chloride provides essential nitrogen nutrition for crops. It is often mixed with phosphate and potassium fertilizers to achieve balanced nutrient supply. it can be used for soil improvement and plant disease control.

6. Safety Considerations When using ammonium chloride, safety precautions are necessary:

Avoid contact with acidic substances to prevent toxic gas release.
Store in cool, well-ventilated areas away from direct sunlight and high temperatures to prevent decomposition.
Use protective equipment such as gloves and masks to avoid skin or eye contact.

Ammonium chloride is a valuable nitrogen fertilizer with high ammoniacal nitrogen content. For optimal crop yield and soil health, it should be applied based on crop requirements and soil conditions. Proper storage and handling ensure safe and effective use in agricultural production.
