1、Crystalline Ammonium Sulfate

Crystalline Ammonium Sulfate is a high-quality nitrogen-sulfur fertilizer produced as white or transparent crystals. In addition to supplying essential nitrogen, it is a rich source of sulfur, significantly improving both quality and yield of crops.

2、White Crystalline Fertilizer with High Nitrogen Content, Agricultural

UreaProduct Type: High-purity nitrogen fertilizer (46% N content), a primary source of nitrogen for plant growth. Applications: Base fertilizer and topdressing for staple crops (wheat, rice, corn, etc. ), as well as industrial applications (e. g., feed additives).

3、Ammonium Sulfate

Ammonium sulfate is defined as a water-soluble granular fertilizer used to supply nitrogen while promoting some acidification of soil, containing approximately 24% sulfur.

Ammonium sulfate: a key component of fertilizer and soil care

Ammonium sulfate is an inorganic chemical compound that acts as an artificial fertilizer. It is formed by the reaction of ammonia with sulfuric acid, resulting in the formation of white crystalline granules. It is a crystalline substance, well soluble in water.

Ammonium Sulfate Fertilizer: High

Ammonium Sulfate (21-0-0-24S) delivers readily available nitrogen and essential sulfur in a stable, soluble form. This dual-nutrient fertilizer is specifically engineered to address both nitrogen requirements and sulfur deficiencies in modern cropping systems.

Ammonium Sulfate Fertilizer – High

As a reliable nitrogen and sulfur fertilizer, ammonium sulfate is ideal for promoting plant health and improving soil quality. It helps to optimize growth in a wide range of crops such as corn, wheat, and vegetables.

Ammonium Sulfate

Ammonium sulfate has an acidifying effect on soil due to the nitrification process, not from the presence of sulfate, which has a negligible effect on pH. The acid-producing potential of ammonium sulfate is greater than the same N application from ammonium nitrate, for example.

Ammonium Sulfate Crystal – Fast

Terafon® Ammonium Sulfate Crystal is a premium, highly water-soluble fertilizer supplying both nitrogen (≈21%) and sulfur (≈24%) for optimal crop growth. Its fine crystalline form ensures fast nutrient release, supporting rapid uptake through roots or foliar application.

What Is Ammonium Sulfate Used For? Fertilizer Uses, Soil Benefits, and

As a chemical fertilizer, ammonium sulfate contains essential nitrogen in the ammonium form and plant-available sulfur as sulfate. Farmers choose ammonium sulfate fertilizer because it delivers nitrogen and sulfur together. That two-in-one package fits crops that need both nutrients at the same time for steady crop growth.

Regarding the question of whether high-sulfur nitrogen fertilizer is crystalline ammonium sulfate, we need to analyze the issue in detail from three aspects: chemical composition, physical properties, and practical applications.

I. Chemical Composition

1. Crystalline Ammonium Sulfate: Crystalline ammonium sulfate is a common fertilizer with the chemical formula ((NH_4)_2SO_4). It consists of two primary elements: nitrogen (N) and sulfur (S). In terms of molecular structure, it forms a highly symmetrical ionic crystal lattice, characterized by distinct ionic bonds.

2. High-Sulfur Nitrogen Fertilizer: The chemical composition of high-sulfur nitrogen fertilizer is more complex, typically containing multiple nutrients and trace elements. Its specific components vary depending on the type and production process. For example, urea is a common form of high-sulfur nitrogen fertilizer, with the chemical formula (CO(NH_2)_2). Besides nitrogen, it also contains carbon (C), oxygen (O), and hydrogen (H).

II. Physical Properties

1. Crystalline Ammonium Sulfate: Crystalline ammonium sulfate exhibits clear crystalline characteristics, which can be directly observed under normal temperatures. Its appearance is usually white or pale yellow powder, with moderate hygroscopicity. When heated or dissolved, it transitions into a colorless, transparent liquid.

2. High-Sulfur Nitrogen Fertilizer: The physical properties of high-sulfur nitrogen fertilizer vary by type. For instance, urea appears as white crystals with strong hygroscopicity and deliquescent properties, while diammonium phosphate (DAP) presents as white granules with good thermal stability and water solubility.

III. Chemical Properties

1. Crystalline Ammonium Sulfate: When reacting with acids, crystalline ammonium sulfate releases ammonia gas ((NH_3)) and forms corresponding sulfates. Additionally, it exhibits high thermal stability, remaining stable even at elevated temperatures.

2. High-Sulfur Nitrogen Fertilizer: The chemical properties of high-sulfur nitrogen fertilizer are diverse. For example, urea reacts with acids to release carbon dioxide ((CO_2)) and form carbonates, while diammonium phosphate decomposes into phosphoric acid and ammonia gas under high temperatures.

IV. Application Effects

1. Crystalline Ammonium Sulfate: As a traditional nitrogen fertilizer, crystalline ammonium sulfate is widely used in agriculture to effectively provide plants with essential nitrogen. its high cost and sensitivity to environmental factors limit its usage scope and quantity.

2. High-Sulfur Nitrogen Fertilizer: Due to its complex composition and varied physical properties, high-sulfur nitrogen fertilizer has broader applications in agriculture. It can meet the needs of different crops, improving yield and quality. its complexity and higher cost require careful selection based on specific conditions.

High-sulfur nitrogen fertilizer is not the same as crystalline ammonium sulfate. Although both contain nitrogen, they differ significantly in chemical composition, physical properties, chemical behavior, and application effects. the choice and use of high-sulfur nitrogen fertilizer should be guided by scientific principles and practical requirements.
