1、Recent advances in the chemistry of nitrogen

Nanofertilizers are a promising technology for sustainable agricultural production and are discussed in detail in this review. Fertilizer discovery is an important breakthrough that has rapidly increased crop yield globally (Vojvodic et al., 2014).

2、Ammonium bicarbonate used as a nitrogen fertilizer in China

The present article gives a brief description of a modified process forproducing ammonium bicarbonate, and also reports on he fforts madeby agricultural chemists to make more effective use of this fertilizer.

3、Recovering, Stabilizing, and Reusing Nitrogen and Carbon from

Ammonium carbonates are a group of fertilizer materials that include ammonium bicarbonate, ammonium carbonate hydrate, and ammonium carbamate. They can be synthesized from diverse nutrient-bearing liquid waste streams but are unstable in a moist environment.

4、The combination of different nitrogen fertilizer types could promote

These results suggest that compared with conventional fertilization method (S0), the 20% treatment is a more effective fertilization method that prevents inhibition of straw decomposition, promoting rice growth and yield, and improving nitrogen (N) use efficiency.

CHAPTER 3. THE FERTILIZER SECTOR

Straight fertilizers with a low content of nitrogen are gradually losing their importance - the importance of ammonium sulphate has declined during the last few years. The main form of liquid nitrogen is anhydrous ammonia. The main straight phosphate fertilizer is superphosphate.

What kind of fertilizer is ammonium bicarbonate? How should it be used

As far as the nutritional function of fertilizer is concerned, ammonium bicarbonate is a fertilizer that is directly absorbed. It does not contain intermediate products and final decomposition products, and long-term application will not affect soil quality.

Precautions for mixing fertilizers and fertilizers

Ammonium bicarbonate emits a certain concentration of ammonia gas, which is toxic to the active bacteria in the fertilizer. Phosphate fertilizers cannot be mixed with zinc. Phosphorus and zinc produce a chemical reaction to form zinc phosphate, reducing the utilization of phosphorus and zinc.

Ammonium Fertilizers

Ammonium fertilizers refer to a type of fertilizer that contains ammonium ions, which can include various forms such as ammonium nitrate and ammonium phosphates.

Phosphorus Fertilizers

Phosphorus is applied as ammonium phosphates or superphosphate, and phosphorus fertilizers are often characterized by their (N–P–K, nitrogen–phosphorus–potassium) composition.

Environmentally friendly agronomically superior alternatives to

The above calculations are indicative of the potentially low-cost and yet agronomically effective phosphate fertilizers that can be replacements for chemically processed phosphate fertilizers.

Phosphate fertilizers and ammonium bicarbonate are both commonly used in agriculture, each with distinct characteristics and optimal应用场景. Determining which fertilizer is more effective depends on factors such as soil conditions, crop requirements, and application methods. Below is a detailed comparison of their properties and suitability.

1. Phosphate Fertilizers

Definition and Composition

Phosphate fertilizers contain phosphorus (P), an essential nutrient for plant growth. Phosphorus plays a critical role in photosynthesis, protein synthesis, cell division, and root development.

Functions and Benefits

• Promotes Plant Growth: Enhances root and stem development, improving crop yields.
• Boosts Disease Resistance: Appropriate phosphorus levels strengthen plants’ ability to resist pests and diseases.
• Improves Soil Structure: Increases soil water-retaining capacity and nutrient retention.

Application Methods

Phosphate fertilizers are applied in solid granular or liquid form. The type and dosage depend on crop needs and soil conditions. For example:

• Crops requiring high phosphorus (e.g., rice, sugarcane) benefit from high-phosphorus formulations.
• Crops needing nitrogen control (e.g., wheat, corn) may use low-nitrogen phosphate fertilizers.

2. Ammonium Bicarbonate (Carbon Ammonia)

Definition and Composition

Ammonium bicarbonate is a nitrogen (N)-based fertilizer, primarily composed of ammonium hydrogen carbonate. Nitrogen is vital for protein synthesis, chlorophyll formation, and photosynthesis.

Functions and Benefits

• Stimulates Early Growth: Particularly effective during seedling stages.
• Increases Yield and Quality: Optimal nitrogen levels enhance crop productivity and quality.
• Enhances Stress Resistance: Improves tolerance to cold, drought, and other stressors.

Application Methods

Applied in solid or liquid form, ammonium bicarbonate is chosen based on crop demands and soil conditions. For example:

• Nitrogen-intensive crops (e.g., cotton, soybeans) require high-nitrogen formulations.
• Crops needing nitrogen moderation (e.g., wheat, corn) may use lower-nitrogen versions.

3. Comprehensive Comparison

Complementary Roles

Phosphate and ammonium bicarbonate complement each other:

• Phosphate addresses phosphorus deficiencies in soil, boosting yields.
• Ammonium bicarbonate provides nitrogen for soils lacking this element.

Suitability Considerations

Soil pH and crop needs influence effectiveness:

• Acidic Soils: Lime can raise pH to prevent phosphorus lockup (due to calcium-phosphate precipitation).
• Alkaline Soils: Sulfur or limestone can lower pH to improve phosphorus availability (avoiding aluminum-phosphate binding).

Economic Efficiency

• Phosphate: Higher cost per unit but lower application rates, reducing overall expenses.
• Ammonium Bicarbonate: Cheaper but requires larger quantities, increasing per-hectare costs.

Both fertilizers have unique advantages. To optimize results, consider soil composition, crop type, application methods, and budget. Combining them strategically often yields the best outcomes.
