1、Tipping The Balance

In this amine form, there’s supply of a more efficient form of nitrogen. The nitrogen supplied is more energy-efficient with less carbon used, as it doesn’t require conversion to ammonium before the plant can utilize it. The amine form also encourages more reproductive growth.

2、Understanding the Benefits of Amines in Biofertilizers

Unlike chemical fertilizers that often require multiple applications throughout the growing season, amines in biofertilizers can have a lasting impact on soil fertility and nutrient availability.

3、Unlocking nitrogen

The review highlights the potential of nitrogen-rich biomass, such as algae and protein-derived materials, for sustainable production of nitrogen-containing chemicals via chemo-catalytic pathways.

Use of Stabilised Amine Nitrogen (SAN) Reduces Required Nitrogen Input

The production of onions (Allium cepa) results in low nitrogen use efficiency (NUE) as nitrogen is applied when it is not required by the plant; resulting in loss to the environment.

All About Nitrogen Fertilizers: Types, Benefits, and Application Tips

Q: Are there differences in effectiveness between organic and synthetic nitrogen fertilizers? A: Organic nitrogen fertilizers release nutrients more slowly and improve soil health over time, whereas synthetic nitrogen fertilizers provide an immediate nutrient boost.

Classification of nitrogen fertilizers

Nitrate synthesis by arc-gap process Nitrogen fertilizers are produced essentially via ammonia synthesis with ammonia being further processed in to various nitrogenous fertilizers.

Organic Nitrogen Compounds: Amines

One of the primary uses of amines is in the production of fertilizers as ammonium salts, the acidic form of the amine. These fertilizers are water soluble and readily absorbed by the soil. Crops like rice and sugarcane directly utilize the ammonium form of these fertilizers.

Fertilizers: Nitrogen Fertilizers

This form of fertilizer nitrogen usually undergoes a three-step change before it is taken up by crops. First, enzymes in the soil or plant residue convert the urea nitrogen to ammonia nitrogen (NH3).

Nitrogen Fertilizers: Types, Benefits, And Application Tips

Without this natural gas, we cannot make nitrogen-based fertilizers; our only option is to use its limited resources for farming. Nitrogen fertilizers typically come in one of these forms: nitrate (NO3), ammonia (NH3), ammonium (NH4), or urea (CH4N2O).

The "three amines," typically referring to urea, ammonium formate, and ammonium acetate, are widely used in agriculture as nitrogen-containing compounds. despite containing nitrogen, they are not considered traditional nitrogen fertilizers for the following reasons:

1. Definitional Differences

• Nitrogen Fertilizers: These are fertilizers designed to provide plants with nitrogen. Common examples include urea, ammonium nitrate (a salt formed by reacting ammonia with nitric acid), and ammonium chloride (a salt formed by reacting ammonia with chlorine gas). They promote plant growth and crop yields by supplying nitrogen.
• The Three Amines: While urea, ammonium formate, and ammonium acetate all contain nitrogen, they are not classified as traditional nitrogen fertilizers due to differences in their chemical properties and mechanisms of action.

2. Chemical Properties

• Urea: A organic compound composed of carbon, hydrogen, oxygen, and nitrogen (chemical formula: CO(NH₂)₂). It has low water solubility and requires heating or alkaline substances (e.g., lime water) to improve dissolution. Urea can act as a nitrogen fertilizer because it contains plant-absorbable nitrogen.
• Ammonium Formate: An organic compound with the formula C₃H₇N₂O₂. It is highly water-soluble and easily absorbed. Its molecular structure includes a carboxyl group (-COOH), allowing it to neutralize acidic substances in soil, reducing soil acidification. Under specific conditions, it can function as a nitrogen fertilizer.
• Ammonium Acetate: An organic compound with the formula C₄H₈N₂O₂. It is also highly water-soluble and absorbable. Like ammonium formate, it contains a carboxyl group (-COOH) that neutralizes soil acids, reducing acidification. In some cases, it can be used as a nitrogen fertilizer.

3. Mechanisms of Action

• Urea: Primarily provides nitrogen to promote plant growth and crop yields. It is absorbed by plant roots and converted into amino acids or other nitrogen-containing compounds for use.
• Ammonium Formate: Shares a similar mechanism to urea but with higher water solubility. It neutralizes soil acids, reducing acidification, and can act as a slow-release nitrogen fertilizer by gradually releasing nitrogen to meet plant demands.
• Ammonium Acetate: Functions similarly to urea but with higher solubility. It neutralizes soil acids and can serve as a slow-release nitrogen fertilizer, releasing nitrogen slowly to support plant growth.

4. Application Range

• Urea: One of the most widely used nitrogen fertilizers, applicable to various crops. It can be used alone or mixed with other fertilizers to enhance efficacy.
• Ammonium Formate: Used selectively, such as in acidic soils to reduce acidification. its frequency and dosage must be carefully managed to avoid exacerbating soil acidity.
• Ammonium Acetate: Primarily used in pharmaceutical intermediate production rather than as a nitrogen fertilizer, making its agricultural applications limited.

5. Summary

Though the three amines contain nitrogen, their chemical properties and mechanisms differ from traditional nitrogen fertilizers. under specific conditions—such as in acidic soils—they can still serve as nitrogen sources while mitigating soil acidification.

6. Precautions

• When using the three amines as nitrogen fertilizers, control dosage and application methods to avoid excessive soil acidification. Select appropriate products based on crop type and soil conditions for optimal results.
• Follow scientific fertilization principles, balance with other nutrients, and protect the environment to prevent soil or water pollution.
