1、Increasing double

Based on N release characteristics, CRNFs were categorized into four release modes: pre-positioned single-peak (PrSRM), post-positioned single-peak (PoSRM), decreasing double-peak (DDRM), and increasing double-peak (IDRM).

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

Modern agricultural practices rely heavily on nitrogen fertilizers since they enhance the growth of plants and maximize crop yields. It tackles different kinds of these fertilizers, highlighting their unique features and specific merits.

3、Effect of Different Form of N Fertilization on Yield Sustainability and

Through 10-year field trial we found that the application of different types of nitrogen fertilizers did not change SYI in double cropped rice system. Nevertheless, the application of different forms of nitrogen fertilizer could affect soil quality variables.

4、Effects of different new types of fertilizer on yield, nitrogen use

Conclusions Lignin slow-release fertilizer (5.5∶4.5) application can promote double-cropping rice to obtain high yield and high economic benefit, that is, improve the soil comprehensive fertility, and increase the utilization rate of nitrogen fertilizer, which is a recommended fertilization method.

5、Types of nitrogen fertilizers and their applications in agriculture

Slow-release nitrogen fertilizers can be classified into four types according to their agricultural chemical properties: synthetic organic nitrogen fertilizers, coated fertilizers, slow-dissolving inorganic fertilizers, and various ammonified fertilizers based on natural organic matter.

Nitrogen Fertilizer Types, Uses, and Benefits Explained

Nitrogen fertilizers can be divided up into two broad types, natural or synthetic. Natural N fertilizers are derived from nitrogen-rich substances such as manure, fish emulsions, or compost. Synthetic fertilizers are created in a lab by using N2 gas and transforming it into solid or liquid forms.

Effects of different types of nitrogen fertilizers on grain yield and

Compared with convention fertilizer (PU 100%), all treatments of controlled-release fertilizers as basal nitrogen fertilizer to single basal application had different performance on early and late rice.

All about nitrogen fertilizers

Ammonium nitrate is a highly concentrated nitrogen fertilizer containing about 34% nitrogen, half in the ammonium form and the other half as nitrates. This dual form provides plants with both quick-acting nutrition from nitrates and longer-term nitrogen supply via the ammonium form.

Therefore, we investigated the effects of these three types of N fertilizer on rice grain yield, apparent N recovery efficiency (ANR), and soil chemical properties in a double cropped rice system over a 7-year period in Zhejiang Province, China.

Double-nitrogen fertilizers, which contain two forms of nitrogen, typically refer to urea and ammonium nitrate. These fertilizers are widely used in agricultural production because they provide the nitrogen essential for plant growth. Below is a detailed introduction to the types, characteristics, and applications of these two fertilizers in agriculture:

1. Urea

• Composition: Urea is the simplest binary nitrogen fertilizer, composed of carbon, hydrogen, oxygen, and nitrogen. It is produced by reacting ammonia (NH₃) with carbon dioxide (CO₂).
• Physical Properties: Urea is a white crystalline or powdery substance that is highly soluble in water. Its solubility increases with temperature.
• Nitrogen Content: Urea has a high nitrogen content (46%), making it an efficient nitrogen source. It provides rapidly available nitrogen, suitable for use as both base fertilizer and topdressing.
• Applications: Urea is applicable to various crops, including grains, vegetables, and fruit trees. It significantly improves crop yield, quality, and stress resistance.
• Considerations: While urea enhances soil nitrogen levels and promotes crop growth, excessive use may lead to soil acidification and salinization, affecting soil structure. rational dosage and proportioning are critical.

2. Ammonium Nitrate

• Composition: Ammonium nitrate is a binary compound composed of nitrogen, hydrogen, and oxygen. It is synthesized by reacting ammonia (NH₃) with oxygen (O₂).
• Physical Properties: Ammonium nitrate is a white, granular, or crystalline solid that is highly soluble in water. Its solubility increases with temperature.
• Nitrogen Content: Ammonium nitrate has a moderate nitrogen content (34%) and provides nitrogen at a medium-release rate. It is particularly suitable for crops requiring slow-release nitrogen.
• Applications: Ammonium nitrate is effective for various crops, including grains, cash crops, fruits, and vegetables. It improves yield, quality, and stress resistance.
• Considerations: Excessive use of ammonium nitrate may cause soil salinization and degrade soil quality. Rational dosage and proportioning are essential to avoid these issues.

Other Binary Nitrogen Fertilizers

In addition to urea and ammonium nitrate, other binary nitrogen fertilizers include:

• Ammonium Dihydrogen Phosphate (DPA): A white, water-soluble crystalline or granular solid. It contains both nitrogen and phosphorus, addressing dual nutrient needs in crops.
• Diammonium Hydrogen Phosphate (DP₂O₄): A white, water-soluble solid that provides both nitrogen and phosphorus.
• Ammonium Monophosphate (P₁₀₀): A white, water-soluble solid rich in phosphorus, suitable for crops requiring phosphorus.

These fertilizers are widely used in agriculture, but their specific applications vary by region and crop type.

Double-nitrogen fertilizers are indispensable in agricultural production, supplying essential nitrogen for crops. When selecting and applying these fertilizers, factors such as crop type, soil conditions, and climate should be considered to ensure proper dosage and methods. Rational use is crucial to avoid soil pollution and resource waste.
