1、Optimal nitrogen management to achieve high wheat grain yield, grain

Among the common N fertilizers, solo urea performed better than ammonia nitrate and urea combined ammonia nitrate in term of yield increase, with an optimal rate of 39.01% (lnR 0.49), 23.49% (lnR 0.27), and 7.611% (lnR 0.08), respectively.

3、Impact of Various Nitrogenous Fertilizers on Wheat Crop Yield and

wheat. This study assessed the effects of different nitrogen fertilizers (Urea, Ammonium Nitrate, Ammonium Sulfate, and Calcium Ammonium Nitrate) on wheat growth and yield.

Relative Efficacy of Liquid Nitrogen Fertilizers in Dryland Spring Wheat

The study was conducted in 2012 and 2013 at three locations in North Central and Western Montana (total of 6 site-years) to evaluate the relative efficacy of three liquid nitrogen (N) fertilizer sources, urea ammonium nitrate (UAN, 32-0-0), liquid urea (LU, 21-0-0), and High NRGN (HNRGN, 27-0-0-1S), in spring wheat (Triticum aestivum L.).

Combining Organic Fertilizer With Controlled

When urea is used as basal fertilization, the available N is rapidly mineralized for wheat, but less than half of the total N is effectively utilized and leftover has a negative ecological effect by leaching (Galloway et al., 2008).

The Impact of Urea Nitrogen Fertilizers on Wheat Growth

This article explores the effects of urea nitrogen fertilizers on wheat cultivation, focusing on appropriate application scenarios and solutions to optimize fertilizer use for healthy growth and improved yields.

Urea vs Other Nitrogen Fertilizers

Drawing on exposure to diverse fertilization programs and real supply-chain requirements, this article analyzes urea vs other nitrogen fertilizers from a practical standpoint, helping readers evaluate performance differences and make informed nutrient management decisions using urea fertilizer.

Wheat: Spring Nitrogen Management

The differences in price between urea and liquid nitrogen frequently sways the producer towards one form of N or the other for obvious reasons. If the product selected can be distributed uniformly and accurately across the wheat fields, then go with the cheapest product.

Alteration of Nitrogen Fertilizer Forms Optimizes Nitrogen

In recent years, integrated water and fertilizer management has significantly improved winter wheat yield and nitrogen use efficiency; however, quantitative assessments of nitrogen cycling under different fertilizer forms in such high-yield systems remain limited.

Liquid vs Granular Urea: Which One to Choose?

Choosing liquid vs granular urea fertilizer isn’t about which is better — it’s about which is right for your field, your timing, and your goals. Both have a place in agriculture.

In modern agricultural production, selecting the appropriate fertilizer is crucial for improving crop yield and quality. Urea and liquid nitrogen fertilizer are two commonly used chemical fertilizers that play important roles in agriculture. This article compares the effects of urea and liquid nitrogen fertilizer from multiple perspectives to help farmers make more informed decisions.

I. Composition and Properties

1. Urea

• Chemical Nature: Urea is a white, water-soluble crystalline compound with the chemical formula CO(NH₂)₂.
• Primary Use: It mainly provides nitrogen (N) required for plant growth and promotes protein synthesis.
• Advantages: Easy to store and transport, relatively low cost, and less environmental impact.
• Disadvantages: During decomposition, urea releases ammonia (NH₃), which may cause soil salinization. Excessive use can lead to nitrogen overload in the soil, inhibiting plant growth.

2. Liquid Nitrogen Fertilizer

• Chemical Nature: A colorless gas primarily composed of nitrogen (N₂), known for its high thermal stability and chemical inertness.
• Primary Use: Rapidly replenishes nitrogen in plants, suitable for scenarios requiring immediate nitrogen supply.
• Advantages: Quickly absorbed by plants, improving nitrogen utilization efficiency. Flexible application methods allow precise fertilization based on crop needs.
• Disadvantages: Higher cost and greater environmental impact. Improper application may damage crops (e.g., burning leaves).

II. Suitability for Different Scenarios

1. Urea

• Ideal Crops: Suitable for most crops, especially legumes, which form stable nitrogen complexes with urea, enhancing efficiency.
• Application Conditions: Preferred in low-fertility soils or when rapid nitrogen supplementation is needed.

2. Liquid Nitrogen Fertilizer

• Ideal Crops: Suitable for crops requiring quick nitrogen uptake, such as rice, wheat, and other high-yield grains.
• Application Conditions: More effective in low-fertility soils or when immediate nitrogen supply is critical.

III. Economic Considerations

1. Urea

• Cost: Lower price and widely available.
• Economic Efficiency: Simple application methods may reduce actual efficiency, potentially affecting long-term profitability.

2. Liquid Nitrogen Fertilizer

• Cost: Higher upfront cost and requires specialized equipment/techniques for application.
• Economic Efficiency: Precision fertilization improves nitrogen use efficiency, offering better long-term economic returns despite higher initial costs.

IV. Environmental Impact

1. Urea

• Environmental Friendliness: No harmful gases are released during decomposition, minimizing ecological harm.
• Sustainability: Lower application rates reduce agricultural waste and pollution risks.

2. Liquid Nitrogen Fertilizer

• Environmental Risks: Potential for crop damage (e.g., leaf burning) and soil nitrogen overload, which can exacerbate environmental pollution.
• Sustainability: Higher costs and environmental toll limit its long-term sustainability despite flexibility.

Farmers should choose between urea and liquid nitrogen fertilizer based on soil conditions, crop requirements, and sustainability goals. Urea is recommended for low-fertility soils or rapid nitrogen needs, while liquid nitrogen fertilizer suits high-demand crops or precise nutrient management. Prioritizing eco-friendly options ensures sustainable agricultural development.
