1、Slow

High nitrogen (N) losses and low nitrogen utilisation efficiency (NUE) of conventional-nitrogen fertilisers (CNFs) are due to a mismatch between N-delivery and plant demand; thus, slow-release N fertilisers (SRNFs) are designed to improve the match.

2、Effects of stabilized nitrogen fertilizer reduction on nitrogen uptake

Stabilized nitrogen fertilizers have showed acknowledged effects in yield increasing and nitrogen input reduction, but lack the targeted recommendation for different soil and climatic conditions.

4、Research, production and use of stabilized fertilizers in China

Meta-analysis of over 900 trials (2014–2018) demonstrates stabilized fertilizers increase yields by 9.2%, nitrogen use efficiency by 11.2% and lower N2O emissions by 28.4% in staple crops.

A review on slow

Most of these conventional fertilizers are inefficient as they are readily water-soluble and quickly dissolve in the irrigation water or soil moisture, yielding excessive concentrations of the nutrients in the root zone, which the plants cannot uptake.

(PDF) Positive and Negative Impact of Nitrogen Fertilizer on Soil

This study found that excessive nitrogen fertilization had negative impact on soil health factors such as bulk density increment and carbon content decline through deeper profiles.

Comparing Slow

In this article, we will explore the key aspects of slow-release versus quick-release nitrogen fertilizers, comparing their mechanisms, benefits, drawbacks, and application scenarios.

Enhanced Efficiency Fertilizer Materials: Nitrogen Stabilizers

Stabilized fertilizers – Products claiming stabiliza-tion of nutrients must reduce the transformation rate of fertilizer compound(s), extending the time of nutrient availability to the plant by a variety of mechanisms relative to its unamended form.

Novel Fertilizer Technologies and their modes of action

Nitrogen fertilizers are prone to losses via leaching, runoff, volatilization, and microbial immobilization. Technologies such as inhibitor-treated fertilizers and controlled-release products are designed to reduce these losses and enhance efficiency.

Nitrogen Fertilization. A Review of the Risks Associated with the

Nearly half of N fertilizer input is not used by crops and is lost into the environment via emission of gases or by polluting water bodies. It is essential to achieve production levels, which enable global food security, without compromising environmental security.

Nitrogen fertilizers are indispensable in agricultural production, providing plants with one of the essential nutrients—nitrogen. They play a crucial role in improving crop yields and enhancing quality. stabilized nitrogen fertilizers also have certain drawbacks that may affect their effectiveness and economic benefits. The following section explores these disadvantages in detail:

1. Higher Costs

Stabilized nitrogen fertilizers are typically more expensive. Their production involves stringent quality control and stabilization processes to ensure product stability and safety, leading to higher manufacturing costs. This places a greater financial burden on farmers when purchasing and using these fertilizers.

2. Environmental Impact

Stabilized nitrogen fertilizers may harm the environment during production and application. For instance, improper handling during manufacturing could result in nitrogen volatilization or leakage into the environment, causing pollution. Excessive use may also lead to soil acidification and groundwater contamination.

3. Resource Waste

Due to their high stability, these fertilizers are less prone to volatilization or runoff, potentially requiring increased application rates. This could result in resource waste and reduced fertilizer efficiency. Overapplication might also disrupt soil nutrient balance, exacerbating resource inefficiency.

4. Uneven Fertilization

Stabilized nitrogen fertilizers often have poor solubility, leading to crystallization and precipitation in soils. This can cause uneven nutrient distribution, with some areas lacking nitrogen while others experience excess, negatively impacting crop growth and potentially reducing yields.

5. Difficult Dose Control

Their low solubility makes it challenging for farmers to precisely control application rates. This may result in over- or under-fertilization, affecting crop growth and productivity. Additionally, unfamiliarity with proper usage techniques could further diminish effectiveness.

6. Soil Microbial Activity Impact

The stability of these fertilizers reduces their availability for decomposition by soil microorganisms, potentially suppressing microbial activity. This could impair soil fertility and ecological balance. Long-term heavy use might also cause soil compaction and degradation.

7. Crop Quality Effects

While stabilized nitrogen fertilizers boost crop yields, excessive use may compromise quality. For example, overapplication can lead to nitrate accumulation in plants, altering fruit taste and nutritional value. Prolonged reliance on such fertilizers might also reduce crop resilience to pests and diseases.

8. Persistence in Environment

Stabilized nitrogen fertilizers degrade slowly in natural environments, posing long-term soil health risks. Excessive use could contribute to soil acidification, heavy metal contamination, and other issues, threatening ecosystems and human health.

Stabilized nitrogen fertilizers have limitations, including high costs, environmental harm, and resource inefficiency. To address these challenges, the following measures are recommended:

1. Optimize production processes to lower costs and improve cost-effectiveness.
2. Enhance environmental awareness to minimize pollution during manufacturing.
3. Apply rationally to avoid overuse and maintain nutrient balance.
4. Promote scientific fertilization methods to boost efficiency and reduce waste.
5. Advance research on alternative, eco-friendly fertilizers.
6. Improve soil management to restore microbial activity and fertility.
7. Strengthen environmental protection efforts to mitigate ecological damage.

By implementing these strategies, the disadvantages of stabilized nitrogen fertilizers can be effectively addressed, enhancing their overall benefits in agriculture.
