1、农田氮肥残留效应及其影响因素

The recovery and utilization of residual nitrogen fertilizer are influenced by multiple factors such as its own migration and transformation, crop types, soil fertility conditions, climate environment and tillage management.

2、Effects of residue management and nitrogen fertilizer rates on

Conservation tillage, residue management and optimizing nitrogen (N) fertilization are important strategies for soil and water conservation and sustainability of agricultural systems.

3、The Effect of Soil Microbial Residues

Microbial residue nitrogen can indicate soil quality and is crucial for soil nitrogen retention and supply. However, it is still unclear how the dynamic changes in soil microbial residue nitrogen affect crop nitrogen uptake in agricultural practice.

4、Effects of Fertilizer Nitrogen Reduction and Crop Residue Return on

At all N fertilizer levels, crop residue return, especially full crop residue return, was beneficial to alleviating the release of fixed NH₄⁺, but the crop residue effect was weaker under N135 treatment.

Integrating nitrogen fertilization with crop residues to improve

Global consumption of N fertilizers is increasing to meet the demand of food security with the limited natural resources. The FAO (2018) has predicted that, by 2050, worldwide use of N fertilizers is expected to increase by 50%.

Residual effect of nitrogen fertilizer and its influencing factors in

The fate of fertilizer nitrogen, the amount, distribution, utilization and influencing factors of nitrogen fertilizer residues were reviewed in this paper. Based on the current research progress, the future research highlight and the implications of related research on agricultural management practice were proposed.

Nitrogen fertilizer is a critical agricultural input that contains nitrogen, an essential element for promoting plant growth. its excessive use has raised concerns. Below is a detailed analysis of the advantages and disadvantages of nitrogen-containing fertilizer residues:

Benefits:

1. Enhancing Soil Fertility: Nitrogen fertilizer increases soil nitrogen content, boosting soil fertility. This improves soil structure, water retention capacity, and air permeability, fostering healthier root systems.
2. Promoting Plant Growth: Nitrogen provides essential nutrients for plant development, which is vital for agriculture since plants form the foundation of the food chain and human sustenance.
3. Increasing Crop Yields: By stimulating photosynthesis and biomass production, nitrogen fertilizer directly enhances crop output.
4. Resource Conservation: Scientific application of nitrogen fertilizers, such as precision farming, reduces usage and minimizes environmental pollution risks.
5. Economic Benefits: Proper nitrogen management raises agricultural profitability by increasing yields and farmers’ income, thereby driving industry growth.

Drawbacks:

1. Environmental Pollution: Excessive nitrogen use leads to harmful byproducts like ammonia gas and nitrates, contaminating air, water, and soil. Runoff also contributes to soil degradation and water scarcity.
2. Soil Acidification: Long-term overuse acidifies soil, diminishing its fertility and structure. This promotes toxic heavy metal accumulation, posing ecological and health hazards.
3. Groundwater Contamination: Nitrogen runoff seeps into aquifers, degrading drinking water quality.
4. Ecological Disruption: Overapplication disrupts ecosystems by favoring certain plants over others, upending natural balance.
5. Waste of Resources: Unregulated nitrogen use inflates production costs and squanders fertilizer resources.

While nitrogen-containing fertilizer residues offer benefits like improved soil health and crop productivity, they also pose significant environmental and ecological risks. To balance these effects, scientifically sound practices are essential to maximize fertility and crop yields while minimizing harm to the environment and conserving resources.
