1、Nitrogen (N) “supplementation, slow release, and retention” strategy
Correlation analyses showed that the increase in soil N 2 fixation and the suppression of nitrification and denitrification reactions were the key contributors to the increase in soil N content and NUE.
2、Effects of rainfall amount and frequencies on soil net nitrogen
Global climate change has led to a significant increase in the frequency of extreme rainfall events in the Qinghai-Tibetan Plateau (QTP), thus potentially increasing the annual rainfall amounts...
3、Synergistic Effects of Nitrogen Application Enhance Drought Resistance
These findings highlight that nitrogen supplementation, particularly mixed nitrogen application, enhances drought resistance in M. yunnanensis, offering a viable management strategy to sustain urban tree landscapes in water-limited environments.
4、Nitrate dynamics and source identification of rainwater in Beijing
As one of the most important sinks of atmospheric nitrogen, the wet deposition of nitrate (rainwater NO 3-) has been widely concerned. Yet, the sources and transformation processes of wet deposited NO 3- were not well revealed in megacity during rainy season in the context of global climate change.
5、Nitrogen addition amplified water effects on species composition shift
Nitrogen addition significantly increased community ANPP with greater increase in PR under summer rainfall addition, indicating strong interactive effects on community ANPP largely by enhancing PR biomass.
Supplementary irrigation and reduced nitrogen application improve the
Supplementary irrigation improved the yields and resource use efficiency of the intercropping system. Reduced nitrogen application did not decrease the yield and resource use advantage of intercropping. The yield advantage of the intercropping was from the complementarity and selection effects.
Effectiveness of bioretention system with saturated zone and different
By prioritizing microbial niche differentiation over soil adsorption, this work resolves the paradox of nitrate pollution in carbon-limited stormwater, offering a mechanistic blueprint for adaptive, carbon–neutral BRSs—a critical advance for eutrophication mitigation.
Nitrogen (N) “supplementation, slow release, and retention
Irrational nitrogen (N) fertilizer management and application practices have led to a range of ecological and environmental problems that seriously threaten food security.
Effectiveness of Nutrient Management on Water Quality Improvement: A
Yet, due to complex processes and mechanisms in nutrient cycling (especially the nitrogen (N) cycle), there are many challenges in evaluating the effectiveness of nutrient management practices across site conditions.

Analysis of the Effects and Rationale Behind Rainwater Nitrogen Supplementation
I. Concept of Rainwater Nitrogen Supplementation Rainwater nitrogen supplementation refers to the practice of applying an appropriate amount of nitrogen fertilizer to the soil through artificial or natural rainfall. This method aims to promote plant growth and development. It is considered an ideal organic fertilizer supplementation approach due to its low cost, effectiveness, and environmental friendliness.
II. Effects of Rainwater Nitrogen Supplementation
- Enhancing Soil Fertility: By increasing the nitrogen content in the soil, this method boosts soil fertility, providing plants with ample essential nutrients. This promotes healthier growth, higher yields, and improved crop quality.
- Improving Soil Structure: Rainwater nitrogen supplementation helps loosen and aerate the soil, creating an optimal environment for root development and nutrient absorption. This enhances water and nutrient utilization efficiency while reducing the risk of pests and diseases.
- Reducing Production Costs: Eliminating the need for chemical fertilizer purchases, this method relies solely on rainwater for fertilization, significantly lowering production costs and minimizing environmental pollution.
- Boosting Crop Yield and Quality: Nitrogen is a critical nutrient for plant growth. Rainwater nitrogen supplementation ensures a steady supply of nitrogen, directly contributing to higher yields and superior crop quality.
- Promoting Ecological Balance: By reducing reliance on chemical fertilizers, this practice minimizes environmental pollution. Additionally, since nitrogen is decomposed naturally in rainwater, it avoids secondary ecological harm, supporting long-term ecological balance.
III. Rationale Behind Rainwater Nitrogen Supplementation
- Resource Conservation: As a green, pollution-free method, it eliminates the need for chemical fertilizers, reducing both costs and environmental damage.
- Environmental Protection: This approach generates no chemical pollutants, preventing secondary pollution. The natural decomposition of nitrogen in rainwater also safeguards water sources.
- Crop Yield and Quality Improvement: By ensuring a consistent nitrogen supply, rainwater nitrogen supplementation addresses a key nutritional requirement for plants, directly enhancing yield and quality.
- Ecological Balance Support: Reducing chemical fertilizer use mitigates environmental harm, while the natural breakdown of nitrogen in rainwater prevents ecological disruption, fostering sustainable balance.
Rainwater nitrogen supplementation is a simple, economical, and eco-friendly fertilization method. Its advantages include low cost, high effectiveness, and environmental sustainability. By improving soil fertility, optimizing soil structure, reducing production costs, and enhancing crop quality, it also contributes to ecological balance. To achieve sustainable agricultural development, this practice should be actively promoted.
