1、Overcoming nitrogen fertilizer over

Over-application and inefficient use of nitrogen (N) fertilizer is a serious issue throughout China, with adverse environmental and economic impacts. In this paper we present evidence of this in the wheat/maize double cropping system in the Guanzhong Plain in Shaanxi Province, northwest China.

2、How To Adjust Fertilizer With Too Much Nitrogen

To remedy excess nitrogen, limit nitrogen-based fertilizers, use organic compost or mulch, and consider planting nitrogen-fixing species. Additionally, soaking the soil can help mitigate nitrogen levels.

3、Higher yield with less nitrogen fertilizer

Excess N and its associated negative environmental effects has become a global concern, hence researchers aim to develop efficient strategies such as increasing plant nitrogen use efficiency...

Excessive use of nitrogen in Chinese agriculture results in high N2O

We hypothesized that this would enhance the soils’ propensity to emit N2O from denitrification by reducing the expression of the enzyme N2O reductase. We investigated this by standardized oxic/ anoxic incubations of soils from five long-term fertilization experiments in different regions of China.

Excessive Nitrogen Fertilizer Application Causes Rapid Degradation of

To reclaim the degraded soil with high nitrate concentration, an economical and environmentally friendly approach by incorporation of appropriate amount of plant materials with high C/N ratio into the soil was discussed. It was demonstrated that biomass addition could promote humification of nitrate with the help of microorganisms.

Excessive Nitrogen Fertilizer Application Causes Rapid

To maintain good productivity, a large quantity of fertilizers was continuously applied to the soil. Due to low nitrogen (N) use efficiency, excessive nutrients are accumulated in soil profile. As a result, greenhouse soil is often compromised by the secondary soil salinization.

Study on N application and N reduction potential of farmland

Ensuring food production and rationalizing the use of agricultural resources require addressing the problem of the improper application of chemical fertilizers. Several effective measures have been implemented in China to reduce agricultural non-point source pollution.

Soil Acidification caused by excessive application of nitrogen

Among the complex soil chemical factors, the increase in available nitrogen (AN) caused by excessive application of nitrogen fertilizer and the accumulation of phenolic acids were the main driving factors for the decrease in the soil pH value.

Response of Nitrogen Losses to Excessive Nitrogen Fertilizer

We conducted a meta-analysis using 1174 paired observations from 69 publications on the effects of nitrogen fertilizer application and reducing nitrogen fertilizer application on the nitrogen losses on a broad scale.

How to Reduce Nitrogen Fertilizer Usage and Increase Soil Health

Excess nitrogen fertilizer is not only damaging to the environment, but can also waste significant resources for farmers. In this blog we talk about strategies to lower nitrogen usage, leading to a healthier ecosystem and more profit for growers.

Excessive use of nitrogen fertilizer can lead to rapid crop growth, weak stems, dark green leaves, and nutrient imbalance within plants. This increases susceptibility to lodging and reduces stress resistance. rational nitrogen application is critical for improving yield and quality in agricultural production. If nitrogen fertilizer is overused, the following measures can help mitigate the impact:

1. Deep Soil Loosening: Loosening the soil to a depth of 20–30 cm allows excess fertilizer to penetrate deeper layers, reducing surface nutrient loss.

2. Adjust Sowing Date: Delaying sowing provides crops with additional time to absorb soil nutrients, minimizing nitrogen leaching.

3. Increase Phosphate and Potassium Fertilizers: These enhance disease resistance, promote root development, and improve nitrogen uptake efficiency.

4. Irrigate Appropriately: Moderate irrigation maintains soil moisture, reduces evaporation, and stabilizes nitrogen retention.

5. Grow Green Manure: Planting green manure enriches soil organic matter, boosts water/nutrient retention, and reduces nitrogen runoff.

6. Practice Crop Rotation: Rotation reduces pest/disease risks, improves soil fertility, and minimizes nitrogen loss.

7. Use Slow-Release Nitrogen Fertilizers: These formulations delay nitrogen release, cutting losses.

8. Add Organic Fertilizers: Organic matter improves soil structure, enhances fertility, and reduces nitrogen leaching.

9. Apply Fertilizers Reasonably: Tailor nitrogen application to crop needs and soil conditions to avoid overuse.

10. Timely Topdressing: For excessive nitrogen cases, supplement with balanced topdressing to correct nutrient imbalances.

11. Control Nitrogen Dosage: Adjust nitrogen amounts based on crop cycles and soil tests to prevent overapplication.

12. Apply Microbial Fertilizers: These promote beneficial soil microorganisms, enhancing fertility and nitrogen retention.

13. Adopt Conservation Tillage: Minimize soil erosion and runoff to reduce nitrogen loss.

14. Strengthen Field Management: Timely weeding, soil aeration, and proper irrigation reduce nitrogen depletion.

15. Use Mulch Coverings: Straw or rice husk mulch prevents water/wind erosion, safeguarding nitrogen.

These strategies effectively counteract the negative effects of excessive nitrogen use, ensuring healthy crop growth. Farmers should prioritize scientific fertilization, balancing nitrogen with phosphorus, potassium, and other essential nutrients to optimize plant nutrition.
