We reviewed the importance of N, N metabolism and plant growth, plant N physiology and the molecular aspect of N metabolism in this paper. The future development of N use and NUE of plants was also discussed.

3、A plan for efficient use of nitrogen fertilizers

A global analysis finds that nitrogen fertilizers could be used more efficiently if their international distribution across croplands was altered — a measure that would also decrease nitrogen...

4、Effects of Temperature and Soil Type on Ammonia Volatilization from Slow

These results indicate the composition of slow-release fertilizer, soil temperature, and soil type are main factors to dominate NH 3 volatilization from slow- release fertilizers.

Effects of types and application rates of nitrogen fertilizer on the development and nitrogen utilization of summer maize

To reduce nitrogen fertilizer (NF) loss and improve nitrogen use efficiency (NUE) in summer maize, the effects of the different application rates of three types of NF (urea, coated urea and compound fertilizer) on the growth and development and NUE of summer maize (cultivars: Zhengdan958 and Nongda108) were studied in 2004.

Slow

Currently there is interest in aggregating technology to fertilizers in order to increase their efficiency. A good example is the use of slow and steady release nitrogen fertilizers.

Regional distribution of nitrogen fertilizer use and N‐saving potential for improvement of food production and nitrogen use efficiency in China

BACKGROUND: An apparently large disparity still exists between developed and developing countries in historical trends of the amounts of nitrogen (N) fertilizers consumed, and the same situation holds true in China. The situation of either N overuse or underuse has become one of the major limiting factors in agricultural production and economic development in China. The issue of food security ...

Effect of different organic fertilizers application on growth and environmental risk of nitrate under a vegetable field

Results showed that organic fertilizers significantly increased vegetable yield and quality, but with inappropriate application may cause serious environmental risk such as nitrate pollution.

Comparison of yield and nitrogen use efficiency of different types of nitrogen fertilizers for different rice cropping systems under subtropical monsoon

Controlled release urea (CRU) and urea with nitrification inhibitor could improve yields and nitrogen use efficiency (NUE) in a number of production systems. However, their effectiveness will be strongly influenced by environmental conditions.

Effects of nitrogen

With the N-fertilizers levels of extractable soil Cd and plant Cd-contents were lowest in the nitrate of lime treatment, highest in the ammonium sulphate treatment and intermediate in the nitro-chalk treatment.

Clivia is a popular indoor foliage plant cherished for its elegant appearance and unique fragrance. To ensure healthy and vigorous growth, providing appropriate fertilization to meet its nutritional needs is essential. Below is a detailed introduction to the types of nitrogen fertilizers and their application methods for Clivia.

I. The Role and Types of Nitrogen Fertilizers

Nitrogen is a critical nutrient for plant growth, essential for leaf development and flower formation. It helps plants synthesize proteins, nucleic acids, and other vital substances, supporting normal physiological activities.

1. Urea Urea is a widely used nitrogen fertilizer that is easily absorbed by plants and suitable for various soil types. For application, dissolve urea in water and evenly spray it on the leaves or soil surface. Note: Excessive use may cause root burn, so adhere to proper dosage.

2. Potassium Nitrate (KNO₃) A composite fertilizer containing nitrogen, phosphorus, and potassium. Compared to single-nutrient fertilizers, it better meets the plant’s diverse nutritional needs. Mix with water and apply to leaves or soil. Its high potassium content also enhances disease resistance.

3. Potassium Dihydrogen Phosphate (KH₂PO₄) A highly efficient phosphorus-rich fertilizer that promotes root development and bud differentiation. Mix with water and apply to leaves or soil. Its potassium content also boosts disease resistance.

4. Compound Fertilizers These contain multiple nutrients and address the plant’s comprehensive needs. Select based on growth stages and soil tests. Note: Overuse may lead to salt accumulation or nutrient imbalance.

5. Organic Fertilizers Well-decomposed manure (e.g., cow dung, chicken manure) provides organic matter and microelements. Mix with water and apply to soil for slow-release nutrition. Organic fertilizers release nutrients gradually, requiring longer absorption time.

II. Fertilization Methods

1. Base Fertilization Incorporate organic fertilizers into the soil before planting to supply initial nutrients. This ensures adequate nutrition during early growth stages.

2. Topdressing Apply additional fertilizers during growth to replenish nutrients. Two types:

   • Slow-release topdressing: Used in the first 1–2 months after planting when nutrient demand is low.
   • Fast-acting topdressing: Targeted for specific growth stages or deficiencies, typically during rapid growth phases.

3. Foliar Spraying A quick method to address nutrient deficiencies. Use appropriate solutions and concentrations to avoid damage. Best performed during active growth stages for faster recovery.

III. Key Considerations

1. Avoid Overfertilization Excessive fertilization can cause root burn, yellowing leaves, or severe damage. Follow recommended dosages and frequencies.

2. Timing and Application

   • Nitrate fertilizers (e.g., KNO₃) are ideal during rapid growth.
   • Compound fertilizers suit base or topdressing applications.
   • Match fertilizer type to plant needs and soil conditions.

3. Avoid Mixing with Alkaline Fertilizers Some fertilizers react with alkaline soil components, reducing nutrient availability. Avoid combining acidic and alkaline fertilizers.

4. Monitor Plant Response Adjust fertilization based on the plant’s reaction. If symptoms occur (e.g., wilting, leaf discoloration), halt fertilization immediately and take remedial steps.

select nitrogen fertilizers and application methods based on Clivia’s growth stage and nutritional needs. Proper fertilization promotes lush leaves, vibrant flowers, and overall health. Pay attention to details during application to ensure optimal growth.
