1、Nitrogen assimilation in plants: current status and future prospects

To increase grain yields, large amounts of fertilizers, especially nitrogen (N) fertilizers, are applied during agricultural production; however, only 30%–50% of the applied N fertilizers could be absorbed and incorporated into crops (Raun and Johnson, 1999).

2、Crop nitrogen (N) utilization mechanism and strategies to improve N use

In this review, we discussed the molecular, biochemical, and enzymatic mechanisms involved in NUE in crop plants, ways to increase NUE through the identification of plant factors with special consideration of their interaction, and different management strategies.

3、Soil nitrogen fertilization reduces relative leaf nitrogen allocation

Here, we examined the physiological responses of a non-nitrogen-fixing plant (Gossypium hirsutum) and a nitrogen-fixing plant (Glycine max) in a fully factorial combination of light by soil nitrogen availability to help reconcile these competing hypotheses.

Leaf N content increases when N fertilizer is applied. Higher N content in leaves is associated with higher chlorophyll content and increased chloroplast activity and thus increased...

The Succulent Fertilizer Guidebook

After the dirt is wet, dilute the succulent fertilizer with water and pour the mixture into the soil until it drains through drainage holes. If fertilizers are pellets, spray them evenly on the soil and water. Make sure the pellets you use are the slow-release type.

Best Fertilizers to Use After Plant Fragmentation Propagation

By using diluted liquid fertilizers with appropriate NPK ratios, waiting for root initiation before feeding, and adjusting application rates as plants grow stronger, gardeners can ensure their propagated fragments develop into robust mature plants ready to thrive in garden beds or containers.

Effect of nitrogen, phosphorus and potassium fertilization management

At the P2K2 level, leaf area index, chlorophyll, starch, phosphorus content indicators under each fertilization treatment showed a trend of increasing and then decreasing with the addition of nitrogen application, and reached the highest value in the N2P2K2 treatment, and soluble sugar, nitrogen, and potassium content showed a gradual increase ...

Effect of nitrogen application levels on photosynthetic nitrogen

Although legumes can fix nitrogen biologically, the application of nitrogen fertilizers is necessary to obtain strong seedlings, as root nodules are not formed at the seedling stage and nitrogenase is inactive (Cruz et al., 2003).

Effects of Foliar Fertilization: a Review of Current Status and Future

Foliar fertilizer application after soil fertilization is an effective method to increase the contents of trace elements in crops and crop yield, and to improve the soil environment. However, the application of inorganic foliar fertilizer results in difficulties in nutrient absorption and migration in plants.

Water availability and nitrogen use in plants: effects, interaction

Nitrogen use efficiency (NUE) in crops remains low despite significant research efforts, which has led to the excessive usage of N fertilizer and resulted in economic losses and environmental pollution.

Applying an appropriate amount of nitrogen fertilizer is crucial for the growth of leaf-propagated succulent seedlings. Nitrogen, one of the essential nutrients for plant growth, plays a particularly important role in succulents. It promotes growth, increases leaf quantity and thickness, and enhances the ornamental value of the plants. Below is a detailed guide on applying nitrogen fertilizer to succulent leaf-propagated seedlings.

The Role of Nitrogen Fertilizer

1. Promotes Growth: Nitrogen is an essential nutrient for plant development, stimulating stem and leaf growth in succulents.
2. Enhances Photosynthesis: Nitrogen improves photosynthetic efficiency in leaves, contributing to healthier plants.
3. Improves Quality: Proper nitrogen application enhances color, gloss, and overall vitality, making succulents appear fuller and more vibrant.

Methods for Applying Nitrogen Fertilizer

1. Choosing the Right Nitrogen Source

• Urea: A common nitrogen fertilizer suitable for nitrogen-demanding succulents.
• Monammonium Phosphate: Provides nitrogen, phosphorus, and potassium, promoting balanced growth.
• Calcium Nitrate: High-nitrogen content for rapid nutrient supplementation.

2. Timing of Application

• Growing Season: Spring and summer are peak growth periods. Nitrogen fertilizer accelerates growth during these times.
• Dormant Period: In autumn and winter, reduce or暂停 nitrogen use. Excessive growth during dormancy may harm flowering potential.

3. Application Methods

• Base Fertilization: Mix nitrogen-rich fertilizer into the soil during initial planting for sustained nutrient release.
• Topdressing: During the growing season, apply nitrogen fertilizer every 2–4 weeks based on growth conditions. Avoid over- or under-fertilization.

4. Key Considerations

• Avoid Over-Fertilization: Excess nitrogen causes rapid, weak growth. Use precise amounts.
• Application Technique: Spread fertilizer evenly around the base of the plant, avoiding direct contact with leaves (to prevent burns) and roots (to reduce rot risk).

Nitrogen fertilizer is beneficial for succulent leaf-propagated seedlings when used correctly. Proper timing and dosage enhance growth, leaf density, and aesthetic appeal. excessive application can harm plants, so careful attention to quantity and frequency is essential.
