Deep placement of nitrogen fertilizer (DPNF) is an agronomic measure that shows promise in addressing these issues. This review aims to offer a comprehensive understanding of DPNF, beginning with a succinct overview of its development and methodologies for implementation.

Optimizing Nitrogen and Phosphorus Fertilizer Application for Wheat

Enhancing crop productivity on alkali soils is essential for food security; however, excessive fertilizer use can lead to soil salinization. Wheat, as a key staple crop, requires an appropriate nitrogen-to-phosphorus fertilization ratio to optimize its yield, yet the ideal ratio remains unclear.

Optimal fertilizer rates towards the improvement of nitrogen use

Based on 10 years of field monitoring and experiment, this study used optimum fertilizer rates (30% N reduction) to evaluate nitrogen use efficiency (NUE) and N export in the Chao Lake watershed of paddy rice-wheat rotational farming.

High-nitrogen compound fertilizers, characterized by high nitrogen concentrations, are designed to rapidly promote plant growth. When applying these fertilizers, it is essential to determine the appropriate nitrogen content based on factors such as crop type, soil conditions, and climatic environments. The following analysis provides detailed recommendations on nitrogen levels, dosage, timing, precautions, and integration with other fertilizers.

I. Nitrogen Content in High-Nitrogen Compound Fertilizers

High-nitrogen compound fertilizers typically appear as N-P-K (nitrogen-phosphorus-potassium) ternary formulations, with nitrogen accounting for more than 20% of the active ingredients. These fertilizers deliver a rapid nitrogen supply to plants, stimulating leaf growth and enhancing photosynthetic efficiency.

II. Fertilization Guidelines

1. Recommended Dosage: Adjust the application rate according to the crop’s growth stage and soil fertility. Generally, 1–2 kilograms per mu (approx. 0.067 hectares) of high-nitrogen compound fertilizer suffices for most crops. For specialized or nitrogen-demanding varieties, slightly increase the dosage.

2. Timing of Application: Use high-nitrogen fertilizers as base or topdressing fertilizers. Apply during early spring (to kickstart growth) or after autumn harvest (to replenish nutrients). Avoid application during hot seasons to prevent root burn from concentrated fertilizer.

3. Combination with Other Fertilizers: Pair high-nitrogen formulas with phosphorus and potassium fertilizers to promote root development and disease resistance. Additionally, integrate micronutrient fertilizers to ensure balanced nutrition for plants.

III. Key Precautions

1. Avoid Overapplication: Excessive nitrogen may lead to excessive vegetative growth and delayed maturity, harming yield and quality. Strictly control dosages.

2. Soil pH Considerations: Crop preferences and soil pH levels dictate fertilizer choice. Adjust application rates and methods based on soil acidity or alkalinity.

3. Environmental Factors: Refrain from applying during rainy days, extreme heat, or nighttime, as these conditions may disrupt plant absorption or cause nutrient loss.

high-nitrogen compound fertilizers are efficient tools for accelerating plant growth. careful attention to dosage, timing, and environmental compatibility ensures optimal results. Proper use enhances crop health, yield, and quality.
