1、Phosphorus fertilizer: from commodity to speciality — from fertilizing

Given the nonrenewable nature and low use efficiency of P, the development of speciality P-fertilizers and improved application methods are essential for reducing environmental P losses and increasing plant P uptake, thereby improving P use efficiency (PUE).

2、Innovative Phosphate Fertilizer Technologies to Improve Phosphorus Use

The technologies presented in detail in this paper were developed to improve the agronomic efficiency of phosphate fertilization in comparison with conventional fertilizers, with costs varying according to raw materials, production technologies, and distance from the consumer market.

3、Exploring phosphorus fertilizers and fertilization strategies for

We advocate for the understanding of plant physiological processes, such as physiological P requirement, storage of excess P as phytate, and plant uptake mechanisms, to identify novel ways of designing and delivering P fertilizers to plants for improved uptake.

4、Compound Fertilizers

Complex fertilisers are normally made by drying a wet slurry, containing the appropriate raw materials, on a fluid bed system to produce granules, each containing the declared nutrients in the correct ratio, size 2–5 mm diameter.

Phosphorus Fertilizers

As the fertilizer reaches the soil, available soil moisture begins to dissolve the fertilizer particles, increasing the concentration of inorganic phosphate in solution and diffuses at a short distance from the fertilizer particles (Busman et al., 2002).

Phosphorus Fertilizers: Sources, Benefits, And Application Tips

To help farmers, food producers, and input suppliers achieve better crop yields and healthier soil, we’ve compiled this detailed guide to phosphorus fertilization.

Determination of Phosphate in fertilizers

This protocol outlines the photometric determination of phosphate in fertilizers using the phosphorus molybdenum blue method following acid extraction. The method offers a cost-effective approach for assessing phosphate content in fertilizer samples to ensure quality and prevent issues like eutrophication caused by excessive phosphorus in the soil.

6 Key Fertilizer Production Technologies Explained

In the ever-evolving landscape of agricultural production, understanding the 6 main fertilizer process technology and production process is crucial. This article delves into the intricate methods that transform raw materials into essential nutrients, highlighting innovations that enhance efficiency and sustainability.

Compound phosphate fertilizers are nutrients-rich fertilizers containing essential elements like nitrogen (N), phosphorus (P), and potassium (K), commonly used to supplement plants' nutritional needs. Proper application of these fertilizers can significantly improve crop yields and quality. Below are the key methods for using compound phosphate fertilizers:

1. Choosing the Right Compound Phosphate Fertilizer

When purchasing, ensure the fertilizer matches the crop type. Different crops have varying phosphorus requirements. For example, rice may need higher nitrogen, while corn requires more phosphorus.

2. Determining the Application Rate

Based on soil tests and crop demands, calculate the dosage per mu (approx. 0.067 hectares). Typically, apply 1-3 kg per mu, adjusted for local climate, soil type, and crop variety.

3. Timing of Application

Apply according to crop growth stages:

• Early stages (e.g., germination, seedling growth): Increase phosphorus to promote root development and sturdy growth.
• Later stages (e.g., flowering, maturity): Reduce phosphorus to avoid compromising fruit quality.

4. Application Methods

Common methods include:

• Furrow application: Spread fertilizer in trenches and bury it.
• Hole application: Place fertilizer directly into holes near roots.
• Strip/band application: Apply in rows or bands.

5. Application Depth

For most crops, apply at 20-30 cm depth. Deeper application improves efficiency but avoid over-depth to prevent root damage.

6. Post-Application Management

• Water immediately after application to aid absorption.
• Monitor crop health and adjust strategies if abnormalities arise.

7. Precautions

• Avoid overapplication: Excess phosphorus can acidify soil and disrupt its structure.
• Combine with organic fertilizers: Enhance efficiency and soil health.
• Environmental protection: Prevent runoff into water bodies to avoid pollution.

rational use of compound phosphate fertilizers—through proper selection, dosage, timing, and methods—maximizes crop productivity while safeguarding soil and environmental health.
