1、Maximising cotton phosphorus utilisation for zero surplus and high

Furthermore, we proposed a strategy of using starter P combined with ammonium sulfate fertigation after the plant emergency, and concentrated application of acidic P fertiliser with the pursuit of ammonium sulfate could achieve high cotton yields and P fertiliser efficiency.

2、Drip Irrigation of Phosphorus Fertilizer Enhances Cotton Yield and

To identify optimal P fertilization strategies, a consecutive two-year field experiment (2023–2024) under mulched drip irrigation was conducted. Three P application methods were tested: no P (CK), basal P application (PB), and drip P application (PD).

Basal and topdressing application technology of phosphate fertilizer for high cotton yield and high phosphorous efficiency in Xinjiang [J]. Journal of Plant Nutrition and Fertilizers, 2018, 24 (1): 146-153.

Effect of Applying Different Forms and Rates of Phosphoric Fertilizer

Abstract: In this paper, the effects of two phosphorus fertilizers and their different concentrations on soil, phosphorus efficiency of plant on the whole growth period and yield for cotton were studied by field experiment.

Phosphorus High

The plant-available soil phosphorus rate and methods for applying phosphatic fertilizer and soil P-fixation capacity are critical factors for lower cotton productivity in Southern Punjab,...

Phosphorus fertilizer recommendation based on minimum soil surplus for

For example, maintaining soil available P content at the optimum critical agronomic level with fertilizer can achieve 80–90% of potential yield for cotton, maize and wheat with a high P use efficiency.

Fertilizer Role in Sustainable Cotton Production

Fertilization for sustainable cotton production is a farming systems problem. Better yields and quality in cotton require balanced nutrition, based on accurate fertility information and integrated farm planning.

Fertilizer dose in cotton and timing of application

This article aims to delve into the importance of fertilizers in cotton cultivation and guide farmers on optimal fertilizer dose and the recommended timing for application.

Optimizing Phosphatic Fertilizer Drip Timing to Improve Cotton

We conducted a field experiment using a completely randomized design to adjust the timing of phosphatic fertilizer application and apply the same amount of pure phosphorus.

Cotton is an important cash crop with high nutritional demands during its growth. Phosphate fertilizer, as a supplementary nutrient alongside nitrogen and potassium, plays a critical role in cotton development and yield. Below is a detailed guide on the proper use of phosphate fertilizer for cotton:

I. Understanding Cotton’s Phosphorus Needs

Phosphorus is essential for promoting root development, enhancing photosynthetic efficiency, and improving disease resistance in cotton. It strengthens root systems, improves soil water-and-nutrient retention, and boosts photosynthesis, ultimately increasing growth rates and yields.

II. Selecting the Right Phosphate Fertilizer

When choosing phosphate fertilizers, consider factors such as type, phosphorus content, and source. Common options include:

• Phosphate rock: Suitable for all soil types but with lower phosphorus content.
• Superphosphate (single superphosphate): High phosphorus content, ideal for acidic soils.
• Triple superphosphate: Even higher phosphorus content, also suited for acidic soils. Select fertilizers based on cotton growth stages and soil conditions.

III. Rational Fertilization Practices

1. Timing: Apply phosphate fertilizer early and deeply.

   • Early stages (budding and flowering periods): Promote growth.
   • Late stages (boll formation and maturation): Enhance boll development and yield.

2. Dosage: Apply 5–10 kg per mu (adjust based on growth stage and soil conditions). Excessive use may cause overgrowth, reducing quality and yield.

3. Application Method:

   • Mix with organic fertilizers to improve efficiency.
   • Avoid direct contact with cotton plants to prevent tissue damage.

4. Depth:

   • Early growth: Apply near surface.
   • Late growth: Gradually increase depth to encourage root expansion.

IV. Key Considerations

1. Avoid overapplication: Excess phosphorus disrupts growth balance.
2. Combine with other fertilizers: Pair with nitrogen and potassium for optimal results.
3. Soil testing: Analyze soil pH and nutrient levels before application to refine dosage and methods.

Proper phosphate management is vital for cotton productivity. By understanding cotton’s phosphorus needs, selecting suitable fertilizers, applying rationally, and following key precautions, farmers can significantly improve both yield and cotton quality.
