Timing for Using Bone Meal and Potassium Fulvic Acid Initial Application: Before using potassium fulvic acid, apply bone meal to adjust soil pH and improve soil structure.

Frontiers

Abstract Potassium and fulvic acid (FA) fertilizer applications are two important measures for improving cotton growth. However, there are few studies on the application interactive effects of controlled-release potassium chloride (CRK) in combination with FA on cotton production.

Potassium fulvic acid and brassinolide are two common plant growth regulators that play crucial roles in agricultural production. Potassium fulvic acid is an organic compound fertilizer rich in various nutrients, which enhances soil fertility and water retention. Brassinolide, a plant growth regulator, promotes plant growth and development. The optimal application timing and methods for these substances in agriculture are as follows:

1. Optimal Timing for Potassium Fulvic Acid Application

Potassium fulvic acid is typically applied in spring and autumn, when temperatures are moderate and conducive to its decomposition and absorption. Specifically:

• Spring application: Late March to early April, during the spring plowing season. This improves soil fertility and water retention, providing adequate nutrients for crop growth.
• Autumn application: Mid-September to early October, during the autumn harvest period. This promotes crop growth and fruit maturation.

2. Optimal Timing for Brassinolide Application

Brassinolide, a versatile plant growth regulator, can be used throughout the crop lifecycle, including:

• Pre-sowing: Enhances seed germination rates and seedling stress resistance.
• Growth stage: Stimulates crop growth and increases yield.
• Pre-harvest: Extends crop freshness and improves quality. Application timing should be adjusted based on specific agricultural needs.

3. Application Methods for Both Substances

(1) Application Methods for Potassium Fulvic Acid

• Basal application: Mix potassium fulvic acid with soil and deeply plow to ensure full absorption. Suitable for large farmlands.
• Topdressing: Apply based on crop needs and soil fertility:
  • Early growth: 5–10 kg/mu.
  • Mid-growth: 10–20 kg/mu.
  • Late growth: 20–30 kg/mu.
• Foliar spraying: Dissolve potassium fulvic acid in water and spray on leaves to boost photosynthesis and nutrient uptake. Particularly effective for fruits, vegetables, and other crops.

(2) Application Methods for Brassinolide

• Spraying: Dissolve brassinolide in water and spray on leaves to enhance photosynthesis and nutrient absorption. Ideal for fruits and vegetables.
• Soaking: Soak seeds in a brassinolide solution to improve germination and seedling growth. Suitable for seeds or young plants.
• Topical application: Apply directly to crop surfaces to accelerate growth and stress resistance. Effective for fruits, vegetables, and other crops.

Key Considerations

• Adjust application timing and dosage based on crop requirements and soil conditions.
• Avoid excessive use to prevent issues like soil salinization.

By following these guidelines, potassium fulvic acid and brassinolide can significantly enhance agricultural productivity while maintaining soil health.
