Potassium is one of the essential nutrients for plant growth and plays a critical role in the development of fruit trees and the quality of fruits. Potassium enhances the activity of various enzymes in plants, improves drought, cold, and pest resistance, while also increasing photosynthetic efficiency, sugar accumulation, and taste. proper application of potassium fertilizers is significant for improving fruit yield and quality.

Commonly used potassium fertilizers in fruit production include potassium chloride (KCl), potassium sulfate (K₂SO₄), and potassium dihydrogen phosphate (KH₂PO₄). Among these, potassium chloride is the most widely used due to its lower cost, ease of transportation, and storage. Potassium sulfate and potassium dihydrogen phosphate are more expensive but contain higher amounts of potassium and better solubility, making them suitable for topdressing or foliar spraying.

1. Potassium Chloride (KCl)

Potassium chloride is an inorganic potassium fertilizer absorbed by plants through cation exchange with soil calcium. It is suitable for all soil types, including acidic, neutral, and calcareous soils. KCl promotes tree growth and fruit quality, enhancing stress resistance and yield. its poor solubility requires mixing with water before use. Excessive use may lead to soil acidification and disrupt microbial activity.

2. Potassium Sulfate (K₂SO₄)

Potassium sulfate, an organic potassium fertilizer, consists of sulfate ions. It is ideal for acidic soils, as sulfate ions combine with calcium to form soluble calcium sulfate, improving water retention and soil aeration. K₂SO₄ boosts disease resistance and fruit quality but is costly, hygroscopic, and prone to clumping.

3. Potassium Dihydrogen Phosphate (KH₂PO₄)

This compound fertilizer contains both phosphorus and potassium. Suitable for all soil types, especially acidic ones, it enhances stress resistance and yield. its low solubility necessitates dilution with water, and overuse may disrupt soil pH balance.

Factors to Consider When Choosing Potassium Fertilizers:

1. Soil Type: Match fertilizers to soil. For example, KCl works well in acidic soils, while K₂SO₄ is better for neutral or alkaline soils.
2. Tree Varieties: High-demand trees like apples or pears require potassium-rich fertilizers.
3. Application Method:
   • Topdressing: Apply via irrigation systems for root absorption.
   • Foliar Spraying: Spray diluted solutions on leaves for quick uptake.
4. Timing:
   • Base Fertilization: Apply before planting as the primary potassium source.
   • Supplementary Applications: Adjust based on growth stages and soil conditions.

selecting the right potassium fertilizer and application method is crucial for optimizing fruit yield and quality. Decisions should consider local soil conditions, tree types, and fertilization practices to achieve the best results.
