Potassium dihydrogen phosphate (KH2PO4) is a versatile fertilizer with high nutrient content and excellent absorption. It performs exceptionally well in the field and is widely used in various economic crops, grains, fruits, and vegetables. It can also be combined with other fertilizers for enhanced effects. Here, we discuss the optimal combinations for potassium dihydrogen phosphate and how to use them effectively.
Best Combinations for Potassium Dihydrogen Phosphate
1. Potassium Dihydrogen Phosphate + Chlormequat
Chlormequat is a regulator that inhibits excessive vegetative growth and promotes reproductive growth in crops. When combined with potassium dihydrogen phosphate, it helps control overgrowth and improve crop yield. Mix the two according to recommended doses for best results.
2. Potassium Dihydrogen Phosphate + Glucose Titanium
Adding glucose and glucose titanium to potassium dihydrogen phosphate foliar fertilizer enhances the sweetness and coloration of fruits. Glucose increases sweetness, while glucose titanium boosts both sweetness and color development, making fruits more marketable. Use this combination during fruit development for optimal results.
3. Potassium Dihydrogen Phosphate + Micronutrients (Calcium, Magnesium, Boron, Zinc, Iron)
Mixing potassium dihydrogen phosphate with micronutrients like calcium, magnesium, boron, zinc, and iron meets the crops' nutrient needs and prevents issues like fruit cracking and deformities. This combination is beneficial for fruits and vegetables such as tomatoes, cucumbers, strawberries, grapes, and peaches.
4. Potassium Dihydrogen Phosphate + Brassinolide and Pyraclostrobin
Adding brassinolide and pyraclostrobin to potassium dihydrogen phosphate solutions makes crops more robust and disease-resistant. This combination also helps repair damage from mechanical injuries, fertilizer burn, and pesticide damage. Use this mix during stressful periods for the plants.
5. Potassium Dihydrogen Phosphate + Glucose
When spraying foliar fertilizers on vegetables and fruits, adding glucose promotes fruit maturation and development, improves quality, and increases sweetness. It also enhances disease resistance and immunity in crops. Use this combination regularly during the growing season.
6. Potassium Dihydrogen Phosphate + Paclobutrazol
Adding paclobutrazol to foliar fertilizers promotes reproductive growth, stimulates overall growth and development, inhibits vegetative growth, and controls excessive growth. It also enhances flower bud differentiation and crop development. Apply this mix during the early growth stages of crops.
7. Potassium Dihydrogen Phosphate + Brassinosteroid
Adding brassinosteroid to potassium dihydrogen phosphate solutions promotes tillering, flower bud differentiation, increases flowering and fruiting, and boosts yield. It also enhances the crop's resistance to drought, frost, injury, and aging. Use this combination to improve crop resilience.
8. Potassium Dihydrogen Phosphate + Sulfur Boron Fertilizer
During the flowering period of crops such as trees, peanuts, soybeans, rapeseed, and various fruits and vegetables, adding ordinary boron fertilizer or sulfur boron fertilizer to potassium dihydrogen phosphate foliar fertilizer promotes fruit development, flower and fruit retention, and increases yield. Apply this mix during the flowering stage for best results.
9. Potassium Dihydrogen Phosphate + Urea
This combination ensures that the foliar fertilizer contains complete NPK (nitrogen, phosphorus, potassium) nutrients, meeting the crops' needs for these essential elements. Phosphorus and potassium fertilizers promote strong seedlings and increase crop yield, while nitrogen fertilizer significantly boosts seedling growth and development. Use this mix for balanced nutrient supply throughout the growing season.
Conclusion
Using these optimal combinations with potassium dihydrogen phosphate can significantly enhance crop growth, yield, and quality. Farmers can experiment with these combinations in their production processes to achieve better results.
