  • NPK25-30-25s

NPK25-30-25s
NPK25-30-25+S is a high-analysis, fully water-soluble compound fertilizer with a nutrient ratio of 25% Nitrogen (N), 30% Phosphorus (P₂O₅), and 25% Potassium (K₂O), enriched with Sulfur (S). This formulation is specifically designed to address the high nutritional demands of crops during critical growth stages such as transplanting, flowering, and fruit setting. The elevated phosphorus content promotes robust root development and energy transfer, while the balanced nitrogen and potassium support vigorous vegetative growth and high-quality yield. The addition of sulfur enhances nitrogen efficiency and overall plant metabolism. Ideal for fertigation and foliar application, this fertilizer ensures maximum nutrient uptake and optimal crop performance.

Product Details

2.1 Key Features

High Nutrient Density: Offers one of the highest concentrations of NPK among water-soluble fertilizers, providing more nutrients per kilogram.
Phosphorus-Rich Formulation: The 30% phosphorus content is exceptionally high, making it a powerful tool for stimulating root growth and flowering.
Balanced N and K: The 25% nitrogen and 25% potassium provide a strong foundation for vegetative growth and fruit quality, complementing the high phosphorus.
Sulfur Enrichment: Sulfur is included to improve protein synthesis and the efficiency of nitrogen utilization.
Excellent Solubility: Dissolves completely in water, leaving no residue, ensuring uniform distribution in fertigation systems.

Chloride-Free: Safe for use on chloride-sensitive crops.

2.2 Primary Functions and Benefits


FunctionBenefit to PlantsAgronomic Advantage
Enhanced Root DevelopmentThe high phosphorus content stimulates the growth of a strong, extensive root system.Improves water and nutrient absorption, leading to better plant establishment and drought tolerance.
Promoted Flowering & FruitingPhosphorus is vital for energy transfer (ATP) during flowering and fruit set.Increases the number of flowers, improves fruit set percentage, and reduces flower and fruit drop.
Balanced Vegetative GrowthNitrogen supports leaf and stem development, while potassium regulates overall plant functions.Ensures a healthy, vigorous canopy that can support a high yield of quality fruits or grains.
Improved Nutrient Use EfficiencyThe synergistic effect of NPK and sulfur ensures that nutrients are utilized effectively.Maximizes the return on fertilizer investment and promotes sustainable farming practices.


2.3 Target Crops and Application Scenarios
Transplanting Stage: For tomatoes, peppers, cucumbers, cabbage, and strawberries, application at transplanting helps reduce transplant shock and promotes rapid root establishment.
Flowering and Fruit Setting Stage: Essential for fruit trees (citrus, apples), grapes, melons, and squash to support the high energy demands during these critical phases.
Bulking and Tuber Initiation: For potatoes, carrots, and other root crops, it supports the development of uniform, high-quality tubers and roots.
High-Value Cash Crops: Ideal for tobacco, cotton, and flowers where a strong start and high-quality yield are paramount.
2.4 Application Guidelines (General)
Fertigation (Recommended):
Dilution: Dissolve 5-8 kg of NPK25-30-25+S in 1000 liters of water.
Application Rate: Apply 5-10 kg per hectare per application. During peak demand periods (e.g., flowering), applications can be made every 7-14 days.
Foliar Spray:
Dilution: Dissolve 2-3 kg in 1000 liters of water.
Spray: Apply evenly on leaves, focusing on the underside where absorption is most efficient. Avoid application during the hottest part of the day.
Compatibility: Can be mixed with most water-soluble fertilizers. However, due to its high phosphorus content, avoid mixing with concentrated calcium solutions without prior testing to prevent precipitation.

3. Nutrient Role Summary

NutrientSymbolContentPrimary Role in Plant Growth
Total NitrogenN
25%Promotes vigorous vegetative growth, essential for protein and chlorophyll synthesis.
Phosphorus (P₂O₅)P30%Critical for root development, energy transfer, flowering, and fruiting.
Potassium (K₂O)K25%Enhances fruit quality, regulates water uptake, and improves disease resistance.
SulfurSVariable (e.g., 1-3%)Improves nitrogen efficiency, essential for amino acid and protein synthesis.


Note: NPK25-30-25+S is a specialized, high-performance fertilizer designed for situations where crops require a significant and balanced nutrient boost. Its high concentration makes it particularly cost-effective for fertigation systems, as less product is needed to achieve the desired nutrient levels. This fertilizer is best used during the most critical phases of crop development to maximize yield potential and quality.
