Product Introduction
Macro Element Water Soluble Fertilizer supplies balanced nitrogen, phosphorus and potassium together with chelated micronutrients. Nutrients dissolve rapidly in water and can be taken up efficiently by crop roots and leaves. It satisfies crop nutrient demands during key growth stages, boosts vegetative and reproductive development, and stabilizes yield formation. As a core raw material for fertigation and foliar feeding formulations, it supports precise nutrient management for modern intensive planting.

Health Benefits & Values
Balanced Macro Nutrient Supply
Delivers nitrogen, phosphorus and potassium in adjustable ratios to match nutrient requirements at different crop growth phases.
Rapid Nutrient Dissolution
Fully soluble crystal structure enables fast nutrient availability for root absorption.
Promote Vegetative & Reproductive Growth
Nitrogen supports foliage growth; phosphorus aids root and flower formation; potassium enhances fruit development and crop vigor.
Prevent Crop Nutrient Deficiency Disorders
Supplies essential macro nutrients and chelated trace elements to correct yellowing, poor flowering and fruit malformation.
Optimize Fertigation Efficiency
Low insoluble content avoids drip nozzle blockage, adapting to continuous precision irrigation systems.
Core Value in Formulation Development
High Purity Low-Insolubility Raw Material
Low impurity content and excellent solubility reduce sediment risk in finished fertilizer.
Customizable NPK Ratio for Targeted Formulas
Flexible nutrient proportioning allows developers to tailor products for specific crop growth stages.
Perfect Compatibility With Fertigation Systems
Fine crystal particle size and fast dissolution suit drip irrigation, sprinkler irrigation and foliar spray formulations.
Good Synergy With Organic Functional Additives
Macro Element Water Soluble Fertilizer compatible with amino acids, chitosan oligosaccharide and other bio-stimulants to create compound functional water-soluble fertilizers.
Stable Physical Properties During Storage
Low moisture absorption under proper storage, preventing caking and maintaining consistent nutrient content.
End-Application Scenarios
Precision Drip & Flush Fertigation (Core Track)
Used in greenhouse and field fertigation to deliver targeted NPK nutrition throughout crop growing cycles.
Foliar Nutrient Supplement
Foliar spraying during peak nutrient demand periods to quickly correct nutrient shortage and sustain growth.
Stage-Targeted Crop Management
Formulated into different NPK ratio variants for specific growth stages.
Compound Functional Water-Soluble Fertilizer Development
Serves as primary nutrient base to combine with bio-stimulants, amino acids or trace elements for multi-functional fertilizer lines.
Large-Scale Commercial Crop Production
Widely applied for vegetables, fruit trees, grains and cash crops in intensive modern planting systems.
Application Advantages and Market Positioning
High-Purity Water-Soluble NPK Base Material
Different from traditional granular compound fertilizers, Macro Element Water Soluble Fertilizer is designed for liquid fertigation and rapid nutrient supply.
Customizable Nutrient Matching
Adjustable NPK ratios meet differentiated crop demands, bringing flexible product development options for formulators.

FAQ (Technical Q&A)
Q1: How does this product differ from conventional granular compound fertilizers?
A: Unlike granular fertilizers that rely on soil dissolution, this product is fully water-soluble and designed for fertigation and foliar application. It provides rapid nutrient availability at key growth stages with precise NPK management.
Q2: What is the optimal application rate for drip irrigation and foliar spray?
A: For drip irrigation, dilute 500–800 times; apply 3–5 kg per mu per application. For foliar spray, dilute 800–1000 times. Adjust based on crop type, growth stage, and soil nutrient status.
Q3: Can it be tank-mixed with amino acid or chitosan oligosaccharide fertilizers?
A: Yes. It is compatible with amino acids, chitosan oligosaccharide, and neutral bio-stimulants. Avoid mixing with strongly alkaline materials. A small-scale jar test is recommended before large-volume mixing.
Q4: What is the difference between EDTA and EDDHA chelated trace elements?
A: EDTA is cost-effective and suitable for acidic to neutral soils. EDDHA is more stable at high pH (above 7) and is preferred for calcareous soils. Choose based on soil pH and crop requirements.
Q5: Can it be used together with microbial inoculant fertilizer?
A: They can be applied alternately. High-concentration mineral salts may affect microbial activity, so direct tank mixing is not recommended. Apply microbial fertilizer separately, preferably 5–7 days apart.
Q6: What are the key precautions for storage and handling?
A: Store sealed in a cool, dry, ventilated warehouse away from moisture to prevent caking. Keep away from strong alkaline substances. Shelf life is typically 2 years under proper conditions.
Q7: Is this product approved for organic agriculture?
A: It depends on raw material source and local organic certification standards. Some high-purity grades are permitted for organic programs. Check with local certification bodies for approval status.
Q8: What is the difference between macro element and amino acid water soluble fertilizers?
A: Macro element fertilizer mainly provides inorganic NPK nutrition. Amino acid fertilizer supplies small-molecule organic nutrition and physiological regulation. They are commonly combined in fertigation programs for balanced nutrition and stress recovery.
Q9: Does high NPK concentration cause salt stress to crops?
A: At recommended dosages, salt stress risk is low. Overuse may cause salt accumulation in the root zone, especially for sensitive crops. Follow label recommendations and monitor soil EC levels.
Q10: What is the core market positioning of Macro Element Water Soluble Fertilizer?
A: As the foundational high-purity water-soluble nutrient raw material for modern precision agriculture, it delivers adjustable NPK nutrition for fertigation and foliar application. With excellent solubility and customizable nutrient ratios, it acts as the core base material for developing diversified water-soluble fertilizer products.
