Humic acid fertilizer

1.Granular Humic Acid Fertilizers

Humic acid (including humic acid, humic acid, and fulvic acid) usually accounts for 10%-60% and is the key to determining the effectiveness of fertilizers. It is often combined with macroelements such as nitrogen, phosphorus, and potassium (such as N+P₂O₅+K₂O≥15%) or trace elements (calcium, magnesium, iron, etc.) to form a compound formula of “humic acid + nutrients.”

Features and Benefits

Improves soil quality: Promotes the formation of aggregate structures, enhances air permeability in heavy clay soils, and water and fertilizer retention in sandy soils. Long-term use can alleviate compaction.
Improves fertilizer efficiency: Combines nitrogen, phosphorus, potassium, and trace elements to reduce leaching (prevents phosphorus fixation) and prolongs fertilizer effectiveness; fulvic acid aids root nutrient absorption.
Enhances stress tolerance: Regulates cellular osmotic pressure, promotes root development, helps crops withstand drought, salinity, and low temperatures, and enhances disease resistance.
Improves quality: Promotes photosynthesis and the accumulation of sugars and amino acids, enhancing fruit sweetness, color, and storage durability, while reducing the incidence of malformed fruit.
Advantages of granules: Easier mechanized fertilization (broadcasting or hole application) than powders, produces no dust, and releases nutrients evenly and slowly, preventing root burn.

2. Liquid Humic Acid Fertilizers

It is mainly composed of humic acid, usually containing humic acid ≥30g/L, and also adds a large number of elements such as nitrogen, phosphorus, potassium, etc., generally ≥200g/L. Some products are combined with trace elements such as boron, zinc, copper, as well as natural active substances such as biochemical amino acids, bio-acids and endogenous hormones.

Features and Benefits

Fully water-soluble and easily absorbed: It completely dissolves in water, forming a uniform solution that can be directly absorbed and utilized by crop roots and leaves with high absorption efficiency, quickly meeting the crop’s nutritional needs.
Comprehensive Nutrients: Contains a variety of nutrients, including humic acid, nitrogen, phosphorus, potassium, and trace elements, creating a synergistic nutritional effect and providing comprehensive nutritional support for crops.
Improves Soil: It can increase soil organic matter content, balance soil pH, reduce soil salinization, improve soil buffering capacity, promote the formation of soil aggregate structure, and increase soil aeration and water retention.
Enhanced Stress Resistance: It can enhance crop resistance to drought, cold, disease, and stress, improve crop immunity, promote crop growth and development, improve crop quality, and increase crop yield.

Humic acid - a balanced supply of macronutrients

Humic acid: Improves soil quality, conserves water, increases nutrient utilization, promotes root resilience, helps crops accumulate beneficial substances, and improves agricultural product quality.
Nitrogen: Promotes leaf and stem growth, aids photosynthetic production of organic matter, increases crop tillering and branching, and maintains vigorous growth.
Phosphorus: Promotes root resistance to cold, accelerates flowering, budding, and fruiting, and aids nutrient absorption and biosynthesis and transport.
Potassium: Strengthens crop resilience and prevents lodging, promotes the transport of photosynthetic products to harvesting organs, and improves water utilization and fruit quality.

The difference between granular humic acid and liquid humic acid

	Granular Humic Acid Fertilizer	Liquid Humic Acid Fertilizer
Physical Form & Solubility	Granular (1-5mm diameter), slowly soluble/ slightly soluble; decomposes gradually in soil	Liquid (clear/ brown suspension), 100% water-soluble; forms uniform solution directly
Nutrient Release Rate	Slow and long-lasting; fertilizer effect lasts 2-3 months typically	Fast and immediate; nutrients absorbed directly by crops (takes effect in 1-3 days)
Core Function Focus	Primarily soil improvement (repairing compaction, enhancing water/fertilizer retention), supplemented with long-term nutrient supply	Primarily rapid nutrient supplementation (emergency nutrient supply, relieving nutrient deficiency), supplemented with soil conditioning
Application Method	Suitable for base fertilizer (broadcasting, row application), topdressing via hole/ditch during growth period; requires mechanical assistance	Suitable for foliar spraying, drip irrigation/sprinkler irrigation (integrated water-fertilizer), root drenching, seed soaking/dressing
Applicable Scenarios	Field crops (wheat, corn), orchard base fertilizer, improvement of saline-alkali/compacted soil	Cash crops (fruits, vegetables, flowers), topdressing during crop growth, stress resistance promotion in drought/cold periods
Dosage & Convenience	High per-mu dosage (50-150kg); higher transportation/fertilization cost; low dust emission	Low per-mu dosage (5-10kg); used after dilution; lightweight and easy to transport; suitable for precise fertilization
