Mineral Source Humic Acid Powder as Premium Organic Fertilizer Raw Material

Humic Acid (CAS No.1415-93-6) is a natural macromolecular organic compound formed by long-term decomposition and transformation of animal and plant residues under the action of microorganisms in soil, peat, lignite and weathered coal. Our industrial grade humic acid organic fertilizer raw material is extracted from high-quality low-sulfur lignite/weathered coal through advanced alkaline extraction, acid precipitation and purification processes, with humic acid content ranging from 60% to 85% according to different grades. The finished product presents as black-brown fine powder or flake, odorless, with strong adsorption, ion exchange and chelating capabilities, rich in carboxyl, hydroxyl, phenol hydroxyl and other active functional groups. It is insoluble in water but soluble in alkaline solution, with excellent water retention, soil improvement and nutrient activation properties, widely used as core raw material for organic fertilizer, compound fertilizer, water-soluble fertilizer and soil conditioner, complying with GB/T 11957-2001 national standard for humic acid products and NY 1106-2010 standard for organic fertilizer raw materials.

Applications
**Organic & Compound Fertilizer Production**: The most popular functional raw material for organic fertilizer formulation, compound fertilizer and bulk blending fertilizer. Mixed with animal manure, crop straw and bean pulp to raise organic content of finished fertilizer; chelate nitrogen, phosphorus, potassium and medium trace elements to lock nutrients, reduce soil fixation and rain leaching loss, greatly boost fertilizer utilization efficiency. It also serves as natural granulation binder to strengthen fertilizer particle hardness and cut dust during processing.
**Saline-Alkali & Compacted Soil Improvement**: Efficient soil conditioner for hardened farmland, acidified soil and saline-alkali wasteland. It optimizes soil aggregate structure to loosen compacted earth, improve soil air permeability and water retention capacity; buffer soil pH to neutralize excessive acid or alkali, lower soil surface salt accumulation. Meanwhile it immobilizes heavy metal elements in contaminated farmland, reduce crop heavy metal uptake and realize soil remediation.
**Water Soluble & Foliar Fertilizer Intermediate**: After alkali neutralization to produce potassium humate, sodium humate and ammonium humate, it turns into key raw material for drip irrigation fertilizer and foliar spray fertilizer. Active humic acid can stimulate crop root germination, increase fibrous root quantity, enhance crop drought resistance, cold resistance and disease resistance, widely used for fruits, vegetables, grain and cash crops.
**Livestock Feed & Aquaculture Industry**: Used as green feed additive for pig, poultry and ruminant feed to improve intestinal environment, promote nutrient absorption and reduce animal diarrhea rate. In aquaculture ponds, it adsorb redundant ammonia nitrogen, nitrite and harmful heavy metals in water body, purify breeding water and stabilize water quality.
**Other Industrial Fields**: Applied as wastewater treatment adsorbent to capture organic pollutants and heavy metal ions; also used as coal briquette binder and ceramic additive in relevant manufacturing industries.
